Flange Gasket

Gasket yog lub nplhaib ua los ntawm cov khoom siv uas tuaj yeem tsim cov yas deformation thiab muaj lub zog zoo. 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 ntau thiab tsawg. Cov ntaub ntawv yog cov ntaub ntawv roj hmab asbestos, cov ntawv asbestos, PTFE ntawv, polyethylene los xij, thiab lwm yam. Tseem muaj cov hlau-clad gaskets ua los ntawm wrapping non-metallic cov ntaub ntawv xws li asbestos nrog nyias hlau los xij (tinplate, stainless hlau); Kuj tseem muaj qhov txhab gasket ua los ntawm cov hlau nyias nyias thiab asbestos strips. Feem ntau siv yog cov hlau qhov txhab gasket ua los ntawm stainless hlau strips thiab graphite. Nyob ntawm kev siv ib puag ncig, daim kab xev winding tuaj yeem ua los ntawm asbestos. Cov roj hmab zoo tib yam yog tsim rau lub sijhawm uas kub qis dua 120 degree; asbestos roj hmab gaskets yog tsim rau cov dej vapor kub hauv qab 450 degree, roj kub hauv qab 350 degree, thiab pressures hauv qab 5MPa. Rau cov xov xwm corrosive, feem ntau siv yog acid-resistant asbestos nplooj ntawv. Hauv cov khoom siv hluav taws xob siab thiab cov kav dej, lub lens-shaped lossis lwm yam zoo li cov hlau gaskets ua los ntawm tooj liab, aluminium, No. 10 steel, thiab stainless hlau yog siv. Kev sib cuag dav ntawm lub siab-siab gasket thiab sealing nto yog nqaim heev (kab sib cuag), thiab kev ua tiav ntawm sealing nto thiab lub gasket yog siab heev.
Tsawg-siab me-inch flanges muaj threaded flanges, thiab high-pressure thiab low-pressure loj-inch flanges siv welded flanges. Lub thickness ntawm flanges ntawm txawv pressures thiab txoj kab uas hla thiab tus naj npawb ntawm txuas bolts yog txawv.
