HI! I am new here but i'm hoping somebody would help me about this, We have AMINE SERVICE LINE and it has RT100%(only butt joints), PWHT 100%(all joints excl. Seal welding) and attachment (pipe support directly welded on pipe), HARDNESS100%(butt joint only) and MT 100% (all joints excl. Seal welding). may i know the sequence for its test requirements? i think it is much suitable to conduct first the RT, second PWHT, and then HARDNESS and finally MT.

Thanks in Advance
