ASTM A312 Welded Stainless Steel Pipes

Specific requirements of Welded Stainless Steel Pipe

We can provide ASTM A312 seamless, welded stainless steel pipes. Welded pipes shall be made using an automatic welding process with no addition of filler metal during the welding process. Welded pipes of NPS 14 and smaller shall have a single longitudinal weld. Welded pipes of a size larger than NPS 14 shall have a single longitudinal weld or shall be produced by forming and welding two longitudinal sections of flat stock according to clients' requirements.

 

Advantages of Welded Stainless Steel Pipe

ASTM A312 stainless steel pipe contain a lot of chromium elements. Chromium element can form a dense oxide film on the surface of the pipe, prevent the contact between steel pipes and corrosive media. Steel pipes that contains molybdenum elements, such as 316 series, perform well in resisting pitting and crevice corrosion. In additions, This steel pipe ensures the safety and reliability of pipeline in high-temperature environments due to stable structure and excellent high-temperature mechanical properties.
