Influence of Heat Treatment on ERW Welded Pipe
Update: 2017-12-13 View (s): 1587 Keywords :erw welded pipe, heat treatment. Resistance Welding (ERW) is a low-cost, high-efficiency pipe manufacturing technology whereby various technically produced steel pipelines are called ERW pipe. ERW pipe is made of steel plate or strip after the high-frequency resistance after welding and resistance welded steel pipe, which has a longitudinal weld pipe How are steel bands heated in ERW pipes?In the case of conventional ERW pipes, the outside and inside corner edges of the steel band heat and melt preferentially, resulting in non-uniform heating in the sheet thickness direction. In contrast, with Mighty SeamTM, the material is heated and melted homogeneously in the wall-thickness direction.See all results for this questionHeat Treatment for ERW Welded Pipes - United SteelJan 19, 2018 · Date: 2018-03-21 View: 955 Tag: Heat Treatment for ERW Welded Pipes.
