Slip-on flanges yog ib txoj hauv kev zoo tshaj plaws rau kev sib txuas cov khoom hauv cov kav dej, txuas cov kav dej, li qub, flanges, thiab lwm yam khoom siv kav dej. Cov txheej txheem kev sib txuas no suav nrog kev vuam, tsim kom muaj kev sib koom ua ke zoo hauv cov kav dej. Slip-on flanges tuaj nyob rau hauv cov khoom thiab cov khoom sib xyaw, nrog lossis tsis muaj caj dab. Cov txheej txheem kev faib tawm yog intricately khi rau kev siv tswv yim, nrog rau cov xwm txheej tshwj xeeb yuav tsum muaj cov qauv sib txawv thiab kev ua haujlwm ntawm flanges.
Cov qauv tsim ntawm cov khoom plam-on flanges yog kev sib piv ncaj nraim. Cov khoom siv tshwj xeeb thaum lub sijhawm tsim khoom tsis yog nruj raws li cov rau pob tw vuam flanges. Cov flanges no feem ntau ua haujlwm hauv kev sib txuas ntawm nruab nrab mus rau cov hlab ntsha qis thiab cov kav dej. Cov txheej txheem ntau lawm rau slip-on flanges yog qhov muaj txiaj ntsig zoo. Hauv ntau qhov xwm txheej uas cov raj xa dej valve ua haujlwm yog tus qauv thiab cov kev xav tau siab tsis siab, plam-on flanges tseem yog qhov kev xaiv zoo.
EEMUA 145 Tshooj 4 qhia txog cov kev cai tshwj xeeb hais txog cov khoom siv tshuaj lom neeg muaj pes tsawg leeg, qhov loj me thiab kev ua siab ntev, cov khoom siv kho tshuab, qhov chaw tiav, thiab lwm yam tsis zoo rau cov khoom plam-on flanges. Raws li cov kev cai ntawm EEMUA 145 Tshooj 4, lub flange nto yuav tsum tau tsim raws li Flat Face (FF), thiab gaskets yuav tsum tau ua hauj lwm raws li tau teev tseg.
Qhov ntev ntawm eEMUA 145 Khoom Slip-On Flange
- Khoom siv:CuNi 90/10 UNS 7060X
- Loj:1/2 nyob rau hauv -4 nyob rau hauv. [16mm-108mm]
- Flange tig:Lub ntsej muag tiaj tus (FF)
- Chaw tsim khoom:Kub forging, Txias forging ua raws li annealing
- Gaskets:CAF 1.5mm tuab
- Bolting:ASTM B150 UNS C63000 txhuas bronze
EEMUA 145 Tshooj 4 hais tias cov khoom siv rau kev tsim cov khoom plam-on flanges yog tooj liab-nickel 90/10, ib qho kev txhim kho ntawm tooj liab-nickel alloy UNS C70600. Kev xaiv cov khoom yog hauv paus hauv kev txiav txim siab xws li corrosion kuj, lub zog, thiab kub endurance. Tus txheej txheem tau lees paub tias cov ntaub ntawv xaiv tau ua raws li cov txheej txheem rau cov tshuaj muaj pes tsawg leeg, cov khoom siv kho tshuab, thiab lwm yam khoom tsim nyog.

EEMUA 145 muaj cov lus qhia dav dav rau qhov ntev ntawm cov khoom plam-ntawm flanges, suav nrog cov ntsiab lus xws li qhov loj, tuab, thiab flange ntsej muag qhov ntev. Cov kev qhia tshwj xeeb no ua lub luag haujlwm tseem ceeb hauv kev lav kev sib raug zoo thiab raug haum hauv cov kav dej. Tus qauv txiav txim siab txog ntau yam ntawm cov yeeb nkab qhov ntau thiab tsawg thiab kev ntsuas siab kom ua tau raws li qhov yuav tsum tau ua ntawm ntau yam kev siv.
