    Hydrostatic Test

    khoom-description1

    Cov yeeb nkab yuav tsum tiv taus qhov kev sim hydrostatic yam tsis muaj qhov xau los ntawm cov vuam seam lossis lub cev yeeb nkab
    Jointers yuav tsum tsis txhob sim hydrostatically, yog hais tias cov feem ntawm cov yeeb nkab siv nyob rau hauv kos cov jointers tau ua tiav hydrostatically kuaj ua ntej kev koom tes ua hauj lwm.

    Helical Submerged Arc Vuam

    Ua ntej, ob chav submerged arc vuam yog ib txoj hauv kev zoo thiab kev lag luam ntawm kev koom nrog cov kav dej.Cov txheej txheem cuam tshuam nrog kev tsim cov vuam los ntawm dipping cov yeeb nkab rau hauv cov dej ntws siv ob lub vuam arcs.Qhov no ua rau muaj zog thiab ruaj khov weld uas tuaj yeem tiv taus siab thiab nro, ua rau nws zoo tagnrho rau cov roj thiab dej.

    Ib qho ntawm qhov zoo ntawm ob chav submerged arc welded yeeb nkab yog nws cov corrosion kuj.Cov kua dej granular siv nyob rau hauv cov txheej txheem vuam no tsim cov txheej txheem tiv thaiv tshaj qhov vuam, pab tiv thaiv corrosion thiab ncua lub neej ntawm cov yeeb nkab.Qhov no yog qhov tseem ceeb tshwj xeeb raudej kab tubing, raws li nws xyuas kom meej tias cov dej xa tawm tseem huv thiab tsis muaj kab mob.

    Ntxiv nrog rau kev tiv thaiv corrosion, ob chav submerged arc welded kav muaj cov khoom siv zoo heev.Txoj kev no tsim cov welds tsis sib xws thiab cov yeeb nkab muaj zog thiab txhim khu kev qha.Qhov no yog qhov tseem ceeb rau cov kav xa hluav taws xob zoo li nws ua kom muaj kev nyab xeeb thiab muaj txiaj ntsig kev thauj mus los ntawm cov pa roj yam tsis muaj kev pheej hmoo ntawm kev xau lossis tsis ua haujlwm.

    SSAW Tube

    Tsis tas li ntawd, ob chav submerged arc welded kav muaj peev xwm tiv taus qhov kub thiab txias ib puag ncig.Qhov no ua rau lawv zoo tagnrho rau kev siv sab nrauv thiab sab nrauv uas yuav raug rau huab cua hnyav thiab kev ua haujlwm.Rau cov kav dej, qhov kav ntev no ua kom cov kav dej tuaj yeem txav tau dej zoo yam tsis muaj kev cuam tshuam kev ua haujlwm.

    Lwm qhov zoo ntawm kev siv ob chav submerged arc welded yeeb nkab yog tias nws qhov chaw yog du thiab zoo nkauj.Qhov no ua rau lawv muaj kev xaiv zoo rau saum toj- thiab hauv qab-hauv av installation, vim lawv yooj yim los xyuas thiab tswj.Tsis tas li ntawd, qhov du nto ntawm weld txo qhov kev sib txhuam thiab kev poob siab hauv cov yeeb nkab, pab txhim kho tag nrho cov kev ua tau zoo ntawm cov roj thiab dej xa khoom.

    Hauv kev xaus, ob chav submerged arc welded yeeb nkab yog qhov kev xaiv zoo heev raugas kabthiab cov kav dej.Nws cov txheej txheem vuam tau zoo thiab raug nqi, ua ke nrog kev tiv thaiv corrosion, cov khoom siv zoo heev, ua haujlwm ntev thiab zoo nkauj, ua rau nws yog thawj qhov kev xaiv rau kev tsim cov kav dej.Txawm tias thauj cov roj av lossis dej, cov kav dej no muab lub zog thiab kev ntseeg siab uas yuav tsum tau ua kom muaj kev nyab xeeb thiab ua haujlwm tau zoo.Kom meej meej, ob-txheej submerged arc welded yeeb nkab yog ib qho khoom muaj nqis nyob rau hauv lub ntiaj teb kev tsim cov kav dej.
