The petrochemical industry involves corrosive fluids such as acids, alkalis, and salts. Stainless steel pipes have the characteristics of corrosion resistance and oxidation resistance. In the petrochemical industry, stainless steel pipes are mainly used in pipeline transportation systems, including high-pressure furnace pipes, piping, petroleum cracking pipes, Fluid transportation pipes, heat exchange pipes, etc. Stainless steel pipes also play an important role in equipment manufacturing, oil production, refining and other industries in the petrochemical industry. Stainless steel is required to have good performance in wet and acid service. Industries mainly use stainless steel seamless pipes. , specifications include: 304, 321, 316, 316L, 347, 317L, etc., the outer diameter is around ￠18-￠610, and the wall thickness is around 6mm-50mm (generally choose medium and low pressure pipeline specifications above φ159mm).
For example:
Heat-resistant stainless steel pipes are mainly used for heat exchange and fluid transportation.
Duplex stainless steel pipes have the characteristics of high strength, stress resistance, corrosion resistance, economy, etc., and are mainly used in the chemical industry, fertilizer heat exchanger and fluid pipe markets.
Stainless steel bushings, stainless steel non-magnetic drill collars for oilfield drilling production, high resistance to CO, CO2 and Cl-corrosion super ferritic stainless steel Cr13, Cr25 and other oil casings.
