Khoom Taw Qhia
Peb cov khoom lag luam tshiab tau sib koom ua ke txuas ntxiv, ua los ntawm cov hlau zoo steel ib daim uas tau muab tso tawm ntawm cov ntsuj plig. Txoj kev tsim tshwj xeeb no tsis tsuas yog nce cov yeeb nkab ntawm cov yeeb nkab, tab sis kuj muab lub zog tsis muaj zog, ua rau nws zoo rau cov roj av roj av thiab lwm yam tseem ceeb.
Peb cov kauv Welded Steel kav yog engineered kom withstand high ntsuas thiab huab kev mob, ua kom muaj kev nyab xeeb thiab txhim kho cov roj teeb ntuj. Peb nkag siab qhov tseem ceeb ntawm kev saib xyuas kev ncaj ncees ntawm cov roj nkev, thiab peb cov khoom lag luam muaj cov qauv kev lag luam thiab cov cai.
Thaum koj xaiv pebMuab kauv welded steel yeeb nkab, koj nqis peev pab rau kev daws teeb meem uas muaj kev nyab xeeb yam tsis muaj kev ua tau zoo. Txawm hais tias koj ua haujlwm hauv kev lag luam hluav taws xob, kev tsim kho, lossis ib qho kev lag luam uas xav tau cov kev daws teeb meem piping, peb muaj cov khoom kom tau raws li koj cov kev xav tau.
Tuam txhab tau zoo dua
Nyob hauv plawv plawv ntawm Cangzhou City, Hebei lub xeev, peb lub Hoobkas tau muab cov tshuab yeeb nkab ntawm xyoo 1993. Nrog rau tag nrho cov khoom muaj nqis ntawm RMB 680 lab thiab 680 tus neeg ua haujlwm tau mob siab, peb tau cog lus los muab cov khoom lag luam uas yuav tsum tau ua raws li peb cov neeg siv khoom.
Cov khoom kom zoo dua
Cov roj pipes tsim tawm ntawm cov nroj tsuag tshwj xeeb txuas cov pob qij txha sib txuas, ua los ntawm cov ntsuj plig welded steel ib daim. Qhov kev tsim qauv no muaj qhov tsis muaj zog, ua cov kav dej zoo tshaj plaws rau cov ntawv thov uas muaj ntuj hloov. Kev tsim kho kom ruaj khov ua kom cov kav dej tuaj yeem tiv thaiv qhov siab thiab cov kev mob siab ib puag ncig, uas yog qhov ua tau zoo ntawm cov roj thauj khoom.
Ntawm qhov zoo sab, lub zog thiab lub zog ntawm cov kav dej no txhais tau tias lawv muaj lub neej ntev thiab tsis tas yuav hloov cov nqi txij nkawm ntev, thaum kawg txo cov nqi kho mob.
Tsis tas li ntawd, lawv tiv taus rau corrosion thiab lwm txoj kev ib puag ncig, ua rau lawv xaiv txoj kev ntseeg tau rau kev siv ntev.
Khoom tsis txaus
Ntawm downside, thawj tus nqi ntawm kev ua tau zooRoj KavYuav muaj siab, uas yuav tiv thaiv qee cov tuam txhab los ntawm kev nqis peev.
Ib qho ntxiv, cov txheej txheem teeb tsa tuaj yeem nyuaj thiab yuav tsum tau ua haujlwm txawj, uas tuaj yeem nce cov kev siv nyiaj ntau.
Cov nyhuv tseem ceeb
Ib qho ntawm cov nroj tsuag cov khoom standout yog nws cov cuab yeej txuas ntxiv hloov cov roj. Ua kom siv cov txheej txheem meticly ntawm kev sib tw steel ib daim, cov kav dej no muaj cov qauv tshwj xeeb uas muaj lub zog tsis sib xws. Qhov kev tsim qauv no tshwj xeeb yog tsim tshwj xeeb rau cov ntawv thov nkag mus, xws li nkev roj, qhov twg ruaj khov thiab ntseeg tau.
Lub hom phiaj tseem ceeb ntawm cov raj roj hauv roj yog los tiv thaiv qhov siab uas siab kom ntseeg tau tias muaj kev nyab xeeb ntawm cov nkev. Muab kauv vuam siv tsis tsuas yog txhim kho cov txheej txheem kev ntseeg siab ntawm cov raj xa dej, tab sis kuj tseem muab kev tsim kom tsim, ua rau nws haum rau ntau yam kev teeb tsa kev teeb tsa. Qhov no yog qhov tseem ceeb rau kev lag luam uas muaj kev nyab xeeb thiab ua haujlwm yog qhov tseem ceeb tshaj plaws.
Raws li qhov kev thov rau cov nkev nce ntxiv, lub luag haujlwm ntawm cov pipel gan-roj zoo tau ua ib qho tseem ceeb ntxiv. Advanced tsim cov cuab yeej ua ke nrog kev cog lus rau qhov zoo tau ua qhov no cangzhou-based tuam txhab tus neeg ua haujlwm tseem ceeb hauv lub zog.
