technical characteristic

Grade 20X13 is a stainless heat-resistant alloy. It is used in the production of low-loaded parts which work at temperatures of 900-1000°C. Its composition includes chromium-12-14%, nickel, manganese and silicon 0.6% each, carbon-0.16 - 0.25%, thousandths of a percent of sulfur and phosphorus, the rest - iron.

Production

The hot deformation temperature is 1100 °C at the beginning and 900 °C at the end. The finished product is cooled in air. In terms of manufacturing precision, the pipe is produced in increased and normal precision. The following types of pipes are produced: seamless hot-rolled pipe, cold-rolled and thermally deformed general purpose pipe, electric-welded pipe. They are in demand for industrial structures and pipeline construction. Manufacturing 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 and others. Each of their standards stipulates individual characteristics of the product, for example, from a pipe with a certain cross-section.

Welding

Performed after heating to 250-400 ° C with a final heat treatment. Bonding of structural elements and pipes is carried out by manual arc welding or by automatic welding. final heat treatment is recommended to relieve stresses during welding. Electric-welded pipe produced by the following types: square cross-section profile, round seam, oval and rectangular cross-section,

Application

Tube grade 20X13 is in demand in metallurgy and petrochemical engineering, because the quality of the alloy provide the production of long term operation under load at temperatures up to 900 ° C. Above 900 °C scale starts to form on the surface. In water and gas industrial and domestic systems such pipe is used very widely for the supply of liquid or gas, installation of heating systems.

Range

Pipes may be with different types of threads: with or without a cut and rolled cylindrical thread. It all depends on the wishes of the buyer. The assortment and size of the pipes meet the requirements of GOST 3262-75. The pipes are supplied in various lengths. 4 - 12 m is measured length, the pipe is multiple of measured length. An allowance of 5 mm is made for each cut, longitudinal deviation of tubes shall not exceed 10 mm for the whole length.
