What are the advantages of double-sided submerged arc welded pipe?

2022-10-10

The development prospect of the double-sided submerged arc welded pipe industry is very good, because it brings more benefits to the enterprise when in use, so it is favored by customers. In order to let everyone know more, next we will talk about the advantages of double-sided submerged arc welded pipe, hoping to bring help to more people.

An analysis of the factors that lead to porosity in the weld of double-sided submerged arc welded pipes.

2022-09-30

As we all know, the quality of double-sided submerged arc welded pipe is determined by the quality of the weld. Once the weld of double-sided submerged arc welded pipe produces pores, it will not only affect the density of the weld, cause pipeline leakage, but also become the corrosion inducing point, seriously reduce the strength and toughness of the weld. Generally speaking, the moisture, dirt, oxide scale and iron filings in the flux, welding composition and covering thickness, steel plate surface quality, steel plate side plate treatment, welding process and steel pipe forming process may be the causes of weld porosity.

Advantage sharing of double-sided submerged arc welded pipe

2022-09-21

Double-sided submerged arc welded pipe is a welded steel pipe made of steel plate or steel strip after crimping. It has the advantages of small size deviation, uniform wall thickness, simple production process, high production efficiency, many varieties and specifications, and less equipment investment. However, because the welding performance of welded steel pipes is lower than that of seamless steel pipes, the utilization rate in petrochemical plants is very low. Double-sided submerged arc welded pipe is divided into straight seam and spiral seam according to the weld form.
