Taw qhia
ASTM A106 cov kav hlau (tseem hu ua ASME SA106 cov kav dej) feem ntau siv hauv kev tsim cov roj thiab roj ua kom huv, cov chaw tsim hluav taws xob, cov nroj tsuag roj av, cov rhaub dej kub, thiab cov nkoj uas cov kav dej yuav tsum nqa cov kua thiab cov nkev uas muaj qhov kub thiab txias siab. . Vim nws qhov kev siv tshwj xeeb, ASTM A106 cov yeeb nkab steel tuaj yeem tsuas yog cov yeeb nkab hlau tsis sib haum, thiab nws tseem tuaj yeem txuas cov yeeb nkab steel.
ASTM A106 steel yeeb nkab muaj nyob rau hauv qhov loj me ntawm 1/2 txog 28 ntiv tes, thiab hauv cov txheej txheem yeeb nkab ntawm 10 txog 160 (raws li ASME B36.10 kev qhia tshwj xeeb).
Txheej txheem
Cov khoom siv raw yog tua cov hlau, uas tsim nyog rau kev pabcuam kub, nws tau tsim tawm hauv ib lossis ntau txoj hauv kev hauv qab no: qhib lub qhov cub tawg, tshuab pa oxygen hloov lossis hluav taws xob rauv. Kev zom zaws thawj zaug tuaj yeem ua ke nrog degassing lossis kho kom zoo ib leeg. Hlau tuaj yeem raug pov rau hauv qhov chaw lossis txuas ntxiv mus.
NPS 1-1 / 2" thiab tom qab ntawd lawv muaj nyob rau hauv qhov ua tiav kub lossis txias txias yam. 2-nti thiab loj dua NPS cov kav dej feem ntau yog kub dov. Cov yeeb nkab kub kub tsis tas yuav tsum tau kho cua sov. Cov kab txias txias yuav raug kho cua sov tom qab qhov txias txias dhau los.
Hais txog cov khoom siv qib, A106 yeeb nkab tau tsim hauv qib A, B, thiab C. Cov tshuaj lom neeg muaj pes tsawg ntawm peb qib ntawm ASTM A106 tau qhia hauv cov lus hauv qab no:

Kev qhia tshwj xeeb
Phab Ntsa Thickness - Yam tsawg kawg ntawm phab ntsa tuab ntawm txhua qhov chaw yuav tsum tsis txhob ntau dua 12.5% hauv qab cov npe tshwj xeeb.
Qhov hnyav: qhov hnyav ntawm qhov ntev yuav tsum tsis sib txawv ntau dua 10% saum toj no thiab 3.5% qis dua qhov tau teev tseg. NPS 4 thiab hnyav dua hauv pawg. Qhov loj me yuav raug ntsuas cais los ntawm qhov ntev.
