For self-assembly of systems, the presence of a pipe cutter is the main condition. It helps to quickly and efficiently cut pipes of a given length. The cuts are smooth and neat, which greatly facilitates the work of plumbers and installers.

You can use a metal hacksaw to cut such elements. But the result is of poor quality: there is no cutting accuracy, there are numerous burrs at the end. It is necessary to additionally do the alignment of the edges, using specialized tools for these purposes. In addition, a hacksaw cannot always be used, since there is a special material that is not suitable for these procedures. A precise 90 degree cut is achieved by using a pipe cutter exclusively.
When carrying out perpendicular cutting with equipment, the ends of the workpieces are smooth and of high quality. His performance indicator far exceeds the capabilities of a hacksaw. The devices are widely used in the construction of new facilities, dismantling outdated heating and water supply systems, and replacing damaged areas. They cope with their function “perfectly”.
It is considered the best tool when working in close proximity to explosive objects or where there is no possibility of connecting to the electrical network.
An overview of the designs shows that they all have design differences, but they have two principles of operation:
View | Description |
---|---|
Orbital | The movement of the cutting part occurs in a circle. The fixed part grasps the tool and turns. Requires a lot of free space to operate the machine. The furrow gradually deepens until the cut is completely finished. Used for cutting special material in the installed pipeline. |
Stationary | A special machine is assumed. The device is stationary, and only the part rotates. Copes with significant product diameters. The method is used when producing a large volume of material. |
The devices differ in the following parameters:
For industrial purposes, devices with a non-mechanical principle of operation are used:
The equipment body is made of the following materials:
In order to resist corrosion, individual elements of the housing can be coated with a protective layer based on chromium or a special paint composition (powder). The steel structure is assembled from individual elements, which are also subjected to such a procedure as hardening. This ensures significant stability of the loaded and rubbing against each other nodes. Chromium-plated components are not afraid of moisture, have a good indicator of wear resistance, are resistant to corrosion, and have an excellent appearance. Cutting elements can be steel, tool or made of special grade steel (alloyed).
The weight and size of the selected device depends on where the tool will be used and what the maximum diameter of the elements will have to be cut. Scissors for 42 mm products have an average weight of 300 to 500 grams, and their length is from 250 to 350 mm. As for electrical devices, their weight and dimensions depend on the engine and mechanisms for fixing the fragments of the products.
After reviewing the data given in the product passport, the buyer can reveal information regarding the minimum and maximum diameter of structures with which the selected unit is able to cope. The pre-installed ratchet mechanism will help to cope with thin copper walls, however, the diameter of the working raw material should not exceed the 42 mm mark. Electric and pneumatic models work with diameters up to 1500 mm, roller - 50 - 100 mm, incisal - up to 100 mm.
The best manufacturers produce popular models of the following types:
The tools differ in the principle of operation, and therefore they are divided into the following types:
The criteria for choosing a device for cutting pipes are different for everyone. Which one is better to buy depends on many factors. If you review the rating of quality products, you may be surprised at the variety of equipment for copper, aluminum, steel and other types of pipes. It is also important how much the product costs.
