Re: [MW:11522] NDT on Pipe line for Natural gas

Dear Sir

1. Before pressuring the lines, each weld joint shall be
cleaned by wire brush or power brush to free it from rust and any
other foreign matter.So at any way don't allow painting or priming
before hydrotesting.

2. If you are going to UT or MPI (NDT) -- You will not get proper
Intrpretuation result and smooth movement of probe is also not
possible.So don't allow painting.

3. If your NDT method is RT then you can continue painting.(After hydro)
