I wish to fabricate a 10" vessel using seamless 10" pipe of Inconel 600 that will be welded at the bottom of 11" SS316L cylindrical rod. The pipe portion will be operated at 1000 K and SS316L portion will be attached to an enclosure from the top through a gasket type flange. It will have a cooling provision by winding copper coil around SS316L rod through which process water at 10 [sup]o[/sup]C will flow at 1.5 kg/cm[sup]2[/sup][sup][/sup] pressure. The welded portion will also experience sufficient stress at this temperature. What is the recommended filler wire to be used for such applications and what are the various tests that the weld has to pass through before the vessel is tested at high temperature. The vessel will experience at least 2 bar pressure at 1000 K, so what is the recommended hydro static pressure test that it should be subjected to at room temperature.
For a similar application, I wish to weld a 10" seamless pipe of Hastelloy X 194 with 11" SS316L cylindrical rod. This vessel will be operated at 1200 K, and the maximum vacuum that it should be subjected to is 0.01 mbar or less. What is the recommended filler wire to be used for welding of Hastelloy X 194 pipe and SS316L rod?
Which ASME code should I look into for getting an answer, and what are the hydrostatic pressure test requirements for qualifying the pressure vessels?
Thank you,
Sincerely,
