Cracking steel pipe 219x17mm st.15X5M-U GOST 550-75

Cracking steel pipe 219x17mm st.15X5M-U GOST 550-75 is a seamless hot-formed steel pipe. Their main area of ​​application is the chemical industry and cracking (high-temperature processing of oil into smaller fractions). And it is these conditions of their use that determine the increased requirements for plasticity and strength of products and, as a result, the reduction of pressure losses in the process of transporting the working medium.

Hot-rolled cracked tubes are seamless, have an optimal metal structure and other parameters and mechanical properties that provide a longer service life, and also have a fracture coefficient that is five times lower than their cold-rolled counterparts.

The range of outer diameters of pipes is from 25 to 630 mm, wall thickness - from 2 to 30 mm.

Cracked pipe (GOST 550-75) is mainly produced by hot pressing of cast billets. The raw material is carbon and alloy steel, steel grade 15X5M is considered optimal, which is strictly regulated by the specified GOST. Recently, an analogue of 15X5M steel, R5 steel, has also been widely used.

Products are subjected to heat treatment, hydraulic control, as well as a number of tests in accordance with regulatory documents. Cracking pipe 15X5M or its equivalent is shipped with a full indication of its chemical and mechanical parameters.
