Dear All,
Your advice required on the below matter.
In one of our project we deign and constructed the PLR (Pig Launcher & Receiver) as per ASME SEC VIII DIV 1, The PLR is already hydro tested. Now our client required to make one new nozzle the PLR, Since the PLR is already hydro tested so my question is what are things we have to taken care while alteration (New Nozzle) on vessel.
I have checked in ASME SEC VIII DIV 1 but code is silent on the Alteration and all.
Equipment details:-

Design Pressure 18bar
Operating Pressure 10 bar
So please suggest me on this matter.
Thanks in Advance
