Lub kauv steel yeeb nkab thiab steel yob raj yog welded steel kav, uas txawv heev nyob rau hauv cov txheej txheem ntau lawm.
Lub kauv steel yeeb nkab yog ib qho kauv seam steel yeeb nkab raws li cov hlau yob phaj raws li cov khoom siv raw, uas feem ntau yog nyem thiab tsim, thiab welded nrog cov txheej txheem tsis siv neeg ob-sided arc vuam txheej txheem.Qhov ntev ntawm cov kauv steel yeeb nkab yog 12 meters. , thiab kev xa khoom ntawm tus kav yog txiav txim siab, thiab cov lus qhia tshwj xeeb yog qhov siab tshaj 219mm.
Cov hlau phaj yob lub raj siv cov txheej txheem tannant vuam, uas tuaj yeem tsim cov kav hlau steel nrog txoj kab uas hla ntawm ntau tshaj 400 thiab 8-100 hli phab ntsa thickness. Feem ntau tsis txhob teeb tsa tus kav, thiab kev xa khoom feem ntau yog siv.
Cov qauv kev ua haujlwm rau steel phaj yob cov khoom lag luam yog: GBT50205-2001, GBT3092-2001, thiab lwm yam.Roll kav dej yog siv dav hauv cov haujlwm xws li roj av, tshuaj lom neeg kev lag luam, kev thauj mus los hauv ntuj, pawg thiab dej hauv nroog. , cua sov, roj thiab lwm yam haujlwm.
Tus nqi ntawm tib tus qauv ntawm cov hlau phaj yob lub raj yog siab dua li cov kauv steel yeeb nkab. Lub steel phaj yob raj yog tsuas yog siv nyob rau hauv tsis yog-qauv, los yog nyob rau hauv kev lag luam nrog tuab tuab.
Lub kauv steel yeeb nkab tsis muaj qhov txwv ntawm lub neej, thiab kev pabcuam lub neej yog feem ntau cuam tshuam nrog kev ua haujlwm ib puag ncig thiab cov txheej txheem tsim khoom.In thiaj li yuav txuas ntxiv lub neej kev pabcuam ntawm cov kav hlau kav, qhov kev ua haujlwm tsis zoo ntawm cov yeeb nkab steel yog anticorrosive.
Anticorrosive kauv steel yeeb nkab yog hais txog kev ua cov tshuaj lom neeg lossis cov tshuaj electrochemical thaum lub sijhawm ua cov txheej txheem anticorrosive, uas tuaj yeem tiv thaiv kom tsis txhob muaj cov tshuaj lom neeg lossis cov tshuaj electrochemical thaum lub sijhawm thauj mus los thiab siv.Anticorrosive spiral steel kav tuaj yeem tiv thaiv tau zoo lossis qeeb lub neej ntawm cov yeeb nkab steel thiab txo tus nqi ntawm cov yeeb nkab steel.
Muaj ntau cov kav dej hauv tsev los tiv thaiv corrosion los tiv thaiv cov khaubncaws sab nraud povtseg xws li roj av asphalt, PE tsho thiab PE ua npuas ncauj tsho, epoxy thee porcelain xim, epoxy hmoov thiab peb-txheej cov qauv, epoxy thee pettelona band (PF hom), Corruption epoxy thee pommellar cooler band (RPC hom), thiab lwm yam., feem ntau cov kav raj xa dej los tiv thaiv corrosion yog peb txheej ntawm PE cov qauv sib xyaw, ib txheej txheej hmoov epoxy, PF hom txias entanglement band, RPC txias-type coldTogether.
1. Petroleum asphalt, cov khoom siv dav dav, tus nqi qis.Txawm li cas los xij, kev ua haujlwm tsis zoo, qhov tsis zoo yog qhov nyuaj rau lav, thiab ib puag ncig muaj kuab paug hnyav.
2. Oreoxanum asphalt, yooj yim rau kev khiav lag luam, tab sis lub sij hawm npog yog ntev, thiab nws cuam tshuam los ntawm ib puag ncig. Nws tsis haum rau kev ua haujlwm hauv cheeb tsam. Nws yog ib qho nyuaj rau tsim hauv qab 10 degree C.
3. Epoxy hmoov anti-corrosion, siv electrostatic spray txheej, melted nrog lub cev nrog tib yam khoom, thiab muaj zog adhesion, tab sis cov waterproof kuj ntawm epoxy hmoov yog tsis zoo (siab dej nqus tus nqi yog 0. 83%).Kev tsim kev tiv thaiv coj tau qee qhov teeb meem.Cov khoom siv ntawm qhov chaw siab, kev ua haujlwm nyuaj, thiab qhov zoo tsis yooj yim rau kev tswj.
4. 3PE thermal retractable cov ntaub ntawv, muaj zog sealing ntawm lub raj xa dej, siab mechanical zog, muaj zog waterproofing, ruaj khov zoo, yooj yim siv, zoo applicability, thiab tsis polluting ib puag ncig.PE tus nqi nqus dej yog tsawg (tsawg dua 0). 01%), tib lub sijhawm, siab epoxy zog, tsis tshua muaj dej nqus, thiab cov kua nplaum kub melting zoo, thiab lwm yam, muaj kev ntseeg siab tiv thaiv corrosion. Qhov tsis zoo yog qhov piv nrog lwm cov khoom siv ntxiv, raug nqi.
5. Kev tsim kho ntawm PF hom thiab RPC -type txias band yog yooj yim thiab yooj yim rau kev khiav lag luam. Peb hom kev teeb tsa cov kua nplaum rau kev txhawb nqa PF hom epoxy thee pilum tuaj yeem tsim nyob rau hauv ib puag ncig, txhua lub caij, thiab txhua qhov kub thiab txias.
6. Cov yam ntxwv ntawm txoj siv txias entanglement thiab 3PE tshav kub txoj siv yog: haum rau lub ntsiab anticorrosive txheej pipeline ntawm ntau yam ntaub ntawv, thiab lwm yam yog haum rau lub ntsiab lub cev anticorrosive txheej pipelines nrog tib los yog ze rau cov khoom.
Raws li qee cov kav dej tau tsim, qee cov kav dej kuj yuav tsum tau ua kom sov rau tib lub sijhawm. Petroleum yog ib qho kev sib tov sib xyaw ua ke, uas yooj yim rau corrodes pipelines. Anti-corrosion yog tsim nyog.Skating thiab contraction tuaj yeem khov cov kav dej, cuam tshuam cov khoom ruaj khov.
