Working Pressures Calculator

Soft – Working Pressures

Max outside Diameter (mm)
Min wall thickness (mm)
Output pressure – Bar
Output pressure – PSI
max working pressure at 65 C
max working pressure at 110 C
max working pressure at 150 C
max working pressure at 175 C
max working pressure at 200 C

Half Hard – Working Pressures

Max outside Diameter (mm)
Min wall thickness (mm)
Output pressure – Bar
Output pressure – PSI
max working pressure at 65 C

Note – if tubes in the HH condition are annealed eg during brazing or hard soldering, the stress value for annealed condition should be used for calculating working pressures.
