1. ** Dab tsi yog A105 siv rau? **
ASTM A105 yog qhov tshwj xeeb rau cov ntaub ntawv zam txim rau cov steel hlau xav siv rau kev siv hauv cov kev pabcuam siab ntawm cov kev pabcuam hauv ambient thiab siab dua-kub. Nws yog feem ntau siv los ua flanges, fittings, li qub, thiab lwm qhov siab-muaj feem rau cov tshuab luam ntawv. Nws yog * tsis yog * ib qho yeeb nkab sib cais nws tus kheej.
2. ** Dab tsi yog qhov sib txawv ntawm ASTM thiab ASME YEEB? **
* ** ASTM (American Society rau kev sim thiab cov ntaub ntawv): ** Muaj cov txheej txheem kev ntsuas thiab cov tshuaj ntsuam xyuas rau cov yeeb nkab steel, astm A53 rau Welded yeeb nkab). ASTM piav txog cov tshuaj lom neeg cov tshuaj muaj pes tsawg leeg, cov khoom siv neeg siv neeg, qhov ntev, thiab kev kuaj mob rau cov yeeb nkab khoom nws tus kheej.
* ** ASME (Asmeskas Society of Neeg Kho Tshuab ASME muab txoj cai rau tus qauv *, * Kev Tshuaj Xyuas *, thiab * Kev Ntsuam Xyuas * Siv Pipe * Siv Pipes Rooj Sib Tham ASTM (lossis lwm yam) cov lus qhia. ASME tsis tsim nws cov khoom siv cov khoom; Nws siv thiab nyiaj muas lawv.
3. ** Dab tsi yog qhov sib txawv ntawm API thiab ASME? **
* ** API (Lub Koom Haum Asmeskas Cov Qauv Tsim): ** Tus qauv tsim hluav taws xob muaj roj ntsha rau cov roj thiab roj kev lag luam. Cov yeeb nkab tseem ceeb muaj xws li API 5L (rau kab yeeb nkab) thiab API 5CT (rau casing thiab tubing). APK Cov Qauv Kawm txog qhov tshwj xeeb rau kev tshawb nrhiav, kev tsim khoom, kev thauj mus los, thiab ua kom muaj txiaj ntsig ntawm hydrocarbons. Lawv npog cov khoom siv, qhov ntev, kev sim, thiab feem ntau cov ntawv thov yuav tsum muaj.
* ** ASME: ** Tsom ntsoov rau cov khoom siv dav dav thoob plaws ntau kev lag luam (Fais fab tshuaj tua hluav taws xob, kev tsim tshuaj, kev tsim tshuaj,. Nws boiler thiab siab hlab ntsha code (BPVC) thiab B31 Piping Codes tswj hwm kev nyab xeeb tsim qauv, kev ua haujlwm, cov hlab ntsha, thiab cov raj raj piping. ASME Cov Qauv Qhia Txog Cov Cai Siv Egineering
4. ** Cov yeeb nkab qib yog dab tsi? **
ASME nws tus kheej tsis txhais tau cov yeeb nkab tshwj xeeb "qib". Hloov chaw, ASME boiler thiab siab lub nkoj siab code (BPC) thiab Exme B31 Piping Codes tau tsim los ntawm lwm cov koomhaum tsim tau los ntawm lwm cov khoom siv Thaum cov xaim xaim cov ntaub ntawv tshwj xeeb (zoo li ATTM A106) yog saws los ntawm ASME, nws tau txais "SA" LOJ (piv txwv li, SA106). Cov "qib" (piv txwv li, qib b) yog txhais nyob rau hauv thawj ASTM lossis API specification.
5. ** Dab tsi yog qhov sib txawv ntawm API thiab ASTM? **
* ** API (American roj av lub koom haum): ** Tsim cov qauv * tshwj xeeb * txiav rau cov roj thiab roj kev lag luam. Nws cov qauv yeeb nkab (zoo li API 5L rau kab yeeb, API 5CT rau kev ua haujlwm, xws li kev kuaj mob hydrocarbon feem ntau muaj feem xyuam rau lub raj xa dej uas muaj feem xyuam rau lub raj dej lossis cov chaw ze.
* ** ASTM (American Society rau kev sim thiab cov ntaub ntawv): ** nthuav dav ntau cov qauv ntawm cov qauv * Cov ntaub ntawv tshwj xeeb thiab cov qauv xeem * siv ntau txoj kev lag luam. ATM cov yeeb nkab specs (zoo li ATTM A106, A53, A333) Cov khoom siv tshuab, thiab ntsuas cov hlau, alloy, stainless, thiab lwm yam). Lawv muaj ntau lub hom phiaj-hom phiaj tab sis tau txais los ntawm lwm cov cim (zoo li ASME) rau kev siv hauv siab nruab.
