You can order and buy a wide range of metal products ( pipes, valves, ducts, wire, bar, mesh , etc.).

Metal pipes can be of the following types: round, square, rectangular, oval, flat oval. To determine which pipes are required, the size must be clear: for round pipes – diameter, for square or rectangular – the length of the side in millimeters, and the wall thickness must be known for all types of pipes.

In terms of the outer diameter of the wall thickness, metal pipes are divided into :

– thick-walled metal pipes;

– thin-walled metal pipes.

Field of application of metal sewing pipes.

Due to the variety of shapes and sizes, metal pipes are used almost everywhere; they can be used as heating pipes, as ventilation pipes and even as elements of metal structures for heavy industry.

Metal pipes can be used in the construction and installation of fences, playgrounds, roofs and terraces – in these cases, the lightweight structure doesn’t create additional pressure on the support and allows you to increase the size of construction sites.

Also, due to the properties of metal sewing pipes , they can be processed in many different ways: cutting, bending, painting, welding, used in aggressive environments and more.

Advantages of metal sewing pipes:

  • Large range of applications;
  • Good corrosion protection;
  • Resistance to external influences;
  • Long service life;

Composition of metal seam tubes:

The basis of the production of the pipes is carbon steel (low or high alloy).

The alloying of the steel is achieved by adding some impurities to the steel, which allows to improve its characteristics. Low-alloy steel contains about 2.5% impurities, high-alloy – about 10%.

Alloying steel with chromium or manganese allows to improve the technical characteristics of the products. The cost of these pipes is slightly higher, but the pipes are more durable, have a longer service life and have better welding results. At the same time, the resistance to adverse factors is increased by additional measures: finished steel is covered with polymer compositions and bitumen.
