ʻO nā ʻano nui o nā gaskets flange
Nā gaskets ʻaʻole metala
Nā mea hana maʻamau: laholio, polytetrafluoroethylene (PTFE), olonā ʻole-asbestos (laholio asbestos).
Nā hoʻohana nui a me nā hiʻohiʻona:
I hoʻohana nui ʻia i ka wai, ka ea, ka mahu, ka waikawa a me ka alkali media, ʻo nā gaskets asbestos rubber kahi koho maʻamau i ka wā ma mua.
No nā kūlana kūpaʻa i ka corrosion, loaʻa i nā gaskets PTFE ke kūpaʻa kemika maikaʻi loa.
Nā gaskets semi-metala
Nā mea hana maʻamau: Kāʻei metala + kāʻei graphite/asbestos/PTFE i hoʻopiha ʻia (ʻano ʻeha), ʻiʻo metala ʻole i uhi ʻia me ka metala, gasket hui graphite palupalu.
Nā hoʻohana nui a me nā hiʻohiʻona:
Hoʻohui i ka ikaika o ka metala a me ka elasticity o ka mea ʻole metala i nā kūlana hana wela kiʻekiʻe, kaomi kiʻekiʻe a me nā kūlana hana loli. I waena o lākou, ʻo nā gaskets ʻeha metala ke koho nui i nā ʻoihana petrochemical, kemika a me nā ʻoihana ʻē aʻe.
No nā koi sila ikaika, e like me nā gaskets apo serrated/wavy metala, hoʻohana ʻia lākou i loko o nā pipeline a i ʻole nā kīʻaha kaomi me ke kaomi a me ka mahana kiʻekiʻe.
Nā gaskets metala
Nā mea maʻamau: kila akahai, kila kila, keleawe, Monel alloy.
Nā noi nui a me nā hiʻohiʻona:
Nā kūlana koʻikoʻi: hoʻohana ʻia i nā mea wela kiʻekiʻe, kaomi kiʻekiʻe a me nā mea ʻino loa.
Hāʻawi lākou i ka hana sila maikaʻi loa akā he mau koi kiʻekiʻe loa no ka pololei o ka hana ʻana o ka ʻili sila flange a me ke kau ʻana, a he pipiʻi hoʻi.
I ke koho ʻana i nā gaskets, pono e noʻonoʻo pono ʻia nā kumu he nui. Aia ke kumu i ʻehā mau kumu nui: "waena, kaomi, mahana, a me ka flange".
Nā waiwai waena: No nā mea ʻino (e like me nā waikawa a me nā alkalis), pono ke kūpaʻa ka mea gasket i ka pala.
Kaomi hana a me ka mahana: I nā kūlana wela a me ke kaomi kiʻekiʻe, pono e koho ʻia nā gaskets metala a i ʻole semi-metallic e hiki ke kū i ka mahana a me ke kaomi.
ʻAno ʻili sila flange: Pono e hoʻohālikelike ʻia nā ʻili flange like ʻole (e like me ke alo i hāpai ʻia RF, ke alo kāne a me ka wahine MFM, ke alo alelo a me ke awāwa TG) me nā ʻano gasket kikoʻī.
Nā kumu ʻē aʻe: Pono e noʻonoʻo ʻia ka haʻalulu, nā loli pinepine o ka mahana a me ke kaomi, ka pono no ka wehe pinepine ʻana, a me ka hoʻolālā kālā.
Ma keʻano holoʻokoʻa,
No ke kaomi haʻahaʻa a me nā mea maʻamau (wai, ea, mahu kaomi haʻahaʻa): Makemake ʻia nā gaskets ʻaʻole metala, e like me ka rubber a i ʻole PTFE gaskets, ma muli o ko lākou kumukūʻai kiʻekiʻe.
No ke kaomi waena a kiʻekiʻe paha, ke ana wela kiʻekiʻe a i ʻole nā kūlana hana paʻakikī (nā paipu i loko o nā ʻoihana petroleum, kemika a me ka mana): ʻO nā gaskets semi-metallic, ʻoi aku hoʻi nā gaskets i wahī ʻia me ka metala, ʻo ia ke koho maʻamau a hilinaʻi hoʻi.
No ke ana wela a me ke kaomi kiʻekiʻe loa a i ʻole nā kūlana ʻino ikaika: Pono e noʻonoʻo ʻia nā gaskets metala (e like me nā gaskets corrugated a i ʻole apo), akā he mea nui e hōʻoia i ka hoʻohālikelike kūpono o ka flange a me ke kau pololei ʻana.
