Yini i-ptfe lined hose |I-BESTEFLON

Eminyakeni yamuva nje, i-polytetrafluoroethylene (i-Teflon) iwuhlobo lwemikhiqizo evimbela ukungcoliswa kanye ne-anti fouling yamandla kagesi kanye nemboni ye-petrochemical.Nokho, lezi zinkinga ezilandelayo kufanele inakwe ngokukhethekile laphoI-PTFE ifakwe kulayiniipayipiulayini ushiselwe, ngaphandle kwalokho impilo yesevisi nokuphepha kwepayipi elilayini le-PTFE kuzothinteka.

1. Lapho uhlanza isakhiwo somhlangano, kuvinjelwe ngokuqinile ukulimaza isisekelo sensimbi.Akuvunyelwe ukushaya i-arc esisekelweni sensimbi ngesikhathi sokushisela.

2. Engxenyeni ye-fillet ye-fillet weld, ukuphakama kwe-fillet weld kuyoba kukhulu kuno-5mm, i-angle yokubonisa izoba nkulu noma ilingane no-3mm, futhi i-angle yangaphakathi izoba nkulu noma ilingane no-10mm.

3. Uma ushisela igobolondo lepayipi elilayishiwe le-PTFE, kungcono ukusebenzisa indlela yokushisela ye-double-side side butt welding.Lokhu kudinga izinga lobuchwepheshe labasebenzi bethu, i-weld kufanele ibe isicaba (inguquko ebushelelezi noma ebushelelezi), ingabi nama-pores, i-welding seam kanye nesenzo sokufakwa kwe-slag, futhi ukuphakama kwe-weld akufanele kube ngaphezu kuka-2mm.Ngemuva kwe-welding, i-spatter ebangelwa ukushisela izosuswa ngokuphelele.

4. I-welding eqhubekayo kufanele yamukelwe ekushiseleni ipayipi elinemigqa ye-PTFE, futhi i-weld seam ngeke ibe nemifantu noma i-undercut eqhubekayo.Usesho Oluhlobene:ipayipi le-PTFE eliboshwe, Ipayipi le-PTFE convoluted

I-Polytetrafluoroethylene (PTFE) ingelinye lamagama asetshenziswa kakhulu e-polytetrafluoroethylene.Ipayipi le-PTFE lisetshenziswa kupayipi lensimbi engagqwali, ngakho-ke impilo yesevisi yepayipi yinde kakhulu kunepayipi lerabha noma ipayipi lerabha eligoqwe ngensimbi engagqwali.Inezinzuzo eziningi ngaphezu kwemikhiqizo yenjoloba.

Ikilasi I: I-PTFE inepayipi eliqondile nokufakwa kwamapayipi

Okuvame ukubizwa ngokuthi i-loose liner pipe.Kule nqubo, i-PTFE isetshenziselwa ukuvula ibha.Ilungele umfutho ojwayelekile kanye nepayipi lokuthutha lomfutho omuhle (njengamapayipi amathathu okuhlanza imfucuza, njll.), futhi akufanele isetshenziselwe ipayipi elinomthwalo (njengokungena nokuphuma kwepompo kanye nepayipi elingakhiqiza umfutho ongemuhle. ngokuwa phansi noma ngokupholisa kungazelelwe).

Ukucaciswa kobubanzi: dn25-500mm

Ukushisa kwesevisi: - 40-180oc

Ingcindezi yesevisi: 1.6Mpa

Isigaba II: I-PTFE ipayipi eliqondile eliqinile kanye nokufakwa kwamapayipi

Ngokuvamile kwaziwa njengepayipi eliqinile eligoqwe ngocingo lwensimbi.

Inqubo yokukhiqiza: okokuqala, izingqimba ezimbalwa zefilimu ye-PTFE zilimala esibunjeni, bese kuthi intambo yensimbi (Ø 0.5-1mm) ilinyazwe ngokuvunguza efilimini ye-PTFE, bese kulimala izingqimba ezimbalwa zefilimu elincanyana le-PTFE ngaphandle kwensimbi. ngocingo, futhi ekugcineni isongwe esithandweni ukuze kwenziwe.Udonga lwangaphakathi lwepayipi elilayishiwe le-PTFE elenziwe yile nqubo libushelelezi, futhi udonga lwangaphandle luvunguzekile lukathayela ngenxa yevolumu namandla okunwebeka ocingo lwensimbi.

Isikhala phakathi kodonga lwangaphandle lwepayipi elilayishiwe le-PTFE kanye nodonga lwangaphakathi lwepayipi lensimbi ligcwele inhlaka (ngaphandle komoya oyinsalela).I-resin yokugcwalisa ingahlanganiswa ngokuqinile kumbhobho wensimbi.Ngesikhathi esifanayo, ingasongwa ngokuqinile odongeni olungaphandle lwe-PTFE liner.Ngemva kokuphulukiswa kwe-resin egcwele, i-ripple spiral iyakhiwa evalwe ngodonga lwangaphandle lwe-lining.Lesi sakhiwo sifana nenhlanganisela yamantongomane nebhawodi.Ngakolunye uhlangothi, ingakhawulela ngempumelelo futhi inxephezele ukunwetshwa okushisayo kanye nokufinyela okubandayo kwe-PTFE lining;ngakolunye uhlangothi, ukuqina kocingo lwensimbi kungathuthukisa kakhulu ukumelana nengcindezi engalungile ye-PTFE lining.

Ukucaciswa kobubanzi: dn25-200 mm

Ukushisa okusebenzayo: - 50-180oc

Ingcindezi yokusebenza: 0.5-1.6mpa

Uhlobo lwesithathu: Ipayipi le-PTFE (cindezela) elifakwe ngokuqinile ngepayipi eliqondile

Eyaziwa kakhulu ngokuthi i-push (ukucindezela) ipayipi eliqondile, lisetshenziswa kakhulu emazweni athuthukile ngeminyaka yawo-1990.

Inqubo yokukhiqiza: okokuqala, impushana ye-PTFE engenisiwe isetshenziselwa ukusunduza (ukukhipha) ipayipi, bese iphoqeleka ukuba ingene epayipini lensimbi elingenamthungo (ububanzi bangaphandle bomugqa bukhulu kancane kunobubanzi obungaphakathi bepayipi lensimbi ngo-1.5- 2mm) ukwakha umugqa oqinile ongenamthungo.Ukuze uqede ukucindezela, ufakwa esithandweni futhi ushiswe ku-180oC ukuze uthole ukwelashwa okuqhubekayo kokushisa, ukuze kusetshenziswe ekushiseni okungaphansi kwe-180oC.Ngesikhathi esifanayo, cindezela (cindezela) i-shaft yepayipi

Amandla aqinile ngokusobala angcono kuneshubhu lesilonda.Ipayipi linokumelana okuhle nokucindezela okuhle nokubi.

Umehluko phakathi kolayini lwe-PTFE nolayini lwerabha

Ulwelwesi lwe-tetrafluoroethylene lusetshenziswa ukumelana nokugqwala kwe-fluorine, ukumelana nokushisa okuphezulu, ukumelana ne-asidi eqinile kanye ne-alkali, ukunamathela okuhle kakhulu, impilo ende yesevisi kanye nokumelana nokungena okuqinile.I-tetrafluoroethylene yonke yokufafaza iwumsebenzi wobuchwepheshe obuphezulu, iyiphi inqubo yayo egeleza?1. Ngaphambi kokufafaza, indawo engaphezulu idinga ukuchithwa nesihlabathi, futhi ungqimba lwe-primer ekhethekile lufafazwe.2. Khona-ke i-fluoroplastic powder ishajwa yimishini ye-electrostatic high-voltage, futhi ikhangiswe ngokulinganayo phezu kwendawo yokusebenza ngaphansi kwesenzo sensimu kagesi.3. Ngemuva kokubhaka okuphezulu kokushisa, izinhlayiya ze-clinker zizoncibilika zibe isendlalelo esiqinile sokuzivikela, esihlanganiswe ngokuqinile ebusweni bomsebenzi.Isibonelo, ifilimu yokugqoka engu-1 mm enobukhulu nayo idinga ukufafazwa futhi ibhakwe ngokuphindaphindiwe izikhathi ezingu-5-6.Ngokuvamile, ubukhulu obukhulu bungase bufuthwe bufike ku-2mm.I-PTFE lining ubuchwepheshe obusetshenziswa kabanzi njengamanje.Isebenzisa ngokugcwele ukumelana nokugqwala kwe-fluorine, ukuhlanzeka okuphezulu, ukuhlanzeka, ukunganamatheli, ukungamanzisi, ukuzigcoba, ukumelana nokushisa, ukumelana nokushisa okuphezulu nokuphansi, ukufakwa kwe-insulation, njll. enqubweni yokwakha, i-voltage yayo kanye namanje kulungiswa njalo isimo ekahle ukufeza umphumela enamathela.I-Rubber lining ibizwa nangokuthi i-rubber line.Iwukunamathisela ipuleti lenjoloba elicutshunguliwe endaweni yensimbi ene-adhesive ukuze kuhlukaniswe indawo ebolayo ne-matrix yensimbi ngenjongo yokuvikela.Irabha yemvelo kanye nerabha yokwenziwa isetshenziselwa ulwelwesi.Iningi lenjoloba esetshenziswa emishinini yamakhemikhali irabha yemvelo.Ingxenye eyinhloko yenjoloba yemvelo i-cis polymer ye-isoprene, ehlanjululwa ngokungeza isulfure.Irabha ene-vulcanized inokumelana nokushisa okuthile namandla emishini.Ingahlukaniswa ngenjoloba ethambile, irabha engaqinile kanye nerabha eqinile izinhlobo ezintathu.Irabha eqinile inokumelana nokugqwala okuhle, ukumelana nokuguga namandla okubopha okuqinile ngensimbi.Irabha ethambile inokumelana okuhle nokubandayo, ukumelana nokushisa kanye nokumelana nomthelela, futhi inokuqina okuthile;i-semi hard rubber iphakathi kokubili.Ngaphezu kwama-oxidants aqinile nezinye izinyibilikisi, irabha eqinile ingamelana nokugqwala kwama-acid amaningi angaphili, ama-organic acid, ama-alkali, usawoti kanye notshwala.Ngakho-ke, ulwelwesi lwerabha eqinile lusetshenziswa njengento eyinhloko engeyona eyensimbi elwa nokugqwala.Irabha evuthulukile ingahlukaniswa ibe irabha eshibhile ngaphambili, irabha evamile yamanzi ashisayo ashisayo nerabha yemvelo eshisiwe.Irabha yangaphambi kokuvuthwa isetshenziswa emishinini emikhulu yokukhetha.
