Scissors for cutting plastic pipes: types and features of choice

In the modern world there are several types of tools designed for cutting plastic pipes. Among them, the main place is occupied by special scissors. Devices designed for cutting polypropylene pipes are divided into two main types: guillotines and scissors.

Special features

Choose a tool is based on the diameter.

  • Consider the guillotine: This device is a cutting tool with long handles. These pens are covered with a rough substance to make it comfortable to hold.
  • Scissors. This tool has a special lever ratchet design. The blade has hardened stainless steel.Such scissors can easily cut polypropylene pipes whose diameter is 60 - 350 mm.

In order to get a completely flat cut with a blade, this product is covered with a layer of Teflon. Thanks to him, notches appear in place of the cut.

All scissors designed for cutting pipes from metal-plastic have many differences.

All of them are equipped with approximately the same design, consisting of several elements.

  • Stainless steel blade. Thanks to him, high-quality cutting is achieved.
  • The handle with rubber inserts, designed to ensure that the tool does not slip out of hands.
  • Special supports. They guarantee a cut at an angle of exactly 90 degrees.
  • Rake blade It is serrated, making the cutting process much easier.
  • A device or button that controls the edges to open when necessary.
  • Retainer. It is necessary for the product to be kept in the closed state.

Device of adaptation and the principle of its work

This tool is manual and is used during the plumbing installation works in the process of supplying the house with water and creating heating systems.Blanks are cut before the start of welding.

Plumbing scissors provide the greatest effort that focuses on the cutting edge. Scissors for cutting plastic pipes are a complex lever design, so that the handle can be planted with one hand without much effort.

The device should be selected depending on how large the diameter of the pipe to be cut, focusing on the design features of scissors. For example, there are scissors for pipes, very similar to ordinary household ones, although slightly modified. They are designed for a diameter of 0.5, 1 and 2 inches. One end of the instrument is considered carrying. One side of the scissors is equipped with a comfortable handle, and the other - with a profile in the shape of the letter “V”.

In order to make the cut, the scissors is brought close to the pipe with the bottom of the device. Due to this, it is possible to cut the polymer pipe into equal parts, which differ in diameters, and the force exerted on the handle will remain minimal. The design features of the scissors make it easy to replace the cutting blades if the need arises.

In today's market, the most prominent manufacturers of polypropylene pipe trimmers are manufacturers:

  • General;
  • Reed;
  • Rothenberger.

Varieties of scissors

Below we consider the types of the cutting device.

Precision scissors

This type of tool is equipped with blades and ratchet mechanism. There are jagged plates on the blades. These scissors are used to cut the pipe into small sections with diameters from 3 mm to 4.2 cm. This is the simplest product that is very convenient to handle.

In order to cut polypropylene pipes such scissors, you do not have to put any effort. However, this choice has its drawbacks.

The main disadvantage is that while using the device blade will constantly move to the side, which contributes to the curved tear of the pipe.

Roller pipe cutter

Such a device is of two kinds. The first is telescopic, the second is equipped with a ratchet mechanism. In order to cut the plastic pipes PND with such scissors, you need to drive a special roller through them. You can cut pipes of different diameters, including large ones, 50-75 mm. The positive side of this device is that it allows you to create absolutely smooth edges of the cut, but the speed of execution will be low.

In telescopic variations of the instrument, cutting is ensured by rotating the cutting edge around the polypropylene tube.

Cordless scissors

Cordless scissors are automatic, professional and equipped with a small electric motor.

With such scissors you can very quickly cut the pipe (literally in 5 seconds). As you may have guessed, the advantage of choosing such a device is a very high speed of work. But, like all tools, it also has negative sides.

The disadvantage is that such scissors can cut pipes whose diameter is not more than 4 cm.

Nuances during the work

Due to the fact that the blade of scissors is equipped with a special rail with fine teeth, the operator does not have to put a lot of effort during operation. Scissors are designed so that they can work with only one hand, the other can hold the pipe or perform other actions.

If you damage the pipe during cross-cutting, the damaged area will have to be removed, otherwise the docking will not be tight.

While cutting the pipe should follow a specific algorithm works.

  • Before starting work, the cut point should be noted with a felt-tip pen.
  • Tool blades are placed on top of the mark. In order to more conveniently place the tool on the pipe, you can pre-make a small incision on it.
  • Insert into the pipe should be done very carefully, without exerting much pressure on the scissors handle.
  • Do not move your hand during work. Otherwise, the scissors may slip to the side, and the cutting process will have to be repeated anew.
  • The blade base should be positioned exactly along the surface of the plastic pipe.

Tips on choosing

Before you choose and purchase such a device, you need to ensure that the quality is fully consistent with the proposed price.

If you plan to use the device for minor plumbing repairs, then buying expensive scissors is not advisable. However, do not forget that the cheapest options for scissors are very poor quality. Often their blades are not covered by a special substance, and they also do not have sufficient sharpness.

If you chose an automatic instrument, you need to make surethat scissors easily cope with large diameter pipes.

The so-called precision scissors have always been famous for their versatility and low price. Such devices have always been reliable and quite comfortable in use.

The price of scissors for threading PP-pipes depends on the size of their diameter. The overwhelming number of devices designed to use the physical strength of the worker. When performing large amounts of work can appear chronic fatigue.

If the device is intended for serial repair work, it is advisable to use automatic pipe cutters. Guillotine version is designed for large diameter pipes.

However, not all buyers know the types of pipes being cut. Below we consider them in more detail.

  • Pipes that are used to create a warm floor, as well as for cold water systems, are labeled "PN 10". The maximum temperature that these pipes can withstand is 45 degrees.
  • Pipes designed to bring cold water to a building are marked “PN 16”. These parts create wiring that easily cope with high blood pressure.
  • Products for both cold and hot water are labeled "PN 20". The highest temperature that these pipes can carry reaches 80 degrees.
  • There are pipes equipped with aluminum foil, with a maximum tolerated temperature of 95 degrees. They are labeled as "PN 25". These products are used to create central heating and hot water systems.

However, in addition to pipes, there are quite a large number of additional propylene parts on the market. And also there are products of the combined type. This option has brass inserts and is called "American." With this part you can make the transition from a plastic pipe to the metal elements of the plumbing system.
