Custom Reliable Transportation Of Hazardous Materials Seamless Fluid Petrochemical Steel Pipe

Stainless steel piping is widely used in Petro and chemical processing plants due to its corrosion resistance and durability. It is used to transport various chemicals, gasses, and liquids, including corrosive and high-temperature substances.

In chemical processing plants, stainless steel petrochemical piping is used for its resistance to corrosion and chemical reactions. Stainless steel petrochemical pipe can withstand exposure to harsh chemicals and maintain its structural integrity, making it a reliable choice for transporting hazardous materials.

Petroleum and chemical industries are generally divided into industrial chains based on raw materials, that is, commonly referred to as the coal chemical industry, salt chemical industry, petrochemical industry, biochemical industry, and phosphorus chemical industry. The petrochemical industry chain is usually an industry chain that produces oil products, basic organic chemicals, fine chemicals, and synthetic materials from oil and natural gas.

The demand for the use of stainless steel in the petrochemical industry can be roughly divided into four aspects, namely corrosion resistance, low-temperature resistance, high-temperature resistance, and high strength. General corrosion environment and clean environment commonly used 304, 316 materials; 2205 and 2507 materials are commonly used in pitting and crevice corrosion environments. Low-temperature environments commonly use materials for 304, 304L; The common material for the high-temperature environment is 304H; 316 materials are commonly used in alkali stress corrosion environments; Carbon dioxide corrosion environment commonly used 304L, 316L materials; 321H and 347H materials are commonly used in high-temperature hydrogen and hydrogen sulfide environments. In addition, the application environment of stainless steel materials in LNG plants, ethylene plants, PDH plants, coal gasification plants, and oil refining plants is briefly reviewed.

Finally from the petrochemical stainless steel pipe demand situation, compared with martensitic stainless steel corrosion resistance and ferrite stainless steel brittle too large lack of electricity, austenitic stainless steel has better corrosion resistance, welding performance, low-temperature performance, and non-magnetic, so become a widely used in petrochemical stainless steel. Due to the limitations of composition control, heat treatment, and welding, ferritic stainless steel pipe is currently less used in the petrochemical industry, but with the application of smelting and heat treatment equipment technology will gradually increase.
