Carbon Steel Pipe

Description

Carbon Steel Pipe produced by using Electric resistance welding (ERW) process where metal parts in contact are permanently joined by heating them with an electric current, melting the metal at the joint to create a straight welding line. The electric current can be supplied to electrodes that also apply clamping pressure, or may be induced by an external magnetic field. The electric resistance welding process can be further classified by the geometry of the weld and the method of applying pressure to the joint: spot welding, seam welding, flash welding, projection welding, for example. Some factors influencing heat or welding temperatures are the proportions of the workpieces, the metal coating or the lack of coating, the electrode materials, electrode geometry, electrode pressing force, electrical current and length of welding time. Small pools of molten metal are formed at the point of most electrical resistance (the connecting or "faying" surfaces) as an electrical current is passed through the metal. In general, the range of thickness is usually not more than 8 mm. and outer diameter ½ - 8 inches.
The customers able to customize the length of its specific pipe. Moreover, they can identify the steel surfaces according to external coating and colors, for example, red oxide, coated varnish, hot-dip galvanizing, etc.
Production capacity of black carbon round and square pipe
