Pipes made of copper nowadays widely used for gas and water supply systems, heating systems, for the production of oil pipes, compressed air pipes, a wide range of household appliances, automobile and mechanical engineering. The distinctive features of the copper pipes may include: strength, thermal conductivity, durability, formability, and corrosion resistance aggressive chemical compounds.
In the industrial use of the following types of copper tube:

  • Copper pipe, thick-walled and thin-walled;
  • Rectangular and square;
  • capillary;
  • waveguide;
  • usual round profile.
    Enough wide circulation in industrial applications received thick-walled copper tube. It is used where it is necessary to withstand the high pressure of liquids or gases. For example, it is possible to use in gas pipelines, oil pipelines, a fluid supply system at a pressure in heat exchangers.
    Called thick-walled pipe, wherein the ratio of external to internal diameter ranges from 6 to 12.5. In accordance with GOST 617 thick-walled copper pipe can have the following geometric dimensions:
    - An external diameter of from 3 mm to 360 mm;
    - Wall thickness - 0.8 mm to 10 mm;
    - The length of the copper thick-walled pipe is manufactured in lengths or coils.
    If we talk about the production of copper thick-walled pipes, then there are two main ways of production: Seamless (cold-worked) and welded. In the process of cold-copper thick-walled tube is made by drawing or drawing, cold rolling, pressing. Welded thick-walled obtained by welding longitudinally coiled blanks.
