Peb cov kav dej kauv welded muaj nyob rau hauv ntau qhov ntau thiab tsawg, nrog cov diameters xws liΦ219mm uaΦ3500 hli.Tsis tas li ntawd, lawv tau tsim nrog phab ntsa tuab ntawm 6 hli txog 25.4 hli, kom ntseeg tau tias lawv tsim nyog rau ntau yam kev siv.Cov kav dej yog tsim los siv cov txheej txheem submerged arc vuam, uas ua kom muaj zog thiab zoo sib koom ua ke.Cov txheej txheem vuam no ua kom peb cov kav dej tuaj yeem tiv taus qhov chaw muaj kev kub ntxhov, ua rau lawv zoo tagnrho rau kev thauj cov roj thiab roj.
Ib qho ntawm cov txiaj ntsig tseem ceeb ntawm peb cov kav welded steel kav yog lawv ntau yam.Lawv tuaj yeem siv rau hauvcov kav dej hauv tsevtxhawm rau ua kom muaj txiaj ntsig zoo thiab txhim khu kev xa dej hauv cov tsev nyob thiab kev lag luam.Cov kav dej no tseem tuaj yeem siv los txuas cov kav hlau dub, muab kev daws teeb meem zoo thiab raug nqi rau ntau yam kev siv hauv kev lag luam.
Tsis tas li ntawd, peb cov kauv welded steel kav ua tau zoo nyob rau hauv daim ntawv thov steel yeeb nkab.Cov kav dej no yog lub hauv paus ruaj khov rau cov qauv xws li txuas hniav, txhawb nqa cov khoom tseem ceeb thiab muab kev ntseeg tau ntev.Lawv cov qauv tsim kom muaj zog thiab ruaj khov, ua kom muaj kev nyab xeeb thiab ruaj khov ntawm cov qauv zoo li no.
Ntxiv nrog rau kev ua tau zoo heev, peb cov kav dej welded tau txais txiaj ntsig los ntawm kev ua haujlwm zoo los tiv thaiv corrosion thiab thermal rwb thaiv tsev txheej.Anti-corrosion txheej tiv thaiv xeb thiab corrosion, ncua lub neej ntawm koj cov kav dej.Thermal barrier coatings pab tswj qhov kub thiab txias ntawm cov kua yuav tsum tau thauj, txo cov cua sov los yog kub nce.
Ntawm Cangzhou Spiral Steel Pipe Group Co., Ltd., peb muab qhov tseem ceeb rau cov neeg siv khoom txaus siab thiab siv zog ua kom tau raws li cov qauv kev lag luam siab tshaj plaws.Peb cov kav welded kav tau txais kev tswj xyuas nruj kom ntseeg tau tias lawv ua tau raws li peb cov neeg siv khoom tshwj xeeb.Peb tau cog lus los muab cov khoom lag luam txhim khu kev qha, ruaj khov thiab ua tau zoo kom tau raws li qhov xav tau ntawm ntau yam kev siv.
Xaiv peb cov kauv welded steel kav rau koj qhov project tom ntej thiab paub txog qhov kev ua tau zoo tshaj plaws thiab ntau yam uas lawv muaj.Nrog rau peb cov chaw tsim khoom hauv lub xeev thiab kev cog lus rau cov neeg siv khoom txaus siab, peb lav cov khoom lag luam txhim khu kev qha, ua tau raws li koj cov kev xav tau tshwj xeeb.Cia siab rau peb cov kev paub dhau los, ntseeg peb cov khoom, thiab ua rau peb tus neeg muag khoom nyiam rau txhua yam koj xav tau ntawm cov kav hlau welded.
