To put you more in the picture its a modification with a series of pressure reducing...
I read it as when fabricated in the workshop you do your fabrication pressure tests. Then when connected on board you are testing the full installation assembly which means all joints connected on board. Which is the norm.
Thanks for the responce but if I have derated from the original 200 bar WP. Go through a correct welding procedure and hydrostatic test to cover the 60 bar all would be ok?
I understand what you are saying its still acting as a pressure vessel.
I have done it before on a 200 bar 12 litre...
I have a 50 litre seamless gas cylinder with a 200 bar working pressure. I wish to cut a hole approx 50mm in the side midway along the cylinder and weld in a weld type fitting giving me a thread to connect too. I want to convert this to a buffer tank with a max pressure of 60 bar the gas medium...
