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. We can produce by your customed requirements 100%
brand newly produced or supply you the stock pipes for your urgent
needs. Besides ERW black steel pipe, we can also do other carbon
steel pipes, like seamless pipe, LSAW pipe, spiral welded pipe, and
galvanized pipe, stainless steel tubes. We welcome your any inquiry
and shall response to you very soon.
