ASTM A270 TP304 Sanitary Stainless Steel Tube
Product Overview
Hygienic Austenitic Stainless Steel Tubing for High-Purity Process Systems
ASTM A270 TP304 Sanitary Stainless Steel Tube is designed for hygienic process systems where internal cleanliness, corrosion resistance and surface quality are critical. Manufactured from austenitic stainless steel, the tubing is supplied with controlled internal and external finishes to support cleanability and product purity in food, beverage, dairy, pharmaceutical and biotechnology applications.
Depending on project requirements, the tube can be mechanically polished, bright annealed or electropolished. Surface roughness can be controlled to meet specified Ra values, helping reduce product retention and supporting effective CIP (Clean-in-Place) and SIP (Sterilize-in-Place) procedures. These characteristics make ASTM A270 tubing suitable for sanitary process lines that require reliable hygiene performance.
