Ua ntej yuav khoomLoj-inch ncaj seam steel kav (LSAW), koj yuav tsum ua raws li cov qauv tsim ua ntej, qhov ntev, cov ntaub ntawv, phab ntsa thicknesses, vuam cov qauv thiab cov khoom siv vuam, uas yuav tsum tau sib txuas lus zoo ua ntej yuav khoom.

1. Thawj yog qhov specification.Piv txwv li, 800mm kuj tseem hu ua DN800, suav nrog 820mm thiab 813mm ntawm A thiab B series, los yog sab nraud txoj kab uas hla ntawm 800mm yuav tsum tau kom meej meej kom tsis txhob poob qhov tsis tsim nyog.

2. Cov phab ntsa tuab ntawm qhov loj-inch ncaj seam steel yeeb nkab yuav tsum yog 16 hli.Nws yog qhov ua tau tias qhov tseeb thickness ntawm cov ntaub ntawv raw yuav yog 15.75mm thiab 16.2mm, thiab yuav muaj qhov sib txawv sab sauv lossis qis dua.Cov no yog ib txwm deviations.Vim hais tias ncaj seam steel kav yog tag nrho cov nqi tuj, nws yuav tsum tau sib txuas lus ua ntej kom tsis txhob muaj qhov sib txawv ntawm qhov hnyav.

3. Qhov ntev ntev ntawm qhov loj-inch ncaj seam steel yeeb nkab yog 12m.Thaum nws yuav tsum tau kho, nws yuav tsum tau sib txuas lus ua ntej, vim hais tias tus nqi ntawm qhov ntev ruaj yuav kim dua.Yog tias tsis sib txuas lus ua ntej, nws yuav ntev 9.87m, thiab cov chaw tsim khoom feem ntau muab 9.9m ncaj qha.
4. Cov ntaub ntawv rau kev yuav khoom loj-ntev ncaj seam steel kav yuav tsum tau sib txuas lus zoo, thiab cov ntaub ntawv yuav tsum tsis txhob OEM.Tsis tas li ntawd, cov ntaub ntawv yuav tsum tau lav, thiab cov ntaub ntawv tseem ceeb ntawm cov hlau zeb yuav tsum tau muab.Txhua yam teeb meem khoom siv yuav raug xa rov qab thiab them nyiaj rov qab.

5. Cov txheej txheem vuam rau kev tsim khoom thiab kev ua haujlwm yuav tsum ua raws li qhov tsis siv neeg submerged arc vuam LSAW GB / T3091-2015, thiab yuav tsum muaj daim ntawv pov thawj khoom zoo.Yog tias tus qauv tsis ua raws li qhov yuav tsum tau ua, cov khoom ua tsis tiav.
6. Thaum yuav khoom loj-ntev ncaj seam steel kav, nws yuav tsum tau sib txuas lus ua ntej txog qib ntawm weld flaw detection, vim weld flaw detection yuav raug nqi nyiaj ntxiv.teeb meem.
7. Tsis tas li ntawd, qhov loj-inch ncaj seam steel kav saum toj 1020mm yuav tsim tau ob lub welds.Ntau qhov haujlwm yuav tsis lees txais ob lub vuam yam tsis muaj kev sib txuas lus ua ntej, thiab yuav raug hu ua cov kav hlau tsis zoo.

Yog li ntawd, nws yog ib qho tsim nyog yuav tsum tau sib txuas lus zoo ua ntej ua ntej yuav cov yeeb nkab steel, ua rau muaj kev tsis sib haum xeeb thiab kev poob nyiaj txiag.
