Nrog rau qhov no PTFE xov foob daim kab xev, tsis tas yuav siv cov nplaum nplaum, ntxig yeeb nkab dope thaum koj tab tom kho.PTFE daim kab xev yog qhov zoo rau kev ua kom ceev, huv si, huab cua nruj seals.Nws yog tsim rau cov dej, huab cua los yog roj kab thiab ua hauj lwm ntawm threaded hlau los yog PVC yeeb nkab. Ceev, huv si, huab cua nruj seals; Ua hauj lwm ntawm threaded hlau los yog PVC yeeb nkab; Zoo tagnrho rau cov dej, cua los yog roj kab.
Xov foob daim kab xev (tseem hu ua PTFE daim kab xev los yog cov kav dej kav dej) yog polytetrafluoroethylene (PTFE) zaj duab xis siv rau hauv cov yeeb nkab sib khi.Cov kab xev yog muag txiav rau qhov dav dav thiab qhov txhab ntawm ib lub spool, ua rau nws yooj yim rau cua ncig cov yeeb nkab threads.Nws tseem paub los ntawm cov khoom lag luam-lub npe polymer daim kab xev;Thaum polymer yog qhov tseeb zoo ib yam rau PTFE, Chemours (cov neeg tuav lag luam) xav txog qhov kev siv no tsis raug, tshwj xeeb tshaj yog vim lawv tsis tsim cov khoom siv polymer hauv daim kab xev.Xov foob daim kab xev lubricates tso cai rau lub rooj sib sib zog nqus ntawm cov xov, thiab nws pab tiv thaiv cov xov los ntawm kev ntes thaum raug unscrewed.Cov kab xev kuj ua haujlwm raws li cov khoom siv deformable thiab xov lubricant, pab txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau, cov hlua nws kuj tseem ua haujlwm los ntawm cov txheej txheem deformable.
Hom
Xov foob daim kab xev siv hauv cov kav dej siv feem ntau yog xim dawb, tab sis nws kuj muaj ntau yam xim.Nws yog feem ntau siv los sib piv cov xim coded pipelines (US, Canada, Australia thiab New Zealand: daj rau natural gas, ntsuab rau oxygen, thiab lwm yam). Nyob rau hauv UK, daim kab xev yog siv los ntawm cov xim reels, xws li daj reels rau roj, ntsuab rau potable dej.
* Dawb - siv rau ntawm NPT xov mus txog 3/8 nti * Daj - siv rau ntawm NPT xov 1/2 nti rau 2 nti, feem ntau sau "gas daim kab xev" * Paj yeeb - siv ntawm NPT xov 1/2 nti rau 2 nti, nyab xeeb rau propane thiab lwm yam hydrocarbon fuels * Ntsuab - tsis muaj roj PTFE siv rau ntawm cov pa oxygen thiab qee qhov kev kho mob gasses * Grey - muaj cov npib tsib xee, tiv thaiv kev ntes, tiv thaiv galling thiab tiv thaiv corrosion, siv rau cov kav dej stainless * Copper - muaj tooj liab granules thiab muaj ntawv pov thawj raws li cov xov lubricant tab sis tsis yog sealer
