ASTM A513 steel hlauyog cov pa roj carbon thiab alloy steel yeeb nkab thiab raj ua los ntawm kub dov los yog txias dov hlau ua raw khoom los ntawm kev ua haujlwm vuam (ERW), uas yog siv dav hauv txhua yam ntawm cov khoom siv tshuab.
Hom 1 tuaj yeem muab faib ua 1a thiab 1b.
Type 1a (AWHR): "raws li-welded" los ntawm kub-dov hlau (nrog zeb nplai).
Daim ntawv ntawm cov yeeb nkab no yog welded ncaj qha los ntawm kub dov hlau nrog hlau oxide ( zeb nplai) tsim thaum dov.Hom yeeb nkab no feem ntau siv rau hauv cov ntawv thov uas qhov kev ncaj ncees ntawm qhov chaw tsis yog qhov tseem ceeb vim tias qhov chaw muaj cov nplai zeb.
Type 1b (AWPO): "raws li-welded" los ntawm kub dov pickled thiab oiled steel (mill scale tshem tawm).
Daim ntawv ntawm cov yeeb nkab no yog welded los ntawm kub-kuav los tiag steel uas tau raug pickled thiab oiled thiab yog yus muaj los ntawm kev tshem tawm ntawm lub zeb nplai.Kev kho cov dej thiab roj tsis tsuas yog tshem tawm cov oxidation saum npoo xwb tab sis kuj muab qee qhov kev tiv thaiv corrosion thiab lubrication thaum ua, ua rau cov yeeb nkab no tsim nyog rau cov ntawv thov uas yuav tsum tau ua kom huv si los yog ua kom nruj me ntsis.

Kub dov
Nyob rau hauv cov txheej txheem ntau lawm, kub-kuav los tiag steel yog thawj rhuab nyob rau hauv high kub, cia cov hlau yuav dov nyob rau hauv ib tug yas lub xeev, uas ua rau nws yooj yim los hloov cov duab thiab loj ntawm cov hlau.Thaum kawg ntawm cov txheej txheem kub dov, cov khoom feem ntau yog scaled thiab deformed.
Tubes yuav tsum tau ua los ntawm covHluav taws xob tsis kam-welded (ERW)txheej txheem.
ERW yeeb nkab yog txheej txheem ntawm kev tsim cov vuam los ntawm coiling cov khoom siv hlau rau hauv lub tog raj kheej thiab siv cov kev tiv thaiv thiab siab raws nws qhov ntev.
Cov hlau yuav tsum ua raws li cov txheej txheem tshuaj lom neeg uas tau teev tseg hauv Table 1 lossis Table 2.
