In life, a person sometimes faces the problem of cutting parts. How to solve this problem? We will answer this question in this article. Today, there are many ways to cut pipes (both with your own hands and by contacting a specialist), but let's start in order. As we understand Installation of utilities, today pipe cutting is an activity that will not be difficult to complete.

What processes are alternatives?

Plasma cutting competes with all profiling technologies in the processing of sheet and plate metal materials. This is due to the wide range of applications in terms of thickness and flexibility. It will most often compete with flame cutting and laser cutting technologies, but has some significant advantages over both.

Plasma cutting and flame cutting

Plasma cutting imparts less heat to the profile, resulting in a significantly reduced heat-affected area on the cut edges.

Plasma cutting and laser cutting

Plasma cutting can cut the same and greater thickness of material than laser cut. What should be considered when choosing and defining plasma cutting.
  • Plasma cutting cannot cut as thick material as flame cutting.
  • Plasma cutting has a cleaner cutting edge.
  • Both can have comparable zones exposed to heat.
Plasma cutting creates a heat-affected zone on the cut edge of the profile, this is due to the fact that the cutting mechanism is the melting of the material of the material.

Pipe cutting can be done with a grinder.

Cutting methods

We list the tools with which cutting is performed:

  • Hacksaw for metal (hacksaw);
  • Roller pipe cutter;
  • Bulgarian (machine with an abrasive disc);
  • Gas-flame machines (acetylene-oxygen, kerosene-oxygen and gasoline-oxygen cutters);
  • Laser machines.
  • Let's talk about the features of each cutting method.

    The level of energy used in plasma cutting is significantly lower than flame cutting due to its cutting speed and therefore the area exposed to heat is smaller with plasma cutting. This is especially true for very thin sheet materials. Plasma cutting can be used for plate, sheet and lattice or mesh materials, however, sandwich-shaped materials such as honeycomb, which have voids throughout their thickness, cannot be cut. This is due to the destruction of the plasma beam when the layers are cut and the voids are exposed to the cutting head.

    hacksaw

    The hacksaw machine consists of a sliding frame, a handle with a rod, a tension screw and a hacksaw blade. The canvas is fixed in the frame with a screw and a rod. The part is fixed in the vise of the workbench and cutting is performed. It is important during operation to ensure that the hacksaw blade does not overheat.

    Plasma cutting is applicable to a wide range of metal cutting situations, from flat plate materials to 3D sections. Plasma cutting profiles in most cases are in themselves a margin for further processing. Purchasing plasma cutting profiles can provide an improvement by reducing heat-affected areas and distortion on profiles that currently burn out. Reduction of costs and difficulties associated with further processing, such as processing the hard edge of the flame cutting profile and combating distortion and stress due to heat input during the cutting process.

    Pipe cutting with a laser is smoother than with other tools.

    • cutting pipes with a hacksaw is a long and laborious process, especially if it is pipe cutting large diameter;
    • the edge of the cut pipe will have irregularities, which will not allow the part to be pressed tightly during welding. To solve this problem, you need to clean the surface with a file.

With a plasma cutting system, the workpiece can be cut using a plasma arc. The plasma jet is compressed in a copper nozzle.

    Roller pipe cutter

    Cutting with a roller pipe cutter is a more productive way. It consists of cutting rollers (their number depends on the design features of the tool), a body, a sliding holder and an adjusting screw. Cutting is carried out by rocking up / down and gradually pressing the rollers with a screw.

    Pipe Plasma Cutting Application

    This compression of energy is so great that the workpiece melts very quickly. The material to be processed and its thickness determine the energy input. In the high-end area, a material thickness of around 64mm can be easily achieved with our plasma cutting system.

    Basic Plasma Cutting Equipment

    At the request of the customer, we are happy to produce individual plasma cutting, but we also used equipment in the range. Plasma cutting portal cutting system driven from both sides by linear motors on racks.

    Operation of the plasma cutting system

    Automatic, laser, waterjet, marking and plasma cutting, including the use of pipes and conical cutters. Efficient extraction of exhaust gases at the point of cut prevents fume contamination from contamination.

    The disadvantages of this tool include the same Fast as that of a hacksaw: the duration and laboriousness of the process.

    Abrasive Disc Machine

    A grinder is perhaps the most common and most traumatic tool for cutting and grinding metal. Cutting pipes with a grinder is carried out due to the operation of an electric motor that rotates the abrasive disc. The danger of work lies in the frequent non-compliance with safety regulations. Let's get acquainted with the main points of the rules:

    The new pipe cutters almost completely eliminate waste or chips, meaning that less manual shredding is required to prepare pipes before welding. Plasma pipe cutting machines can make straight, 90-degree, facing, serrated, and branch cuts, as well as several other types of cuts, some of which were not possible with previous equipment.

    The pneumatic pipe control system allows operators to securely assemble and disassemble pipes of various diameters and lengths to ensure maximum productivity. In the 1960s, the company developed equipment that allowed farmers in the wealthy and growing regions of southern California to remove sand, silt, gravel, algae, and other contaminants from plumbing. The production of these systems begins with the production of steel or stainless steel containers with a diameter of three to four feet, with holes for connecting pipes that will move water through the filter block.

  • The grinder must be equipped with a protective cover.
  • Under no circumstances should you work without goggles or a protective mask.
  • The direction of movement of the angle grinder must coincide with the direction of rotation of the abrasive disc, otherwise an uncontrolled exit of the disc from the slot may occur.
  • It is impossible to cut stone, concrete or other materials around for cutting metal. Each type of disk must be used for its intended purpose.
  • The pipe must be securely fixed in a vise.
  • A Bulgarian should be a person who knows how to work on it and no one else.

    Flame torches

    There are two types of gas burners. Some machines for manual cutting, others for semi-automatic cutting of tubes. cutting manual machine is not an easy job. It is very difficult to make the edge at the pipe cut even and smooth. Cutting on a semi-automatic machine is considered to be of better quality.

    A good amount of perforated tubes must be cut before they can be soldered and painted. The company recently determined that its plasma cutting system was not delivering the required productivity or quality. This had two major drawbacks. First, there was no easy way assemble and disassemble tubes in and out of the machine, which caused a production bottleneck. Second, he left good amount burrs that had to be ground manually before starting welding processes.

    In addition, the machine experienced more and more mechanical and electrical problems, which caused high costs for Maintenance and downtime. The machines offered several advantages over previous equipment. In addition, an efficient exhaust system captures smoke at the cutoff point, so the workshop is not polluted - complying with California County Air Quality Management regulations. Some cuts, such as cuts in pipes that would have taken four hours with the old system, are now completed in as little as five minutes.

    Laser machines

    Laser cutting machines are modern automated systems, which use advanced pipe cutting technology and metal structures. They are distinguished by high quality of work performance and a wide range of tasks performed in one operation. Such tasks include cutting, drilling, edging, milling.

    Possible parameters of pipes for processing:

    • maximum external diameter- 150 mm;
    • maximum length - 6.5 m;
    • maximum wall thickness: black steel - 6.4 mm, stainless steel - 5 mm, aluminum - 4 mm;
    • the maximum length of the finished pipe is 3 m.
