Material introduction of high pressure seamless steel pipe

High-pressure seamless pipes refer to a type of seamless pipe that can withstand both high temperatures and high pressures. Any pipe produced using the seamless pipe process and capable of enduring such conditions is classified as a high-pressure seamless pipe. The difference lies in the material used, which determines the pipe's suitability for different environments. Below is an introduction to the materials commonly used in high-pressure seamless steel pipes.

GB5310-2008 Seamless Steel Pipe
This standard covers high-pressure boiler tubes, which are primarily used in power station boilers that require resistance to both high pressure and high temperature. Typical materials used for these pipes include 15CrMoG, 20G, and 12Cr1MoVG. These materials ensure the pipes can withstand extreme conditions in boiler systems.

GB3087-2008 Seamless Steel Pipe
Though classified under low and medium pressure boiler seamless steel pipes, this pipe can also be considered a high-pressure seamless pipe in a broader sense. It is mainly used for transporting low and medium pressure fluids in industrial and domestic boilers. The common materials used for these pipes are No. 10 and No. 20 steel.

GB6479-2000 Seamless Steel Pipe
This type of pipe is specifically designed for use in high-pressure fertilizer equipment, transporting high-pressure fluids within such machinery. The materials commonly used are 16Mn, 12Cr2Mo, 20, and 12CrMo, which provide the strength and durability needed for high-pressure applications.

GB3093-1986 Seamless Steel Pipe
These high-pressure seamless pipes are mainly used in diesel engines, particularly for high-pressure injection lines. The material used for this purpose is 20A steel, which ensures reliability under the high-pressure conditions in diesel engines.

From the various high-pressure seamless pipes mentioned, it is clear that these pipes are widely used in boilers, chemical equipment, and engines. Since each type of high-pressure seamless pipe is made from different materials to suit specific applications, it is important to select the right pipe for the appropriate environment to avoid impacting the service life of the machinery.
