Txuj: ASME B16.20
Khoom siv: Carbon Steel, Stainless hlau 304, Stainless hlau 304L, Stainless hlau 316, Stainless hlau 316L,
Siv: Rau yeeb nkab flange ASME B16.5, ASME B16.47 Series A, ASME B16.47 Series B thiab lwm yam
metallic gaskets rau cov yeeb nkab flanges R Nplhaib -kos octagonal gasket kev taw qhia:
Octagonal gasket yog cov khoom siv hlau uas muaj tus ntoo khaub lig-cov duab ntawm octagon ua los ntawm cov khoom siv hlau los ntawm kev sib tsoo, kev kho cua sov, thiab kev siv tshuab. Nws muaj ib tug radial nws tus kheej zawm sealing nyhuv thiab yog ib hom qauv R- hom hlau nplhaib gasket. Nws txoj hauv kev ua haujlwm yog tias lub cushion ncoo hu rau sab hauv thiab sab nrauv (tsuas yog sab nrauv) ntawm flange ntaiv zawj, thiab yog compressed los tsim cov nyhuv sealing.
metallic gaskets rau cov yeeb nkab flanges R Ring -joint octagonal gasket qhov ntev thiab kam rau ua:
Puab: Octagonal, Elliptical
Scope ntawm daim ntawv thov: Kub: -200-800℃Siab: 2.0-42 megapascals
Haum rau flange sealing ntawm qhov kub thiab txias thiab siab siab pipelines.
Lub octagonal hlau nplhaib gasket yog ntsia rau hauv tus ntaiv zoo li zawj ntawm flange nto. Thaum lub ntsia liaj qhov rooj txuas yog nruj, nws yog compressed axially thiab nias rau sab sauv thiab sab ntaiv zoo li tus grooves, ua rau cov yas deformation thiab tsim ib tug annular sealing band, tsim thawj lub foob. Tom qab lub siab nce, lub nplhaib gasket nthuav tawm radially nyob rau hauv qhov kev txiav txim ntawm qhov nruab nrab siab. Lub gasket yog nruj nreem txuas rau qhov inclined nto ntawm lub trapezoidal groove, tsim kom muaj tus kheej zawm nyhuv. Txawm li cas los xij, qhov nce hauv nruab nrab siab kuj tuaj yeem ua rau deformation ntawm flange thiab txuas bolts, uas ua rau muaj kev sib cais ntawm qhov chaw sib khi thiab cov txheeb ze txo qis hauv qhov sib piv ntawm lub gasket. Yog li ntawd, lub gasket tuaj yeem suav hais tias yog ib qho kev sib khi ntawm tus kheej.
Lub octagonal hlau nplhaib gasket phim lub flange zawj feem ntau los ntawm kev sib cuag saum npoo. Txawm hais tias nws tsis yooj yim rau kev ua tiav nruj nrog lub flange zawj piv rau lub nplhaib elliptical gasket, nws tuaj yeem rov qab siv tau thiab yooj yim rau kev ua haujlwm vim nws txoj kab ncaj nraim -section. Nyob rau tib lub sijhawm, lub hardness ntawm octagonal hlau nplhaib gasket khoom yuav tsum yog 15-20HB qis dua li ntawm flange nto.
