    Dissimilar weld joint for high temperature applications

    Thank you for the response. Design is as per ASME, Boilers and Pressure Vessels Code, Section III Div, 1 subsection NC (Class 2). Testing and inspection conforms to ASME, Boilers and Pressure Vessels Code, Section VIII. Hydrostatic pressure testing and pneumatic pressure testing as per UG-99 and...

    Dissimilar weld joint for high temperature applications

    I want to design a process vessel as per the sketch attached. The top end of the vessel conforms to SS316L, electropolihsed and the bottom part conforms to Inconel 600 and Hastelloy X 194. The location of the dissimilar weld joint is also shown. The maximum temperature that the weld joint will...

    ASME code for welding of SS316L and Inconel 600 and SS316L and Hastelloy X 194

    Thank you XL83NL, The location at which SS316L monolith machined from the inside will be welded to Inconel 600 seamless pipe would see a slightly higher temperature than ambient although the SS316L portion will be cooled by copper coil wound around it with inlet water temperature of 14 oC at a...

    ASME code for welding of SS316L and Inconel 600 and SS316L and Hastelloy X 194

    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...

    ASME B31.3: Clarification on inspection and testing for low pressure low temperature piping

    Sirs, Thank you very much for the responses. I would like to slightly modify the specifications of the argon gas. Keeping all the experimental conditions same, if we assume that argon has 0.005% probability of containing Cd vapours (chemically hazardous) and <0.001% probability of radioactive...

    ASME B31.3: Clarification on inspection and testing for low pressure low temperature piping

    I would like to design an argon gas recirculation system where the fluid temperature will not go beyond 40 oC. Maximum pressure (Design pressure) of the piping system will not be more than 1000 mm of water column. The piping system comprises of 1/2-inch, 1-inch, 1-1/2-inch and 2-inch seamless...
