Cov kev siv thiab hom flange gaskets

Cov hom tseem ceeb ntawm flange gaskets

Cov gaskets uas tsis yog hlau

Cov ntaub ntawv ib txwm muaj: roj hmab, polytetrafluoroethylene (PTFE), cov fiber tsis yog asbestos (roj hmab asbestos).

Cov kev siv tseem ceeb thiab cov yam ntxwv:

Siv dav hauv dej, cua, pa, kua qaub thiab alkali media, roj hmab asbestos gaskets yog ib qho kev xaiv dav dav.

Rau cov xwm txheej uas tiv taus corrosion, PTFE gaskets muaj kev ruaj khov tshuaj zoo heev.

Cov gaskets semi-metallic

Cov ntaub ntawv ib txwm muaj: Hlau band + graphite/asbestos/PTFE-filled band (hom qhov txhab), hlau-clad non-metallic core, flexible graphite composite gasket.

Cov kev siv tseem ceeb thiab cov yam ntxwv:

Ua ke lub zog ntawm cov hlau thiab qhov elasticity ntawm cov hlau tsis yog hlau hauv qhov kub siab, siab siab thiab hloov pauv ntawm cov xwm txheej ua haujlwm. Ntawm lawv, cov gaskets hlau yog qhov kev xaiv tseem ceeb hauv petrochemical, tshuaj lom neeg thiab lwm yam lag luam.

Rau cov kev cai sealing muaj zog, xws li cov hlau serrated / wavy ring gaskets, lawv siv rau hauv cov kav dej lossis cov hlab siab nrog siab dua thiab kub.

Cov gaskets hlau

Cov ntaub ntawv ib txwm muaj: hlau tsis muaj zog, hlau tsis xeb, tooj liab, Monel alloy.

Cov ntawv thov tseem ceeb thiab cov yam ntxwv:

Cov xwm txheej hnyav heev: siv rau hauv qhov kub thiab txias, siab thiab corrosive heev.

Lawv muaj kev ua haujlwm zoo heev tab sis muaj qhov yuav tsum tau ua kom raug ntawm qhov flange sealing nto thiab kev teeb tsa, thiab kim heev.

Thaum xaiv cov gaskets, ntau yam yuav tsum tau xav txog kom meej. Lub hauv paus ntsiab lus nyob rau hauv plaub lub ntsiab lus tseem ceeb: "nruab nrab, siab, kub, thiab flange".

Cov khoom nruab nrab: Rau cov xov xwm corrosive (xws li cov kua qaub thiab alkalis), cov khoom siv gasket yuav tsum tiv taus corrosion.

Kev ua haujlwm siab thiab kub: Hauv qhov kub thiab txias thiab siab, yuav tsum xaiv cov hlau lossis semi-metallic gaskets uas tuaj yeem tiv taus kub thiab siab.

Hom nto ntawm flange sealing: Cov nto flange sib txawv (xws li lub ntsej muag tsa RF, lub ntsej muag txiv neej thiab poj niam MFM, lub ntsej muag nplaig thiab qhov zawj TG) yuav tsum tau phim nrog cov hom gasket tshwj xeeb.

Lwm yam tseem ceeb: Kev co, kev hloov pauv ntau zaus ntawm qhov kub thiab txias thiab siab, qhov xav tau kev rhuav tshem ntau zaus, thiab cov peev nyiaj siv kuj yuav tsum tau xav txog.

Zuag qhia tag nrho,

Rau cov khoom siv uas tsis muaj zog thiab cov khoom siv uas siv ntau (dej, cua, pa dej uas tsis muaj zog): Cov gaskets uas tsis yog hlau, xws li roj hmab lossis PTFE gaskets, yog cov uas nyiam siv vim lawv pheej yig.

Rau qhov nruab nrab mus rau qhov siab, qhov kub siab lossis cov xwm txheej ua haujlwm nyuaj (cov kav dej hauv cov roj av, tshuaj lom neeg thiab fais fab): Cov gaskets semi-metallic, tshwj xeeb tshaj yog cov gaskets hlau-kub, yog qhov kev xaiv feem ntau thiab txhim khu kev qha.

Rau qhov kub thiab txias heev lossis cov xwm txheej corrosive muaj zog: Yuav tsum xav txog cov gaskets hlau (xws li corrugated lossis ring gaskets), tab sis nws yog qhov tseem ceeb kom ntseeg tau tias flange phim thiab kev teeb tsa kom raug.
