ʻO ka flange RTJ kahi ʻano o ka flange i hoʻohana ʻia i nā pilina pipeline.ʻO RTJ ka pōkole no Ring Type Joint, ʻo ia hoʻi ke apo sealing gasket.
Hana ʻia nā flanges RTJ i ka metala me nā ʻāpana pōʻai kūikawā a me nā bevel ma ka ʻili flange.Hiki i kēia hale ke mālama i ka hana hoʻopaʻa maikaʻi ʻana o ka flange ma lalo o ke kūlana kiʻekiʻe a me ke kaomi.
Hoʻohana mau ʻia nā flanges RTJ i nā kula e like me ka petrochemical, ka lawe ʻana i ke kinoea kūlohelohe, a me ka hana moku, a pono e kū i nā kūlana paʻakikī e like me ke kiʻekiʻe kiʻekiʻe, ke kiʻekiʻe wela, a me ka corrosion ikaika.Hoʻopili pinepine ʻia lākou i nā mea hana e like me nā pipelines, valves, a me nā pumps, a he hana koʻikoʻi i nā papahana ʻenekinia like ʻole.
Aia nā ʻano flange maʻamauwelding neck flange, puʻu huikau,flange makapō, aʻAi maʻamau ʻAmelika welded flange
ʻO nā kūlana honua maʻamau
ANSI B16.5
ASME B16.47 Mokuna A
ASME B16.47 Māhele B
BS 3293
Hoʻokumu ʻia ka maʻamau RTJ flange ma muli o nā kūlana aʻe:
1. Paipu API ma lalo o ka hui (RTJ2 maʻamau: R-2, R-3, R4, R5, a me R-6)
2. Nā moʻo kenimika maʻamau maʻamau: M-1, M-2, M-3, M-4, M-5, a me M-6
Eia naʻe, pono e hoʻomaopopo ʻia he ʻokoʻa paha ma waenaRTJ flangeso nā kūlana like ʻole, a pono e koho ʻia nā hiʻohiʻona kūpono a me nā kikoʻī e like me nā pono maoli i ka wā e hoʻohana ai iā lākou.
ʻO ke ʻano o nā kūlana flange RTJ ka koi no ka mānoanoa, i hoʻokaʻawale ʻia i nā ʻano maʻamau a me nā ʻano ikaika kiʻekiʻe.ʻO ka mānoanoa koi no ka ʻano maʻamau ʻo 100mm, ʻoiai ʻoi aku ka mānoanoa no ke ʻano ikaika kiʻekiʻe, hiki ke piʻi i ka 120mm a i ʻole.
Aia kekahi mau koi kūikawā i ka maʻamau RTJ flange, no ka laʻana, pono paha i kekahi mau ʻano o nā hui ke koi i kahi wahi hoʻoikaika ma ka hope o ka hui ma ka notch i ka wā o ka hoʻokomo ʻana e pale aku i ka paheʻe.ʻO kekahi mauʻano kūikawā o nā hui, e like me ke kiʻekiʻe loa o nā hui, pono paha e hoʻokomo i kahiʻaoʻao puna e hoʻonui i ka ikaika axial.
Hiki i ka RTJ flange standard ke hoʻohui i nā pipeline a me nā mea hana kiʻekiʻe kiʻekiʻe, e hana i ka ʻōnaehana holoʻokoʻa i palekana, ʻoi aku ka hilinaʻi, a ʻoi aku ka lōʻihi.Loaʻa iā ia kahi ākea ākea o nā noi a hiki ke hoʻokō i nā ʻano koi noiʻi ma nā kahua like ʻole.Mai kahi hiʻohiʻona hana, ʻo kekahi o nā mea maikaʻi o kēia maʻamau ʻo ia ka hōʻemi ʻana i ka manawa pili mechanical o nā pipeline i ka wā o ka hoʻonohonoho ʻana a me ka hoʻoponopono ʻana, a hiki ke hoʻonui nui i ka lōʻihi o nā pipeline i ka wā e hōʻoiaʻiʻo ana i ka pilina palekana, e hana palekana ai ka hana.
