1. Nau'in walda daban-daban:
Zamewa Kan Flanges: Ana amfani da weld na fillet don waldawa tsakanin bututun flange da flange.
Weld Neck Flanges: kabu waldi tsakanin flange da bututu ne kewaye weld.
2. Kayayyaki daban-daban:
Ana yin Slip On Flanges daga farantin karfe na yau da kullun tare da kauri wanda ya dace da buƙatun.
Weld Neck Flanges galibi ana yin injina daga jabun karfe.
3. Matsalolin sunaye daban-daban:
Matsin lamba na Slip A kan Flanges: 0.6 - 4.0MPa
Matsin lamba na Weld Neck Flanges: 1-25MPa
4.Tsarin daban-daban
Slip On Flanges: yana nufin flange wanda ke shimfida bututun karfe, kayan aikin bututu, da sauransu cikin flange kuma yana haɗa da kayan aiki ko bututu ta hanyar walda fillet.
Weld Neck Flanges: flange tare da wuyansa da canjin bututu, wanda aka haɗa tare da bututu ta hanyar waldawa.
5.Scope na aikace-aikace:
Slip On Flanges: yana dacewa da haɗin bututun ƙarfe tare da matsa lamba mara kyau wanda bai wuce 2.5MPa ba. Za'a iya yin sealing na flange guda uku: nau'in laushi, nau'in kamfani na kamfani da kuma nau'in Motsi. Aikace-aikacen flange mai santsi shine mafi girma Ana amfani da shi a cikin yanayin matsakaicin matsakaici, kamar ƙananan matsa lamba mara tsabtaccen iska da ƙarancin ruwa mai kewayawa.
Weld Neck Flanges: Ana amfani dashi don waldawar flanges da bututu. Tsarinsa yana da ma'ana, ƙarfinsa da ƙarfinsa suna da girma, yana iya jure yanayin zafi da matsa lamba mai yawa, maimaita lanƙwasawa da yanayin zafi, kuma hatiminsa abin dogaro ne. A wuya butt waldi flange da maras muhimmanci matsa lamba na 1.0 ~ 16.0MPa rungumi dabi'ar concave convex sealing surface.
Flange waldi na lebur za a iya haɗa shi kawai tare da bututu kuma ba za a iya haɗa shi kai tsaye tare da bututun walda ba; Za a iya haɗa flanges na butt-welding kai tsaye zuwa duk kayan aikin bututun walda (ciki har da gwiwar hannu, tees, bututu masu diamita daban-daban, da sauransu), kuma ba shakka, bututu.
Rigidity na wuyan butt walda flange ya fi na wuyan lebur waldi flange, da kuma butt waldi ƙarfi ya fi na lebur waldi flange, don haka ba shi da sauki yayyo.
Ba za a iya maye gurbin flange waldi na wuyan wuya da flange na butt walda ba yadda ake so. Dangane da masana'anta, flange waldi na wuyansa (SO flange) yana da babban warpage na ciki, ƙaramin nauyi da ƙarancin farashi. Bugu da kari, flange-welding na wuyan wuya tare da diamita na ƙididdiga sama da 250 mm (WN shine taƙaitaccen WELDINGCHECK) yana buƙatar gwadawa, don haka farashin yana da ɗan ƙaramin ƙarfi.
Ana amfani da walda mai lebur tare da wuya a ko'ina a cikin kayan aikin man fetur da aka shigo da su, kama da ma'aunin S0 na Amurka. Ana amfani da flanges-welding flanges don watsa labarai masu haɗari sosai.
Flange-welding na butt-welding yana nufin diamita na bututu da kauri na bangon ƙarshen haɗawa, wanda yake daidai da bututun da za a yi walda, kamar yadda ake waldasu bututu biyu.
Flange walda mai lebur wani dandali ne, rami na ciki ya fi diamita na bututun girma dan kadan, kuma ana saka bututun a cikin walda na ciki.
Lebur waldi da butt waldi suna nufin hanyoyin walda na flange da haɗin bututu. Lokacin walda flange waldi, kawai ana buƙatar waldi na gefe ɗaya, kuma babu buƙatar walda bututu da haɗin flange. A waldi da shigarwa na walda flange bukatar a welded a bangarorin biyu na flange. Saboda haka, lebur waldi flange ne kullum amfani ga low matsa lamba da matsakaicin matsa lamba bututu, da butt waldi flange da ake amfani da matsakaici da kuma high matsa lamba bututu dangane. Flange waldi gabaɗaya shine aƙalla PN2. 5 MPa, yi amfani da waldar gindi don rage damuwa. Gabaɗaya, flange waldi kuma ana kiransa babban flange na wuyansa tare da flange na wuyansa. Sabili da haka, farashin shigarwa, farashin aiki da farashin kayan taimako na flange waldi suna da girma, saboda akwai tsari ɗaya kawai don flange waldi.
