ASTM A513 hlauyog cov yeeb nkab carbon thiab alloy steel thiab lub raj ua los ntawm cov hlau kub-dov lossis txias-dov ua cov khoom siv raw los ntawm kev vuam tsis kam (ERW) txheej txheem, uas yog siv dav hauv txhua hom kev kho tshuab.
Hom 1 muaj peev xwm muab faib ua 1a thiab 1b.
Hom 1a (AWHR): "raws li-welded" los ntawm cov hlau kub-kuav (nrog rau qhov ntsuas zeb).
Cov yeeb nkab no yog vuam ncaj qha los ntawm cov hlau kub dov nrog hlau oxide (qib zeb) tsim thaum lub sijhawm dov. Hom yeeb nkab no feem ntau siv rau hauv cov ntawv thov uas qhov kev ua tiav ntawm qhov chaw tsis tseem ceeb vim tias qhov chaw muaj qib zeb.
Hom 1b (AWPO): "raws li-welded" los ntawm cov hlau kub-kuav pickled thiab oiled (milled scale).
Cov yeeb nkab no yog vuam los ntawm cov hlau kub uas tau raug pickled thiab roj thiab nws tus cwj pwm los ntawm kev tshem tawm cov nplai zeb. Kev kho pickling thiab roj tsis yog tsuas yog tshem tawm cov oxidation ntawm qhov chaw xwb tab sis kuj muab qee qhov kev tiv thaiv xeb thiab lubrication thaum lub sijhawm ua haujlwm, ua rau cov yeeb nkab no tsim nyog dua rau cov ntawv thov uas xav tau qhov chaw huv dua lossis cov xwm txheej ua haujlwm nruj dua me ntsis.

Kub-kuav
Hauv cov txheej txheem ntau lawm, cov hlau kub dov thawj zaug raug cua sov ntawm qhov kub siab, ua rau cov hlau dov rau hauv lub xeev yas, uas ua rau nws yooj yim hloov cov duab thiab qhov loj ntawm cov hlau. Thaum kawg ntawm cov txheej txheem dov kub, cov khoom siv feem ntau yog scaled thiab deformed.
Cov raj yuav tsum tau ua los ntawmhluav taws xob-tsis kam-welded (ERW)txheej txheem.
ERW yeeb nkab yog cov txheej txheem ntawm kev tsim ib qho vuam los ntawm kev coiling ib yam khoom siv hlau rau hauv ib lub tog raj kheej thiab siv kev tiv thaiv thiab siab raws nws qhov ntev.
Cov hlau yuav tsum ua raws li cov kev cai ntawm cov tshuaj lom neeg uas tau teev tseg hauv Rooj 1 lossis Rooj 2.

Pheej yig duaCov txheej txheem vuam rau cov hlau kub dov ua rau ASTM A513 Hom 1 pheej yig dua piv rau cov khoom siv txias.
Ntau yam kev sivASTM A513 Hom 1 yog tsim rau ntau yam kev siv, suav nrog cov khoom siv hauv tsev, cov thav duab, cov txee, thiab ntau ntxiv. Nws qhov kev hloov pauv tau yooj yim hauv ntau qhov chaw thiab kev ua haujlwm ua rau nws yog qhov kev xaiv nrov rau kev lag luam xws li tsheb, kev tsim kho, thiab tshuab.
Kev vuam zoo heevCov tshuaj lom neeg sib xyaw ntawm ASTM A513 Hom 1 zoo rau kev vuam, thiab nws tuaj yeem vuam siv siv feem ntau cov txheej txheem vuam ib txwm muaj, ua rau nws siv tau zoo dua hauv ntau qhov chaw tsim khoom.
Lub zog zoo thiab kev tawv tawvTxawm hais tias tsis muaj zog npaum li qee cov hlau sib xyaw lossis cov hlau kho, nws ua tau raws li qhov yuav tsum tau muaj zog txaus rau ntau yam kev siv hauv kev tsim kho thiab kev siv tshuab. Kev ua ntxiv, xws li kev kho cua sov, kuj tseem tuaj yeem txhim kho cov khoom siv kho tshuab ntawm cov yeeb nkab kom ua tau raws li qhov xav tau tshwj xeeb.
Qhov Chaw TiavHom 1b muab qhov chaw huv dua, uas yog qhov zoo rau cov ntawv thov uas xav tau qhov chaw tiav zoo thiab qhov twg xav tau pleev xim lossis npaj qhov chaw ntxiv.
ASTM A513 Hom 1 muab qhov sib npaug zoo ntawm tus nqi, kev ua tau zoo, thiab kev hloov pauv tau yooj yim, ua rau nws haum rau ntau yam kev siv tshuab thiab kev teeb tsa qhov twg xav tau cov yeeb nkab pheej yig nrog cov khoom siv kho tshuab zoo.
