Table A-1. Temperature range
for different tank seal material.
For Tri-Clamps, the maximum pressure is 16 bar for 1.5 in. (37.5 mm) and
2 in. (50 mm) housing; and 10 bar for 3 in. (75 mm) and 4 in. (100 mm)
housing. The final rating depends on the clamp and gasket you are using.
Tri-Clamp is available for the Standard Temperature and Pressure seal.

Rating
Flange strength calculations are made with the following conditions:
• For 316L SST:
• For Alloy C-276:
Calculations show that the following applies.
