Nyob rau hauv kev faib tawm ntawm welded steel kav, ERW steel kav thiab EFW steel kav sawv cev rau ob hom khoom uas tsis tshua muaj siab tsis meej. Txawm hais tias ob qho tib si yog longitudinally welded steel kav, lawv txawv heev nyob rau hauv vuam cov hauv paus ntsiab lus, manufacturing txheej txheem, siv ntau yam, thiab kev ua haujlwm tseem ceeb. Kev nkag siab zoo ntawm cov kev sib txawv no ua rau muaj kev xaiv tsim nyog ntau dua hauv cov ntawv thov engineering.
I. Qhov txawv ntawm Vuam Cov Cai
1. Vuam txoj kev rau ERW Steel Pipes
ERW steel kav siv hluav taws xob tiv thaiv vuam. Cov txheej txheem no siv cov hluav taws xob tiv thaiv hluav taws xob thaum muaj siab - zaus tam sim no dhau los ntawm cov npoo ntawm cov hlau strips, ua kom sov cov khoom mus rau lub xeev yas. Nyob rau hauv lub siab ntawm nyem rollers, qhov no ua tiav ib daim ntawv cog lus metallurgical. Tsis tas yuav tsum muaj cov khoom muab tub lim thaum vuam; lub weld seam feem ntau tsim los ntawm fusion ntawm lub hauv paus hlau nws tus kheej.
Txoj kev vuam no ua rau muaj cua sov me me- thaj tsam cuam tshuam thiab muaj kev vuam nrawm, ua rau nws tsim nyog rau kev ua haujlwm tas mus li, loj - nplai ntau lawm.
2. Vuam txoj kev rau EFW Steel Pipes
EFW steel kav siv cov txheej txheem hluav taws xob fusion vuam. Thaum lub sij hawm vuam, cov npoo ntawm cov hlau phaj yog yaj los ntawm ib qho hluav taws xob arc lossis hluav taws xob fusion txoj kev, nrog cov xaim muab tub lim qhia los tsim cov vuam. Cov txheej txheem no suav nrog cov khoom siv hluav taws xob ntau dua, thiab kev tsim cov vuam yog nyob ntawm kev tswj lub pas dej ua ke.
Kev siv cov khoom muab tub lim muab EFW steel kav nrog qhov yooj yim hauv kev kho cov khoom siv vuam thiab tswj lub zog vuam.
II. Qhov sib txawv ntawm cov khoom siv raw thiab cov txheej txheem tsim
1. Raw Khoom yam ntxwv ntawmERW steel yeeb nkab
ERW steel kav feem ntau siv kub- dov steel coils ua raw khoom. Cov coils no txuas ntxiv khoov mus rau hauv cov raj ncig ntawm cov kab txuas txuas ntxiv ua ntej yuav ua rau siab - zaus vuam. Txoj kev tsim khoom no yog qhov zoo- haum rau kev tsim cov khoom me me - mus rau - nruab nrab txoj kab uas hla, muab cov khoom siv siab.
2. Raw Khoom yam ntxwv ntawm EFW Steel Pipes
EFW steel kav feem ntau siv nruab nrab - mus rau - cov phaj tuab. Cov no yog tsim los ntawm cov phaj dov ua ntej yuav raug hluav taws xob tiv thaiv fusion vuam. Muab piv rau cov coil-raws li cov ntaub ntawv, phaj thickness muaj qhov yooj yim dua, ua EFW steel kav tshwj xeeb tshaj yog tsim rau kev tsim nruab nrab- mus rau - txoj kab uas hla loj, tuab - cov kav dej welded.
III. Qhov sib txawv hauv Cov Kev Qhia Tshwj Xeeb Muaj
ERW steel kav feem ntau yog ua haujlwm nyob rau hauv me me - mus rau - nruab nrab txoj kab uas hla thiab nruab nrab - phab ntsa thickness ranges. Lawv tau zoo- haum rau cov qauv tsim, batch ntau lawm thiab pom cov ntawv thov dav dav hauv cov kav dej thiab cov txheej txheem engineering.
EFW steel kav yog zoo dua haum rau loj diameters los yog tshwj xeeb phab ntsa thickness yuav tsum, qhia tshwj xeeb zoo nyob rau hauv heev customized tej yaam num nrog tshwj xeeb weld qauv xav tau.
IV. Qhov sib txawv ntawm Weld Performance and Quality Control
1. ERW steel yeeb nkabWeld yam ntxwv
ERW steel yeeb nkab welds nthuav tawm kev faib tawm. Ua raws li hauv - kab deburring thiab cov txheej txheem kho cua sov, thaj tsam weld ua tiav cov khoom zoo ib yam nrog cov khoom siv hauv paus. Lub weld microstructure yog zoo-grained nrog zoo tag nrho cov uniformity, ua rau nws haum rau daim ntaub ntawv thov qhov siab qhov tseeb thiab zoo nkauj tsos.
2. EFW Steel Yeeb Nkab Weld Yam ntxwv
EFW steel yeeb nkab welds yog tso welds, featuring ib tug txawv fusion cheeb tsam ntawm lub weld hlau thiab cov khoom siv. Weld thickness thiab profile tuaj yeem tswj tau los ntawm kev siv vuam, ua rau lawv tsim nyog rau cov ntawv thov kom muaj zog dua weld thiab tuab - cov qauv phab ntsa.
V. Kev Ua Tau Zoo Tshaj Plaws thiab Tus Nqi Sib Piv
ERW steel yeeb nkab ntau lawm muaj kev nrawm nrawm thiab siab automation, ua rau cov nqi qis dua. Nws yog qhov zoo - haum rau kev yuav khoom ntau thiab cov txheej txheem engineering, nthuav qhia cov nqi tswj tau zoo.
EFW steel yeeb nkab vuam txheej txheem yog qhov sib piv, nrog kev ua haujlwm qis dua thiab kev xav tau ntau dua ntawm cov txheej txheem vuam thiab kev ua haujlwm zoo. Yog li ntawd, tag nrho cov nqi tsim khoom feem ntau yog siab dua rau cov kav dej ERW, txawm tias lawv tuaj yeem ua tau raws li qib siab dua - qib lossis cov ntawv thov tshwj xeeb.
VI. Qhov sib txawv ntawm Daim Ntawv Thov Kev Pom Zoo
ERW steel kav yog siv dav hauv nruab nrab - mus rau - tsis tshua muaj siab thiab dav siv engineering xws li cov kav dej hauv nroog thiab cov kav dej, cov kav dej, cov khoom siv hauv tsev, kev tiv thaiv hluav taws, thiab kev tsim khoom siv tshuab.
EFW steel kav feem ntau ua haujlwm hauv kev tsim hluav taws xob, kev txhawb nqa lub nkoj siab, loj - txoj kab uas hla, cov ntawv thov thauj tshwj xeeb, thiab cov chaw lag luam uas xav tau kev ua haujlwm zoo dua weld seam.
Xaus
Hauv cov ntsiab lus, thaum ob qho tib si ERW thiab EFW steel kav poob rau hauv qeb ntawm longitudinally welded steel kav, lawv txhua tus muaj qhov zoo sib xws ntawm cov txheej txheem vuam, xaiv cov khoom siv raw, cov khoom tshwj xeeb, thiab daim ntawv thov tsom. ERW steel kav ua tau zoo tshaj plaws hauv kev ua haujlwm thiab tus nqi-kev ua tau zoo, ua rau lawv tsim nyog rau cov qauv siv thiab loj- nplai. EFW steel kav qhia tau hais tias muaj kev hloov pauv tau zoo nyob rau hauv loj - txoj kab uas hla, tuab - phab ntsa, thiab siab - xav tau qhov xwm txheej. Thaum xaiv qhov ua tau zoo, kev txiav txim siab dav dav yuav tsum tau muab rau qhov kev ntsuas siab, cov kev xav tau tshwj xeeb, cov qauv zoo, thiab kev txwv nyiaj txiag los txiav txim siab cov khoom siv yeeb nkab uas tsim nyog tshaj plaws.
