Production
The temperature of hot deformation is initially 1100 °C and at the end of — 900 °C. the Finished product is cooled in air. Precision production pipe to produce high and normal precision. Made the following types of pipe: seamless hot-rolled pipe, cold-rolled and warm pipe General purpose electric-welded pipe. They demanded for industrial structures and construction of pipelines. The manufacture of pipes is regulated by the following GOST 30 245−2003, 10 706−76, 10 705−80, 380−94, 13 663−86, 1050−88, 8639−82, 8642−68, 8645−68 etc. Each of the standards specifies the individual characteristics of the product, for example, of a tube with a certain section.
Welding
Performed after heating to 250−400°C With the final heat treatment. The fastening elements of structures and pipes arc carried out by manual method or by automatic welding. the final heat treatment is recommended for stress relief during welding. Welded pipe is produced of the following types: profile with a square cross-section, welded round, oval and rectangular cross-section,
Application
Pipe brand 20X13 in great demand in metallurgy and petrochemical engineering, because the quality of the alloy ensure the production of products with long-life performance under load at temperatures up to 900 °C. above 900 °C at the surface leads to the formation of scale. Water and gas in industrial and household systems, such a tube is used very widely for supplying liquid or gas, installation of heating systems.
Assortment
The pipe can be with different thread types: with sliced and rolled straight thread or without it. It all depends on the wishes of the buyer. The assortment and the size of the pipes comply with the requirements of GOST 3262−75. Supply pipes of different lengths. 4 — 12 m — dimensional length, the dimensional tube length, the length of which is estimated in the range of dimensional. For each cut made allowance for 5 mm, the longitudinal deflection of pipes shall not exceed 10 mm the entire length.
