HT PIPE muab txhua yam sib txawv thiab ntsuas ntawm flanges. Thov koj txhob xav li castiv tauj pebrau cov lus qhia ntxiv txog cov khoom thiab tus nqi.
ASME B16.47 Series B Chav Kawm 400 Weld Neck Flanges, CovASME B16.47txheem tswj loj - txoj kab uas hla steel yeeb nkab flanges. Thaum soj ntsuam nrog qhov ntau thiab tsawg dua 24 ntiv tes, cov kws ua haujlwm yuav tsum xaiv ib qhoSeries Alos yogSeries Bkev teeb tsa.
Thaum ob qho tib si poob rau hauv tib tus qauv overarching, lawv qia los ntawm cov keeb kwm sib txawv thiab tsis sib xws geometrically.
- Series A (Muaj los ntawm MSS SP-44):Nyias yuav tuab dua, hnyav dua, thiab siv tsawg dua, loj dua - txoj kab uas hla bolts. Nws yog tsim los tswj cov khoom siv sab nraud thiab feem ntau siv rau hauv daim ntawv thov rugged pipeline.
- Series B (Drived los ntawm API 605):Tsom rau ntawm qhov kev tsim qauv ntau dua. Nws siv ntau dua ntawm cov bolts me me. Qhov kev tsim no txo qhov hnyav ntawm flange tag nrho, txo qis qhov profile clearance, thiab feem ntau nthuav qhia kev siv nyiaj txiag ntau dua rau cov txheej txheem piping daim ntawv thov nyob rau hauv cov hnab ntawv compact.
Vim li cas thiaj Qhia Ib Chav Kawm 400 Kev Ntsuas?
A Chav Kawm 400kev xaiv sawv cev rau lub siab- qhov ntsuas kub ntawm lub flange. Nws haum qhov sib npaug ntawm Chav Kawm 300 tus qauv kev lag luam thiab qhov hnyav dua Chav Kawm 600.
Kev xaiv chav kawm 400 siab ntsuas tiv thaiv dhau - engineering- uas tuaj yeem ua rau cov khoom siv thiab cov nqi thauj khoom rau cov kav xa dej loj -thaum muab cov kev nyab xeeb tsim nyog tshaj li cov chav kawm 300 PSI.
Kev xaiv cov khoom siv thiab metallurgy
Qhov kev ua tau zoo ntawm ASME B16.47 flange yog nyob ntawm nws cov metallurgy. Vim hais tias cov loj - txoj kab uas hla flanges undergo tseem ceeb forge - nias thiab siab - yield vuam ua hauj lwm, cov khoom chemistry tseem ceeb.
Carbon hlau (ASTM A105 / A350 LF2)
Siv nyob rau hauv cov txheej txheem kev lag luam txheej txheem loops thiab midstream daim ntaub ntawv.ASTM A105 1yog tus qauv hauv paus rau kev pabcuam ambient thiab kub dua. Rau qhov txias- huab cua ib puag ncig- xws li cov roj xuab zeb ntawm Northern Canada lossis siab - qhov chaw siab tshaj -ASTM A350 LF2yog teev los xyuas kom meej Charpy V-qhov cuam tshuam toughness mus rau -50℉ (-45℃).
Siab -Yield Carbon Steel (ASTM A694 F52 txog F70)
Rau kev hla -cov kav xa hluav taws xob hauv lub tebchaws sib piv siab - lub zog API 5L kab kav dej (xws li X60, X65, X70), siab- tawm los forging qib xws liASTM A694 Cov khoom lag luamtsim nyog. Lawv tso cai rau cov kws tshaj lij ua kom cov phab ntsa nyias nyias ntawm qhov siab - tensile yeeb nkab yam tsis muaj kev cuam tshuam cov ciam teb siab ntawm qhov sib koom ua ke.
Stainless thiab Alloy Steels (ASTM A182 F316L / Duplex)
Nyob rau hauv ib puag ncig corrosive los yog marine ib puag ncig, xws li downstream petrochemical refining los yog ntug dej hiav txwv desalination infrastructure,ASTM A182 F316L Cov Lus Qhialos yog duplex stainless hlau (F51 / F53) tiv thaiv qhov tseem ceeb gasket zaum qhov chaw los ntawm pitting thiab crevice corrosion.
