    Automated Yeeb Nkab Vuam

    Tuam txhab Advantage

    Nyob rau hauv plawv ntawm Cangzhou City, Hebei xeev, lub tuam txhab tau ua ib tug thawj coj nyob rau hauv welded yeeb nkab manufacturing txij li thaum nws nrhiav tau nyob rau hauv 1993. Cov nroj tsuag npog thaj tsam ntawm 350,000 square meters thiab yog txawm peem rau nrog advanced machinery thiab technology los tsim thawj- cov khoom lag luam uas ua tau raws li cov qauv thoob ntiaj teb. Nrog rau tag nrho cov khoom muaj nqis ntawm RMB 680 lab thiab 680 tus neeg ua haujlwm txawj, lub tuam txhab tau cog lus rau kev ua tau zoo hauv txhua yam ntawm nws cov haujlwm.

    Khoom Taw Qhia

    Qhia peb cov txheej txheem tshwj xeeb tshaj plaws ntawm cov yeeb nkab vuam tshuab, tsim tshwj xeeb kom ua tau raws li qhov xav tau ntawm arc vuam cov raj xa hluav taws xob. Nyob rau hauv lub forefront ntawm no innovation yog peb advanced Submerged Arc Vuam tshuab (SAW), txoj kev nyiam rau spirally welded yeeb nkab.

    FAQ

    Q1. Submerged Arc Welding (SAW) yog dab tsi?

    SAW yog txheej txheem vuam uas siv cov khoom siv hluav taws xob tsis tu ncua thiab txheej txheej ntawm granular fusible flux los tiv thaiv cov vuam los ntawm kev sib kis. Txoj kev no tshwj xeeb tshaj yog siv rau cov ntaub ntawv tuab thiab zoo haum rau cov kav dej ntuj.

    Q2. Yog vim li cas SAW nyiam rau kauv welded kav?

    SAW thev naus laus zis muab kev nkag mus tob thiab qhov chaw du, uas yog qhov tseem ceeb rau kev ua haujlwm ntawm kev ncaj ncees.kauv welded yeeb nkabsiv nyob rau hauv high-pressure daim ntaub ntawv xws li natural gas tsheb thauj mus los.

    Q3. Dab tsi yog cov txiaj ntsig ntawm kev siv cov yeeb nkab vuam tshuab?

    Cov txheej txheem tshwj xeeb ntawm lub raj vuam ua kom zoo ib yam, txo qhov kev pheej hmoo ntawm qhov tsis xws luag thiab txhim kho tag nrho cov khoom siv welded, uas yog qhov tseem ceeb hauv kev lag luam kev nyab xeeb.

    Q4. Koj lub tuam txhab ua li cas thiaj li ua tau zoo ntawm cov txheej txheem vuam?

    Peb lub tuam txhab ua raws li kev tswj xyuas nruj nruj thiab ntiav cov kws tshaj lij uas tau kawm hauv cov txheej txheem vuam tshiab, suav nrog SAW, kom ntseeg tau tias txhua yam khoom ua tau raws li cov qauv kev nyab xeeb thiab kev ua tau zoo.
