ʻO ka Flange Kuʻihao

Ua kapa ʻia ʻo Flange he flange a he flange paha.

ʻO ka ʻāpana e hoʻopili ai i ka paipu a me ka paipu kekahi i kekahi ua pili i ka hopena o ka paipu. Aia nā lua ma nā flanges, a ʻo nā bolts e hoʻopili pono i nā flanges ʻelua. Hoʻopaʻa ʻia nā flanges me nā gaskets. ʻO nā mea hoʻopili paipu flanged e pili ana i nā mea hoʻopili paipu me nā flanges (lugs a i ʻole sockets). Hiki ke hana ʻia ma ke hoʻolei ʻana (ʻaʻole i hōʻike ʻia ma ke kiʻi), a i ʻole hiki ke hana ʻia ma o ka pilina wili a i ʻole ka welding. ʻO ka pilina flange (flange, joint) he mau flanges, kahi gasket a me kekahi mau bolts a me nā nati. Hoʻonoho ʻia ka gasket ma waena o nā ʻili sila o nā flanges ʻelua. Ma hope o ka hoʻopaʻa ʻana i ka nati, hiki ke kaomi kikoʻī ma ka ʻili gasket i kahi waiwai a hoʻololi a hoʻopiha i ka ʻokoʻa o ka ʻili sila e hoʻopaʻa i ka pilina a pale i ka leak. ʻO ka pilina flange kahi pilina wehe. Wahi a nā ʻāpana i hoʻopili ʻia, hiki ke hoʻokaʻawale ʻia i ka flange ipu a me ka flange paipu. Wahi a ke ʻano o ke ʻano, aia nā flanges integral, nā flanges wehe a me nā flanges wili. ʻO nā flanges integral maʻamau e komo pū me nā flanges welding pālahalaha a me nā flanges welding butt. ʻO nā flanges i hoʻopaʻa ʻia me ka paʻakikī haʻahaʻa a kūpono no nā hanana me ke kaomi p≤4MPa; ua kapa ʻia hoʻi nā flanges butt-welded he flanges ʻāʻī kiʻekiʻe me ka paʻakikī nui a kūpono no nā hanana me ke kaomi a me ka mahana kiʻekiʻe. ʻEkolu ʻano o ka ʻili sila flange: ʻili sila pālahalaha, kūpono no nā hanana me ke kaomi haʻahaʻa a me nā mea ʻawaʻawa ʻole; ʻili sila concave-convex, kūpono no nā hanana me ke kaomi kiʻekiʻe iki; ʻili sila alelo a me ke awāwa, kūpono no nā mea lapalapa a me nā mea pahū, nā mea ʻawaʻawa a me nā manawa kaomi kiʻekiʻe. ʻO ka gasket he apo poepoe i hana ʻia me kahi mea hiki ke hana i ka deformation plastic a loaʻa kahi ikaika. ʻO ka hapa nui o nā gaskets i ʻoki ʻia mai nā papa ʻaʻole metala, a i ʻole i hana ʻia e nā hale hana ʻoihana e like me ka nui i kuhikuhi ʻia. ʻO nā mea hana he mau papa ʻōpala asbestos, nā papa asbestos, nā papa polyethylene, a pēlā aku; hoʻohana ʻia nā papa metala lahilahi (hao keʻokeʻo, kila kila) e wehe i ka asbestos. He gasket i wahī ʻia metala i hana ʻia me nā mea ʻaʻole metala; aia kekahi gasket ʻōwili i hana ʻia me ka lipine kila lahilahi a me ka lipine asbestos. He kūpono nā gaskets rapa maʻamau no nā hanana i emi ai ka mahana ma mua o 120°C; kūpono nā gaskets rapa asbestos no nā hanana i emi ai ka mahana o ka mahu wai ma mua o 450°C, emi ka mahana o ka ʻaila ma mua o 350°C, a emi ke kaomi ma mua o 5MPa, a he mea ʻino ia. ʻO ka mea maʻamau i hoʻohana ʻia, ʻo ia ka papa asbestos kūpaʻa i ka waikawa. I loko o nā lako a me nā paipu kaomi kiʻekiʻe, hoʻohana ʻia nā gaskets metala o ke ʻano lens a i ʻole nā ​​​​ʻano ʻē aʻe i hana ʻia me ke keleawe, ka alumini, ke kila No. 10, a me ke kila kila. He haiki loa ka laulā pili ma waena o ka gasket kaomi kiʻekiʻe a me ka ʻili sila (pili laina), a kiʻekiʻe ka hoʻopau ʻana o ka ʻili sila a me ka gasket.

Ua māhele ʻia ka flange i loko o ka flange pili wili (pili uea), ka flange wili a me ka flange hoʻopaʻa. Aia nā flanges uea a me nā flanges ferrule no nā diameters liʻiliʻi haʻahaʻa. Hoʻohana ʻia nā flanges wili ʻia no nā diameters nui kiʻekiʻe a me ke kaomi haʻahaʻa. ʻOkoʻa ka mānoanoa o nā flanges a me ke anawaena a me ka helu o nā bolts hoʻohui no nā kaomi like ʻole.
