    Ib qho ntawm cov txiaj ntsig tseem ceeb ntawm kev siv kauv submerged arc welded steel yeeb nkab rau cov kab hauv av yog nws lub zog siab thiab kav ntev.Cov txheej txheem spiral welding tsim cov yeeb nkab muaj zog thiab txhim khu kev qha uas tuaj yeem tiv taus lub siab thiab qhov hnyav ntawm kev faus hauv av.Lub zog no yog qhov tseem ceeb rau kev tiv thaiv cov xau thiab ua kom muaj kev ncaj ncees mus ntev ntawm cov kav dej.

    Tsis tas li ntawd, SSAW steel yeeb nkab tiv taus corrosion, ua rau nws yog ib qho kev xaiv zoo tshaj plaws rau cov ntawv siv hauv av uas cov kav dej raug dej thiab lwm yam ib puag ncig.Qhov kev tiv thaiv corrosion no pab txuas ntxiv lub neej ntawm koj cov kav dej thiab txo qhov kev xav tau ntawm kev saib xyuas thiab kho ntau zaus.

    Pipe rau Underground Dej Kab

    Lwm qhov txiaj ntsig ntawm kev siv kauv submerged arc welded steel yeeb nkab rau cov kab hauv av yog nws yooj yim thiab yoog raws.Cov txheej txheem kauv vuam tuaj yeem tsim cov kav dej sib txawv, ua rau nws tsim nyog rau ntau yam kev siv yeeb nkab dej.Tsis tas li ntawd, qhov yooj ntawm SSAW steel yeeb nkab ua rau nws yooj yim rau nruab thiab khiav lag luam, tshwj xeeb tshaj yog nyob rau hauv cov cheeb tsam uas nyuaj struts lossis obstacles.

    ib.Txoj kev deoxidation yog tsim raws li hauv qab no:

    FF: Ua tiav cov hlau uas muaj nitrogen khi cov ntsiab lus kom txaus los khi muaj nitrogen (xws li min. 0,020% tag nrho Al lossis 0,015% soluble Al).

    b.Tus nqi siab tshaj plaws rau nitrogen tsis siv yog tias cov tshuaj muaj pes tsawg leeg pom qhov tsawg kawg nkaus Al ntsiab lus ntawm 0,020% nrog qhov tsawg kawg nkaus Al / N piv ntawm 2: 1, lossis yog tias muaj lwm yam N-binding ntsiab.Cov ntsiab lus N-binding yuav tsum tau sau rau hauv Cov Ntaub Ntawv Tshawb Fawb.

    Ntxiv rau lub zog, durability, thiab saj zawg zog, kauv submerged arc welded steel yeeb nkab yog tus nqi zoo piv rau lwm hom yeeb nkab.Cov txheej txheem spiral welding txo cov nqi tsim khoom, ua rau nws muaj kev xaiv pheej yig dua rau cov kav dej loj loj.Lub sijhawm ua haujlwm ntev thiab kev saib xyuas tsis zoo ntawm SSAW steel yeeb nkab kuj tseem ua rau kev txuag nyiaj tag nrho hauv lub neej ntawm cov kab dej.

    SSAW Tube

    Zuag qhia tag nrho, muaj ntau yam zoo rau kev siv kauv submerged arc welded steel yeeb nkab rau hauv av kab, nrog rau lub zog siab, durability, corrosion resistance, yooj, thiab nqi-zoo.Cov kev ua tau zoo no ua rau nws muaj kev ntseeg siab thiab ua tau zoo rau kev thauj mus los hauv av, txawm tias yog rau kev tsim kho hauv nroog, kev siv lag luam, lossis kev ua liaj ua teb.

    Hauv cov ntsiab lus, thaum nws los txog xaiv cov yeeb nkab zoo tshaj plawsrau cov kab hauv av, kauv submerged arc welded steel yeeb nkab yog qhov kev xaiv zoo tshaj plaws.Nws cov kauv-welded kev tsim kho muab lub zog, durability thiab corrosion kuj xav tau rau kev ua haujlwm ntev, thaum nws yooj yim thiab siv tau zoo ua rau nws muaj kev xaiv zoo rau cov kav dej ntawm txhua qhov ntau thiab tsawg.Los ntawm kev xaiv kauv submerged arc welded steel yeeb nkab, koj tuaj yeem ua kom muaj kev ntseeg siab thiab ua haujlwm ntev ntawm koj cov kab dej hauv av, muab kev thaj yeeb rau koj lub siab thiab kev ntseeg siab hauv koj lub cev dej.
