Metallic pombi yakasimba, iri nyore kushanda nayo uye haidhure, asi kunyange zvinyoro zvinyoro zvinopisa zvinogona kukurumidza kuidya, kubva mukati zvichienda kunze, zvichidzikamisa hupenyu hwayo zvakanyanya.Nonmetallic pombi, fiberglass uye thermoplastics, haina simba remuviri resimbi pombi, asi ine yakanakisa makemikari kuramba.Plastic lined piping inosanganisa akanakisa ese akajairwa pombi masisitimu mune imwe.
Plastic lined pombi masisitimu inopa kupikisa kwemakemikari emapurasitiki uye simba remukati resimbi, kana alloy metallic pombi masisitimu.Izvi zvakanakira kubata asidhi, corrosives uye zvinhu zvine njodzi.Plastic lined pipe inogona kugadzirwa neine yakasununguka kana yakavharwa mumutsara, zvisinei, yakavharwa mumutsara inoderedza mhedzisiro yemusiyano wekuwedzera coefficient pakati pesimbi uye liner.
Pane zvakawanda zvekunyepa pamusika nezvePTFE mutsetse pombi.Mabatiro anoita vamwe vagadziri vepombi dzepurasitiki iwe unotungamirwa kuti utende kuti ndiyo mhinduro kune ako ese epurasitiki akaiswa pombi zvinodiwa uye ichabata ese masevhisi kubva kune akapfava kusvika kune njodzi.Icho hachisi chokwadi.PTFE lined pombi masisitimu anowanzo kune akati wandei akakosha matambudziko:
1. PTFE lined pipe uye PTFE lined fittings inofanira kubudiswa maererano neASTM tsanangudzo yeplastiki yakavharwa pombi uye mapurasitiki akaiswa fittings, F-1545.PTFE ndiyo yakanyanyisa permeable fluoropolymer yatinosangana nayo uye nekuti inofefeterwa, zvese zvinopinda mu liner zvinoburitswa mumhepo.
2. PTFE ine hurombo hwakanyanya hwemagetsi emhando ipi neipi yefluoropolymer yatinotevedza nayo.Majoini ari muPTFE lined piping system anogara achikanganiswa nekubatana kwakabatana uye kutonhora kuyerera sekutsanangurwa mupombi inopisa nhau link pazasi.Majoini akasimba akakosha pakutendeseka kwepurasitiki ine piping system.Chinhu chimwe chete chakanyanya kuipa pane kuburitsa chigadzirwa chako mumhepo kuchirasira pane vashandi, pasi, kana midziyo kuburikidza nejoini inodonha.
3. PTFE ndiyo inodhura isingadhuri yefluoropolymer resin inoshandiswa mupurasitiki ine pombi ine mitsetse yepurasitiki.Ndiyo 15 kusvika ku20% yemutengo weimwe fluoropolymer resins.Kutengeserana kwacho ndekwekuti iwe unosiya yakanakisa permeation kuramba uye michina zvivakwa kuchengetedza mari.Plastic lined pombi masisitimu anowanzo shandiswa kutakura makemikari ane njodzi uye ane njodzi kuhutano.
