Standard of hot expanded steel pipe

• International Standards

1. ASTM standard: The American Society for Testing and Materials (ASTM) has formulated a series of standards for hot expanded steel pipe, including ASTM A106, ASTM A53, ASTM A335 and so on. These standards specify the chemical composition, mechanical properties, dimensional accuracy and surface quality of hot expanded steel pipe and other indicators.
2. DIN standard: German national standardisation organisation (DIN) has also formulated many standards for hot expanded steel pipes, such as DIN17175, DIN2391-2, etc. These standards specify the chemical composition, mechanical properties, dimensional accuracy and surface quality of hot expanded steel pipes. These standards specify the production process, performance indicators and dimensional accuracy of hot expanded steel pipe requirements. 3.
3. JIS standard: Japan Industrial Standards Organisation (JIS) also has the corresponding hot expanded steel pipe standards, such as JIS G3458, JIS G3462 and so on. These standards specify the chemical composition, mechanical properties, dimensional accuracy and surface quality of hot expanded steel pipe indicators.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

• Chinese standard

1. GB/T standard: "Steel Pipe GB/T8163-2018" formulated by the National Standardisation Administration Committee (SAC) is the national standard for hot expanded steel pipe. The standard specifies the chemical composition, mechanical properties, dimensions and allowable deviations and other indicators of the hot-expanded steel pipe, which is applicable to the transmission pipeline and machinery manufacturing in the petroleum, petrochemical, electric power, natural gas and other industrial fields.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

2. Petroleum steel pipe standards: The petroleum industry has high requirements for the standard of hot expanded steel pipe, there are some independent oilfield enterprise standards, such as SY/T0413, SY/T0508 and so on. These standards put forward higher requirements than the national standards for the quality, precision, size and surface quality of hot expanded steel pipe.
