Hi,
We did use piping for dosing water containing chlorine inside the cooling Tower. For that we used HDPE Piping with Fibre Glass Lining from outside (throughout the piping). Minor Leakage was there at flanged connection with Valves as Valve Flanges were of CI. We could not able to tight the...
While calculating Hydrotest Pressure follow the followings:
As per Pressure Temp ratings specified in B16.5, you will get the pressure at Atm Temp 38degreeC. That will be the design pressure for the flange. You take 1.5 times of it as Max allowable hydrotest pressure for the line.
If you are...
