Advantage Analysis
High production efficiency: ERW steel pipe adopts high frequency resistance welding technology. That can achieve rapid continuous welding process, thus greatly improving production efficiency.
Low cost: Due to high production efficiency and simplified process, its production cost is relatively low.
Saving materials: In the production process of this pipe, the utilization rate of raw materials is high, which can effectively save materials.
High dimensional accuracy: It uses rolled steel strip/coil with uniform and accurate overall size as raw material. So the dimensional accuracy is high and the wall thickness is uniform.
Good surface quality: good surface quality, short weld and high pressure.
Wide range of application: This steel pipe is widely used in water supply and drainage engineering, oil and gas engineering and other fields. It can also be used as piling pipe, bridge, dock, road, building structure pipe and so on.
Operation Steps Of ERW Steel Pipe
Raw material preparation: The factory will use the hot rolled wide strip steel coil as raw material for pre-treatment, such as unwinding, straightening, end cutting, end welding, cutting edge, etc.
Forming: The pre-treated steel strip enters the forming machine for forming, mainly using continuous roll forming method or row roll forming method.
Welding: At the same time of forming, high-frequency resistance welding technology is used for welding to form a continuous weld.
Weld treatment: After welding, the internal and external welding thorns (welding nodules) at the weld are removed by the welding thorn removal equipment.
Sizing and cutting: After sizing, the steel pipe is sawed to a fixed length.
Finishing processing: straightening, flat end, hydraulic test, inspection, wire and coating (or galvanizing) and other finishing processing processes.
Packaging factory: The final packaging and factory.
