The Welded Steel Tubes
Welded steel pipe means welding pipe with steel plates and steel strips or steel coils.Longitudinal submerged arc welded steel pipe (LSAW),Electric Resistance Welded steel pipe (ERW),spiral submerged arc weled steel pipe (SSAW),Comparasion of Seamless steel pipe,Welded steel pipe owned higher precision in wall thickness and can be produced continuously.
Our EN 10219 Carbon Steel Welded Pipe exporters provide reliable and durable round structural pipes that are ideal for various applications in industries such as construction, oil and gas.
EN 10219 round ERW pipes are made of strip steel or steel plates and welded after crimping. They are widely used in steel structures, various specifications of oil casing, oil pipe and pipeline pipe, fluid transportation, fire protection and support, construction and other fields.
Technical requirements for welded steel pipes:
♦ Nondestructive testing
♦ Low temperature impact test
♦ Water pressure and eddy current test
♦ Flattening and expansion test
♦ Double inspection of welds
