ASTM A269 TP304 Stainless seamless Steel Tubes

ASTM A269 covers seamless and welded austenitic stainless steel pipes, focusing on general corrosive environments without high pressure and high temperature (such as chemical equipment and water treatment systems).
The carbon content of tp304 stainless steel seamless pipe is ≤0.08%, which reduces the risk of intergranular corrosion. It is suitable for conventional corrosive media in fertilizer, pharmaceutical, petrochemical and other industries. The long-term operating temperature is ≤300℃, covering scenes such as reactor jackets, cooling circulation systems, and liquid delivery pipelines.
The production cost of ASTM A269 tp304 stainless steel cold-rolled pipe is 10% lower than that of A312 TP304 stainless steel seamless pipe, which is suitable for small and medium-sized pressure vessels.

Product Case

A petrochemical enterprise uses A269 TP304 tubes (φ600×8mm) as seawater cooling pipes for crude oil pretreatment equipment. It has been running for 5 years without leakage, and the total cost is 28% lower than that of A312.
