Chii chinonzi ptfe lined hose |BESTEFLON

Mumakore achangopfuura, polytetrafluoroethylene (Teflon) imhando yeanti fouling uye anti fouling zvigadzirwa zvemagetsi emagetsi uye petrochemical indasitiri.Zvisinei, matambudziko anotevera anofanira kubhadharwa zvakanyanya apoPTFE ine mutsarahosemutsara wakaiswa welded, zvikasadaro hupenyu hwesevhisi uye kuchengetedzeka kwePTFE pombi yakamisikidzwa ichakanganiswa.

1. Paunenge uchichenesa chigadziro chegungano, zvinorambidzwa zvachose kukuvadza nheyo yesimbi.Zvinorambidzwa kurova arc pane base simbi panguva welding.

2. Muchikamu che fillet ye fillet weld, urefu hwe fillet weld huchave hwakakura kudarika 5mm, angle yekufungidzira ichave yakakura kudarika kana yakaenzana ne3mm, uye kona yemukati ichave yakakura kudarika kana yakaenzana ne10mm.

3. Paunenge uchiputira goko rePTFE lined pombi, zviri nani kutora nzira yewelding yekaviri-sided butt welding.Izvi zvinoda tekinoroji yevashandi vedu, iyo weld inofanirwa kuve yakati sandara (yakatsetseka kana yakatsetseka shanduko), isina pores, welding musono uye slag inclusion chiitiko, uye kureba kweweld hakufanirwe kunge kwakakura kupfuura 2mm.Mushure mekuputika, spatter inokonzerwa nekuputika ichabviswa zvachose.

4. Kuenderera mberi kusungirirwa kunofanira kugamuchirwa mukuputika kwePTFE lined pipe, uye weld seam haifaniri kuva nekutsemuka kana kuenderera mberi kwepasi.Tsvakiridzo Dzinoenderana:yakarukwa PTFE hose, PTFE hosi yakavharwa

Polytetrafluoroethylene (PTFE) nderimwe remazita anowanzoshandiswa epolytetrafluoroethylene.PTFE hose inoshandiswa mupombi yesimbi isina tsvina, saka hupenyu hwesevhisi hwepaipi hwakareba kupfuura hosi yerabha kana hosi yerabha yakaputirwa nesimbi isina tsvina.Iine zvakawanda zvakanakira pamusoro pezvigadzirwa zverubha.

Kirasi I: PTFE yakamisikidzwa pombi uye pombi fittings

Inowanzozivikanwa se loose liner pipe.Mukuita uku, PTFE inoshandiswa kushandura bar.Yakakodzera kudzvanywa yakajairika uye yakanaka yekumanikidza pombi yekufambisa (senge pombi nhatu dzekurasa tsvina, nezvimwewo), uye haifanirwe kushandiswa papombi ine mutoro (sekupinza nekubuda kwepombi uye pombi inogona kuburitsa kusagadzikana kwakashata. nekudonha kana kutonhora kamwe kamwe).

Dhiyamita yakatarwa: dn25-500mm

Kupisa kwebasa: - 40-180oc

Service pressure: 1.6Mpa

Kirasi II: PTFE yakasimba yakamisikidzwa pombi yakatwasuka uye pombi fittings

Inowanzozivikanwa sepombi yakamanikana yakaputirwa nesimbi waya.

Maitiro ekugadzira: chekutanga, akati wandei e PTFE firimu anokuvadzwa paforoma, ipapo waya yesimbi (Ø 0.5-1mm) inokuvadzwa nemhepo paPTFE firimu, uyezve akati wandei ePTFE firimu nhete inokuvadzwa kunze kwesimbi. waya, uye pakupedzisira yakaputirwa muchoto kuti igadzire.Rusvingo rwemukati rwePTFE mutsara wepombi yakagadzirwa neiyi nzira yakatsetseka, uye madziro ekunze ane spiral corrugated nekuda kwehuwandu uye elastic simba resimbi waya.

Nzvimbo iri pakati pekunze kwemadziro ePTFE yakamisikidzwa pombi uye mukati memadziro esimbi pombi yakazadzwa neresin (isina mhepo yakasara).Iyo resin yekuzadza inogona kusungirirwa zvakasimba kune pombi yesimbi.Panguva imwecheteyo, inogona kuvharirwa zvakasimba pamadziro ekunze e spiral PTFE liner.Mushure mekuporeswa kweresin yakazadzwa, iyo spiral ripple inoumbwa iyo yakavharwa nekunze kwemadziro ripple re lining.Ichi chimiro chakafanana nekubatanidzwa kwe nut uye bolt.Kune rimwe divi, inokwanisa kudzikamisa uye kubhadharira kuwedzera kwekupisa uye kutonhora kuderera kwePTFE lining;kune rumwe rutivi, kuoma kwetambo yesimbi kunogona kuvandudza zvakanyanya kusagadzikana kwekudzivirira kwePTFE lining.

Dhiyamita yakatarwa: dn25-200 mm

Kushanda tembiricha: - 50-180oc

Kushanda kudzvinyirira: 0.5-1.6mpa

Rudzi rwechitatu: PTFE kusunda (kusvina) pombi yakasungirirwa nepombi yakatwasuka

Inonyanya kuzivikanwa sekuti push (squeeze) yakamisikidzwa pombi yakatwasuka, inoshandiswa zvakanyanya munyika dzakabudirira muma1990.

Maitiro ekugadzira: chekutanga, iyo inotengeswa kunze kwenyika PTFE poda inoshandiswa kusundira (extrude) pombi, uye yobva yamanikidzwa kupinda mupombi yesimbi isina musono (iyo dhayamita yekunze ye liner yakakura zvishoma kupfuura dhayamita yemukati yesimbi pombi ne1.5- 2mm) kugadzira tambo isina musono yakasimba.Kuti ubvise kudzvinyirirwa, inoiswa muchoto uye inopisa kusvika 180oC yekugara kwekushisa kwekushisa, kuitira kuti inogona kushandiswa mukupisa pasi pe180oC.Panguva imwecheteyo, shandisa (kusvina) shaft yepombi

Iko kusimba kusimba kuri pachena kuri nani pane iyo yechubhu yeronda.Iyo pombi ine kupikisa kwakanaka kune yakanaka uye yakaipa kumanikidza.

Musiyano pakati pePTFE lining uye rubber lining

Lining tetrafluoroethylene inoshandiswa kushandiswa kwefluorine's corrosion resistance, high tembiricha kuramba, asidhi yakasimba uye alkali kuramba, kunamira zvakanaka, hupenyu hurefu hwebasa uye kuramba kwakasimba kwekupinda.Iyo yose yekupfapfaidza tetrafluoroethylene ibasa repamusoro-soro, ndeipi maitiro ayo anoyerera?1. Usati wapfapfaidza, nzvimbo yacho inoda kuputirwa nejecha uye kuomeswa, uye chidimbu cheprimer yakakosha inopfapfaidzwa.2. Zvadaro fluoroplastic powder inopomerwa ne-high-voltage electrostatic equipment, uye yakaenzana adsorbed pamusoro pebasa rekushanda pasi pechiito chemunda wemagetsi.3. Mushure mekupisa kwepamusoro kubheka, zvimedu zve clinker zvichanyunguduka kuva dense kudzivirira layer, iyo yakanyatsobatanidzwa pamusoro pebasa rekushanda.Semuenzaniso, 1 mm gobvu yekuputira firimu inodawo kupfapfaidzwa uye kubikwa kakawanda kwe5-6 nguva.Kazhinji, ukobvu hwepamusoro hunogona kupfapfaidzwa kusvika 2mm.PTFE lining tekinoroji inoshandiswa zvakanyanya parizvino.Inoshandisa zvizere fluorine's corrosion resistance, kuchena kwepamusoro, kuchena, kusanamira, kusanyorova, kuzvizora mafuta, kupfeka kuramba, yakakwirira uye yakaderera tembiricha kuramba, insulation, nezvimwewo mukuvaka, voltage yaro uye yazvino zvinogara zvichigadziriswa kune iyo chimiro chakanaka kuti uwane iyo coating effect.Rubber lining inonziwo rubber lining.Ndekunamira ndiro yakagadziridzwa yerabha pamusoro pesimbi nenamira kuti iparadzanise svikiro rinopisa kubva kune simbi matrix nechinangwa chekudzivirira.Natural rubber uye synthetic rubber inoshandiswa kugadzira.Yakawanda yerabha inoshandiswa mumakemikari emidziyo lining ndeye yakasikwa rabha.Chinhu chikuru cherabha yechisikigo ndeye cis polymer ye isoprene, iyo inosvibiswa nekuwedzera sarufa.Iyo vulcanized rabha ine kumwe kupisa kwekudzivirira uye simba remagetsi.Inogona kukamurwa kuita rabha yakapfava, semi-yakaoma rabha uye yakaoma rabha marudzi matatu.Hard rabha ine yakanaka corrosion resistance, kuchembera kuramba uye yakasimba bonding simba nesimbi.Rabha yakapfava ine yakanaka kutonhora kupikisa, kupisa kupisa uye kukanganisa kupikisa, uye ine imwe elasticity;semi hard rubber iri pakati pemaviri.Kuwedzera kune yakasimba oxidants uye zvimwe zvinonyungudutsa, hard rabha inogona kuramba kukora kweakawanda inorganic acids, organic acids, alkalis, munyu uye doro.Naizvozvo, iyo yakaoma rabha lining inoshandiswa seyakanyanya isiri-metallic anti-corrosion zvinhu.Vulcanized rabha inogona kupatsanurwa kuita pre vulcanized rabha, yakajairwa mvura inopisa inopisa rabha uye yakasikwa vulcanized rabha.Pre vulcanized rubber inoshandiswa mumidziyo mikuru yekunhonga.
