Industrial processing for welded steel pipe

Welded steel pipe is a general term for a certain class of steel pipe. There are some cracks on the surface of the steel pipe after processing such as welding. As you know, it can be divided into two types, one is spiral welded steel pipe and the other type is straight line welded steel pipe. According to the name of welded steel pipe, we can see spiral traces on the combined surface. The intensity of spiral welded steel pipe is much more stronger than straight welded pipe and the weld length is much more long. Because of the long welding length, the production efficiency is lower compared with spiral welded steel pipe. The straight tube is formed between two parallel vertical pipe so the surface has obvious signs of a straight line. In addition, ERW industrial efficiency is high and more and more steel pipe manufacturers are willing to take this method to process steel pipes.

Welded steel pipe is similar to the seamless steel pipe in the past. However, with the development of china’s iron and steel technology, welded steel pipe is obviously more flexible, which can be welded according to the demand of finished products. Therefore, welded steel pipe is the dominated application in the modern situation. Welded steel pipe can be classified into several types in terms of application such as general welded pipe, galvanized steel pipe, as well as pressure pipe. Taking galvanized steel pipe as an example, we should take square steel pipe with a certain caliber standard going through welding process to form welded square pipe. After that, in order to improve the corrosion resistance of welded steel pipe as well as its service life, it will be painted with a layer of zinc on the surface by the method of cold galvanizing or hot dipped plating. The price of galvanized steel pipe will naturally be slightly higher. According to different standards, the price is also different from 4600-6000 yuan.

Every day, the industrial production will use a large number of welded steel pipe for different fields. Generally speaking, the requirements of steel pipes such as round steel pipe are relatively low. It can be used for transporting liquids without corrosive performance. Besides, the welding method is also different hinge on application scope such as arc welding, gas pipe, electric welded pipe and so on. Hope you can be interested in our products and contact us.
