Lub flanged sib koom yog ib qho kev sib koom ua ke. Muaj qhov nyob hauv lub flange, bolts tuaj yeem hnav los ua kom ob lub flanges nruj nreem txuas, thiab cov flanges raug kaw nrog gaskets. Raws li cov khoom sib txuas, nws tuaj yeem muab faib ua lub thawv flange thiab cov yeeb nkab flange. Cov yeeb nkab flange tuaj yeem muab faib ua tsib hom raws li kev sib txuas nrog cov yeeb nkab: tiaj vuam flange, taub qab vuam flange, xov flange, lub qhov (socket) vuam flange, xoob flange.

■Flat vuam flange

Pav ca welded steel flange: haum rau carbon steel yeeb nkab txuas nrog nominal siab tsis tshaj 2.5MPa. Lub sealing nto ntawm tiaj welded flange tuaj yeem ua rau peb hom: hom du, concave thiab convex thiab grooved hom. Smooth hom tiaj welded flange Daim ntawv thov yog qhov loj tshaj plaws. Nws yog feem ntau yog siv nyob rau hauv cov ntaub ntawv ntawm nruab nrab xov xwm tej yam kev mob, xws li tsis tshua muaj siab tsis-purified compressed cua thiab tsis tshua muaj siab circulating dej. Nws qhov zoo dua yog tias tus nqi pheej yig heev.

■Lub taub qab vuam flange

Butt welding flange: Nws yog siv rau qhov sib txawv vuam ntawm flange thiab yeeb nkab. Nws cov qauv tsim nyog, nws lub zog thiab rigidity yog qhov loj, nws tuaj yeem tiv taus qhov kub thiab txias siab thiab rov kho dua thiab kub hloov pauv. Lub sealing kev ua tau zoo yog txhim khu kev qha. Lub nominal siab yog 0.25 ~ 2.5MPa. Vuam flange nrog concave thiab convex sealing nto

■Qhov (socket) vuam flange

Qhov (socket) vuam flange: feem ntau siv hauv PN10.0MPa, DN40 pipeline

■ Loose flange (feem ntau hu ua looper flange)

Butt welding tes tsho flange: Nws yog feem ntau siv thaum nruab nrab kub thiab siab tsis siab thiab qhov nruab nrab yog corrosive. Thaum qhov nruab nrab yog corrosive, ib feem ntawm lub flange uas hu rau nruab nrab (flange luv ntu) yog cov khoom siv qib siab corrosion-resistant xws li steel, thaum sab nraud yog clamped los ntawm flange nplhaib ntawm cov khoom qis xws li carbon hlau. Nws mus cuag ib lub foob

■ Integral flange

Integral flange: Nws feem ntau yog kev sib koom ua ke ntawm flanges nrog cov khoom siv, cov kav dej, fittings, li qub, thiab lwm yam. Hom no feem ntau siv rau cov khoom siv thiab cov li qub.
