From the analysis data of ERW steel pipe scrapping, it can be seen that the roll adjustment process plays a very important role in the production of welded pipes. That is, in the production process, if the rolls are damaged or worn seriously, some rolls should be replaced in time in the unit, or a certain type of ERW…
Read MoreWhat is a straight seam welded pipe? Straight seam welded pipe is a steel pipe with a straight weld seam parallel to the longitudinal direction of the steel pipe, also known as a straight seam steel pipe, which is made by bending a steel plate or strip and then welding the joints. The production process of straight seam welded…
Read MoreSpiral welded pipe (SSAW) rust removal and anticorrosion process introduction: Rust removal is an important part of the pipeline anticorrosion process. At present, there are many rust removal methods, such as manual rust removal, sand blasting and pickling rust removal, etc. Among them, manual rust removal, mechanical rust removal and painting rust removal (anti-corrosion brushing oil) are relatively common…
Read MoreSpiral welded pipe (ssaw) is a kind of steel pipe that combines low-carbon and environmentally friendly alloy structural steel and low-alloy structural characteristics into pipe material and electric welding. How can the reliability of the spiral pipe be improved in the process of adoption? When we store it, we need to ensure the upper block and the lower pad,…
Read MoreSpiral welded pipes (SSAW) for water conservancy projects are generally spiral welded steel pipes with relatively large diameters, because the water passing through per unit time is large, which can greatly improve work efficiency. Since the inner wall of the spiral steel pipe is constantly washed by water, the inner wall is generally not treated with anti-corrosion treatment, but…
Read MoreSAW pipe (Submerged Arc Welding Steel Pipe), it can be classified into longitudinal submerged arc welding steel pipe (LSAW steel pipe) and spiral submerged arc welding steel pipe (SSAW steel pipe). SAW is a manufacturing process using submerged arc welding of steel,this process produces high current density, which prevents the flux layer from losing heat quickly and concentrates in…

Read MoreSeamless pipe has better pressure capacity, strength is higher than ERW welded pipe. So it is widely applied in high pressure equipment, and thermal, boiler industries. Generally the welding seam of the welded steel pipe is the weak point, the quality affect overall performance. Seamless pipe vs welded steel pipe: 1. Appearance difference Seamless steel pipe used steel billet…
