Ib qho ntawm qhov tseem ceeb tshaj plaws ntawmkauv welded tubeyog nws lub zog superior, uas tshaj qhov ncaj seam welded yeeb nkab.Qhov no ua rau nws zoo tagnrho rau tej yaam num uas xav tau kev txhim kho kev ncaj ncees.Tsis tas li ntawd, vim nws cov txheej txheem tsim tshwj xeeb, kauv welded yeeb nkab tuaj yeem tsim tau siv cov hlau nqaim, tso cai rau kev tsim cov kav dej loj dua.Tsis tas li ntawd, los ntawm kev siv cov blanks ntawm tib qhov dav, peb tuaj yeem siv zog ua cov raj ntawm cov kab sib txawv, ntxiv rau nws qhov ntau yam.
Nrog rau kev cog lus ruaj khov rau kev ua tau zoo, peb lub tuam txhab tau nqis peev tseem ceeb hauv kev teeb tsa cov chaw tsim khoom hauv lub xeev.Lub tuam txhab npog thaj tsam ntawm 350,000 square meters thiab muaj tag nrho cov cuab tam ntawm 680 lab yuan.Tab sis qhov tiag ua rau peb sib cais yog peb pab neeg mob siab rau.Peb cov neeg ua haujlwm ntawm 680 tus kws tshaj lij tshaj lij yog lub zog tsav tom qab peb txoj kev vam meej.
Peb txaus siab rau peb lub peev xwm tsim khoom txhua xyoo ntawm 400,000 tons ntawm kauv steel hlab, tshaj li cov qauv kev lag luam.Qhov no unparalleled tso zis tau tsim ib tug tsis tshua muaj siab tso zis nqi ntawm 1.8 billion yuan.Peb pab neeg mob siab ua kom ntseeg tau tias txhua lub cuab yeej tawm hauv peb lub chaw ua raws li kev tswj hwm nruj tshaj plaws, lav peb cov neeg siv khoom zoo dua.
Hauv cov ntsiab lus, kauv submerged arc welded kav yog ib qho kev ua si hloov pauv rau kev lag luam yeeb nkab steel.Nrog nws lub zog zoo dua, kev ua tau zoo tshaj plaws thiab kev ntseeg siab tsis sib xws, nws yog qhov kev daws teeb meem zoo tshaj plaws rau tag nrho koj cov yeeb nkab welded.Koom tes nrog Cangzhou Spiral Steel Pipes Group Co., Ltd. hnub no kom paub txog yav tom ntej ntawm kev lag luam steel yeeb nkab.
