Manufacturer for Industrial Steel Pipe - ERW SSAW welded steel pipe – Hongmao Detail:
Product introduction
Welded steel pipe: Also known as welded pipe, it is made from strips of steel cut into narrow strips of steel, which are then moulded into tubes. A special welder then welds the seam together. External weld is polished. According to different welding methods, it can be divided into arc welding pipe, high frequency or low frequency resistance welding pipe, gas welding pipe, furnace welding pipe, bandi pipe, etc. According to the shape of the weld can be divided into straight seam welding pipe and spiral welding pipe. Electric welded steel tubes are used in oil drilling, machinery and manufacturing industries. Furnace welded pipe can be used as water gas pipe, straight welded pipe for high pressure oil and gas transmission; Spiral welded pipe is used for oil and gas transportation, pipe pile, bridge pier and so on. Compared with seamless steel tube, welded steel tube has lower cost and higher production efficiency.
