ASTM A672 EFW LSAW Steel Pipe yog tsim los rau siab - kev pabcuam siab ntawm qhov kub nruab nrab. ASTM A672 npog welded yeeb nkab fabricated los ntawm lub siab lub nkoj zoo phaj, nrog muab tub lim hlau ntxiv thaum lub sij hawm vuam txheej txheem. Cov yeeb nkab haum rau cov ntawv thov uas muaj cov kua dej, cov pa roj, thiab cov kev pabcuam chav

kev tsim khoom

Cov yeeb nkab yog tsim los siv cov txheej txheem hluav taws xob Fusion Vuam (EFW), uas suav nrog ntxiv cov hlau muab tub lim los tsim kom muaj tag nrho - nkag mus rau vuam. Longitudinal Submerged Arc Vuam (LSAW) yog ib qho txheej txheem siv los tsim cov kav dej, ua rau ob -welded seams

Qib, Chav Kawm thiab Cov Qauv

ASTM A672 cov kav dej yog tsim los ntawm cov qib siab - cov pa roj carbon zoo, uas muaj cov khoom siv dav, muaj zog, thiab zoo ductility

Qhov kev qhia tshwj xeeb txhais tau ntau qib thiab cov chav kawm kom haum raws li qhov xav tau sib txawv:

‌Qib:Qhia txog hom steel phaj siv, xws li B60, B65, B70, C55, C60, C65, C70 thiab lwm yam.

‌Chav kawm:Tsim hom kev kho cua sov ua thaum lub sijhawm tsim khoom, seb lub vuam puas tau kuaj xyuas hluav taws xob, thiab seb cov yeeb nkab puas tau dhau los ntawm kev sim siab. 10 Cov chav kawm muaj xws li Chav Kawm 13, 22, 32, thiab lwm yam.

‌Kev kho cua sov:Cov kev xaiv muaj xws li tsis muaj kev kho cua sov (xws li, Chav Kawm 10), kev ntxhov siab, normalizing, lossis normalizing thiab tempering, nyob ntawm chav kawm.

‌Cov Lus Qhia Ntxiv:Tus txheej txheem muab cov kev xav tau ntxiv rau kev kuaj ntxiv lossis kev kuaj xyuas

Kev tswj kom zoo

ASTM A672 EFW LSAW Steel Pipe undergos nruj tswj kev xeem, suav nrog:
