API 5L Psl1 Psl2 ASTM A53 Welded Hot Dipped Carbon Steel ERW Steel Pipe For Oil & Gas
ERW steel pipes and tube are available in various qualities, wall thicknesses, and diameters of the finished pipes.
Hot dip galvanized ERW steel pipe look a little rough compared to the electro-galvanized, silvery white, look prone process waterlines and a few drops of tumor is more obvious, especially in the one end of the workpiece. Hot dip galvanized zinc layer than a few times of the electro-galvanized thick corrosion protection is several times that of the electro-galvanized.
