Forged flangesyog invented nyob rau hauv lub hauv paus ntawm cam khwb ciahlau flanges, thiab lawv lub zog ntau dua li cam khwb ciahlau flanges, kom cov khoom txuas nrog cov kav dej txuas nrog cov yeeb nkab kawg.Lub taub qab vuam flangeyog ib hom yeeb nkab haum, uas yog hais txog flange nrog lub caj dab thiab ib puag ncig cov yeeb nkab hloov thiab taub qab vuam txuas nrog cov yeeb nkab. Nws tsis yooj yim rau deformation, zoo sealing, dav siv, haum rau siab los yog kub hloov ntawm cov kav dej los yog kub kub, siab siab thiab kub tsis kub pipelines, qhov zoo dua yog pheej yig dua, nominal siab tsis tshaj 2.5mpa; Nws kuj yog siv rau kev xa cov khoom kim heev, flammable thiab explosive media ntawm lub raj xa dej, thiab lub nominal siab yog hais txog PN16MPa.
Covforgedflanges yog perforated, thiab cov bolts (muaj lub taub hau thiab ntsia hlau) tuav ob flanges ua ke. Lub forged flanges yog kaw nrog gaskets.Forged flangedyeeb nkab fittings xa mus rau cov nrogforged flanges (flangeslos yog pob qij txha). Nws tuaj yeem raug cam khwb cia, threaded lossis welded. Lub flange kev twb kev txuas muaj ib khub ntawm flanges, ib tug gasket thiab ib tug xov tooj ntawm bolts thiab ceev. Lub gasket yog muab tso rau nruab nrab ntawm lub sealing nto ntawm ob lub flanges, thiab tom qab zawm cov ntsia hlau niam, lub siab tshwj xeeb ntawm lub gasket yog deformed tom qab ncav cuag ib tug nqi, thiab qhov chaw tsis sib xws ntawm lub sealing nto yog ntim, thiaj li hais tias lub sealing nto yog deformed. kev sib txuas yog nruj thiab leakproof.

Muaj peb hom forging flange sealing nto: dav hlau sealing nto, haum rau lub siab tsis siab, nruab nrab (cov khoom txiav txim siab) tsis muaj tshuaj lom; Concave thiab convex sealing nto, haum rau me ntsis siab dua zaus; Sealing nto ntawm tenon (S ǔ N) zawj, haum rau cov nplaim taws, tawg, muaj tshuaj lom nruab nrab thiab lub sijhawm siab. Gasket yog lub nplhaib ua los ntawm Cov Khoom Siv uas tuaj yeem tsim cov yas deformation thiab muaj lub zog muaj zog.
Feem ntau cov gaskets raug txiav los ntawm cov hlau tsis yog hlau, los yog ua los ntawm cov chaw tsim khoom raws li qhov loj me (GU ī ding), Cov Khoom Siv yog asbestos Rubber board, asbestos board, polyethylene board, thiab lwm yam. Thiab tseem siv tau nyias hlau phaj (hlau ntawv , stainless hlau) asbestos thiab lwm yam khoom siv tsis yog xim hlau qhwv los ntawm cov hlau gasket; Tseem muaj ib hom winding gasket ua los ntawm nyias steel siv thiab asbestos siv ua ke. Flange tseem hu ua flange flange. Qhov chaw uas txuas cov yeeb nkab mus rau cov yeeb nkab yog txuas nrog cov yeeb nkab kawg. Muaj qhov nyob hauv flange thiab bolts tuav ob lub flanges ua ke. Gasket seals ntawm flanges. Flange yog ib feem ntawm daim disk, uas yog ntau dua nyob rau hauv pipeline engineering. Flanges yog siv ua khub.

Hauv pipeline engineering, flange feem ntau yog siv rau kev sib txuas ntawm cov kav dej. Thaum kawg qhov twg ob lub kav dej yuav tsum tau txuas, nruab ib lub flange rau txhua tus. Hlau flange tuaj yeem siv rau cov kav dej uas tsis tshua muaj siab, thiab welded flange tuaj yeem siv rau siab tshaj 4 kg. Muab lub gasket nruab nrab ntawm ob lub flannels thiab ntsia liaj qhov rooj. Flange manufacturers feem ntau siv bolts los txuas rau ob lub dav hlau nyob rau hauv lub periphery nyob rau tib lub sij hawm kaw qhov kev twb kev txuas qhov chaw, feem ntau hu ua "flange", xws li qhov cua yeeb nkab kev twb kev txuas, qhov zoo ntawm no yuav hu ua "flange qhov chaw". Cov roj hmab gasket yog tsim rau lub sijhawm uas qhov kub thiab txias qis dua 120 ℃; Asbestos roj hmab gasket yog haum rau dej vapor (xws li dej vapor) kub yog tsawg dua 450 ℃, roj kub yog tsawg dua 350 ℃, siab tsawg dua 5MPa zaus, rau qhov nruab nrab corrosive (ua lub luag haujlwm txiav txim siab hauv cov khoom siv. ), feem ntau siv yog acid resistant asbestos phaj. Hauv cov cuab yeej siv siab siab (SHEBEI) thiab cov kav dej, hlau gaskets ntawm tooj liab, txhuas (Al), tsis muaj. 10 steel, stainless hlau (stainless acid resistant steel) ua los ntawm lub lens (kev faib tawm: yas lens thiab iav lens ob yam) los yog lwm yam duab. Kev sib cuag dav ntawm lub siab-siab gasket thiab sealing nto yog nqaim heev (linear contact), thiab kev ua tiav ntawm sealing nto thiab gasket yog qhov siab.
