Outer Diameter 114.3mm - 610mm ( 4 "- 24 " ) Water ERW Black Steel Pipe
ERW (Electric Resistance Welded), HFI (High Frequency Induction), HFW (High-Frequency Welding)
Compared with processing technique of ERW pipe, the processing technique of seamless steel pipe is much simpler. There are two entirely different types of processing technique: cold-drawing and hot rolling. Compared with hot rolling, the technological process of cold-drawing is more complicated. Moreover, in the appearance, cold-drawn seamless stainless-steel pipe is shorter than hot-rolled one and the wall thickness of cold-drawn seamless stainless-steel pipe is generally smaller than the wall thickness of hot-rolled one. What’s more, the technological process of hot rolling needs high temperature which reduces the resistance of deformation so that a big deflection is achieved. Generally speaking, the technological processing of ERW pipe and seamless steel pipe are quite different, due to the different appearance.
We can provide ERW black steel pipes with the quality strictly in acc. to ASTM A53, API 5L, EN10219, EN10217 etc. Our ERW black steel pipe with premium quality, we can accept TPI inspection by your designation.
