How To Properly Cut A Gas Cylinder

How to disassemble a gas cylinder: Step-by-step instructions for precautions

Surely, you have often wondered what can be done from an old gas cylinder? The amateur will take the receiver for Waste scrap metal and send it to the landfill, but only a real master will be able to use the container as the basis for a new product.

Agree, a used gas cylinder is an ideal case for a homemade barbecue, smokehouse, boiler or even fireplace. Detailed instructions will help even a beginner quickly understand how to disassemble a gas cylinder as safely as possible.

Disassembling the receiver requires the master to comply with the fundamental rules applied for the safe cutting of a container in which flammable materials were stored. We have compiled detailed instructions for disassembling a propane cylinder, which describes step by step how to free the container from gas residues and cut correctly.

Removing the cylinder valve

Further, it is recommended to unscrew the valve with the subsequent removal of the pins and the fixing element. This is a rather laborious process, since the locking mechanism of the valve is difficult to unwind.

Upon successful completion of the process, a hole with a diameter of 6 mm is formed at the valve site. If you can’t open the valve in any way, then it can be cut off using an ordinary hacksaw for metal.

What is worth Pay attention?

Disassembling even an old gas cylinder requires special care from the master, and the sequence of all actions.

For novice craftsmen who have NOT yet had to deal with sawing a propane receiver, we have prepared some useful tips:

  • The severity of the propane odor when rinsing the cylinder is an indicator of a high probability of fire or explosion;
  • It is better to unscrew the cylinder valve away from living quarters;
  • Cutting a propane cylinder near a fire or any other source of fire is contraindicated;
  • It is forbidden to stand opposite the gas outlet from the receiver, especially in the presence of a characteristic hiss;
  • The markings on the cylinder should be indicated in advance, so that in the end NOT to be mistaken with the calculations.

If there is a pronounced smell of propane, it is better to re-rinse the receiver, and only then proceed to sawing off the valve.

If the smell is still strong, then it is better to postpone the work for a few days and wait until it completely disappears.

Immediately after cutting, the container must be cleaned of old paint, and then thoroughly cleaned with sandpaper to create the most even surface.

The easiest way is to install a flap disc on an angle grinder, which will facilitate further surface treatment, including painting.

Gas receiver cutting

Before starting to cut the cylinder, it is worth considering the thickness of the metal used. On average, the thickness of the steel of the propane receiver is 3-4 mm, while at the joints the indicators can reach 5-6 mm. Almost any angle grinder is suitable for such purposes, however, special attention should be paid to the choice of an abrasive wheel.

In order not to face additional difficulties in the process of cutting the receiver, you can first walk the angle grinder along the markings, using a 1.6 mm thick disc. The next time you cut the metal, you will need to use a wider blade to avoid jamming of the nozzle during the final cut.

Thicker elements, such as joints, can be cut with an angle grinder and then split with a hammer. Acceleration of the process of disassembling a gas cylinder has a detrimental effect on the quality of the final result, therefore it is better to do everything sequentially, AND did not resort to using a chisel or a hammer to cut the joints.

Regardless of the purpose of the gas receiver, the body is prepared according to the instructions provided. From an ordinary propane cylinder, you can make both a stove-stove and a mobile brazier.

It should be understood that to use the receiver body as a barbecue or smokehouse, the outer surface of the structure will need to be coated with non-stick paint, and the inner surface must be burned with a blowtorch.

Gas cylinder flushing

After removing the valve, the gas cylinder is completely filled with water. This is necessary to completely remove gas, which could remain inside the container. The resulting solution from water and gas residues is safe, so it can be safely drained, and not afraid of subsequent fire. However, it is recommended to do this away from structures, since the liquid has a rather pungent odor.

So, by venting the gas and rinsing the cylinder with clean water, all the propane residues were removed from the container. Then you can safely proceed directly to cutting the receiver.

Depending on the features of the future design, markings are made on the surface of the cylinder using chalk. In some cases, cutting is performed along welded seams, which, in turn, are characterized by low strength.

Safety rules when working with an angle grinder

In the process of cutting metal, it is important to take into account the basic rules for the operation of an angle grinder, which allow the master to create the safest conditions for the duration of work.

The features of working with an angle grinder include the following rules:

  • Before starting work with an angle grinder, you must wear a special protective suit made of non-combustible material. It is not recommended to cut metal in clothes with open skin areas, because if fragments hit its surface, a burn may form.
  • Before you start cutting metal, you should pay special attention to the condition of the blade. It is recommended to inspect the nozzle for defects, assess the degree of its wear.
  • Metal cutting is carried out only in goggles, since during the work a huge number of fragments are formed, which fly in different directions, and can cause serious eye injury.

In SEPARATE cases, the steel cutting procedure is divided into several stages. This is necessary when the nozzle heats up during a long cut, which is why it quickly wears out.

In addition, prolonged operation of the angle grinder often leads to malfunctions, which can even lead to injury to the master.

Professional craftsmen recommend using a respirator when working with an angle grinder, since when cutting steel, microscopic fragments of metal can be thrown into the air, settling in the respiratory tract of a person.

Cutaway gas cylinder

A set of tools for work

Disassembly of carbon dioxide or oxygen cylinders is carried out without preliminary preparation, because after bleeding off the gas, these are ordinary metal cylinders, which you can safely cut with an angle grinder. With a propane cylinder, things are a little different, therefore, before carrying out sawing work, the container will have to be prepared.

To do this, you need the following tools:

  • A gas wrench to open the valve to release all the gas from the cylinder;
  • Hand saw for metal for cutting off the neck of the cylinder;
  • Funnel and watering hose for filling the receiver with water;
  • Angle grinder with cutting discs of different thickness.

When working with an angle grinder, you should be especially careful, because in this case the master will have to work with an uneven surface, which can cause the tool to slide off during the metal cutting process.

If you have NOT previously had to work with an angle grinder, it is best to practice on a flat sheet of metal first.

Before starting work, it is recommended to put on a protective cover and goggles, which will serve as reliable protection from fragments and combustible abrasives. An important condition is to choose the right wheel for a specific thickness of the material, because often the discrepancy between the abrasive wheel of the metal can lead to its rapid grinding.

Before you start disassembling a 50 liter gas cylinder, you must open the valve with a gas wrench to completely bleed the gas. The presence of even a small volume of gas inside the container can lead to fire or explosion, therefore, no matter how old the cylinder is, it must be freed from the remaining propane.

Coating the valve with a soapy liquid will help make sure there is NO more gas left in the receiver. You can get rid of gasoline residues only after completely removing the valve.

Using a cut-through gas receiver

Due to the massive connection of all houses to the gasification system, gas receivers have lost their popularity. That is why today many masters set out to make new designs from used cylinders that perform completely different functions.

The first thing that comes to mind when looking for options for using a gas receiver is a homemade potbelly stove. In this case, a propane cylinder is an ideal case for a furnace, since its walls are 3 mm thick, which is just enough for safe operation.

Barbecue grill from a gas cylinder is especially popular. To make such a mobile grill, you need a simple bottle, an old gas stove burner, a grill grate and a tray.

The inner lining of the body allows you to safely cook food in the brazier even with the lid closed A gas grill from a used receiver is ideal for a spacious summer cottage where you can gather a large group of friends.

Several cylinders can be used to build a real smokehouse with separate containers for hot and cold smoking, barbecue and grill compartment. The design can be adapted both for skewers and under the wire rack, which allows you to cook meat and fish in different ways. When making such a complex structure, you should understand the principle of operation of the smokehouse, therefore it is recommended to rely on the drawing.

The process of disassembling an old gas cylinder requires special care on the part of the master, since even a slight residual gas inside the container, when interacting with a spark from an angle grinder, can provoke an explosion. The process of cutting the gas receiver is preceded by a preparatory stage, which includes venting the gas and filling the cylinder with water.

Rules for refueling gas cylinders for summer cottages

A sufficiently high degree of explosion hazard determines the presence of standard requirements for filling gas cylinders.

For example, gas refueling should not be carried out if one of the following disadvantages exists:

  • The equipment is defective;
  • There is final pressure in the cylinder;
  • There are visible defects in the valves or valve;
  • The surface of the cylinder is covered with rust;
  • There are external signs of paint peeling;
  • There are dents or damage.

In addition to the standards, the cylinders are marked with the inscription “compressed gas” and a sticker is applied, signaling an explosion hazard.

Before direct filling, the vessel must be freed from condensate and gas residues. The filling of the cylinder is carried out strictly on the basis of its characteristics specified in the technical passport.

Gas cylinders can be filled in two ways:

  • Exchange. the consumer provides his cylinders and in return receives the cylinders already filled with gas. The main advantage of this method can be considered significant time savings. Disadvantage: receiving someone else’s equipment, which may have lower technical parameters;
  • Using their own cylinders. the consumer leaves the cylinders at the filling station, and after a certain time (1-2 days) picks them up. The positive aspect of this method is that your cylinders are constantly used. Minus. delivery costs and refueling time.

Where to refuel gas cylinders? And where you shouldn’t?

Gas for household cylinders is sold at specialized filling points. Most often, such points are located at stationary automobile gas stations. Of course, the opportunity to fill gas cylinders is available at many gas stations, which are not even equipped with special cylinder points, but experts strongly DO NOT advise purchasing liquefied gas on them. This is associated with certain risks:

  • When refueling with gas, the cylinders are NOT checked for gas leaks;
  • There is no control on the part of refuelers of the timing or period of inspection of cylinders, which makes further operation of cylinders unsafe;
  • The format of an automobile filling station does not make it possible to fill the cylinder properly. According to the approved standards, the volume of filling with gas should not exceed 85%. This makes it possible to create a so-called “steam cap” in the cylinder, which prevents the risk of explosion of the cylinder under the influence of high temperatures (for example, the sun). In automobile gas cylinders, unlike household ones, a special cut-off device is placed to timely prevent gas overflow. Considering this, gas cylinders should be filled with mandatory control of the weight of the equipment on the scales.

Filling gas cylinders at car gas stations is possible only with specialized equipment and a license.

How To Properly Cut A Gas Cylinder

Companies that fill any gas tanks are called “gas filling stations”. By the nature of their activity, they can have various equipment configurations. Often, the process of filling a cylinder can take place in three ways:

  • Pumping. using a pump;
  • Pump-compression. gas is taken by the pump and supplied to the cylinder under the increased pressure created by the compressor;
  • Pump-and-evaporation. an electric heater. evaporator is additionally introduced into the gas supply system, which provides increased pressure.

Such a gas filling station should contain:

  • Exhaust and pumping units;
  • Gas storage tanks;
  • Technical tools for transportation;
  • Additional devices: dispensers, instrument for measuring gas density, etc.

Where to refuel gas cylinders for a summer residence?

Today, refueling gas cylinders is a very topical issue. Especially considering that it is much cheaper and easier to refuel an old cylinder than to purchase a new one. Bottled gas is often used both at home and at work. Most often, gas is used for heating private houses and for household needs (cooking). In connection with the growing popularity of the use of gas in various fields, many people have an expedient question of where to purchase and subsequently refuel gas cylinders for their economic needs.

The cost of refueling gas equipment

The price for such services depends on several factors:

  • Service level (assembly / disassembly)
  • Availability of transport services (additional transportation)
  • Electricity costs for refueling;
  • The cost of the gas itself.

Required tools and materials:

  • Empty propane gas cylinder
  • Hacksaw for metal
  • Funnel and bucket for water or garden hose
  • Empty plastic bottle
  • Angle grinder and face shield for angle grinder

How to empty a gas cylinder

Hello my dear friends and dear guests!
Frankly, I came across a couple of times questions about how you can cut this or that balloon. These are both oxygen and propane cylinders.
I have little experience in this weird business. I will share it with you, maybe it will be useful to someone.

So. I cut propane cylinders, up to five of them. The first one, like the following ones, is confident and NOT afraid of anything. The point is probably that the smell of gas scares us.
But few people know that this is not entirely true, or rather not at all. The gas itself is practically odorless. But the “aroma” from it comes due to the fact that certain ingredients are added to the gas (ethyl mercaptan is added to the gas for the smell),
so that a person smells the smell and realizes that there is a gas leak, there is a danger of fire or explosion!
Now that we have dealt with the smell, we begin the process of cutting the balloon.
For example, we will cut the Chinese. But with the smallest Spark there will be an explosion! Residual gas will explode, even if the cylinder is empty.
What to do? How to get rid of gas residues? Wash? Steaming? Or else how?

I solved this problem very simply. What do we have? GAS. We need to get rid of it, but what if we displace the gas? But with what? And the most common and safe solvent is WATER!
It will collect and absorb the rest of the gas, completely neutralizing it.
Once everything is thought out. we begin!
We take an old and preferably empty bottle. And in Avito the second and DO NOT sell! Take it out into the open field and turn off the valve.
It is advisable not to smoke at this moment, not to be near a fire or open fire and not stand in front of the gas outlet from the cylinder.
The first and second will lead you to a hospital bed, in the latter case, you will “smell” for at least a week.
Well, okay, we bleed off the remaining gas. Then, with pliers, we very carefully pull out the pins, with which the valve is fixed, fixed from complete eversion.
I bit off the flattened part of the pin, and pulled the pin itself by the cap. Metal is soft and pliable.
Next, we unscrew the valve completely and discard it, we do not need it.

And what do we see? Oh woe! The hole is only 6 mm! How to pour 50 liters of water there?

Again, natural resourcefulness and ingenuity prompted me the right DECISION!
I put the balloon in the neighbor’s car (this is very important! The neighbor himself ran away in horror.) I take a hose, insert a thinner hose into it, about 5 mm.
And by pouring from one to another, I fill the bottle with water.

Sometimes it is necessary to cut open an old gas cylinder in order to use it with benefit on the farm. For example, a cut gas cylinder can be used as a water reservoir in an autonomous heating system. Due to the design features, the cut cylinder is convenient for lighting a fire in it, it can serve as a hearth for a forge.

There are rules for cutting containers in which flammable materials were stored. In particular, this article will tell you how to spray an old propane gas cylinder.

Order of work

  • Open the cylinder valve as far as it will go and make sure there is NO gas left in it. If there is no sound of escaping gas, it is necessary to soap the outlet of the valve, check that all the gas has escaped.
  • Lay the bottle on its side.
  • Take a hacksaw for metal.
  • Begin to cut the brass valve of the cylinder “under the root”. Brass is easy enough to saw with a hacksaw for metal.
  • Use a friend’s help: while sawing off the valve, a second person should pour water into the sawing site from a plastic bottle or watering hose in order to prevent the appearance of a spark.
  • Having cut the valve, fill the bottle with water. To do this, you can use a bucket (pour water through a funnel) or a long watering hose. Fill the cylinder upwards.
  • As the cylinder is filled, shake it to flush the condensate from the walls.
  • After filling the cylinder, you can drain the water, but not near the house, but somewhere in a garbage dump, since the drained water sometimes emits a strong smell of propane, which does NOT disappear within a few days.
  • After all the actions performed, the cylinder is sawn by the angle grinder. The thickness of the metal is about 3 mm. So sawing shouldn’t be a problem for you.

This is a standard cutting technique for containers that have held combustible materials. Personally, several cylinders have already been cut by this method.

How to properly cut a gas cylinder angle grinder,

Sooner or later, gas containers become unusable, then, in order to give them a second life, you can learn how to cut a gas cylinder, which can become source of heat or a convenient barbecue for summer vacations. In everyday life, a cut cylinder can be useful, but in general it will be source of pollution, which is very harmful to the environment.

Pay attention to

In addition to the many nuances when working with an angle grinder, it is important to know how to reduce the risk of injury and other unpleasant consequences. The tips below will help you with this.

  • Remember. the stronger the propane smell when rinsing, the more likely it is to spark, ignite and explode.!
  • It is advisable to unscrew the valve away from living quarters.
  • It is not recommended to cut metal with a cigarette in your teeth, near a fire or other sources of fire.
  • It is forbidden to stand in front of the gas outlet from the cylinder. Also, experienced people do not advise to visually check the condition of the valve as propane is removed, especially with a characteristic hiss.
  • Remember to precisely mark the place of the future cut. Decide in advance what the cut balloon will turn into, and Proceeding from this Apply the fishing line in black (or in a second noticeable) color.
  • Please note that the cutting area will be slightly narrower after use with the angle grinder.
  • Do not forget about personal protective equipment. gloves, goggles, clothing that covers the sleeves, as well as a respirator.
  • Since the cylinder wall is so thick, the disc of the angle grinder can jam and crack during use, causing injury. If it is possible to use cut-off wheels of different thicknesses, do so. First, the metal is cut with a thicker element (for example, 1.6 mm), then with a thin one (1 mm).
  • If you have not previously had to observe the inner surface of a propane cylinder, know that there is an O-ring. It is located between the concave and cylindrical parts of the container and also requires removal. To remove it, the joint is slightly sawn through (again with an angle grinder).
  • The ring can be removed easily if the inner and outer parts of the cylinder are tightly joined, or with difficulty if connected with a gap. To remove in the latter case, a chisel and a hammer will help.

When working with a gas cylinder, you must observe safety precautions

In short, this is all the information on how to safely cut a propane cylinder. Further actions are at the discretion of the user. The container is used immediately after cutting, or painted, cleaned, etc. To remove the old paintwork and rust, the can is cleaned with a flap wheel, again using an angle grinder. This facilitates further painting or other surface treatment.

How to cut an angle grinder an old gas cylinder

Sometimes it is necessary to cut open an old gas cylinder in order to use it with benefit on the farm. For example, a cut gas cylinder can be used as a water reservoir in an autonomous heating system. Due to the design features, the cut cylinder is convenient for lighting a fire in it, it can serve as a hearth for a forge.

There are rules for cutting containers in which flammable materials were stored. In particular, this article will tell you how to spray an old propane gas cylinder.

How to proceed

After making sure that you have the necessary tools, you can start cutting the used gas cylinder. To do this, perform the following steps:

  • Release the remaining gas from the cylinder. It is necessary to open the valve all the way to make sure there are no gas residues. In the absence of sounds, the outlet of the valve is soaped and the void of the container is assessed by the presence (absence) of “bubbles”.
  • Place the container on its side. It is much more convenient to cut a gas cylinder.
  • Cut off the valve. To do this, they take a hacksaw for metal and cut the brass element with it as close as possible to the place where it joins with the main container. It is advisable to use the help of a second person, who, while you are sawing, pours water over the cut to avoid the appearance of a spark. Cutting the valve with a hacksaw is preferable to an angle grinder, however, it does NOT eliminate the possibility of arcing by 100%.
  • Fill the bottle with water. After removing the valve with a funnel and a hose, the container is filled with liquid. As the volume is filled, the cylinder must be shaken to remove the remaining condensate from the walls. Pour water up.
  • Drain the water. It is best to do this away from the living area as propane residues have a strong unpleasant odor. You can endure it, but the place of the drain will smell for at least a week.
  • Start sawing the container. To do this, the user equips an angle grinder and cuts metal. The thickness of the latter rarely exceeds 4 mm, so the angle grinder will cope with the cylinder in 15-20 minutes.

To minimize the risk of sparking when cutting with the angle grinder, do not wait for the inside of the cylinder to dry, but start working immediately after draining the water. Residual liquid on the walls envelops the propane particles (if any), and also serves as a “lubricant” for the cutting wheel, softening its operation.

If you believe that this is all the information on how to properly and quickly cut a gas cylinder angle grinder, you are mistaken. There are several points that a beginner will never pay attention to, but the master, using them, optimizes his work.

Examples of using cut gas cylinders

Human invention provides many uses for such modified containers, for example:

  • Capacity for an artificial reservoir in the country;
  • Part of the autonomous heating system;
  • Brazier / smokehouse / woodshed;
  • Forge hearth / fireplace.

You can think of other types for using cut gas cylinders. If there was no such work before, then it is best to find out in advance how to cut a gas cylinder, it will be an ideal option, because it will allow Not only imagine, but see the process as it should be.

According to safety rules, there are several main rules for cutting containers in which gaseous substances were previously stored. How to properly cut a gas cylinder you need to know before starting work. this is very important! To perform the required actions, you will need:

  • The actual gas cylinder is naturally empty;
  • Hacksaw for metal work;
  • Construction funnel;
  • Bucket;
  • Watering hose;
  • Angle grinder with protective set.

After all the tools are prepared, you can read the information or look at how to cut the gas cylinder of an angle grinder in order to do all the work quickly and efficiently.

How to cut a gas cylinder angle grinder. Correctly and safely Cutting an old gas cylinder

If your old propane or oxygen cylinder has become unusable, and it is a pity to throw it away, you can try to use it in a subsidiary farm. The body can serve as a good blank for a stove, smokehouse, barbecue, water tanks. Before that, it must be freed from gas residues and cut correctly. To do this, you need to follow a certain procedure.

Oxygen and carbon dioxide cylinders do NOT pose any problems. after bleeding off the residual gas, these are ordinary pieces of iron, which are quietly cut by an angle grinder without any preliminary preparation. With propane, it is already a little more complicated, and the question often arises: how to cut a gas cylinder of an angle grinder? Even with the valves fully open, all the gas will not escape, and the remaining amount will be enough for a small explosion or fire. Therefore, the cylinder must be prepared in advance. To do this, we need the following tools:

  • Open-end or gas valve wrench.
  • Hacksaw for metal.
  • Funnel, watering hose, buckets or other source of water.
  • Angle grinder with discs of different thicknesses and safety glasses.

After that, you can start working. We perform all actions in strict sequence to avoid undesirable consequences.

  • We bleed the gas completely by opening the valve. It is strictly forbidden to be near the outgoing jet at this moment. In addition to the fire hazard, all clothing can smell of gas. We check the presence of pressure in the cylinder with a soap solution, soaping the valve and watch for bubbles.
  • After that, you can proceed to unscrewing the valve. Next steps: carefully Remove the pins holding the valve, and try to Unscrew with a key. On old cylinders, this is not always possible, but if we are lucky, a hole with a diameter of 6 mm will open to us. If the valve DOES NOT lend itself, then just cut it off with a hacksaw for metal. It is advisable that at this moment someone supplied you with water to the place of the cut, or simply direct the stream from the hose. This is necessary to prevent spark formation.
  • Now you can fill the bottle with water through the hole obtained using a funnel or a thin hose. This is called degassing. Water is heavier than any gas, so it displaces residues and dissolves condensate. The resulting gasoline solution is not flammable and can be safely drained.
  • Drain water It is better not near the house, but somewhere in a landfill because of the strong and persistent smell of gas. If the valve did NOT cut off, and the filling went through a small hole, you can supply compressed air to the cylinder to speed up the process. It will create excess pressure and the liquid will flow out in a good stream.
  • Now that most of the liquid has been drained, you can start marking and cutting the balloon. Most often, cutting is done along the welded seams, but for an individual project, you can cut in any direction. The average wall thickness is 3-4 mm, and at the joints 5-6 mm. Any angle grinder can handle this thickness without any problems. To facilitate the work, you can first walk along the cut with a 1.6 mm thick disc, and finally cut through with a thinner disc. This prevents the disc from getting stuck at the exit and breaking it, which could result in injury. In addition, this cutting method is more economical and faster. During work Do not forget about protective equipment.
