API 5L X65 PSL1 / PSL2LSAW Carbon Steel Yeeb Nkabyog tsim los ntawm kev tsim cov X65 steel daim hlau rau hauv ib puag ncig zoo ces welding lub seam los ntawm kev txiav arc vuam txheej txheem.Hauv kev tsim khoom ntawmAPI 5L X65 PSL1 & PSL2LSAW Carbon Steel Yeeb Nkab, daim hlau ntawm qib X65 yog tsim los ntawm lub tshuab moulding rau hauv cov duab puag ncig ces welded los ntawm ob-sided submerged arc vuam.Cov txheej txheem tsim khoom ntawm submerged arc welded ncaj seam steel yeeb nkab suav nrog JCOE txoj kev siv tshuab, coil tsim submerged arc vuam tshuab thiab UOE txoj kev siv tshuab.
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
