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...
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...
