LASW WELDED STEEL PIPE, LASW Welded Steel Tube, with the production method of longitudinal welded arc welding. ERW Welded Steel Pipe is produced by electric resistance welding method, from raw material of hot rolled or cold rolled steel plate, steel coils. There is a straight weld seam on both inside and outside surface of the tube body, so that we call it welded steel tube. The inside weld
China Spiral Galvanized Pipe Suppliers, Manufacturers Range of simulation parameters:vertical pipe:pipe diameter D=lOmm, pipe length L=660mm;There are three kinds of vertical t-welded steel tubes:diameter D=10mm, ratio of curvature diameter of t-welded steel tubes to spiral diameter changes are Dc/D= 15,20,25, spiral pitch Pt=20mm, pipe length L=503mm, L=660mm, L=817MM, respectively.Mass flow rate G=200~400Kg/(m'2·s), heat flux
Causes and preventive measures of the porosity of LASW welded pipe:(1) welding groove not clean, rust, scale, and impurity water, etc.For example, the steel plates before welding of LASW and after milling edge of steel plates are stored for several days, they are affected by damp, the edges of the plates are polluted, and they are not well
