Hebei Zhonghai Steel Pipe Manufacturing Corporation - China supplier of seamless steel pipe, API 5L line pipe, ERW welded steel pipe, spiral steel pipeHow is the theoretical weight of spiral steel pipe calculated?The theoretical weight of steels is obtained by calculating nominal dimensions and density (which is called specific weight in the past). This is directly related with the steel length, the cross section area, and the allowable size deviation. Because of the allowable deviation in the process of manufacturing, the calculated theoretical weight is somehow different from the actual value, and Hebei Jinsuo Steel Pipe Manufacturing Spiral Inside and Outside Epoxy Coated Steel Pipe, Inside Epoxy Hebei Jinsuo Steel Pipe Manufacturing Spiral Hebei PuLanke is devoted to manufacture and exporte inside and outside epoxy coated steel pipe, inside epoxy outside polyethylene coated steel pipe, spiral steel pipe and epoxy compound powder coating with competitive price.
