A Guide To Selecting Threaded Stainless Steel Pipes

In the field of threaded stainless steel pipes, each country has its own unique standard system. China follows the GB/T12771-2008 standard, which has strict regulations on various technical indicators of threaded pipes and is suitable for the transportation of various media. The United States uses ASTM and ASME series standards, such as ASTM A312, which perform well in high-temperature and high-pressure environments. European standards are mainly based on the DIN and EN series, such as DIN17455, which are also suitable for a wide range of applications. Japan follows JIS standards, such as JIS G3459, which are particularly suitable for high-temperature and high-pressure environments. When purchasing threaded stainless steel pipes, multiple dimensions such as material, size, surface treatment, brand, and price should be considered comprehensively.

It is recommended to use 316L stainless steel to cope with most environments, while ensuring that the thread type matches the connecting fittings. The surface treatment should be smooth and undamaged to extend service life. In terms of brand, choose manufacturers with high reputation and good service.
