Dear Rahul,
We understand that verywell what is your intention .
Hydrostatic pressure resting to ensure the Strength & Integrity of the piping systems.tightness test is a part of hydro test not equal to hydrotest.
Regarding Code difference ,you know well.....there are different standards infact principle is same for both.
Generally we have to follow ASME code unless it is mentioned particularly.
Thankyou
Suresh

Hello All,
I have one question regarding scope of Hydrostatic pressure testing of
piping systems.
As per ASME B31.3, Hydrostatic pressure testing of the piping systems is
defined as Hydrostatic leak test ie to check each piping system to
ensure tightness.
The PED (97/23/EC) guidelines & EN 13480 pressure piping code ask for
PROOF TESTING, ie by Hydrostatic testing, of the piping systems to check
the Strength & Integrity of the piping systems.
Why there is such difference between the approach/aspect of Hydrostatic
testing ?
If in 31.3, Hydrostatic pressure testing is only defined for check the
tightness ? how can one satisfy the PROOF TEST requirement of PED for
ASME B31.3
Your kind replies will be highly appreciated.
Kind regards
Rahul
