The wide range of application and specifications of ERW pipe

The process of electric resistance welded steel pipe(ERW pipe) is rolled up with a cold-rolled steel or hot rolled steel sheet. The welding method on the device is using a straight seam welding method. All pipes which is obtained from this process called ERW. Why do we call them like this? Because there is a straight line in all of the welded steel pipes and the title derives from that.


ERW steel pipes and tubes are available in various qualities, wall thicknesses, and diameters of pipes and this pipe is widely used and there is also some differences in the production process. Some pipes are produced into scaffolding pipes and others are made into fluid conduit. As the wire threading pipe, guardrail tube or stent , etc. , we can almost everywhere see those pipes in our family or public facilities. The steel pipe prices is vary from the application and purposes of them. For example, the price of welded fluid conduit is about 4300 yuan per ton, while the common pipe is cheaper than that about 4200 yuan per ton. Of course, the price is not always stay the same, we should take into consideration of the factors that affect the price fluctuations of welded steel pipe market.
