Welded pipe fitting is a steel plate

　　Welded pipe fitting is a steel plate or strip after the steel coil after welding made of.3000lbs High Pressure Forged Carbon Steel Threaded Weld Outlet production process is simple, high production efficiency, variety specifications, equipment, less capital, but generally less than the strength of seamless steel pipe. Since the 1930s, with the rapid development of high-quality strip rolling production and the progress of welding and inspection technology, the quality of welded seam has been improved continuously, the variety specifications of welded steel pipe are increasing day by day, and more and more fields have replaced the non- Seam steel pipe. Welded pipe in accordance with the form of weld is divided into longitudinal and spiral welded pipe.
