Vim tias cov yeeb nkab muaj ntau ntawm ntau qhov kev lag luam, nws tsis yog qhov xav tsis thoob tias ntau lub koom haum sib txawv cuam tshuam rau kev tsim khoom thiab kev sim cov yeeb nkab rau kev siv thoob plaws ntau yam kev siv.
Raws li koj yuav pom, muaj ob qho tib si sib tshooj nrog rau qee qhov sib txawv ntawm cov txheej txheem cov koom haum uas cov neeg yuav khoom yuav tsum nkag siab kom lawv tuaj yeem ua kom raug specs rau lawv cov projets.
1. ASTM
ASTM International muab cov khoom lag luam thiab cov qauv kev pabcuam thoob plaws ntau yam kev lag luam.Lub koom haum tau tshaj tawm ntau dua 12,000 tus qauv tam sim no siv hauv kev lag luam thoob ntiaj teb.
Ntau tshaj 100 ntawm cov qauv no hais txog cov yeeb nkab steel, tubing, fittings thiab flanges.Tsis zoo li qee lub koom haum cov qauv uas cuam tshuam rau cov yeeb nkab steel hauv kev lag luam tshwj xeeb, ASTM cov qauv npog ntau cov yeeb nkab siv hauv txhua qhov kev lag luam uas koj tuaj yeem xav txog.
Piv txwv li, American Piping Products stocks tag nrho ntawm A106 yeeb nkab.Tus qauv A106 npog seamless carbon steel yeeb nkab rau kev pabcuam kub.Tus qauv ntawd tsis tas yuav txwv cov yeeb nkab rau ib qho kev thov kev lag luam.
2. ASME
American Society of Mechanical Engineers pib tshaj tawm cov qauv kev lag luam thiab cov khoom siv tshuab hauv xyoo 1880 thiab tau ua tus tsav tsheb tom qab kev txhim kho kev nyab xeeb rau cov boilers thiab cov hlab ntsha siab siv thoob plaws hauv kev lag luam.
Raws li cov yeeb nkab feem ntau nrog cov hlab ntsha siab, ASME cov qauv npog ntau yam kev siv yeeb nkab thoob plaws ntau qhov kev lag luam, ib yam li ASTM.Qhov tseeb, ASME thiab ASTM cov qauv yeeb nkab yog qhov zoo ib yam.Txhua lub sijhawm koj pom cov qauv yeeb nkab qhia nrog 'A' thiab 'SA' - piv txwv yog A / SA 333 - nws yog lub cim qhia tias cov khoom ua tau raws li ASTM thiab ASME cov qauv.
3. API
Raws li nws lub npe qhia, American Petroleum Institute yog lub koom haum tshwj xeeb hauv kev lag luam uas, ntawm lwm yam, tsim thiab tshaj tawm cov qauv rau cov yeeb nkab thiab lwm yam khoom siv hauv kev lag luam roj & roj.
Piping ntsuas raws li tus qauv API tuaj yeem zoo sib xws hauv cov khoom siv thiab tsim rau cov kav dej siv hauv kev lag luam hauv lwm cov qauv.API cov qauv nruj dua thiab suav nrog cov kev xeem ntxiv, tab sis muaj qee qhov sib tshooj.
API 5L yeeb nkab, piv txwv li, feem ntau siv hauv cov roj & roj teeb.Tus qauv zoo ib yam li A/SA 106 thiab A/SA 53. Qee qib API 5L yeeb nkab ua raws li A/SA 106 thiab A/SA 53 cov qauv thiab yog li ntawd tuaj yeem siv sib hloov.Tab sis A / SA 106 thiab A / SA 53 yeeb nkab tsis ua raws li txhua yam API 5L.
4. ANSI
Lub koom haum American National Standards Institute tau tsim los tom qab kev sib sau ua ke ntawm ntau lub koom haum kev lag luam hauv xyoo 1916 nrog lub hom phiaj ntawm kev tsim cov qauv kev pom zoo hauv Asmeskas
ANSI tau koom nrog cov koom haum zoo sib xws hauv lwm lub tebchaws los tsim Lub Koom Haum Thoob Ntiaj Teb rau Standardization (ISO).Lub koom haum tshaj tawm cov qauv lees paub los ntawm cov neeg muaj feem cuam tshuam los ntawm thoob plaws ntiaj teb.ANSI tseem ua raws li lub cev lees paub uas pom zoo cov qauv tsim los ntawm cov koom haum ib leeg rau kev saws me nyuam thoob ntiaj teb.
Ntau yam ASTM, ASME thiab lwm yam qauv tau pom zoo los ntawm ANSI raws li cov qauv siv tau.Ib qho piv txwv yog ASME B16 tus qauv rau flanges, li qub, fittings thiab gaskets.Tus qauv tau pib tsim los ntawm ASME, tab sis nws tau pom zoo rau kev siv thoob ntiaj teb los ntawm ANSI.
ANSI txoj kev siv zog tau pab qhib kev lag luam thoob ntiaj teb rau cov neeg tsim khoom thiab cov neeg xa khoom ntawm cov yeeb nkab vim nws lub luag haujlwm hauv kev txhim kho thiab kev siv cov qauv kev lees paub thoob ntiaj teb.
5. Txoj cai kav xa khoom
Nrog ntau xyoo dhau los ntawm kev muab cov yeeb nkab rau cov neeg siv khoom ntawm txhua qhov kev lag luam thoob plaws ntiaj teb, Jindalai Steel Group nkag siab txog qhov nyuaj thiab qhov tseem ceeb ntawm ntau tus qauv uas tswj hwm kev tsim khoom thiab kev sim cov yeeb nkab.Cia peb siv qhov kev paub no rau qhov zoo ntawm koj txoj haujlwm.Los ntawm xaiv Jindalai ua koj tus neeg muag khoom, koj tuaj yeem tsom mus rau qhov tseem ceeb tshaj plaws rau koj es tsis txhob poob rau hauv cov ntsiab lus.Jindalai cov yeeb nkab steel tuaj yeem ua tau raws li tag nrho cov qauv uas tau hais los saum toj no.
Yog tias koj muaj kev xav tau kev yuav khoom, thov qhov kev tsocai.Peb yuav muab ib qho uas tau txais koj raws nraim cov khoom koj xav tau sai.Xa koj cov lus nug thiab peb yuav zoo siab los sab laj koj tus kws tshaj lij.
