Differences between LSAW Steel Pipe and Spiral Welded Pipe

Apr 20, 2017Spiral welded pipe is made by using low carbon construction steel strip or low alloy structural steel strip to roll into a tube according to a certain helix angle (called the forming angle), and then welding the seam together. It can use the narrow band steel to produce steel pipe with large diameter. Spiral welded pipe is mainly used for oil and natural gas pipeline, its specifications are Equipments producing ERW spiral welded steel pipesERW ,Spiral weld Pipe Definition and Equipments producing ERW spiral welded steel pipes was established in 1989. We are located in MengcunCounty in Hebei Province, covering an area of 100,000 square meters, with a workshop of 25,000 square meters and registered capital of $7,500,000.Equipments producing ERW spiral welerw steel pipewhat is erw pipeerw pipe sizeserw pipe manufacturerhow is erw pipe madeerw steel tubeastm a53 erw steel pipeerw pipe chart

Compari of spiral steel pipe specifications Equipments producing ERW spiral welded steel pipes 2021-01-06 Tag Compari of spiral steel pipe specifications. erw welded pipe specifications. ERW stands for resistance welding. Resistance welding has the characteristics of high production efficiency, low cost, material saving Equipments producing ERW spiral welded steel pipesPetrosadid Electric Resistance/ Fusion Welded (ERW and EFW)ERW steel pipe is manufactured through low or high frequency resistances Electric Resistance. Welding seam is in longitudinal. During the ERW pipe welding processes, the electric current will make the heat when flow through the contact surface of the welding area. It will heat the 2 edges of the steel to a point that the edges can form a bond.Process and Characteristics of ERW Welded PipeJun 29, 2020Welded steel pipes are divided into straight seam welded pipes(ERW pipe, LSAW pipe) and spiral welded pipes in the form of welds. Production Process Straight seam welded pipe production process is simple, high production efficiency, low cost and rapid development. The strength of spiral welded pipe is generally higher than that of straight seam welded pipe. It is possible to use narrow blanks to produce welded pipes
