He kuleana koʻikoʻi nā Flanges i nā ʻoihana like ʻole, e hana ana i nā ʻāpana hoʻohui e hiki ai i ka hui maʻalahi a me ka wehe ʻana o nā ʻōnaehana paipu. Inā he ʻenekinia ʻoihana ʻoe a makemake wale paha e pili ana i ka mīkini o nā flanges, eia kēia blog e hāʻawi iā ʻoe i kahi ʻike hohonu o kā lākou mau ʻano a me nā ʻano like ʻole. No laila e luʻu kākou!
Nā hiʻohiʻona o nā Flanges:
Loaʻa i nā flanges kekahi mau hiʻohiʻona koʻikoʻi e kūpono iā lākou no kā lākou noi i manaʻo ʻia. ʻO ka mea mua, koho ʻia kā lākou mau mea hana no ko lākou ikaika kiʻekiʻe, e like me ke kila kalapona, ke kila kila, a i ʻole ke kila kila. Mālama kēia i ka lōʻihi a me ke kūpaʻa ʻana i nā kaiapuni corrosive like ʻole. Hoʻohui ʻia, hoʻolālā ʻia nā flanges e kū i ke kaomi kiʻekiʻe, e hoʻolilo iā lākou i mau mea pono i nā ʻoihana e pili ana i nā ʻōnaehana wai a i ʻole nā ea. Eia kekahi, ʻike ʻia nā flanges no kā lākou mau waiwai sila maikaʻi loa, ka pale ʻana i ka leakage a me ka hōʻoia ʻana i ka pono o nā pilina paipu.
Nā ʻano o nā flanges:
1. Hoʻohui pū (IF):
ʻO ka flange integral, i ʻike ʻia ʻo IF, he ʻāpana ʻāpana i hana ʻia a hoʻolei ʻia me ka paipu. ʻAʻole ia e koi i ka wili hou, e lilo ia i koho kaulana no nā paipu liʻiliʻi a i ʻole nā ʻōnaehana haʻahaʻa haʻahaʻa.
2. Laulā Uila (Th):
Loaʻa i nā flanges i hoʻopaʻa ʻia he mau milo kūloko e hiki ai iā lākou ke wili ʻia ma luna o ka hopena paipu kaula. Hoʻohana pinepine ʻia lākou i nā ʻōnaehana haʻahaʻa haʻahaʻa a i ʻole ke koi ʻia ka wehe pinepine ʻana.
3. Pāpaʻa Paʻa Welding Flange (PL):
Hoʻopili pololei ʻia ka flange welding plate-flat, i kapa ʻia ʻo PL, i ka hopena paipu, e hōʻoia ana i kahi pilina paʻa a leak-proof. Hoʻohana maʻamau ia i nā ʻoihana kahi e pono ai ke komo maʻalahi no ka nānā ʻana a hoʻomaʻemaʻe paha.
4. ʻAi Kuʻi Kuʻekuʻe me ke Anawaena (WN):
Hoʻohana ʻia nā flanges welding butt me ke anawaena, i kapa ʻia ʻo WN, i nā noi kiʻekiʻe a me nā noi koʻikoʻi kahi o ka ikaika o ka hui. ʻO ke kaʻina hana hoʻoheheʻe e pili ana i ka hoʻopili pololei ʻana i ka paipu a me ka flange, e hāʻawi ana i ka ikaika kupaianaha a me ka hilinaʻi.
5. Paʻa Welding Flange me ka ʻāʻī (SO):
ʻO nā flanges welding flat me nā ʻāʻī, a i ʻole SO flanges, e hōʻike ana i ka ʻāʻī i hoʻokiʻekiʻe ʻia e kōkua i ka hoʻoikaika ʻana i ka ikaika a hāʻawi i ka hoʻonui ʻana i ke kūʻē ʻana i nā ikaika kulou. Hoʻohana pinepine ʻia kēia mau flanges i nā ʻoihana e koi ana i nā kūlana kiʻekiʻe.
6. Hoʻoheheʻe Welding Flange (SW):
Hoʻolālā ʻia nā flanges socket welding, a i ʻole SW flanges, no nā paipu liʻiliʻi a me nā ʻōnaehana kiʻekiʻe. Hāʻawi lākou i kahi kumu e hiki ai ke hoʻokomo i ka paipu, e hāʻawi ana i kahi pilina paʻa a paʻa.
7. Ke apo kuʻekuʻe wāwae ʻaloʻalo (PJ/SE):
ʻElua mau ʻāpana ʻokoʻa i loko o ke apo wili puʻupuʻu, i kapa ʻia ʻo PJ/SE flange: ʻo ka flange wehe a me kahi ʻāʻī weld stub-end. Hiki i kēia ʻano flange ke maʻalahi i ka hoʻonohonoho ʻana, e hōʻemi ana i ka manawa o nā kuhi hewa.

ʻO ke apo kuʻikuʻi paʻa paʻa ʻole, ʻike ʻia ʻo PJ/RJ flanges, hāʻawi i nā mea maikaʻi e like me nā flanges PJ/SE, akā ʻaʻole lākou he ʻāʻī. Akā, ua hoʻopili pololeiʻia lākou i ka paipu, e hōʻoia ana i kahi hui paʻa.
9. Uhi Flange Laina (BL(S)):
ʻO nā pale flange laina, a i ʻole BL (S) flanges, he mau flanges kūikawā i hoʻohana ʻia i nā kaiapuni corrosive. Hele mai kēia mau flanges me kahi liner pale e pale ai i ka media corrosive mai ka hoʻopili pololei ʻana me ka mea flange, e hoʻolōʻihi i ko lākou ola.
10. Uhi Flange (BL):
Hoʻohana ʻia nā uhi flange, ʻike wale ʻia ʻo BL flanges, e hoʻopaʻa i ka hopena paipu ke hoʻohana ʻole ʻia. He kūpono lākou no nā noi kahi e pono ai ka wehe ʻana i kahi manawa, e hāʻawi ana i kahi pale pale i ka lepo, nā ʻōpala, a me nā mea haumia ʻē aʻe.
Ka hopena:
I ka hopena, he mau mea koʻikoʻi nā flanges i nā ʻoihana he nui, e hāʻawi ana i kahi pilina hilinaʻi ma waena o nā paipu a me ka hōʻoia i ka pono a me ka palekana o nā ʻōnaehana wai a me nā kinoea. He mea nui ka hoʻomaopopo ʻana i nā hiʻohiʻona a me nā ʻano flanges like ʻole i ke koho ʻana i ka mea kūpono no kahi noi i hāʻawi ʻia. Hāʻawi kēlā me kēia ʻano flange i nā pono kūikawā e pili ana i nā koi kikoʻī o ka ʻōnaehana. Me kēia ʻike, hiki i nā ʻenekinia a me nā poʻe like ke koho me ka hilinaʻi i ka flange kūpono no kā lākou pono, e hōʻoia i ka hana maikaʻi loa a me nā pilina lōʻihi.
