ASTM A358 standard applies to straight or spiral welded stainless steel pipes, which are usually used in industrial applications at high or low temperatures or in special environments.
SA358 TP 309S stainless steel welded pipe has excellent high temperature resistance, and its heat resistance temperature can reach above 1000℃, so it can work for a long time in high temperature environment. It has good corrosion resistance and can resist corrosion from most organic acids, inorganic acids and salt solutions.
ASTM A358 Grade 309S EFW Pipe is widely used in petrochemical industry, such as oil refining equipment, chemical equipment, oil heating furnace, etc.
