    Parametrization of weldings in pipelines in service

    Being responsible for parametrizing weldings of fittings to pipelines where there is natural gas flowing in it, I have to calculate the heat input for the beads being made during welding the fitnesses to the pipeline. The heat input HI= V.I/v shouldn´t overpass the maximum value allowable, to...

    Heat input for welding in pipelines in service

    In the DEP 32.38.60.10 from Shell there is an appendix which allow us to calculate the maximum heat input that can be generated in welding pipeline in service for the butterings and for the first and second fillet weld. What about the other beads after these? Welding a fitting in a pipeline...

    Heat input for welding in pipelines in service

    What shell be the maximum heat input for welding fittings to pipelines in service? Is it the ones specified in the qualification welding procedure?

    Heat input in wedling pipelines

    Anyone knows what shell be the maximum heat input that can be produced in welding fittings to pipelines under pressure (natural gas flowing in the pipeline)? I have the Welding procedure records for those welding productions, where I can calculate the heat inputs based on the I, V and welding...
