Kev tsim khoom

Cov txheej txheem ntawm kev tsim Longitudinal Submerged-arc Welded (LSAW) Pipe yog raws li nram no:

Ultrasonic phaj soj ntsuam → ntug milling → pre-bending → sib sau → Pre-welding → Internal vuam → Sab nraud vuam → Ultrasonic tshuaj xyuas → X-ray tshuaj ntsuam → nthuav → hydraulic kuaj → l.Chamfering → Ultrasonic tshuaj xyuas → X-ray tshuaj ntsuam → Sib nqus particle soj ntsuam ntawm lub raj kawg
