1) Ukumelana Nokugqwala kanye Nokuphila Isikhathi Eside Senkonzo

Amapayipi e-FRP anokumelana okuhle kakhulu nokugqwala, amelana nokugqwala okuvela kuma-asidi, ama-alkali, usawoti, amanzi olwandle, amanzi angcolile anamafutha, inhlabathi egqwalisayo, kanye namanzi angaphansi komhlaba—okungukuthi, izinto eziningi zamakhemikhali. Aphinde abonise ukumelana okuhle nama-oxide aqinile nama-halogen. Ngakho-ke, isikhathi sokuphila sala mapayipi sandiswa kakhulu, ngokuvamile sidlula iminyaka engama-30. Ukulingisa kwelebhu kubonisa ukuthiAmapayipi e-FRPingaba nokuphila kwenkonzo okungaphezu kweminyaka engama-50. Ngokuphambene nalokho, amapayipi ensimbi ezindaweni eziphansi, ezine-alkali kasawoti, noma ezinye izindawo ezigqwala kakhulu adinga ukulungiswa ngemva kweminyaka emi-3-5 kuphela, kanye nokuphila kwenkonzo okucishe kube yiminyaka eyi-15-20 kuphela, kanye nezindleko zokulungisa eziphakeme ezigabeni zakamuva zokusetshenziswa. Okuhlangenwe nakho kwasekhaya nakwamanye amazwe kuye kwafakazela ukuthi amapayipi e-FRP agcina u-85% wamandla awo ngemva kweminyaka eyi-15 kanye no-75% ngemva kweminyaka engama-25, kanye nezindleko zokulungisa eziphansi. Womabili la manani adlula izinga lokugcina amandla elincane elidingekayo emikhiqizweni ye-FRP esetshenziswa embonini yamakhemikhali ngemva konyaka owodwa wokusetshenziswa. Ukuphila kwenkonzo kwamapayipi e-FRP, okuyinkinga enkulu, kuye kwafakazelwa idatha yokuhlola evela kuzinhlelo zokusebenza zangempela. 1) Izici Ezinhle Ze-Hydraulic: Amapayipi e-FRP (ipulasitiki eqiniswe nge-fiberglass) afakwe e-US ngawo-1960 abelokhu esetshenziswa iminyaka engaphezu kwengu-40 futhi asasebenza ngokujwayelekile.

2) Izici Ezinhle Ze-Hydraulic

Izindonga zangaphakathi ezibushelelezi, ukungqubuzana okuphansi kwamanzi, ukonga amandla, kanye nokumelana nokukhula nokugqwala. Amapayipi ensimbi anezindonga zangaphakathi eziqinile, okuholela ekungqubuzaneni okuphezulu okwanda ngokushesha ngokugqwala, okuholela ekulahlekelweni okuqhubekayo kokumelana. Indawo elukhuni iphinde ihlinzeke ngezimo zokubekwa kwesikali. Amapayipi e-FRP, nokho, anokungqubuzana okungu-0.0053, okungu-2.65% wamapayipi ensimbi angenamthungo, kanti amapayipi epulasitiki ahlanganisiwe aqinisiwe anokungqubuzana okungu-0.001 kuphela, okungu-0.5% wamapayipi ensimbi angenamthungo. Ngakho-ke, ngenxa yokuthi udonga lwangaphakathi luhlala lubushelelezi kuyo yonke impilo yalo, i-coefficient yokumelana ephansi inciphisa kakhulu ukulahlekelwa yingcindezi epayipini, isindisa amandla, ikhulisa umthamo wokuthutha, futhi iletha izinzuzo ezinkulu zomnotho. Indawo ebushelelezi iphinde ivimbele ukufakwa kwezinto ezingcolisayo ezifana namagciwane, isikali, kanye ne-wax, ivimbele ukungcola kwendawo ethuthwayo.

3) Okuhle Kokulwa Nokuguga, Ukumelana Nokushisa, kanye Nokumelana Nokuqandisa

Amapayipi e-fiberglass angasetshenziswa isikhathi eside ngaphakathi kwebanga lokushisa eliphakathi kuka--40 kuya ku-80℃. Ama-resin amelana nokushisa okuphezulu anezindlela ezikhethekile angasebenza ngokujwayelekile ngisho nasemazingeni okushisa angaphezu kuka-200℃. Kumapayipi asetshenziswa ngaphandle isikhathi eside, ama-absorber e-ultraviolet ayengezwa endaweni engaphandle ukuze kuqedwe imisebe ye-ultraviolet futhi kuncishiswe ukuguga.

4) Ukushisa okuphansi, ukuvikela okuhle kanye nezakhiwo zokuvikela kagesi

Ukushisa kwezinto ezisetshenziswa kakhulu zamapayipi kuboniswe kuThebula 1. Ukushisa kwamapayipi e-fiberglass kungu-0.4 W/m·K, cishe okungu-8‰ kwensimbi, okuholela ekusebenzeni kahle kokushisa. I-Fiberglass nezinye izinto ezingezona ezensimbi azikwazi ukufudumala, zinokumelana kokushisa okungu-10¹² kuya ku-10¹⁵ Ω·cm, okuhlinzeka ngokushisa okuhle kakhulu kukagesi, okwenza kube kuhle ukusetshenziswa ezindaweni ezinezintambo zokudlulisa amandla amakhulu kanye nezokuxhumana kanye nezindawo ezivame ukushaywa umbani.

5) Ilula, amandla aphezulu, kanye nokumelana okuhle nokukhathala

Ubuningi beipulasitiki eqiniswe nge-fiberglass (i-FRP)iphakathi kuka-1.6 no-2.0 g/cm³, okuphindwe ka-1-2 kuphela kunensimbi evamile kanye ne-aluminium engaba yi-1/3. Ngenxa yokuthi imicu eqhubekayo ku-FRP inamandla aphezulu okudonseka kanye ne-elastic modulus, amandla ayo okusebenza angafinyelela noma adlule awensimbi evamile yekhabhoni, futhi amandla ayo athile aphindwe kane kunawensimbi. Ithebula 2 libonisa ukuqhathaniswa kobuningi, amandla okudonseka, kanye namandla athile e-FRP nezinsimbi eziningana. Izinto ze-FRP zinokumelana okuhle kokukhathala. Ukwehluleka kokukhathala ezintweni zensimbi kuvela ngokuzumayo kusuka ngaphakathi kuya ngaphandle, ngokuvamile ngaphandle kwesixwayiso sangaphambilini; noma kunjalo, ezintweni ezihlanganisiwe eziqiniswe ngefayibha, ukuxhumana phakathi kwemicu kanye ne-matrix kungavimbela ukusabalala kwemifantu, futhi ukwehluleka kokukhathala kuhlala kuqala endaweni ebuthakathaka kakhulu ezintweni. Amapayipi e-FRP angalungiswa ukuthi abe namandla ahlukene okuzungeza kanye nokuzungeza ngokushintsha i-fiber layup ukuze ifane nesimo sokucindezeleka, kuye ngamandla azungezayo kanye nawa-axial.

6) Ukumelana okuhle nokuguguleka

Ngokusho kokuhlolwa okufanele, ngaphansi kwezimo ezifanayo nangemva kwemijikelezo yomthwalo engu-250,000, ukuguguleka kwamapayipi ensimbi kwakucishe kube ngu-8.4 mm, amapayipi esimende e-asbestos cishe angu-5.5 mm, amapayipi esimende cishe angu-2.6 mm (anesakhiwo sobuso obufanayo ne-PCCP), amapayipi obumba cishe angu-2.2 mm, amapayipi e-polyethylene aphezulu cishe angu-0.9 mm, kuyilapho amapayipi e-fiberglass aguguleka kuphela aze afike ku-0.3 mm. Ukuguguleka kobuso kwamapayipi e-fiberglass kuncane kakhulu, kungu-0.3 mm kuphela ngaphansi kwemithwalo esindayo. Ngaphansi kwengcindezi evamile, ukuguguleka kokuxhumana ngaphakathi kolwelwesi lwepayipi le-fiberglass akunamsebenzi. Lokhu kungenxa yokuthi ulwelwesi lwangaphakathi lwepayipi le-fiberglass lwakhiwe nge-resin enokuqukethwe okuphezulu kanye nolwelwesi lwe-fiber lwengilazi oluqoshiwe, futhi ungqimba lwe-resin ebusweni bangaphakathi luvikela ngempumelelo ekuvezweni kwefayibha.

7) Ukuhleleka okuhle

I-Fiberglass iyinto ehlanganisiwe enezinhlobo zezinto zokwakha, izilinganiso, kanye nokuhlelwa okungashintshwa ukuze kuvumelane nezimo zokusebenza ezahlukahlukene. Amapayipi e-Fiberglass angaklanywa futhi akhiqizwe ukuze ahlangabezane nezidingo zomsebenzisi ezahlukahlukene, njengezinga lokushisa elihlukile, amazinga okugeleza, ingcindezi, ukujula kokungcwaba, kanye nezimo zomthwalo, okuholela kumapayipi anokumelana okuhlukile kwezinga lokushisa, izilinganiso zokucindezela, kanye namazinga okuqina.Amapayipi e-fiberglassUkusebenzisa ama-resin aqine kakhulu akhiwe ngokukhethekile kungasebenza ngokujwayelekile emazingeni okushisa angaphezu kuka-200℃. Ukufakwa kwamapayipi e-Fiberglass kulula ukuwakhiqiza. Ama-Flanges, ama-elbow, ama-tee, ama-reducer, njll., angenziwa ngokungahleliwe. Isibonelo, ama-flanges angaxhunywa kunoma yiliphi i-flange yensimbi enomfutho ofanayo kanye nobubanzi bepayipi obuhambisana nezindinganiso zikazwelonke. Ama-elbow angenziwa nganoma iyiphi i-engeli ngokuya ngezidingo zendawo yokwakha. Kwezinye izinto zamapayipi, ama-elbow, ama-tee, nezinye izinto zokufakwa kunzima ukuzenza ngaphandle kwezingxenye ezijwayelekile zezincazelo ezichaziwe.

8) Izindleko eziphansi zokwakha nokulungisa

Amapayipi e-fiberglass alula, aqinile kakhulu, athambile kalula, kulula ukuwathutha, futhi alula ukuwafaka, awadingi ilangabi elivulekile, okuqinisekisa ukwakhiwa okuphephile. Ubude bepayipi elilodwa elide bunciphisa inani lamajoyinti kuphrojekthi futhi buqeda isidingo sokuvimbela ukugqwala, ukulwa nokungcola, ukufudumala, kanye nezinyathelo zokulondoloza ukushisa, okuholela ezindlekweni zokwakha nezokulungisa eziphansi. Ukuvikelwa kwe-cathodic akudingeki kumapayipi agqitshwe, okungonga ngaphezu kuka-70% wezindleko zokulungisa zobunjiniyela.
