The detail value of hydro-static is as below :
Shell testing 1.5times of nominal pressure : by hydro-static ( water ) with 2.4Mpa
High pressure closure testing 1.1time of nominal pressure: by hydro-static ( water ) with 1.76Mpa
The counter-flange sets also included along with valve as per user’s requirement. It’s more convenient for user that user can install the valve to pipeline using the counter-flanges.
