Production process of ERW pipe

2018-06-12 16:07:26   Comment:0 Hits:

  ERW Pipe, also known as welded pipe, is made of steel plate or strip rolled after welding and made of steel pipe, generally 6 meters in length. The ERW Pipe has simple production process, high production efficiency, many varieties and less investment in equipment, but the general strength is lower than that of ERW Pipe.

  The longitudinal ASTM A53 GR B Carbon Steel ERW Pipe has the advantages of simple production process, high production efficiency, low cost and rapid development. The strength of a ERW Pipe is generally higher than that of a straight ERW Pipe. It can produce a larger pipe with a narrow blank, and the same width of the blank can be used to produce a pipe with different diameters. However, compared with the straight ERW Pipe of the same length, the weld length is increased by 30~100% and the production speed is low.

  Large diameter or thicker ERW Pipe are usually made directly from steel billets, while small ERW Pipe can only be welded directly through steel strips. And then, after a simple polishing, the wire can be made.
