EAGLE™ ASTM A270 Stainless Steel Tubing (40″ Precut)
Sanitary ASTM A270 Tubing for Food, Beverage and Dairy Process Lines (40″ Precut)
- Bright Annealed Polished Sanitary Tubing ASTM A270
- Available in 316L Stainless Steel
- Stamped with Heat Lot Number
- Manufactured in accordance with 3A Standards for sanitary line process requirements
Polished stainless steel sanitary tubing is precisely manufactured in accordance with ASTM A270 standards. Moreover, our tubing stands out as it is meticulously crafted from cold-rolled stainless steel strip. This strip is chosen with utmost care, and its chemical elements expertly controlled to optimize weldability. Furthermore, the weld bead undergoes extensive cold-working until it achieves a fully finished state, resulting in an almost imperceptible longitudinal weld.
The manufacturing process culminates in a crucial step: bright annealing. This step is meticulously conducted within a controlled atmosphere to ensure the preservation of maximum structural integrity. This meticulous process guarantees not only a polished exterior but also unwavering performance and durability.
