** 1. API sawv ntsug rau? **
API sawv rau Miskas lub koom haum roj av.
** 2. Dab tsi yog API GL4 thiab GL5? **
API GL4 thiab GL5 yog kev pabcuam cov kev tsim qauv rau cov iav lubricants. GL4 txhais tau cov roj rau lub zog, tshwj xeeb tshaj yog cov txiaj ntsig hypoid, ua haujlwm nyob rau hauv nruab nrab mus rau cov xwm txheej hnyav. GL5 nyob rau cov roj rau lub zog, tshwj xeeb tshaj yog hypoid kom nyob rau hauv high} ceev {{{} Poob siab thauj khoom. Lawv tsis tau sib pauv tau, raws li GL5 roj muaj ntau dua theem siab (EP) cov tshuaj ntxiv uas tuaj yeem yog cov ntaub ntawv siv hauv qee cov ntawv thov GL4.
** 3. Dab tsi yog qhov sib txawv ntawm API 5L thiab A106? **
API 5L yog qhov tshwj xeeb rau kab yeeb siv kab hlau siv feem hauv kev thauj mus los hauv raj dej txuas ntxiv rau cov roj thiab roj. A106 yog ib qho kev qhia tshwj xeeb rau seamless cov hlau yeeb nkab npaj rau siab- kub kev pab, xws li nyob rau hauv cov hwj huam kev siv hluav taws xob, ua kom cov nroj tsuag. Cov qhov sib txawv tseem ceeb yog lawv cov ntawv thov npaj: API 5L yog rau kev sib kis tau tus mob pipelines, thaum A106 yog rau cov piping siab thiab siab} kev pabcuam kub.
** 4. Dab tsi yog qhov tsawg kawg yog los lub zog ntawm API 5L? **
Qhov tsawg kawg ntawm lub zog zog ntawm API 5L sib txawv ntawm qib thiab cov ntawv foos (seamless lossis welded). Piv txwv li, cov qib qib B muaj qhov tsawg kawg nkaus lub zog ntawm 245 MPa (35,000 PSI). Cov qhab nia siab dua li X70 muaj tsawg kawg nkaus zog zog ntawm 483 MPa (70,000 PSI).
** 5. Dab tsi yog qhov ntsuas kub rau API 5L Qib B? **
API 5L Qib B yog tsim tshwj xeeb rau kev pabcuam kub kub. Thaum nws tuaj yeem siv nyob rau hauv ntau ntawm cov kub, nws cov khoom siv neeg muaj ntawv pov thawj ntawm chav sov. Rau tsawg - kub kev pab, cuam tshuam kev ntsuas yog qhov yuav tsum tau ua kom nruj, thiab rau kev nce qib F lossis 204 Qib B yog ib txwm muaj ntau dua.
