Types of Steel Piping Materials Used in Oil & Gas

The petroleum and petrochemical industry is the pillar industry of the national economy, and it occupies a pivotal position in the national economy. In the past 20 years, the production technology level of stainless steel pipes, whether seamless or welded, has been greatly improved. The stainless steel pipes produced by some domestic manufacturers have reached a level that can completely replace imported products, realizing the localization of steel pipes. Stainless steel gas pipes have the advantages of high tensile strength, high ductility and toughness, low thermal expansion coefficient, strong corrosion resistance, strong wear resistance, long service life, light weight and recyclability.

In the petroleum and petrochemical industry, stainless steel pipes are mainly used in pipeline transportation systems, including high-pressure furnace pipes, piping, oil cracking pipes, fluid transportation pipes, heat exchange pipes, etc. Stainless steel is required to perform well in wet and acid service conditions.
