Product Description

Product Description

ASTM A270 Tp316L Sanitary Stainless Steel Seamless Tube Pipe Bright Surface

ASTM A270 standard covers the specifications for sanitary seamless and welded tubing. Typically made from austenitic stainless steel such as SS304 or SS316L  with common sizes include 1/2 inch to several inches in diameter, which offers excellent corrosion resistance and sanitation properties. They usually have a smooth interior finish, often polished to a 20 Ra or better, which minimizes the risk of contamination and biofilm growth. It's recognized for meeting hygienic and sanitary requirements, making it suitable for applications in high-purity environments.
