Tag Nrho Cov Nqi
ASTM A513 Hom raug sib txawv raws li cov xwm txheej sib txawv lossis cov txheej txheem ntawm cov yeeb nkab hlau.
ASTM A513 cov yeeb nkab puag ncig hom 5 qib feem ntau yog:
1008, 1009, 1010, 1015, 1020, 1021, 1025, 1026, 1030, 1035, 1040, 1340, 1524, 4130, 4140.
Puag ncig
Plaub fab lossis duab plaub fab
Lwm cov duab
xws li cov duab streamlined, hexagonal, octagonal, puag ncig sab hauv thiab hexagonal lossis octagonal sab nraud, ribbed sab hauv lossis sab nraud, triangular, rounded rectangular, thiab D shapes.
Hlau kub dov los yog txias dov
Cov khoom siv raw rau kev tsim cov Hlau Kub-dov lossis Txias-dov tuaj yeem tsim los ntawm txhua txoj kev.
Hlau Kub-Kuav: Hauv cov txheej txheem ntau lawm, cov hlau kub dov thawj zaug raug cua sov ntawm qhov kub siab, tso cai rau cov hlau kom 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 kub dov, cov khoom siv feem ntau yog scaled thiab deformed.
Hlau Txias-KuavCov hlau uas dov txias lawm ces dov ntxiv tom qab cov khoom txias lawm kom tau qhov loj thiab zoo li koj xav tau. Cov txheej txheem no feem ntau ua thaum sov li chav tsev thiab ua rau cov hlau zoo dua thiab muaj qhov loj me dua.
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.

Kev siv barcoding yog qhov siv tau ua ib txoj kev txheeb xyuas ntxiv.
Cov kav dej yuav tsum tau coated nrog ib zaj duab xis ntawm roj ua ntej xa khoom kom tiv thaiv xeb.
Qhov kev txiav txim puas yuav tsum qhia meej tias cov yeeb nkab yuav tsum xa tuaj yam tsis muajroj tiv thaiv xeb, zaj duab xis ntawm cov roj uas tshwm sim los ntawm kev tsim khoom yuav nyob twj ywm rau ntawm qhov chaw.
Nws tuaj yeem tiv thaiv qhov saum npoo ntawm cov yeeb nkab kom tsis txhob cuam tshuam nrog cov dej noo thiab cov pa oxygen hauv huab cua, yog li ntawd zam kev xeb thiab xeb.
Tseeb tiag, thaum cov roj nplua nyeem yooj yim lossis cov roj zaj duab xis yooj yim tuaj yeem muab qee qib kev tiv thaiv ib ntus, rau cov ntawv thov uas xav tau qib kev tiv thaiv siab dua, kev kho mob tiv thaiv xeb tsim nyog yuav tsum tau xaiv rau ntawm ib kis zuj zus.
Piv txwv li, rau cov kav dej faus, ib qho3PE(peb txheej polyethylene) txheej siv tau los muab kev tiv thaiv xeb mus sij hawm ntev; rau cov kav dej, ib qhoFBE(fusion-bonded epoxy hmoov) txheej tuaj yeem siv tau, thaumgalvanizedkev kho mob tuaj yeem yog ib qho kev xaiv zoo hauv cov chaw uas xav tau kev tiv thaiv zinc corrosion.
Nrog cov thev naus laus zis tiv thaiv xeb tshwj xeeb no, lub neej ua haujlwm ntawm cov yeeb nkab tuaj yeem ntev dua thiab nws txoj haujlwm tseem nyob ruaj khov.
