What are the applicable scenarios for different standards of stainless steel pipes

The following are the applicable scenarios for different standards of stainless steel pipes:

GB standard (Chinese national standard)

GB/T 14976 "Fluid Transport Stainless Steel Seamless Pipes": Suitable for pipeline systems in industries such as petroleum, chemical engineering, medical care, food processing, and light industry, for the transportation of fluids, such as the transportation of chemical raw materials, the transportation of food and beverage fluids, and the gas and liquid transportation pipelines in hospitals.

GB/T 14975 "Structural Stainless Steel Seamless Pipes": Often used in fields such as construction structures and mechanical structures, like the supporting structures of buildings, the steel components of bridges, the frames and supports in mechanical manufacturing, etc.

GB/T 41317-2022 "Stainless Steel Flexible Pipes for Gas Appliance Connections": Specifically suitable for the connection of gas appliances and gas pipelines, including various gas stoves, gas water heaters, gas meters, etc.

ASTM standard (specifications of the American Society for Testing and Materials)

ASTM A213 "Ferritic and Austenitic Alloy Steel Seamless Pipes for Boilers and Heat Exchangers": Widely used in power and chemical industries for boilers and heat exchanger equipment, for the transportation of high-temperature and high-pressure steam, hot water, or other heat exchange media.

ASTM A269 "General Purpose Austenitic Stainless Steel Seamless Pipes and Welded Pipes": Can be used for various general purposes, such as food processing equipment, ordinary chemical equipment, railings and handrails in the field of building decoration, etc., and is also often used for the manufacturing of mechanical components with certain requirements for corrosion resistance and formability.

JIS standard (specifications of the Japan Industrial Standards Association)

JIS G3459 "Stainless Steel Pipes for Pipelines": Widely used in fields such as building water supply and drainage, air conditioning systems, and gas pipelines in Japan and some Asian countries, and also applicable to occasions where there are certain requirements for corrosion resistance in general industrial pipelines.

JIS G3463 "Stainless Steel Pipes for Boilers and Heat Exchangers": Mainly used for boilers and heat exchangers, similar to ASTM A213, but more commonly used in the relevant industries in Japan, and is a commonly used standard for the manufacturing of boilers and heat exchangers in Japan.

DIN standard (German standard specifications)

DIN EN 10357: Applicable to the food, beverage, and chemical industries, such as transportation pipelines for food and beverage, storage and transportation pipelines for chemical raw materials, etc., to ensure that the pipes do not corrode or contaminate when in contact with food, beverages, or chemical substances for a long time.

In mechanical manufacturing and the automotive industry: Germany's mechanical manufacturing and automotive industries are very developed. Stainless steel pipes of the DIN standard are used in these fields to manufacture mechanical parts, automotive parts, etc., such as the exhaust pipes of automobiles, hydraulic system pipelines, etc., with strict requirements for the size accuracy, mechanical properties, and corrosion resistance of the pipes.

ASME standard (specifications of the American Society of Mechanical Engineers)

In the petrochemical and power industries: Stainless steel pipes of the ASME standard are often used in high-temperature, high-pressure, and highly corrosive medium transportation pipelines in petrochemical plants, as well as important equipment and pipeline systems in the power industry, such as power station boilers, steam pipelines, etc. These occasions have extremely high requirements for the safety and reliability of the pipelines.

In pressure vessel manufacturing: The ASME specification has detailed regulations on the materials, manufacturing processes, and inspection of stainless steel pipes for pressure vessels, ensuring the safe operation of pressure vessels under various working conditions, and is widely used in pressure vessel manufacturing in the petrochemical, chemical, and pharmaceutical industries.
