[MW:7203] Re: effect of longer holding time during hydrotest

Dear Asad,

The time required for hydrotesting of any equipment is mostly based on
the complexity of its construction. You can say that its the time
required for a sign of leakage or seepage to take visual effect. So
the more complex the equipment is, the longer should the time be
extended.
Furthermore, if you are having a sufficiently weak member in the
system, the exposure time should be enough to allow that member to
leak or crack etc.
For equipment sound enough, no impact on the physical properties & in
a nutshell, the time should be up to the satisfaction of the
inspector.

Regards,

Muhammad Ali
