ASME B16.20 Stainless hlau RF kauv lub qhov txhab gasket saj zawg zog graphite muab tub lim Nws yog cov hlau sealing gasket dav siv hauv flange kev sib txuas ntawm siab - kub thiab siab - cov kav dej siab, uas ua raws li cov lus qhia ntawm American Society of Mechanical Engineers (ASME) standard B16.20.
ASME B16.20 Stainless hlau RF kauv qhov txhab gasket saj zawg zog graphite muab tub ntxhais Nta:
1: Txuj hauv paus: Ua raws li ASME B16.20 "Hlau Gaskets rau Hlau Yeeb Nkab Flanges".
2: Hom qauv: Kauv Qhov txhab, tsim los ntawm V- zoo li cov hlau tsis muaj steel hlau strips thiab hloov tau yooj yim graphite fillers hloov qhov txhab.
3: Nruab nrog lub nplhaib sab nraud (RF): Tsim nyog rau tsa lub ntsej muag flanges (RF), lub nplhaib sab nrauv ua haujlwm raws li qhov chaw, tiv thaiv tshuab, thiab txwv kev txwv.
4: Cov khoom siv muab tub lim: Slexible Graphite, uas muaj qhov kub thiab txias tsis kam, tshuaj lom neeg ruaj khov, thiab ua haujlwm zoo.
5: Cov xwm txheej siv tau: Kub thiab kub siab, corrosive lossis tshuaj lom nruab nrab ua haujlwm hauv kev lag luam xws li roj av, tshuaj, thiab lub zog.
Cov khoom sib xyaw ua ke (kev teeb tsa ntau)
Hoop Khoom:
304 / 304L
316 / 316L
321/347 (tsim rau qhov kub thiab txias los yog ruaj khov xav tau)
Cov khoom siv nplhaib sab nraud: feem ntau yog carbon steel (CS) lossis stainless hlau (xws li 304/316), xaiv raws li kev ua haujlwm.
Ntim: Saj zawg zog graphite, nrog rau qhov kub siab tshaj plaws ntawm 450℃C (pom zoo tsawg dua lossis sib npaug li 600℃C hauv oxidizing media)
kev ua haujlwm tsis zoo
Kev ntsuas siab: Txhawb 150 # txog 2500 # (Class).
Qhov kub thiab txias: -196 ° C txog 700 ° C (tsis muaj oxidizing ib puag ncig); Nws raug nquahu kom tuav qhov kub tsawg dua lossis sib npaug li 600 ° C hauv qhov chaw oxidizing.
Yam tsawg kawg nkaus preload siab: Y=68 MPa.
Sealing coefficient: m=2.5-4
Dimensions thiab specifications
Nominal txoj kab uas hla (NPS): los ntawm 1/2 "mus rau 64".
Thickness: feem ntau 4.5 hli (sealing element).
Lub nplhaib sab hauv (raws li ASME B16.20):
900 # thiab siab dua: Thaum NPS Ntau dua lossis sib npaug rau 24, yuav tsum muaj lub voj sab hauv;
1500 #: Thaum NPS Ntau dua lossis sib npaug rau 12, yuav tsum muaj lub voj sab hauv;
2500 #: Thaum NPS Ntau dua lossis sib npaug rau 4, yuav tsum muaj lub voj sab hauv;
PTFE filling gasket: yuav tsum muaj lub nplhaib puab;
Flexible graphite filling: Nws raug nquahu kom muaj lub nplhaib sab hauv, tshwj xeeb tshaj yog nyob rau hauv siab bolt loads lossis corrosive media
