Dab tsi yog Submerged Arc Welded Pipe?
Submerged arc welded yeeb nkabyog ib hom kauv welded steel yeeb nkab ua los ntawm steel sawb raws li raw khoom, tsim los ntawm chav tsev kub extrusion, thiab welded siv ib tug tsis siv neeg ob -hlau ob-sided submerged arc vuam txheej txheem. Cov yeeb nkab steel no muaj qhov zoo xws li cov txheej txheem tsim khoom yooj yim, kev ua haujlwm siab ntau lawm, thiab tus nqi qis, muab qhov zoo rau kev txhim kho.
Cov qauv zoo li cas tau txais rau S235JRH submerged arc welded yeeb nkab?
S235JRH submerged arc welded yeeb nkabyuav tsum ua raws li cov qauv kev ua tau zoo xws li EN 10219-1/2 thiab EN 10210-1, nrog rau cov kev ntsuas tshwj xeeb uas tsis muaj kev puas tsuaj (NDT) cov cai rau submerged arc welds hauv EN 10246-9 lossis EN 10246-10.
Qhov txawv ntawm DSAW thiab LSAW welded yeeb nkab yog dab tsi?
Qhov sib txawv tseem ceeb yog DSAW (ob chav -sided submerged arc welded) yeeb nkab yog ib hom tshwj xeeb ntawmLSAW (longitudinal submerged arc welded) yeeb nkab, nrog welds ntawm ob sab hauv thiab sab nrauv, thaum LSAW yeeb nkab feem ntau tsuas muaj qhov sib txuas ntawm sab nrauv. DSAW ob - sab vuam txheej txheem ua kom tuab dua, muaj zog welds thiab feem ntau yog siv rau hauv siab - siab, loj - daim ntaub ntawv txoj kab uas hla.
Dab tsi engineering tej yaam num yog S235JRH submerged arc welded kav tsuas yog siv nyob rau hauv?
S235JRH submerged arc welded kavFeem ntau yog siv nyob rau hauv cov txheej txheem engineering tej yaam num xws li txuas hniav, vaj tse, thiab tunnels, raws li zoo raws li industrial thiab infrastructure tej yaam num xws li dej, petrochemical, thiab ua liaj ua teb irrigation systems. Lawv cov kev ua haujlwm vuam zoo heev thiab tus nqi-kev ua tau zoo ua rau lawv haum rau ntau yam kev lag luam, kev siv tshuab ua haujlwm, thiab kev siv dej thiab roj.
Dab tsi yuav tsum tau ceev faj thaum thauj S235JRH submerged arc welded kav?
Txhawm rau kom muaj kev nyab xeeb ntawm kev thauj mus losS235JRH submerged arc welded kav, yuav tsum tau ceev faj hauv qab no:
1, Waterproof ntim: Coated steel kav yog rhiab heev rau cov av noo ib puag ncig, tshwj xeeb tshaj yog thaum lub sij hawm thauj hiav txwv, qhov twg dej hiav txwv thiab noo noo yuav nkag mus rau hauv lub ntim, ua rau lub txheej. Yog li ntawd, cov kav hlau yuav tsum tau qhwv nrog cov ntaub ntawv tsis muaj dej (xws li zaj duab xis yas lossis ntawv tsis muaj dej) kom ntseeg tau tias lawv nyob twj ywm qhuav thaum thauj.
2, Kev tiv thaiv kev sib tsoo: Cov txheej txheej txheej ntawm cov kav hlau coated yog raug rau kev puas tsuaj los ntawm kev cuam tshuam lossis kev sib txhuam. Nws raug nquahu kom siv cov ntaub ntawv cushioning (xws li cov ntaub qhwv ntsej muag, cov ntaub qhwv ntoo, lossis cov ntaub qhwv roj hmab) kom cais cov kav hlau thiab tsis txhob sib cuag ncaj qha. Tsis tas li ntawd, kev tiv thaiv lub kaus mom lossis lub tes tsho yuav tsum tau siv rau ntawm qhov kawg ntawm cov kav dej steel kom tiv thaiv kev puas tsuaj rau qhov kawg txheej.
3, Kev ntim khoom ruaj ntseg: Cov kav hlau yuav tsum tau muab khi ruaj khov nrog cov hlua hlau lossis hlua kom tiv thaiv kev txav los yog kev sib tsoo thaum lub sij hawm thauj mus los vim lub nkoj roughness. Thaum bundling, tsis txhob overtightening los tiv thaiv kev puas tsuaj rau txheej.
