Hello guys!
Recently I specified a flexible metal hose for N2 service that is conected a reciprocating compresor nozzle.
Operation condition:
Pressure: 440 psig
Temperature: 40°C
When I bought it a more experience engineer, said that we have a standard that said that is not recomended use...
During my work last week, I was asked about the possibility to change the hydrostatic leak test for pneumatic leak test.
The line condition is:
Fluid: Steam
Temperature: 650°F
Design Pressure: 275 Psig
At first the test was specified in accor with ASME B31.3 Hydrostatic leak test
345.4.2 Test...
