Hlau hlua PTFE kav thiab fittings txaus siab rau lub koob npe nrov ntawm "King of Plastics", nrog zoo heev kub thiab corrosion kuj, thiab yog zoo tagnrho rau conveying muaj zog corrosive xov xwm xws li nitric acid, sulfuric acid, hydrofluoric acid, phosgene, chlorine, aqua regia, tov. acids, bromides thiab lwm yam organic solvents.Steel lined PTFE piping thiab fittings uas tuaj yeem ua haujlwm ruaj khov ntawm qhov kub thiab txias (hauv 150 ° C) nyob rau hauv cov xwm txheej tsis zoo rau lub sijhawm ntev tau daws qhov tsis txaus ntawm cov hlau yav dhau los lined PTFE piping thiab fittings uas tsis tuaj yeem tiv taus qhov tsis zoo thiab siv dav hauv ntau distillation thiab lwm yam kub thiab siab tsis zoo siab tshuab.
Lub steel lined teflon laub-siab yeeb nkab yog cov neeg kho tshuab ua haujlwm nkaus xwb, piv nrog rau lwm cov hlau lined teflon yeeb nkab ua tshuab, steel lined teflon yeeb nkab tsim muaj: siab ceev, du nto, uniform thickness thiab lwm yam ntxwv.Qhov "siab ceev" tiv thaiv qhov nruab nrab los ntawm kev nkag mus thiab tsis yooj yim deformed hauv kev siv;lub "smooth nto" ua rau nruab nrab ndlwg tsis kam me me thiab zoo tiv thaiv cov nplaum;lub "uniform thickness" ua rau cov hlau hlua PTFE yeeb nkab muaj lub zog siab thiab zoo sealing kev ua tau zoo ntawm flange.Nws yog tsim rau ntau yam acids, alkalis, muaj zog oxidants, aqua regia thiab lwm yam muaj zog corrosive media.
Piv nrog rau lwm cov steel lined Teflon kav, steel lined Teflon kav muaj cov yam ntxwv nram qab no: siab ceev, du nto, uniform thickness, thiab lwm yam "siab ceev" tiv thaiv qhov nruab nrab ntawm kev nkag mus thiab tsis yooj yim deformed hauv kev siv;lub "smooth nto" ua rau nruab nrab ndlwg tsis kam me me thiab zoo tiv thaiv cov nplaum;lub "uniform thickness" ua rau cov hlau hlua PTFE yeeb nkab muaj lub zog siab thiab zoo sealing kev ua tau zoo ntawm flange.Nws yog tsim rau ntau yam acids, alkalis, muaj zog oxidants, aqua regia thiab lwm yam muaj zog corrosive media.
