ASTM A312 Pipe
Products description：
Stainless steel pipe is primarily used in piping systems for the transport of fluids or gases. Stainless steel pipe resists oxidation, making it a low-maintenance solution that is suitable for high temperature and chemical applications. Because it is easily cleaned and sanitized, stainless steel pipe is also desired for applications involving food, beverages and pharmaceutical applications.
