Manufacturing Process of  API 5L X65/X70 PSL1/PSL 2  Welded Pipe:

api 5l x52 psl2

API 5L X65 PSL1/PSL2 LSAW Carbon Steel Pipe is manufactured by forming the X65 steel plates into a round shape then welding the seam through automatically arc welding process. In the production of  API 5L X65 PSL1&PSL2 LSAW Carbon Steel Pipe, plates of grade X65 are formed by the molding machine into round shape then welded through double-sided submerged arc welding.The production process of submerged arc welded straight seam steel pipe includes JCOE forming technology, coil forming submerged arc welding technology and UOE forming technology.

The process of manufacturing Longitudinal Submerged-arc Welded(LSAW) Pipe is as follows:

Ultrasonic plate probing → edge milling → pre-bending → forming → Pre-welding → Internal welding→ External welding → Ultrasonic inspection → X-ray inspection → Expanding → hydraulic test →l. Chamfering → Ultrasonic inspection → X-ray inspection → magnetic particle inspection at tube end
