Galvanized steel tubes welded steel pipe: also known as welded pipe, steel sheet or strip is bent after molding, then made by welding. Press the seam into the form of the Longitudinal and spiral welded pipe. By end-use can be divided into general pipe, galvanized pipe, Oxygen pipe, wire casing, metric pipe, roller tube, deep well pump tube, automotive, transformer tubes, welded thin-walled tubes, welded shaped tubes and spiral welded pipe . With welded steel pipe technology to enhance and improve the processing is simple, and now instead of part of seamless welded pipe, welded steel pipe is capable of producing 219mm (8 inches) or more. Galvanized pipe: To improve the corrosion resistance of steel pipe, steel pipe for general (clarinet) galvanized. Galvanized steel hot galvanized and electrical steel zinc are two kinds of thickness galvanized galvanized, electro-galvanized costs. With welded steel pipes and processing technology to improve to improve convenience, and now instead of part of seamless welded pipe, welded steel pipe is capable of producing 219mm (8 inches) or more. Galvanized pipe: To improve the corrosion resistance of steel pipe, steel pipe for general (clarinet) galvanized. Galvanized steel hot galvanized and electrical steel zinc two, thickness galvanized hot dip galvanized, electro-galvanized low cost.
