Welded pipe Can be divided into straight seam and spiral welded-pipe

Straight seam welded-pipe

The production process is simple, the production efficiency is high, the cost is low, and the development is rapid.

Spiral welded pipe

The strength is generally higher than that of the straight seam welded tube, and a narrower blank can be used to produce a larger diameter pipe, and also a blank pipe having the same diameter can be used to produce a different diameter pipe. However, compared with the straight seam pipe of the same length, the length of the weld seam increases by 30 to 100%, and the production speed is low. Therefore, the smaller diameter welded-pipe mostly adopts straight seam welding, and the large diameter welded pipe adopts mostly spiral welding.
