Product Detail

Khoom cim npe

Ib feem uas txuas cov kav dej rau cov kav dej. Txuas rau cov yeeb nkab kawg. Muaj qhov nyob hauv flanges kom cov bolts tuaj yeem hnav kom ob lub flanges nyob ze ua ke. Cov flanges yog kaw nrog gaskets. Flanged yeeb nkab fittings xa mus rau fittings bearing flanges. Nws tuaj yeem raug cam khwb cia, threaded lossis welded. Flange (kev sib koom ua ke) yog tsim los ntawm ib khub ntawm flanges, gasket thiab ib tug xov tooj ntawm bolts thiab ceev. Lub gasket yog muab tso rau ntawm ob lub flange sealing nto. Tom qab zawm cov txiv ntoo, lub siab tshwj xeeb ntawm lub gasket nto yuav deformed thaum nws ncav cuag ib qho nqi, thiab qhov tsis sib xws ntawm lub sealing nto yuav raug sau, kom qhov kev sib txuas yog nruj thiab tsis xau. Qee cov yeeb nkab fittings thiab cov khoom siv muaj lawv tus kheej flanges, kuj yog flange kev twb kev txuas. Kev sib txuas flange yog hom kev sib txuas tseem ceeb hauv kev tsim cov kav dej. Flange kev twb kev txuas yog ib qho yooj yim mus use, muaj peev xwm tiv taus siab loj. Nyob rau hauv kev lag luam pipeline, flange kev twb kev txuas yog dav siv. Hauv tsev, cov yeeb nkab txoj kab uas hla yog me me, thiab nws tsis tshua muaj siab, tsis muaj flange txuas tuaj yeem pom. Yog tias koj nyob hauv chav boiler lossis chaw tsim khoom, muaj flanged kav thiab fittings nyob txhua qhov chaw. Feem ntau hais lus, lub luag haujlwm ntawm flange yog ua kom cov yeeb nkab sib txuas ruaj khov thiab kaw.

Muaj ob lub ntsiab thoob ntiaj teb cov yeeb nkab flange qauv, uas yog German DIN (xws li qub Soviet Union) sawv cev los ntawm European yeeb nkab flange system thiab American ANSI yeeb nkab flange sawv cev los ntawm American yeeb nkab flange system. Tsis tas li ntawd, muaj Japanese JIS raj flanges, tab sis nyob rau hauv cov khoom siv petrochemical feem ntau tsuas yog siv rau pej xeem ua haujlwm, thiab kev cuam tshuam thoob ntiaj teb yog me me.
