How to prevent and solve the porosity problem of the steel pipe seam
Welded steel pipe is divided into two kinds according to its welding seam shape-straight seam steel pipe and spiral steel pipe. Steel pipe seam porosity affects not only the density of pipe welds, resulting pipeline leak, and will become a point of corrosion-induced, severely reducing weld streng...Read more -
Pipeline corrosion resistance to hydrogen sulfide
Hydrogen sulfide corrosion resistant pipeline steel mainly used to manufacture and transport sour gas pipeline. With the improvement of the delivery pressure and reduce the gas from the viewpoint of the cost of desulfurization, sometimes without desulfurization of the gas pipeline circumstances, ...Read more -
Advantages of Using Galvanized Steel Pipe and Fittings
