- Allowable working pressures are calculated from an S value of 20,000psi for ASTM A269 Tubing (at -20 to 100°F (-28 to 37°C))
- According to the requirements of ASME 3 (Process piping Code)
- For Weld Tubing Pressure
- ASME 1(Power Piping Code)
- for double welded tubing: working pressure x 85
- for single welded tubing: working pressure x 80
- Safety Factor: 75: 1, Ultimate tensile strength of 75,000psi
- For gas service, select a tube wall thickness outside of the shaded
