A252 Daim Ntawv Qhia Txog Qib 2 Hlau Yeeb Nkab: Zoo tagnrho rau Ob Chav Submerged Arc Welded Sewer Line Projects
Kawm txog A252 Qib 2 Steel Pipe:
A252 Qib 2 Hlau Yeeb Nkabyog cov pa roj carbon steel yeeb nkab tshwj xeeb tsim los siv rau hauv cov kav dej siab thiab kev siv cov txheej txheem.Nws yog tsim raws li ASTM (American Society for Testing and Materials) cov qauv, kom ntseeg tau cov qauv zoo thiab qhov tseeb.GRADE 2 lub npe qhia tias cov yeeb nkab steel yog tsim los siv submerged arc vuam lossis seamless vuam txoj kev.
Qhov tseem ceeb ntawm ob submerged arc vuam:
Ob chav submerged arc vuam, tseem hu ua DSAW, yog cov txheej txheem vuam tshwj xeeb uas siv los koom nrog ntu ntawm A252 GRADE 2 steel yeeb nkab.DSAW muaj ntau qhov zoo dua li lwm txoj kev vuam, suav nrog kev ua haujlwm zoo heev, vuam nrawm, qhov tsis sib xws tsawg, thiab kev tswj xyuas cov cua sov zoo heev.Nws ua kom muaj kev sib raug zoo ntawm cov kav dej, ua rau lawv tsis tshua muaj kev cuam tshuam, corrosion thiab kev puas tsuaj.

Vim li cas thiaj siv A252 Qib 2 steel yeeb nkab rau cov kav dej phwj tuaj?
1. ZOO TSHAJ PLAWS THIAB DURABILITY: A252 Qeb 2 steel yeeb nkab muaj lub zog tensile siab, ua rau nws tiv taus cov kev ntxhov siab thiab kev kub ntxhov.Lawv cov kav ntev ua kom lub neej ua haujlwm ntev dua, txo qhov xav tau kev hloov pauv ntau zaus lossis kho dua tshiab.
2. Corrosion Resistance: A252 GRADE 2 steel yeeb nkab yog tsim los tiv taus hnyav underground tej yam kev mob, nrog rau raug cov dej phwj tuaj, tshuaj thiab ya raws, tsis corroding los yog degrading.Cov yam ntxwv no ua rau kom muaj kev pabcuam lub neej ntawm cov kav dej phwj tuaj.
3. Nqi-zoo: A252 Qib 2 steel yeeb nkab muab cov nqi tsim nyog rau kev tsim cov kav dej.Lawv cov kev xav tau kev saib xyuas qis thiab kev ua neej nyob ntev tuaj yeem txuag cov nroog thiab cov neeg ua haujlwm cog lus tseem ceeb txuag lub sijhawm.
Daim ntawv thov ntawm A252 qib 2 steel yeeb nkab hauv dej phwj engineering:
A252 GRADE 2 steel yeeb nkab yog dav siv nyob rau hauv ntau yam ntawm cov kav dej phwj tuaj, suav nrog:
1. Cov kav dej hauv nroog: A252 Qib 2 steel kav yog siv dav hauv kev tsim kho cov kav dej hauv nroog hauv nroog kom zoo thauj cov dej khib nyiab los ntawm thaj chaw nyob thiab kev lag luam mus rau cov chaw kho mob.
2. Industrial Sewerage System: Industrial complexes yuav tsum muaj cov kav dej phwj muaj zog los tswj cov dej khib nyiab los ntawm cov chaw tsim khoom thiab lwm qhov chaw.A252 GRADE 2 steel yeeb nkab muab qhov tsim nyog lub zog thiab kav ntev rau hom kev lag luam dej khib nyiab no.
Hauv kev xaus:
Thaum nws los txogkab kav dejkev tsim kho, A252 GRADE 2 steel yeeb nkab ua ke nrog DSAW vuam thev naus laus zis muab lub zog tsis sib xws, ua haujlwm ntev thiab kev ua haujlwm tag nrho.Nws tshwj xeeb corrosion kuj, superior tensile zog thiab nqi-zoo ua rau nws zoo tagnrho rau ntau yam dej phwj infrastructure tej yaam num.Los ntawm kev siv cov khoom siv qib siab thiab cov txheej txheem vuam, cov nroog tuaj yeem ua rau kom muaj sia nyob thiab ua haujlwm ntawm lawv cov kav dej, txo cov nqi tu thiab xyuas kom muaj chaw huv, noj qab nyob zoo rau txhua tus.
