EN 10219 S355J2H SAWL Steel Yeeb Nkab
Khoom siv:S235JRH, S355JRH, S355J0H, S355J2H, S355K2H...

SAWL lub longitudinal submerged arc welded yeeb nkab JCOE ntau lawm kab
Txoj kab uas hla 400-1422mm (16-56inch), thickness 8mm txog 60mm.
SAWL kav dej yog dav siv nyob rau hauv onshore thiab offshore conveyance ntawm roj, roj, dej, thee slurry, thiab kuj siv rau kev tsim kho, choj, ntauwd, fais fab engineering, tshuaj, dej hiav txwv platform thiab lwm yam.

Txheej txheem ntau lawm:
☆Phaj Ultrasonic Inspection:Txhua phaj yog thawj zaug puv-phaj ultrasonic tshuaj xyuas tom qab nkag mus rau hauv cov txheej txheem
☆Phaj Ntug Milling:Lub Phaj npoo yog milled los ntawm Ntug Milling Tshuab kom tau qhov yuav tsum tau muaj qhov dav, parallelism thiab bevel kaum sab xis;
☆Phaj Ntug Crimping:Ob lub npoo ntawm lub phaj yog crimped ntawm lub tshuab Crimping kom tau lub vojvoog uas xav tau;
☆Kev tsim:Thawj ib nrab ntawm lub phaj yog pub ib kauj ruam mus rau hauv cov yeeb nkab Forming Xovxwm los tsim lub phaj rau hauv "J" zoo li. Tom qab ntawd lwm ib nrab ntawm lub phaj yog nias ib kauj ruam los ua lub phaj rau hauv "C" zoo li. Qhov kawg stroke yog nias lub phaj rau hauv qhov qhib "O" zoo;
☆Pre-welding:Ob lub npoo ntawm qhov qhib seam yeeb nkab yuav tsum tau coj los ua ke los ntawm tack welding tshuab ces welded los ntawm tack welder siv hlau active-gas arc vuam (MAG) txheej txheem;
☆Sab hauv Vuam:Cov yeeb nkab yog welded los ntawm sab hauv ntawm cov yeeb nkab los ntawm multi-pass tandem submerged-arc vuam (max. plaub hlau);
☆Sab nraud Welding:Cov yeeb nkab yog welded los ntawm sab nraud ntawm cov yeeb nkab los ntawm multi-pass tandem submerged-arc vuam;
☆Ultrasonic Test thiab X-ray Inspection:Lub welded cheeb tsam ntawm ob sab ntawm lub vuam yog 100 feem pua ​​​​kuaj los ntawm tsis siv neeg ultrasonic tester.
☆Pipe Ends Beveling:Tag nrho cov kav dej tsim nyog los ntawm kev xeem dhau los yog raug rau cov yeeb nkab kawg ua kom tau qhov yuav tsum tau muaj bevel dimension.
