Tuam txhab tau zoo dua

Peb lub Hoobkas nyob hauv Cangzhou, Hebei xeev, thiab peb tau dhau los ntawm kev tsim khoom zoo steel 680 lab, tuaj yeem tsim 400,000 tons ntawm KAUV STEEL PIPES ib xyoos, thiab muaj 680 tus kws tshaj lij.

Khoom Taw Qhia

Peb txoj kev cog lus rau kev ua kom zoo tshaj plaws yog xav txog hauv peb cov kev tsis txaus ntseeg arc vuam, uas yog ib qib tseem ceeb hauv kev tsim khoom ntawm peb cov khaub ncaws welded yeeb nkab. Cov tshuab no siv qhov kub siab los tsim cov kav dej muaj zog thiab ruaj khov uas peb cov khoom muaj peev xwm txhim khu kev qha txawm tias nyob hauv ib puag ncig nyuaj tshaj plaws. Txawm hais tias koj nyob hauv cov roj cua kev lag luam lossis xav tau kev daws teeb meem kev daws teeb meem rau lwm cov kev siv, peb cov kav dej yuav ntsib thiab tshaj qhov koj xav tau.

Nrog rau kev tsom mus rau qhov zoo thiab kev tsim kho tshiab, peb muaj peb tus kheej ntawm kev muab cov ntaub qhwv cov yeeb nkab uas lav tau ntev ntev. Tsis yog pebMuab kauv welded yeeb nkabMuaj zog thiab ruaj, lawv tseem muaj txiaj ntsig zoo heev, ua rau lawv zoo tshaj plaws rau cov phiaj xwm uas yuav tsum muaj kev ntseeg siab thiab kav ntev.

Lub ntsiab tseem ceeb

Ib qho ntawm cov yam ntxwv tseem ceeb ntawm kev vuam raj yog nws qhov kev tso siab ntawm arc vuam, cov txheej txheem uas siv cov kev sib txuas ntau, ruaj khov ntawm cov leeg hlau. Cov txheej txheem yog qhov tseem ceeb los txhawm rau ua kom muaj kev ncaj ncees thiab kev ntseeg tau ntawm cov khoom kawg, tshwj xeeb hauv cov ntawv thov kev nyab xeeb, xws li cov roj thauj.

Cov txheej txheem arc vuam cuam tshuam txog cov yeeb nkab ntawm cov yeeb nkab thiab finging lawv ua ke, tsim kom muaj kev sib txuas ntawm lub siab thiab siab. Txoj kev no tsis yog nce lub zog ntawm cov yeeb nkab, tab sis kuj txuas nws txoj kev pabcuam lub neej, ua rau nws txoj kev xaiv uas nyiam dua rau ntau yam kev siv khoom.

Ib qho ntxiv, cov qauv ntsuas thiab cov kev txawj xav rau cov vuam vuam kuj tseem pom lub tuam txhab kev cog lus kom zoo. Los ntawm kev nqis peev hauv cov thev naus laus zis thiab cov khoom ua haujlwm tshaj lij, lub cangzhou cog kom zoo rau cov qauv kev lag luam nruj, muab cov neeg siv kev thaj yeeb nyab xeeb ntawm cov khoom lag luam.

Cov khoom kom zoo dua

Ib qho ntawm qhov tseem ceeb ntawm kev siv raj vuam yog nws lub peev xwm los tsim cov pob qij txha muaj zog uas tuaj yeem tiv thaiv qhov siab siab thiab cov mob siab. Qhov no yog qhov tshwj xeeb tshaj yog hauv kev lag luam roj ntuj, qhov uas cov raj xa hluav taws xob ntawm cov raj xa dej yog qhov tseem ceeb. Cov txheej txheem arc vuam ua kom ntseeg tau tias covTube Weldyog tsis tsuas yog muaj zog tab sis kuj zoo ib yam, uas txo qhov kev pheej hmoo ntawm txeej thiab ua tsis tiav. Tsis tas li ntawd, kev ua tau zoo ntawm cov raj vuam tso cai rau cov tuam txhab kom nrawm rau cov khoom siv loj ntawm cov khoom lag luam kom loj hlob.

Khoom tsis txaus

Cov txheej txheem yuav tsum muaj cov neeg ua haujlwm txawj ntse thiab tswj kev sib tw ntawm vuam tsis muaj qhov tsis xws luag xws li porosity lossis tsis muaj fusion. Cov teeb meem no tuaj yeem cuam tshuam qhov zoo ntawm cov khoom kawg thiab ua rau muaj kev phom sij kev nyab xeeb.

Tsis tas li ntawd, qhov kub ntawm arc vuam tuaj yeem qhia cov kev ntxhov siab tseem ceeb hauv cov khoom siv tau ntev ntawm cov raj xa dej.

Cov Lus Nug

Q1: Dab tsi yog arc vuam?

Arc Vuam yog cov txheej txheem uas siv cov kub siab tsim los ntawm ib qho hluav taws xob arc kom yaj thiab cov hlau sib dhos ua ke. Rau cov yeeb nkab kauv welded, cov qauv no yog qhov tseem ceeb los tsim kev sib txuas muaj zog ntawm cov kav dej, uas yog qhov tseem ceeb rau kev ua yeeb yam thiab lub neej ntawm cov yeeb nkab.

Q2: Vim li cas Arc vuam tseem ceeb rau cov roj nkev?

Natural Gas Pipelines yuav tsum ntsib txoj kev nyab xeeb thiab kev ntseeg siab. Cov txheej txheem arc vuam kom ntseeg tau tias Weld pob qij txha tuaj yeem tiv thaiv cov kev ntsuas siab thiab tiv taus kev thauj khoom, ua kom zoo rau thauj cov pa roj ntev dhau mus deb.

Q3: Koj lub tuam txhab nyob qhov twg?

Peb lub Hoobkas nyob hauv Cangzhou, Hebei xeev, thaj chaw paub rau nws muaj zog muaj zog. Peb lub tuam txhab tau tsim nyob rau hauv 1993 thiab tau loj hlob los npog thaj tsam ntawm 350,000 square metres thiab ntiav 680 cov neeg tau mob siab rau.
