Tube Information

Proper tubing is essential to the performance of a tubing system. Consider a system's pressure, flow, temperature, environment and compatibility with the process fluids when choosing the tubing material, size and wall thickness.

Wall Thickness

The wall thickness selection should be based on the operating pressure, temperature and shock conditions. Fully annealed tubing is recommended. Stainless Steel Tubing having a hardness of less than Rockwell Rb90 should be used.

Cold Drawn Tube A213 and A271
O.D 1-1/2" and under Over 20% Under 0%

Cold Drawn Tube A269
O.D Less than 1/2" Over and Under 15%
1/2" to less than 8" Over and Under 10%

Cold Drawn Pipe A312 and A376
O.D All size Under 12.5%

Seamless Stainless Steel Tubes

Grades in regular production to ASTM A269 : TP304, TP304L, TP316, TP316L, TP321, TP347.
Grades in regular production to ASTM A213 : As stated for A269 plus TP304H, TP316H, TP321H, TP347H, TP310S.
Other grades are available on application.
