Sanitary ASTM A270 Tubing for Food, Beverage and Dairy Process Lines

 

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.

• material: 304
• yield strength (PSI): 30,000
• tensile strength (PSI): 75,000
Working Pressure = ¼ of Burst Pressure, these calculate from -20°F to 100°F.
