LSAW Transmission steel pipe

API 5L LSAW Transmission steel pipe for natural gas and petroleum

LSAW steel pipe refers to Longitudinal Submerged-Arc Welded Steel Pipe, which is made of hot-rolled steel plate or coils. LSAW steel pipe always goes to the big-sized welded pipe, which can’t be manufactured by electric resistance welding technique. API 5L LSAW steel pipes ( Double Submerged arc welded) are used to convey low & high pressure petroleum, natural gas or other thick pipeline system. LSAW could produce the thick wall thickness max. to 120mm. specification of API 5L LSAW Transmission steel pipe Line Pipe: API 5L PSL1/PSL2,GR.B/X42/X46/X52/X56/X60/X65/X70 Outside Diameter: Φ406mm-Φ1626mm (16″-64″) Wall thickness: 6.4mm-54mm (1/4″-21/8″) Grades: API 5L (A, B, X42-X80) […]
