Kev tsim cov txheej txheem ntawm Longitudinal Submerged-arc Welded Pipe:

lsaw pipe manufacturers

LSAW Tubeadopts submerged arc vuam tshuab, siv muab tub lim welding, particle tiv thaiv flux faus arc.

LSAW yog cov lus Askiv luv ntawm submerged arc welded ncaj seam steel yeeb nkab.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

Bending Test—Qhov ntev txaus ntawm cov yeeb nkab yuav tsum sawv ntsug ntawm qhov txias ntawm 90 ° nyob ib ncig ntawm lub cylindrical mandrel.

Flattening test-Txawm hais tias kev sim tsis tas yuav tsum tau ua, cov yeeb nkab yuav tsum muaj peev xwm ua tau raws li qhov yuav tsum tau ua kom tiav qhov kev xeem.

Hydrostatic Test -tshwj tsis yog raws li kev tso cai, txhua qhov ntev ntawm cov yeeb nkab yuav tsum raug kuaj xyuas hydro-static yam tsis muaj dej los ntawm cov yeeb nkab phab ntsa.

Nondestructive electric test-Raws li lwm txoj hauv kev ntsuas hydro-static, tag nrho lub cev ntawm txhua cov yeeb nkab yuav tsum tau sim nrog kev ntsuas hluav taws xob tsis zoo.qhov twg tsis muaj kev ntsuas hluav taws xob ua tiav, qhov ntev yuav tsum raug cim nrog cov ntawv "NDE"
