Q1: Kab yeeb kab yog dab tsi?
A1:Kab yeeb yog ib hom yeeb nkab siv rau kev thauj cov kua xws li roj, roj av, thiab dej dhau mus ntev. Nws yog tsim los kom withstst lub siab siab thiab hnyav ib puag ncig. Cov kav pipes no feem ntau siv nyob rau hauv cov kav dej rau kev thauj mus los. Lawv tuaj hauv ntau qhov ntau thiab tsawg, qib kawm, thiab tshwj xeeb yog nyob ntawm daim ntawv thov. Kab xaub kav yuav tsum ua kom tiav cov qauv kev lag luam nruj ua kom muaj kev nyab xeeb thiab kav ntev.
Q2: Cov ntaub ntawv dab tsi yog kab kav ua los ntawm?
A2:Cov kab kav yog feem ntau ua los ntawm cov roj carbon steel lossis cov hlau roj qis vim lawv lub zog thiab lub zog. Cov hlau High-qib zoo li API 5L X70 lossis X70 lossis X80 yog feem ntau siv rau cov ntawv thov siab. Qee tus kav dej kuj tseem tuaj yeem muaj cov txheej corrosion-resistant txheej los yog linings. Stainless hlau lossis chav hlau duplex yog siv rau cov chaw muaj teeb meem loj. Kev xaiv cov khoom yog nyob ntawm yam zoo li siab, ntsuas kub thiab kua dej.
Q3: Cov Qauv Tseem Ceeb Rau Cov Kab Kav Pipes?
A3:Cov txheej txheem pom dav dav tshaj plaws rau cov kab kav yog API 5L, teeb los ntawm Asmeskas Petroleum Institute. Lwm cov qauv suav nrog ISO 3183, ASTM A106, thiab ASME B36.10M. Cov qauv qauv txhais tau qhov ntev, cov neeg kho tshuab, thiab kev kuaj mob. Ua raws cai kom muaj kev nyab xeeb thiab kev sib raug zoo hauv cov raj xa hluav taws xob. Thaj chaw sib txawv kuj tseem muaj cov kev cai ntxiv.
Q4: Npaum li cas cov kab raj xa khoom?
A4:Kab kav kav yog tsim los ntawm cov txheej txheem zoo li seamless (Mandrel Zeb) lossis weld (ERW, pom, lsaw). Seamless kav yog tsim los ntawm tho cov khoom siv hlau billet, thaum welded kav yog tsim los ntawm cov hlau stem lossis coils. Cov txuj ci siab zoo li jcoe (j-ing, c-ing, o ing, kev nthuav dav) yog siv rau cov kav dej loj. Kev tswjhwm zoo xws li ultrasonic kuaj, hydrostatic kev sim, thiab pom kev kuaj xyuas. Kev tsim qauv ua kom zoo nkauj ua kom muaj zog thiab xau pov thawj kev ua haujlwm.
Q5: Cov kev siv ntawm cov kab kav dej yog dab tsi?
A5:Kab xaub kav yog siv hauv cov roj thiab roj sib kis pipelines, ob qho tib si onshore thiab sab nrauv. Lawv kuj tau siv nyob rau hauv cov dej khoom siv cov dej tshuab, cov nroj tsuag tsiaj, thiab koog tsev kawm ntawv cua sov network. Qee cov kav dej tshwj xeeb yog siv rau kev thauj mus los yog cov phiaj xwm carbon. Lawv lub durability ua rau lawv haum rau cov mob hnyav xws li Arctic pipelines lossis tob-nruab.
