Daim ntawv thov Scope ntawm octagonal gasket
Octagonal gasket yog ib qho tseem ceeb ntawm cov hlau sealing tivthaiv, uas tuaj yeem tiv taus kev ua haujlwm hnyav vim nws qhov tshwj xeeb octagonal cross-sectional tsim thiab tau siv dav hauv ntau qhov chaw lag luam. Nws lub ntsiab daim ntawv thov Scope muaj xws li:
Kev lag luam roj av thiab roj av: feem ntau yog siv rau kev sib khi cov roj thiab cov kav dej, cov khoom siv hauv lub taub hau, cov ntoo Christmas, siab - siab li qub, thiab flange kev sib txuas, uas tuaj yeem tiv taus qhov kub thiab txias ib puag ncig thiab tsis tshua muaj kev hloov pauv hauv siab thiab kub. cov
Kev lag luam tshuaj thiab petrochemical: haum rau flange sealing ntawm cov hlab ntsha siab, yees, reactors, heat exchangers, thiab siab -pressure pipelines, tshwj xeeb tshaj yog ua tau zoo nyob rau hauv tuav corrosive media. cov
Hauv kev ua haujlwm ntawm lub zog thiab lub zog, nws feem ntau yog siv rau kev sib khi siab - siab cov kav dej, boilers, autoclaves, thiab cov khoom siv hluav taws xob ua kom lub zog ruaj khov ntawm qhov kub siab (txog 1000 degree) thiab siab siab (xws li 15000PSI lossis 150MPa). cov
Cov cuab yeej siv dav dav: siv rau kev sib khi ntau yam siab - kub thiab siab - siab li qub, lub thawv npog, sib koom ua ke, thiab lwm yam, xws li cov hlab ntsha siab, cov kav dej flanges, thiab lwm yam, haum rau kev ua haujlwm nrog qhov kub thiab txias ntawm -196℃txog 1000℃thiab siab ntau ntawm 2.0-150MPa. cov
Octagonal gaskets feem ntau yog ua los ntawm stainless hlau (xws li 304, 316L), carbon steel, los yog hlau alloy, thiab ua raws li cov qauv thoob ntiaj teb xws li API 6A thiab ASME B16.20. Lawv zoo heev corrosion kuj, kub kub thiab siab kub kuj, thiab yoj tsis kam ua rau lawv nyiam sealing tov rau hnyav ua hauj lwm tej yam kev mob.
Feem ntau siv rau cov yeeb nkab flanges, ntau lub tso tsheb hlau luam, cov hlab ntsha siab, siab - nrawm sib koom ua ke, siab - kub thiab siab - siab li qub, thiab npog rau siab - kub thiab siab - siab chav, roj, thiab cov kuab tshuaj. Cov khoom siv Wellhead thiab cov ntsaws ruaj ruaj ntawm cov ntoo Christmas hauv kev lag luam roj av thiab cov nkev
Hlau nplhaib gaskets pib hauv Tebchaws Meskas thiab tau siv thawj zaug hauv kev lag luam boiler hauv xyoo 1920s. Tom qab ntawd, lawv tau siv rau kev sib khi manhole npog thiab lwm qhov rais ntawm siab -siab reactors. Lawv tau txais txiaj ntsig tshwj xeeb hauv kev tsim roj av thiab kev lag luam refining. Raws li qhov ntsuas kub thiab siab ntawm chav fais fab hluav taws xob nce, kev siv cov hlau nplhaib gaskets tau nce zuj zus
