Flange Classification:
1. Cov ntaub ntawv flange: carbon steel, cam khwb cia hlau, hlau alloy, stainless hlau, tooj liab thiab txhuas alloy.
2. Los ntawm txoj kev tsim khoom, nws tuaj yeem muab faib ua forged flange, cam khwb cia flange, welded flange, thiab lwm yam.
3. Raws li cov txheej txheem tsim khoom, nws tuaj yeem muab faib ua tus qauv hauv tebchaws (GB) (Tsoomfwv kev lag luam chemical, qauv roj av, hluav taws xob hluav taws xob), American Standard (ASTM), German standard (DIN), Japanese standard (JB) , lwm.
Lub teb chaws tus qauv ntawm cov yeeb nkab flanges hauv Suav teb yog GB.
Lub Flange Nominal Siab: 0.25mpa-42.0mpa.
Series 1: PN1.0, PN1.6, PN2.0, PN5.0, PN10.0, PN15.0, PN25.0, PN42 (lub ntsiab series).
Series ob: PN0.25, PN0.6, PN2.5, PN4.0.
Flange Structural Form:
ib.Pav ca vuam flange PL;
b.Pav ca vuam nrog caj dab SO;
c.Lub taub qab vuam flange WN;
d.Qhov (socket) weld flange SW;
e. Xaws flangePJ/SE;
f.Integral raj IF;
g.Threaded flange TH;
h.Flange npog BL, ob sab flange npog BL (S).
Flange Sealing Nto Hom:dav hlau FF, tsa saum npoo RF, concave nto FM, convex nto MF, tus nplaig thiab zawj nto TG, nplhaib kev sib txuas nto RJ.
Daim ntawv thov Flange
Flat welded steel flange:haum rau carbon steel yeeb nkab txuas nrog nominal siab tsis tshaj 2.5Mpa.Lub sealing nto ntawm lub tiaj vuam flange tuaj yeem ua rau peb hom: hom du, concave-convex hom thiab hom nplaig-thiab-groove.Daim ntawv thov ntawm lub tiaj tiaj vuam flange yog qhov loj tshaj plaws, thiab feem ntau yog siv nyob rau hauv cov ntaub ntawv ntawm nruab nrab nruab nrab tej yam kev mob, xws li low-pressure unpurified compressed cua thiab low-pressure circulating dej.Nws qhov zoo dua yog tias tus nqi pheej yig heev.
Lub taub qab vuam steel flange:Nws yog siv rau pob tw welding ntawm flange thiab yeeb nkab.Nws muaj cov qauv tsim nyog, lub zog siab thiab rigidity, tuaj yeem tiv taus qhov kub thiab txias, rov kho dua thiab kub hloov pauv, thiab muaj kev ruaj ntseg sealing kev ua tau zoo.Lub taub qab vuam flange nrog lub nominal siab ntawm 0.25-2.5Mpa txais lub concave-convex sealing nto.
Qhov (socket) vuam flange:feem ntau siv hauv cov kav dej nrog PN≤10.0Mpa thiab DN≤40;
Loose flanges:xoob flanges feem ntau hu ua looper flanges, phua vuam nplhaib looper flanges, flanging looper flanges thiab taub qab vuam looper flanges.Nws yog feem ntau siv nyob rau hauv rooj plaub uas qhov nruab nrab kub thiab siab tsis siab thiab qhov nruab nrab yog ntau corrosive.Thaum qhov nruab nrab yog corrosive ntau dua, ib feem ntawm flange hu rau nruab nrab (flanging luv sib koom ua ke) yog ua los ntawm qib siab corrosion-resistant cov ntaub ntawv xws li stainless hlau, thiab sab nraud yog clamped los ntawm flange rings ntawm cov ntaub ntawv qib qis xws li carbon hlau.kom ua tiav sealing;
Integral flange:Lub flange feem ntau ua ke nrog cov khoom siv, cov kav dej, li qub, thiab lwm yam. Hom no feem ntau siv rau hauv cov khoom siv thiab cov li qub.
