ʻO ka flange ʻōwili anu he ʻano flange i hoʻohana mau ʻia i ka pilina pipeline, ʻike ʻia hoʻi he flange ʻōwili anuanu. Ke hoʻohālikelike ʻia me nā flanges forged, ʻoi aku ka haʻahaʻa o kāna kumukūʻai hana, akā ʻaʻole i emi kona ikaika a me ka hana hoʻopaʻa ʻana i nā flanges forged. Hiki ke hoʻohana i nā flanges ʻōwili anuanu i nā ʻano flanges like ʻole, mepā flanges, wiliwili puʻupuʻu, nā lepa wili, etc. No laila, hoʻohana nui ʻia i nā ʻōnaehana ʻoihana a me nā ʻōnaehana kīwila.
He kūpono nā flanges ʻōwili anuanu no nā ʻano pili pipeline like ʻole, me ka petrochemical, ka hana moku, ka mālama ʻana i ka wai, ka hoʻomehana a me ka ea, ka lako wai o ke kūlanakauhale a me nā māla ʻē aʻe. ʻO nā mea maikaʻi o ka hana ʻana i ka flange cold rolled ʻo kāna kaʻina hana maʻalahi, haʻahaʻa haʻahaʻa, a pili i nā ʻano mea like ʻole a me nā paipu mānoanoa, no laila ua hoʻohana nui ʻia.
ʻO ke kaʻina hana o ka flange i ʻōwili ʻia ma ke kuʻi ʻana i ka pā kila i loko o ka pōʻai a hoʻopaʻa ʻia nā ʻaoʻao ʻelua a lilo i apo. Ua kapa ʻia kēia ʻano kuʻi ʻana i ka welding girth, a hiki ke hoʻopaʻa lima a i ʻole ke kuʻi ʻana. Hiki ke hana ʻia nā flanges i ʻōwili ʻia e like me nā nui maʻamau, a hiki ke hana ʻia nā flanges maʻamau ʻole e like me nā pono o ka mea kūʻai aku.
ʻO ka ʻenehana hana o ka hoʻolei ʻana i ka flange wili anu: e hoʻokomo i ke kila maka i koho ʻia i loko o ka umu uila no ka hoʻoheheʻe ʻana, i hiki ai ka mahana o ke kila hoʻoheheʻe ʻia i 1600-1700 ℃; Hoʻomaʻamaʻa mua ʻia ka pahu metala i 800-900 ℃ e mālama i kahi mahana mau; E hoʻomaka i ka centrifuge a hoʻokomo i ke kila i hoʻoheheʻe ʻia i loko o ka pahu metala preheated; Hoʻomaʻalili maoli ka hoʻolei ʻana i 800-900 ℃ no 1-10 mau minuke; E hooluolu me ka wai a kokoke i ka wela o ka lumi, e wehe i ka poni a lawe i ka hoolei.
ʻO nā mea maikaʻi o nā flanges i ʻōwili ʻia me ka haʻahaʻa o ka hana ʻana, ka hana maʻalahi a me ka hoʻokomo ʻana, ka pale ʻana i ka corrosion maikaʻi, a me ke kaumaha māmā. Eia nō naʻe, ke hoʻohālikelike ʻia me nā flanges forged, ʻoi aku ka maikaʻi o ka ikaika a me ka hana hoʻopaʻa ʻana o nā flanges ʻōwili anuanu. No laila, ma kekahi mau noi kiʻekiʻe a i ʻole ka wela wela, pono nō e hoʻohana i nā flanges forged a i ʻole nā pili paipu i hoʻoikaika ʻia.
