Application of alloy steel pipes in petrochemical industry
Alloy steel pipes are often used in key parts of oil refining and chemical plants, such as various furnace tubes of oil refining plants, including atmospheric and vacuum furnace tubes, coking furnace tubes, and hydrofining furnace tubes; process piping of oil refining plants, including atmospheric and vacuum furnace tubes, Pipes for high-temperature parts such as oil transfer lines of coking plants; steam pipes above medium pressure in various plants, etc.
Therefore, the petrochemical industry has very high performance requirements for the alloy steel pipes in the production equipment. Whether it is infrastructure or maintenance, the types and specifications of alloy steel pipes required are complex. The commonly used alloy steel pipes are mainly steel pipes with a Cr element content of more than 1% and less than 13%. The commonly used materials are 15CrMo, 12Cr1MoV, P11, P22, 10CrMo910, Cr5Mo, Cr9Mo, etc., and the commonly used outer diameter ranges from 18mm to 610mm. There are 2 to 5, and even 10 to 14 different wall thicknesses for each diameter. Therefore, there are about 800 types and specifications (material, outer diameter x wall thickness) that may be used. The purchase of alloy steel pipes often becomes a key factor affecting the overall construction, inspection and maintenance of refining and chemical infrastructure projects.
