FeedbackDifference Between Seamless and Welded/ERW Pipes

Seamless steel pipe can be formed one time in the rolling process. Welded steel pipe is manufacturing with steel strip or steel plate, through bending and different welding processes. Performance and Usage Seamless steel pipe has better pressure capacity, strength is higher than ERW welded steel pipe. So it is widely applied in high pressure erw welding 300mm diameter steel pipe How does ERW pipe welding work?How does ERW pipe welding work?During the ERW pipe welding processes, the electric current will make the heat when flow through the contact surface of the welding area. It will heat the 2 edges of the steel to a point that the edges can form a bond. Meanwhile with the combined pressure, the edge of the pipe billet steel melted and extruded together.Differences between ERW Steel Pipe and HFW Steel Pipe What is the difference between ERW and HFW steel pipe?What is the difference between ERW and HFW steel pipe?Differences between ERW and HFW Steel Pipe. ERW pipe manufacturing process includes HFW. ERW have low, medium, high frequency welding processes, and HFW is specially for high-frequency electric resistance welding. The differences between ERW and HFW steel pipe, is EFW is a type of ERW process for ordinary and thin-wall thickness steel pipes.Differences between ERW Steel Pipe and HFW Steel Pipe

Differences Between SAW and ERW Pipe Winsteel Group

There are many kinds of pipes in the carbon steel pipe. You will see the weld steel pipe and seamless steel pipe. And in the welded steel pipe, you will find different methods of forming processes, such as erw, LSAW, SSAW. So first, lets see what the differences between saw pipes and erw pipe are.Differences between ERW Steel Pipe and HFW Steel PipeHigh frequency welding (HFW) steel pipe is that ERW pipe produced with a welding current frequency equal to or greater than 70 kHZ. Through high-frequency current welding resistance, the heat generated in the contact objects, so the objected surface are heated to the plastic state, then with or without forging to achieve a combination of steels.ERW Steel Pipe - SHINESTAR STEEL GROUP CO., LTD.(1) welded pipe from steel plate welding into the round pipe, divided into high frequency resistance welded pipe (ERW welded pipe), straight seam arc welding pipe (LSAW), spiral welded pipe.Electrical engineering with SC, can be used as water gas pipe can also be used as threading pipe
