How To Cut Metal-Plastic Pipes

Cutting technique

To solve the problem under consideration, it is best to use scissors for cutting metal-plastic pipes. This tool is the most convenient. Cutting with scissors is fairly straightforward. To complete the tasks you will have to make strong physical efforts. The main thing is to perform the operation exactly so that the cut would be even.

How To Cut Metal-Plastic Pipes

Some experts, answering the question of how to cut metal-plastic pipes at home, suggest using various home-made devices or tools that were not originally designed to perform the task in question. We strongly discourage following such advice. To cut pipes, you must use exclusively specialized tools. over, its price is low.

For cutting metal-plastic products, you need technical scissors. This tool often comes with brawling kits. These scissors are equipped with blades specially designed for cutting structures from the material in question. Their handle is ergonomic. Therefore, it is very convenient to use them.

You need a tent to place the cut and begin the task. No special skills are required for slicing. Anyone can handle this procedure. But if you have NEVER done this, practice on any unnecessary or defective pipe first.

You can use an ordinary pencil to mark the cutting site. The mark can also be made with an angle grinder. In the latter case, it is important NOT to make deep marks. Since this way you have every chance of seriously damaging the pipe structure. Be sure to use safety goggles when cutting. They will protect your eyes from small particles of metal-plastic.

How and what to cut metal-plastic pipes at home

In the process of installing or repairing pipelines made of metal-plastic pipes, it becomes necessary to cut pipes. This is a task that needs to be done as correctly as possible. Inaccurate cuts can ruin products.

There is a misconception that only metal pipes can be cut, and metal-plastic products need to be changed entirely. This is completely NOT true. Metal-plastic products are easy to cut. The main thing is to use high-quality tools and to carry out each stage of the task as accurately as possible. In this article you will learn how to cut metal-plastic pipes.

Preparatory stage

First you need to collect everything you need to solve the problem.

The list of tools includes:

  • Calibrator;
  • Pipe bender;
  • Adjustable wrench;
  • Any fabric.

As you know, metal pipes include a plastic layer and an aluminum mat. They are solidly soldered by means of laser welding. The frame is an aluminum tube. The core of the product is quite smooth.

However, experts still recommend cleaning the surface of the structure from possible irregularities before starting cutting.

To clean pipe products, you must use a coupling. The process of cleaning the surface of the product itself Takes a little time.

Technical nuances

The most convenient for cutting are pipes with a diameter of five to thirty centimeters. If you need to cut a larger piece, it is better Seek help from a qualified technician.

You can cut metal-plastic products with various tools. The procedure is very similar to cutting PVC products. For the operation, we can use a hacksaw or a knife with teeth. But it is best, as we said above, to use a specialized tool.

If you decide to cut off the pipe for dismantling purposes and you are NOT going to use it in the future, let’s say you can perform the operation with almost any tool. For all other purposes, cutting must be done with special scissors. Only they will allow you to make a high-precision cut.

During cutting, it is necessary to take into account Not only the deformation rate of the product under the influence of temperature conditions, but also from physical factors. Too much force during the operation can lead to cracks in the product. Despite the fact that metal-plastic is more flexible than metal, it is subject to various deformations.

Purge or Flush the pipe after cutting. Choose a cleaning method based on the purpose of the structure. If this is not done, a small amount of small particles may remain inside the pipes, which in the near future may become a prerequisite for a breakdown of the pipeline or devices connected to it. The electronic cutting method is NOT too well suited for working with reinforced plastic. It is best to use a hand tool to trim this material. For example, a ribbed blade lubricated with machine oil.

Tools for cutting metal-plastic pipes

In the process of cutting pipes, the following tools come in handy:

It is important for the master to determine in advance what he will use to cut metal-plastic pipes. The most important tool on the list is scissors. Everything else is required for Special Preparatory Work.

It is not necessary to exert much effort during the cutting process. It is enough just to fully control every movement. If you do not pay enough attention to control, you can easily cut off the excess part.

If during the cutting process it is necessary to bend the product, it is not recommended to do it by hand. So you can easily spoil the aluminum layer, which is inside. It is better to take a professional pipe bender and perform the operation with it.

Using inappropriate tools when working on one area can affect the entire network as a whole, leading to high repair costs.

Before proceeding directly to cutting, it is necessary to very clearly measure the part where the unit will be divided. For this, a tape measure or ruler is used, as well as a bright marker. A faded pencil can simply not be seen, especially if there is not enough lighting in the room. The mark can be made with a knife, left scratches.

During operation, pieces of plastic and aluminum can fly in different directions. Therefore, you must use protective equipment in the form of glasses and special clothing.

Hacksaw

First. It’s a hacksaw. Arriving with a pipe and a hacksaw on some object, they do this.

Straight edges are obtained. And when the pipe is inserted into the pipe, this gum bites from the edge, so the plumbers have to do an additional operation, namely, chamfering. This is done either with a knife, respectively, or the pipe simply rubs against the concrete, and a chamfer is obtained.

Cutting technique

Self-cutting can be done with products with a diameter of 5 to 30 cm.So, if the product does NOT fall within these limits, it is best to turn to professionals.

When carrying out any such manipulations, it is important to remember the basic rules:

  • Reinforced plastic products are very sensitive to temperature, so some problems may arise in hot or cold weather. The material shrinks and expands easily, making it difficult to determine the true dimensions.
  • Metal-plastic pipes, like polypropylene pipes, can be cut using any means at hand. But in order to avoid various negative consequences, it is best to do this with Special tools.
  • A special self-sharpening knife is an excellent tool. But if it is planned to carry out work to replace one section with another, it is better to abandon the tool in favor of scissors.
  • The material is quite fragile. Applying too much force is fraught with cracks or specific deformations. The permissible load can be seen in the product passport, which was issued at the time of installation of the water supply.
  • The type of cutting directly depends on the proportion of metal and plastic in the product. If there is more metal, then there should be as little friction as possible when cutting. Otherwise, a large proportion of plastic means more work with high friction.
  • Before starting work, it is imperative to make sure that no water or gas flows through the pipe. You need to turn off all the taps and wait a little.
  • After completion of work, you need to properly clean the inside of debris, which can lead to clogging or break specialized equipment.

The use of electronic cutting tools is not considered reasonable as the material specifications are not designed for. Can be handled manually.

High-quality cutting of polypropylene pipes

Due to the growing popularity and prevalence of polypropylene pipes (propylene polymer) used to equip water supply systems and other communications, the demand for a specialized tool that makes it easier to work with the material has increased significantly.

As a rule, straight lengths are sold on the market (up to 12.0 m), although polypropylene pipes in coils are often found, which are used for the installation of underfloor heating systems.

Tool types

There are several types of pipe cutters for metal-plastic. The tool may differ in principle of operation, cost, cut quality.

Classification by torch type

The cutting mechanism of the tool can also differ in the way it is applied to the pipe. According to this criterion, pipe cutters for metal-plastic are divided into:

  • Roller. Equipped with one or more movable rollers fixed on a C-shaped curved platform. The number of rollers usually determines the maximum pipe thickness that can be worked. The metal-plastic pipe is clamped into the holder, the mark of the future cut is aligned with the cutting element, after which the tool begins to rotate around the pipe axis. With each turn, the cutter approaches the pipe, gradually deepening into its surface and dividing it into two parts. The blade does not press with force on the pipe wall, but cuts through it gradually, so the cut is smoother and cleaner. A small amount of burrs can occur when the cut is jerked with little movement of the part. expensive models with telescopic travel are free from this disadvantage.
  • Guillotine type. Such a tool eliminates the possibility of deformation of the cut area due to the uniform application of the load. The blade of the device can be lowered by rotating the handle, or in more expensive models, after pressing the trigger. The guillotine version effectively works with pipes with a cross section of up to 100 mm.
  • Ratchet. They act like scissors. Designed for pipes with a cross section of up to 100 mm. Work item. Sharp steel blade. The pipe fits into a semicircular recess on the tool body. After fixing and marking, the handles are closed and cutting is carried out. Ratchet Cutters are simple in design and affordable. Also suitable for cutting polypropylene products. The main disadvantage of such tools. The likelihood of flattening of the pipe ends (additional processing with a calibrator will be required) and the impossibility of guaranteeing perfect perpendicularity of the cut.
  • With clamp latch. Improved model of the roller pipe cutter, equipped with special devices for tight fixation of the pipe.

How to cut metal-plastic pipes

Reinforced-plastic pipes have a number of advantages over their competitors. They are much lighter than metal and much more resistant to oxidation than copper. They are easy to replace and easily shaped. You can create piping of any shape. Well, the main advantage is cost. It is much lower than that of copper pipes. And the quality is about the same.

During operation, it may be necessary to cut pipes. For this, a special tool is used, which is designed to work with such a material. To improve the effectiveness of the procedure, it is recommended to properly prepare the pipe and tools before work. Consider the main features of metal-plastic pipes and how to cut them.

Cutting methods

There are several basic cutting methods, which directly depend on the tool used. First of all, you can cut products:

  • Knife for efficient cutting of reinforced plastic pipes. The knife in this case should be used self-sharpening.
  • A hacksaw for metal. The simplest method, which, however, will require a lot of effort and time from the performer. In addition, the edges can be torn.
  • Scissors.
  • Pipe cutter.

With some tools, the edges of the cut are quite uneven, and particles of material can subsequently cause the floor to clog. The best way is to use Special scissors, which cut evenly, do not leave ragged edges. These scissors can cut objects up to 40 mm in diameter.

For larger diameter products, it is better to choose a Pipe Cutter. Pipe cutters are telescopic and ratchet. The first type is based on the operation of a special roller that rolls along the entire circumference. The second type is more like scissors, since it uses a lever system with two handles.

It is believed that if it is necessary to replace such pipes, the entire pipeline must be changed. But this opinion is wrong. Products are easy to cut and change in parts without harm to the general water supply or heating system. The following is how to properly cut metal-plastic pipes.

Preparing the pipe and the necessary tools

As tools, the same cutting device, measuring tapes, adjustable wrenches, seals and some other things are used. All this should be in an accessible place at the time of work.

Sometimes it is required to clean out the outer part of the reinforced covering to simplify the cutting process in the next step. For stripping, a clutch with blades is used, which allows you to get a perfectly smooth cut and get rid of the polymer layer. This is necessary for welding work, which will most likely be carried out during the installation of the pipeline.
