Option 2 - is to set out the end-plate so that in intrudes into the heel by approximately 5-6 mm,again,allowing for a double sided weld.Option 1 - may be used with a partial,extended,or full depth Large Diameter Steel Tube With Best Price LSAW Longitudinally Submerged Arc Welded Steel pipes in leaflets plate as raw material,the steel plate in the mold or molding machine pressure (volume) into using double-sided submerged arc welding and flaring from production.The coherence of cutter head and plate clamping system guarantees the invariable parameters during the entire milling process LSAW PIPE Longitudinally Submerged Arc Welding (LSAW) pipes use single plate steel as raw material,applied double-sided submerged arc welding.The finished products have larger specifications and the welding joints have excellent ductility,plasticity and good sealing.PRODUCT SPECIFICATION STANDARD API Spec 5L PSL-1,API Spec 5L PSL-2,ASTM A53,ASTM A252,LSAW (Longitudinally Submerged Arc Welded Steel pipes) in leaflets plate as raw material,the steel plate in the mold or molding machine pressure (volume) into using double-sided submerged arc welding and flaring from production.The developing trend of LSAW steel pipe in the future:They are usually made from longitudinally submerged arc welding (LSAW) pipes subjected to hot bending process including quenching and tempering process,which often deteriorates the impact property of the welded pipe. A hot-bended LSAW pipe with a wall thickness of 30.8 mm was fabricated by double-sided four wires submerged arc welding with LSAW (Longitudinally Submerged Arc Welded Steel pipes) in leaflets plate as raw material,the steel plate in the mold or molding machine pressure (volume) into using double-sided submerged arc welding and flaring from production.JCOE pipes The mill adopts continuous axis contorting J-C-O(J-ing,C-ing and O-ing)process with characteristics of Longitudinally Submerged Arc Welding is abreviated as LSAW.API 5L X70 LSAW JCOE Welded Steel Pipe is produced by using a single plate as a raw material,pressing (rolling) the steel plate into a tube blank in a mold or a molding machine,and using double-sided submerged arc welding and expanding the diameter.The finished product has a wide The company can produce 100,000 tons of corrosion-resistant metallurgical composite bimetal longitudinally welded steel pipes per year.The products are mainly used in the manufacture of highly corrosive petroleum and natural gas transmission pipelines,highly corrosive chemical medium transmission pipelines and equipment,seawater desalination equipment water pipelines and seawater5.Pre-welding Join the formed longitudinally welded steel pipe and use gas shielded welding (MAG) for continuous welding; 6.Internal welding use longitudinal multi-wire submerged arc welding (four wires) to weld on the inner side of the straight seam steel pipe; 7.Apr 30,2021&0183;7.External welding use longitudinal multi-wire submerged arc welding to weld on the outside of the longitudinal submerged arc welded steel pipe; 8.Ultrasonic inspection I 100% inspection of the inner and outer welds of the longitudinally welded steel pipe and the base materials on both sides ofDec 29,2012&0183;We can produce longitudinally welded steel pipes with diameter range of 21.3 to 610mm and wall thickness range of 1.8 to 16mm; And spiral double-sided submerged arc welded steel pipes with diameter range of 219 to 3,048mm and wall thickness range of 5.0 to 30mm.
