In recent years, with the continuous development of urban construction and infrastructure improvement, the demand for high - quality drainage pipelines has been on the rise. Muab kauv kav hlau welded tau tshwm sim raws li kev xaiv tsis txhim khu kev qha hauv daim teb no, muab kev sib txuas ua ke zoo uas ua rau lawv sawv.
1. Cov Txheej Txheem Ntau Lawm: Kev Ua Haujlwm Zoo thiab Tus Nqi -} ua hauj lwm zoo
Cov txheej txheem ntau lawm ntawm muab kauv welded kav hlau rau cov ntawv thov kom sib nrug. Pib nrog steel sawb coils, lawv yog thawj ncaj, ua kom ncaj, thiab lawv cov npoo tau npaj. Cov coils tau tsim los ua tus kauv duab los ntawm cov yob ntawm cov chais, thiab welded siv lub tshuab hlau {} {sided submerged arc vuam txheej txheem. Hom qauv no tsis tsuas yog ua kom muaj kev lag luam ntau dua tab sis tseem ua rau tus nqi muaj nqis tsawg. Piv txwv li, piv rau qee cov kav dej uas tsis muaj zog, cov kauj ruam muaj zog thiab tsawg dua rau cov phiaj xwm kev sib xyaw hauv cov dej num.
2. VUAM UA HAUJ LWM: Tus yuam sij rau Kev Tsim Kho Kom Zoo
Vuam yog ib qho tseem ceeb heev ntawm cov kauj ruam tseem ceeb hauv kev tsim cov kauv welded kav dej rau cov kua. Ua ntej vuam, deoxidizers tau siv los txo tus naj npawb thiab loj ntawm impurities nyob rau hauv cov hlau, uas tau txais txiaj ntsig zoo rau qhov zoo ntawm weld. Lub siab - zaus} zaus vuam txheej txheem ntawm muab kauv kav hlau welded siv hluav taws xob hauv hluav taws xob. Raws li cov steel sawb npoo dhau los ntawm qhov siab- zaus induction induction, cua sov cov npoo rau ib lub xeev molten rau vuam.
Qhov kev ruaj ntseg ntawm kev tsim cov txheej txheem thaum lub sij hawm vuam yog ze ze rau cov vuam zoo. A uniform forming gap is essential for ensuring a good - looking weld and sufficient penetration depth. Txawm li cas los xij, vim yog khoov thiab "s {{3} zoo nkauj" deformation ntawm cov hlau stip, cov kev sib tw ntawm cov kev sib tw tsis sib luag, cov kev sib tw ntawm cov nyom. Txhawm rau hais txog qhov no, cov neeg ua haujlwm hloov kho cov vuam specifications raws li qhov xwm txheej ntawm kev tsim Weld. Thaum kev tsim weld yog xoob, qhov kev qhia vuam yog txo; Thaum nws nruj dua, lub vuam vuam yog nce. Qhov kev tswj hwm zoo no pab kom ntseeg tau tias qhov kev ruaj ntseg ntawm weld nkag tob thiab kev sib txig ntawm Weld Bead qhov siab.
3. Daim ntawv thov nyob rau hauv Kev Ua Si Lub Nruab Nrab: Ntau yam thiab dav siv
Muab kauv welded kav tau pom cov ntawv thov uas dav heev hauv ntau yam ntawm cov nqus dej. Hauv nroog dej phwj tuaj pov tseg, lawv feem ntau siv raws li cov kav dej tseem ceeb, muaj peev xwm nrog nrog cov dej phwj tuaj thiab dej khib nyiab. Lawv cov loj {{2} txoj kab uas hla tuaj yeem ntsib lub siab {3} Tse cov chaw ua haujlwm ntawm cov dej phwj tuaj.
Tsis tas li ntawd, hauv kev kho cov nroj tsuag kom muaj dej khib nyiab pov tseg, muab kauv welded kav dej kuj tau siv. Lawv tuaj yeem tiv thaiv kev xeb ntawm qee yam kev muaj dej khib nyiab uas muaj cov tshuaj lom neeg tshuaj, kom ntseeg tau qhov kev thauj khoom nyab xeeb ntawm cov dej tsis huv ntawm kev kho mob. Piv txwv li, hauv cov nroj tsuag tshuaj, cov nroj tsuag hluav taws xob, thiab cov pob zeb mills, muab kauv welded kav ua si lub luag haujlwm tseem ceeb hauv kev sib sau thiab kev thauj mus los ntawm dej ntas.
Ntxiv mus, nyob rau hauv kev tsim kho cua daj cua dub ua rau cov dej ntws tawm, muab kauv welded dej nag los ntawm thaj chaw hauv nroog loj thiab qis ing Lawv lub siab - lub zog thiab txeej}}}}} kev ua haujlwm ntawm kev ua haujlwm cua daj cua dub.
4. Anti {{- Cov Qauv Corrosion: Lub Neej Muaj Peev Xwm
Muab cov kav dej uas tso dej feem ntau tau sib chwv dej thiab ntau cov tshuaj corrosive, anti - corrosion yog ib qho kev txiav txim siab tseem ceeb. Lub isti - corrosion txoj kev rau kauv welded kav welded siv los ntawm inhibitate cov txheej txheem. Ib txoj kev ib txwm yog siv los ntawm - corrosion txheej. Tam sim no, muaj ntau hom kev tawm tsam sab nraud Cov txheej txheej txheej no ua ib txheej tiv thaiv ntawm cov npoo ntawm cov kauv welded kav, zoo sib cais lawv los ntawm kev xeb ib puag ncig.
Rau qee lub nroog loj tuaj yeem kis tau lub log tsheb, ntxiv rau anti- corrosion coatings, txi} Cov qauv corrosion kuj tseem tau txais. Txawm li cas los xij, thaum cov av tiv taus yog qhov siab dhau lossis kev tiv thaiv pipeline dhau los ntawm dej, kev tiv thaiv kev txi kev tiv thaiv tsis tau. Cov ovi sib txawv - corrosion cov hau kev muaj cov cai sib txawv thiab cov kev xaiv, thiab kev ua haujlwm ib puag ncig ntawm kev tiv thaiv cov tsiaj welded. Los ntawm kev siv tsim nyog anti - kev kho corrosion, lub neej kev pabcuam ntawm cov kauv welded kav hauv kev siv hluav taws xob tuaj yeem txuas ntxiv, txo tus nqi.
Hauv kev xaus, muab kauv welded kav, nrog lawv cov txheej txheem ntau lawm, muaj ntau yam kev ua haujlwm hauv kev ua kom zoo nkauj, thiab siv cov khoom siv tawm hauv nroog thiab ntev.
