ASTM A270 Stainless Sanitary Tubing
A270 Sanitary Tubing: Specifications, Grades, and Applications
A270 Sanitary Tubing is designed for sanitary applications and is available in ferritic, austenitic, seamless, or cold-worked varieties. Teda Steel supplies ASTM A270 Tp316L, Tp304, and other material-grade sanitary tubing to meet various needs.
Key Features of A270 Sanitary Tubing
- Material Grades: The most commonly used grade is ASTM A270 Tp304, with Tp316L for high-corrosion environments. Tp304 is preferred in less corrosive applications.
- Dimensions and Tolerances: A270 tubing has wall thickness tolerances under 12.5%, with diameters ranging from 1.24mm to 3.81mm, ideal for small-diameter applications.
- Construction Types: Tubing is available in seamless and welded forms, with the seamless type meeting strict standards prohibiting welded joints. Welded pipes have no filler metals to ensure compliance.
