ʻO nā flanges i hoʻopaʻa ʻiahana ʻia ma ke kumu o ka hoʻoleinā lepa kila, a ua oi aku ko lakou ikaika mamua o ka hooleiianā lepa kila, no laila ua pili nā ʻāpana i pili me nā paipu i ka hopena paipu.ʻO ka flange welding buttHe ʻano paipu kūpono, e pili ana i ka flange me ka ʻāʻī a me ka hoʻololi ʻana o ka paipu pōʻai a me ka pilina kuʻi ʻana me ka paipu. ʻAʻole maʻalahi ka deformation, hoʻopaʻa maikaʻi, hoʻohana nui ʻia, kūpono no ka piʻi ʻana a i ʻole ka hoʻololi ʻana o ka mahana o nā pipelines a i ʻole ke kiʻekiʻe kiʻekiʻe, ke kiʻekiʻe kiʻekiʻe a me nā pipeline haʻahaʻa haʻahaʻa, ʻoi aku ka maikaʻi o ka maikaʻi, ʻaʻole ʻoi aku ka nui o ke kaomi nominal ma mua o 2.5mpa; Hoʻohana ʻia ia no ka lawe ʻana i ka media pipiʻi, flammable a pahū ma ka pipeline, a ʻo ke kaomi nominal e pili ana iā PN16MPa.
ʻO kahoʻopunipuniua ʻae ʻia nā flanges, a ʻo nā bolts (ʻo ia ke poʻo a me ka screw) e hoʻopaʻa i nā ʻaoʻao ʻelua. Hoʻopaʻa ʻia nā flanges forged me nā gaskets.Hoʻopaʻa ʻiapili nā paipu i nā mea menā lau i hoʻopaʻa ʻia (flangesa i ʻole nā ​​hono). Hiki ke hoʻolei ʻia, wili a welded paha. ʻO ka pilina o ka flange he mau flanges, kahi gasket a me kekahi mau bolts a me nā nati. Hoʻokomo ʻia ka gasket ma waena o nā ʻāpana hoʻopaʻa ʻana o nā flanges ʻelua, a ma hope o ka hoʻopaʻa ʻana i ka makuahine screw, ua deformed ke kaomi kikoʻī ma ka ʻili o ka gasket ma hope o ka hiki ʻana i kahi waiwai, a hoʻopiha ʻia ka wahi ʻole ma ka ʻili hoʻopaʻa, no laila ua hoʻopiha ʻia ka pahu. paʻa a leakproof ka pilina.

ʻEkolu ʻano o ka forging flange sealing surface: plane sealing surface, kūpono no ke kaomi ʻaʻole kiʻekiʻe, medium (decisive substance) non-toxic occasions; Concave a convex sealing surface, kūpono no nā manawa kiʻekiʻe iki; Hoʻopaʻa ʻia ka ʻili o ka ʻūhā (S ǔ N), kūpono no nā manawa pahū, pahū, mea ʻawaʻawa a me nā manawa piʻi kiʻekiʻe. ʻO Gasket kahi apo i hana ʻia me ka Material hiki ke hana i ka deformation plastic a loaʻa kekahi ikaika.
ʻO ka hapa nui o nā gaskets i ʻoki ʻia mai nā papa non-metallic, a i hana ʻia e nā hale hana ʻoihana e like me ka nui i ʻōlelo ʻia (GU ī ding), ʻo ka Material he asbestos Rubber papa, asbestos board, polyethylene board, etc. , kila kuhiliʻole) asbestos a me nā mea metala ʻole ʻē aʻe i wahī ʻia me ka gasket metala; Aia kekahi ʻano o ka wili i hana ʻia me ke kāʻei kila lahilahi a me ke kāʻei asbestos pū kekahi. Kapa ʻia ʻo Flange flange. Hoʻopili ʻia ka ʻāpana e hoʻopili ai i ka paipu i ka paipu i ka hopena paipu. Aia nā puka i loko o ka flange a paʻa nā bolts i nā ʻaoʻao ʻelua. Hoʻopaʻa paʻa ma waena o nā flanges. ʻO Flange kahi ʻāpana ʻano diski, ʻoi aku ka maʻamau i ka ʻenehana pipeline. Hoʻohana ʻia nā flanges i ʻelua.

I ka ʻenehana pipeline, hoʻohana nui ʻia ka flange no ka pilina pipeline. I ka hopena kahi e pono ai e hoʻopili ʻia nā paipu ʻelua, e kau i kahi flange no kēlā me kēia. Hiki ke hoʻohana ʻia ka flange uea no nā paipu haʻahaʻa haʻahaʻa, a hiki ke hoʻohana ʻia ka flange welded no ke kaomi ʻoi aku ma mua o 4 kg. E kau i ka pahu ma waena o nā flannel ʻelua a hoʻopaʻa iā lākou i lalo. Hoʻohana maʻamau nā mea hana Flange i nā bolts e hoʻopili i nā mokulele ʻelua ma ka ʻaoʻao i ka manawa like i pani ʻia nā ʻāpana pili, i ʻike nui ʻia ʻo "flange", e like me ka pilina paipu ventilation, hiki ke kapa ʻia kēia ʻano ʻāpana "nā ʻāpana flange". He kūpono ke kīpē maʻamau no ka manawa i emi iho ka mahana ma mua o 120 ℃; He mea kūpono ka asbestos rubber gasket no ka mahu wai (i kapa ʻia ʻo ka wai wai) ma lalo o 450 ℃, ʻoi aku ka mahana o ka aila ma lalo o 350 ℃, ʻoi aku ke kaomi ma mua o 5MPa mau manawa, no ke ʻano corrosive maʻamau (e pāʻani i kahi kuleana koʻikoʻi i ka mea. ), ʻoi aku ka maʻamau i hoʻohana ʻia ʻo ia ka pā asbestos kūpaʻa i ka waikawa. I loko o ke kiʻekiʻe puʻe lako (SHEBEI) a me ka paipu, metala gaskets o ke keleawe, aluminika (Al), no. 10 kila, kila kuhiliʻole (stainless acid resistant steel) i hana ʻia me ka lens (ka hoʻokaʻawale ʻana: lens plastic a me ka lens aniani ʻelua ʻano) a i ʻole nā ​​ʻano ʻē aʻe. ʻO ka laula hoʻopili o ka ʻili puʻe kiʻekiʻe a me ka ili hoʻopaʻa he haiki loa (linear contact), a ʻoi aku ka kiʻekiʻe o ka hoʻopau ʻana o ka ili a me ka gasket.
