Re: [MW:25575] Hydrostatic leak testing

Dear Prem,

The provision to do priming & painting is only optional ( "may be ").
So vendor cannot argue that it is mandatory to be painted !! You may
tell such paintings may mask pin-holes or any other seepages during
test. An amicable agreement to be made.

Also all welds should be exposed means - NOT to be hidden (like
undergrond joints) or to make insulation etc. doesnt mean couldn't be
painted..

Hope this info helps you little.

Regards,
Kumar.
