Kev teeb tsa thiab kev siv cov kav hlau txuas txuas txuas nrog cov txheej txheem nruj uas yuav tsum tau ua raws li cov xwm txheej tiag tiag thiab cov txheej txheem ua haujlwm kom ntseeg tau zoo. Thaum lub sij hawm siv dav dav ntawm kauv steel kav, kev saib xyuas yuav tsum tau them rau cov ntsiab lus hauv qab no:
Lub installation ntawm kauv steel kav yuav tsum tau nqa tawm raws li tus tsim drawings. Kev txhawb nqa yeeb nkab yuav tsum tau prefabricated raws li qhov chaw nyob, ua raws li kev xuas nrig ntaus thiab shearing raws li tus qauv tsim thiab qhov chaw. Tom qab ntawd, siv lub tshuab polishing los txhuam cov grooves ua ntej pib nrog vuam. Cov kev xav tau zoo rau kev teeb tsa muaj xws li kom ntseeg tau tias qhov sib txawv rau kev teeb tsa ntsug ntawm cov risers tsawg dua 3 hli ib meter, thiab qhov sib txawv rau kab rov tav installation yog tsawg dua 1 hli. Ceg kav yuav tsum tsis txhob welded ntawm weld seams, thiab vuam yuav tsum tau zam ntawm khoov.
Ua ntej siv kauv steel kav, kev tsim kho kom zoo yog qhov tseem ceeb. Xyuas kom meej tias cov yeeb nkab trenches tau khawb, cov yeeb nkab shafts yog tsim, thiab tag nrho cov tsim nyog kauv steel kav thiab cov cuab yeej, xws li vuam tshuab, txiav tshuab, hluav taws xob hammers, polishing tshuab, thiab lwm yam, yog npaj txhij. Tsuas yog tom qab ua tiav cov kauj ruam npaj no tuaj yeem pib installation.
Hais txog kev puas tsuaj rau saum npoo, txoj kev kho ntawm kev ntxiv lub tes tsho yog feem ntau xaiv. Lub tes tsho muaj ob qhov chaw, nrog ob qhov ntev welds tsim los ntawm vuam ob lub strips siv pob tw vuam. Qhov zoo ntawm txoj kev no yog tias tsis muaj welds ntawm lub cev ntawm cov yeeb nkab steel. Lub seam ntev yog lub pob tw weld nrog lub nraub qaum phaj, thiab cov yeeb nkab lub cev nws tus kheej ua lub phaj nraub qaum rau lub tes tsho sab sauv thiab qis. Txawm li cas los xij xaiv txoj kev, lub tes tsho yuav tsum nruj nruj nyob ib ncig ntawm cov yeeb nkab steel.
Vuam yuav tsum ncaj, nrog cov welds tiav, thiab qhov chaw vuam yuav tsum tsis txhob hlawv-dhau thiab tawg. Thaum khawb tsis ua rau cov pa tawm, ob lub voj voos fillet welds ntawm lub tes tsho thiab cov yeeb nkab steel lub cev tsis tas yuav tsum tau welded. Txawm li cas los xij, yog tias cov dej xau tshwm sim, cov welds yuav tsum tau ua. Hauv qhov xwm txheej no, lub tes tsho bears lub siab sab hauv tsim los ntawm cov kua nws muaj. Yog li ntawd, nyob rau hauv xws li mob, lub thickness ntawm lub tes tsho feem ntau yuav tsum tsis muaj tsawg tshaj li ntawm cov yeeb nkab phab ntsa.
