Qhov tseem ceeb ntawm ob chav welded kav dej thiab polyurethane kab tsuag hauv cov yeeb nkab vuam
Ob Chav Welded Yeeb NkabHais txog cov yeeb nkab uas tau muab ob npaug welded los tsim lub zog, ntau ruaj sib koom ua ke. Hom yeeb nkab feem ntau siv hauv kev siv hluav taws xob uas vuam zoo thiab lub zog yog qhov tseem ceeb. Cov txheej txheem vuam sib cais yuav siv vuam cov tswv yim kom folding ob qho kav dej ua ke kom ntseeg tau tias muaj zog thiab sib txuas tau sib txuas. Tsis tsuas yog ua qhov no txhim kho lub zog tag nrho thiab ruaj khov ntawm cov yeeb nkab, nws kuj yuav txo qhov kev pheej hmoo ntawm vuam tsis xws luag thiab muaj peev xwm.
Polyurethane Lamed Yeeb Nkab, ntawm qhov tod tes, yog cov yeeb nkab hlua nrog cov polyurethane txheej uas muab kev tiv thaiv ntxiv rau kev tiv thaiv kev puas tsuaj, kev puas tsuaj, thiab tshuaj lom neeg. Cov kab ntawv tau thov rau sab hauv ntawm cov yeeb nkab kom tsim kev thaiv ntawm cov kua dej tau thauj khoom thiab cov hlau npoo ntawm cov yeeb nkab. Polyurethane cov kav dej tau raug txais txiaj ntsig tshwj xeeb rau cov kav dej uas siv los ua cov tshuaj corrosive lossis kev ua haujlwm nyob rau hauv Harsh ib puag ncig. Polyurethane ntaub qhwv tsis tsuas yog txuas lub neej ntawm koj kav dej, lawv kuj txo qis kev pheej hmoo ntawm cov dej xau thiab kev txij nkawm.

Tsis tas li ntawd, kev tsim cov khoom ua haujlwm ntawmMuab Kauv Hlau Kavyog qhov siab dua li ntawm seamless steel kav. Rau seamless yeeb nkab, cov txheej txheem ntau lawm yuav ua rau cov khoom siv hlau billet los ntawm perforated pas nrig, ua rau muaj qeeb qeeb thiab ntau cov txheej txheem nyuaj. Hauv kev sib piv, muab kauv welded yeeb nkab tuaj yeem tsim tawm hauv cov kab uas sib dos loj thiab ntev, ua rau muaj cov sijhawm luv luv thiab muaj txiaj ntsig. Qhov no ua kom muaj cov kav dej tsis tu ncua hauv cov kav dej siab hauv cov sijhawm luv, ua rau nws muaj kev txhim kho thiab txuag sijhawm sijhawm rau kev lag luam ntau yam.
Lwm qhov tsis muaj txiaj ntsig ntawm cov kauv welded kav yog lawv cov kev tiv thaiv sab nraud sab nraud thiab kev ntxhov siab. Welds muab cov kav ntev ntxiv, tso cai rau cov kav dej kom tiv thaiv siab dua qhov kev ntsuas siab dua li seamless kav. Cov cuab yeej no yog qhov tshwj xeeb rau kev siv hauv cov roj thiab roj kev lag luam, qhov twg cov raj xa dej, qhov twg yog qhov tseem ceeb hauv sab hauv thiab sab nraud. Los ntawm kev siv cov kauv welded kav dej, cov tuam txhab tuaj yeem xyuas kom muaj kev nyab xeeb thiab txuag kev thauj khoom ntawm cov peev txheej tseem ceeb no.
Nyob rau hauv cov yeeb nkab vuam, kev sib xyaw ua ke ntawm ob peb welded yeeb nkab thiab polyurethane kab kab tsuag muaj ntau yam zoo. Thawj thiab foremost, kev siv ntawm ob-welded yeeb nkab ua kom cov yeeb ncaj ncees ntawm cov yeeb nkab, txo qhov tau ua kom muaj qhov tsis xws luag thiab qhov tsis ua tiav. Qhov no yog tshwj xeeb yog qhov tseem ceeb hauv kev lag luam ib puag ncig uas cov kav dej yog qhov siab siab thiab kub hloov kho. Tsis tas li ntawd, kev siv cov roj av polyurethanes muab ib txheej txheej ntxiv ntawm kev tiv thaiv corrosion thiab hnav, txuas ntxiv mus rau cov yeeb nkab lub zog thiab kav ntev.
Tsis tas li ntawd, kev siv cov yeeb nkab ob-welded thiab polyurethane-lined cov yeeb nkab tuaj yeem muab cov neeg xa khoom siv nyiaj txiag. Lub zog txhim kho lub zog thiab cov yeeb nkab siv welded tuaj yeem txo qhov xav tau ntawm kev kho kom nquag thiab kev txuag sijhawm thiab nyiaj hauv lub sijhawm ntev. Ib yam li ntawd, cov txheej tiv thaiv tau muab los ntawm Polyurethane-liped cov yeeb nkab tuaj yeem txuas qhov kev pabcuam lub neej ntawm cov yeeb nkab, yog li txo cov nqi kho thiab kho cov nqi.
Hauv kev xaus, kev siv ntawm ob chav welded pipes thiab polyurethane cov kav dej tab yog qhov tseem ceeb hauv cov yeeb nkab vuam. Cov khoom siv no tsis tsuas yog ua kom cov qauv kev ncaj ncees thiab lub zog ntawm cov raj xa dej, tab sis kuj tseem muab kev tiv thaiv tsim nyog tiv thaiv corrosion, puas muaj tshuaj tua rog thiab tshuaj lom neeg. Los ntawm kev sib xyaw ua ke cov thev naus laus zis ua rau kev tsim kho pipeline, tuaj yeem ua tiav ntau theem kev ntseeg tau, kev ua tau zoo thiab raug nqi ua haujlwm rau lawv cov raj xa hluav taws xob.
