RTJ flange ndi mtundu wa flange womwe umagwiritsidwa ntchito polumikizira mapaipi.RTJ ndiye chidule cha Ring Type Joint, kutanthauza kuti mphete yosindikiza gasket.
Ma RTJ flanges nthawi zambiri amapangidwa ndi chitsulo chokhala ndi ma groove apadera ozungulira ndi ma bevel pamtunda wa flange.Kapangidwe kameneka kamatha kusungabe kusindikiza kwabwino kwa flange pansi pa kutentha kwambiri komanso kupanikizika.
Ma RTJ flanges amagwiritsidwa ntchito kwambiri m'minda monga petrochemical, kayendedwe ka gasi, ndi kupanga zombo, ndipo amafunika kupirira zovuta monga kuthamanga kwambiri, kutentha kwambiri, ndi dzimbiri lamphamvu.Nthawi zambiri amalumikizidwa ndi zida monga mapaipi, ma valve, ndi mapampu, ndipo amagwira ntchito yofunika kwambiri pama projekiti osiyanasiyana a uinjiniya.
Mitundu yodziwika bwino ya flange imaphatikizapokuwotcherera khosi flange, flange yofunika,khungu lakhungu,ndiAmerican standard khosi welded flange
Miyezo wamba yapadziko lonse lapansi ndi
ANSI B16.5
ASME B16.47 Series A
ASME B16.47 Mndandanda wa B
Chithunzi cha BS3293
Muyezo wa RTJ flange umapangidwa kutengera mfundo izi:
1. API pipeline down joint (muyezo wa RTJ2: R-2, R-3, R4, R5, ndi R-6)
2. International muyezo centimita mndandanda: M-1, M-2, M-3, M-4, M-5, ndi M-6
Komabe, ziyenera kudziwidwa kuti pangakhale kusiyana pakati pawoZithunzi za RTJza miyezo yosiyana, ndi zitsanzo zoyenera ndi ndondomeko ziyenera kusankhidwa malinga ndi zosowa zenizeni pozigwiritsa ntchito.
Makhalidwe a RTJ flange miyezo ndi chofunikira pa makulidwe, omwe amagawidwa m'mitundu wamba komanso yamphamvu kwambiri.Kufunika kwa makulidwe amtundu wokhazikika ndi 100mm, pomwe makulidwe amtundu wamphamvu kwambiri ndi apamwamba, omwe amatha kufika 120mm kapena kupitilira apo.
Pali zofunika zina zapadera mu RTJ flange muyezo, mwachitsanzo, mitundu ina ya olowa angafunike malo olimbikitsira kumapeto kwa olowa pa notch pa unsembe kupewa kutsetsereka.Mitundu ina yapadera yamalumikizidwe, monga maulumikizidwe apamwamba kwambiri, angafunikenso kuyika mbali ya masika kuti awonjezere mphamvu ya axial.
Muyezo wa RTJ flange umapangitsa kuti zitheke kulumikiza mapaipi ndi zida zina zothamanga kwambiri, kupangitsa kuti dongosolo lonse likhale lotetezeka, lodalirika, komanso lolimba.Ili ndi mitundu ingapo yamapulogalamu ndipo imatha kukwaniritsa zofunikira zamitundu yosiyanasiyana m'magawo osiyanasiyana.Pakawonedwe kantchito, chimodzi mwazabwino za muyezo uwu ndikuti umachepetsa nthawi yolumikizira mapaipi pamakina pakuyika ndi kukonza, ndipo utha kukulitsa kwambiri kutalika kwa mapaipi ndikuwonetsetsa kulumikizidwa kotetezeka, ndikupangitsa kuti ntchito ikhale yotetezeka.
