Insimbi engagqwali iwumsebenzi wezempilo owaziwayo ongafakwa emzimbeni womuntu, cishe usetshenziswe kuyo yonke imikhakha ebandakanya impilo yomuntu.Isetshenziswe kabanzi.
I-conduit yensimbi engagqwali iyimpahla yokuvikela imvelo, yanelisa imfuneko enempilo, ingagaywa kabusha ngo-100%, yonge imithombo yamanzi, inciphise izindleko zokuthutha, inciphise ukulahlekelwa ukushisa, igweme ukuhlanza ukuze inikeze inzuzo njengokungcola.Imininingwane imi kanje
1. Insimbi engagqwali inempilo ende yesevisi.Sebenzisa ukuhlaziywa kwesimo esivela phesheya kwensimbi engagqwali, impilo yesevisi ye-stainless steel conduit ingaba neminyaka eyi-100, futhi ibe neminyaka engu-70 okungenani, inqobo nje yokuphila kwesakhiwo.
1.Ukumelana nokugqwala Enye yezinzuzo ezivelele kakhulu zensimbi engagqwali ukumelana kwayo nokugqwala okuhle kakhulu, okuhamba phambili phakathi kwazo zonke izinhlobo zamapayipi.Ngoba insimbi engagqwali ingadlulelwa ngama-oxidants, yakhe ungqimba oluqinile nominyene lwefilimu evikelayo ye-oxide i-Dr2O3 ngaphezulu, ivimbele ngempumelelo ukuqhubeka kwe-oxidation.Futhi enye impahla yamapayipi ensimbi, njengomsele othathiwe, ikhono le-copper passivization lincane kakhulu, okuyisizathu esiyinhloko sokuthi ukumelana nokugqwala kweshubhu lethusi lamapayipi othayela kuncane kakhulu kunokokusebenza kwepayipi lensimbi engagqwali (ishubhu).Insimbi engagqwali ngeke ibe iyunifomu njenge-carbon steel corrosion, sebenzisa ngaphandle kokunamathela okuvikelayo;Ukusetshenziswa kwepayipi lamanzi lensimbi engagqwali, akukho mkhawulo ekubunjweni kwamakhemikhali amanzi, ngoba insimbi engagqwali kuzo zonke izinhlobo zokuqukethwe kwe-oxygen, izinga lokushisa, i-PH nobulukhuni bamanzi kuhle kakhulu ukumelana nokugqwala;Amapayipi amanzi ensimbi engagqwali angakwazi ukumelana namazinga okugeleza aphezulu kakhulu, ngisho noma izinga lokugeleza likhulu kuno-40 m/s, asalondoloza izinga lokugqwala eliphansi kakhulu, elingekho ngaphezu kuka-0.003 mm/ngonyaka, ikakhulukazi elifanele ukuphakelwa kwamanzi asezingeni eliphezulu.Insimbi engagqwali ngokuvamile ayinakho ukugqwala kwendawo, insimbi engagqwali ingamelana nokuqukethwe kwe-chloride kufika ku-200ppm, insimbi engagqwali engu-316 ingamelana nokuqukethwe kwe-chloride kufika ku-1000ppm, lesi siphetho sisekelwe kudatha yokuchayeka futhi siqinisekiswe isipiliyoni.I-coefficient yokunwetshwa okushisayo kweshubhu lensimbi engagqwali neshubhu yethusi cishe izikhathi ezingu-1.5 kuneshubhu lensimbi elivamile.Uma iqhathaniswa neshubhu lensimbi engagqwali, inezici zokukhula kancane kokushisa kanye nokufinyela okubandayo.
I-2.I-conductivity eshisayo yokumelana nokushisa nokugcinwa kokushisa kwensimbi engagqwali yi-1/25 yaleyo yepayipi yethusi kanye ne-1/4 yaleyo yepayipi yensimbi evamile, efanelekile ikakhulukazi ukuthuthwa kwamanzi ashisayo.Insimbi engagqwali 316 kanye nensimbi engagqwali yinsimbi engagqwali esetshenziswa kakhulu embonini yamanzi, engahlangabezana nezimo eziningi zokwelashwa kwamanzi kanye nezimo zokuthutha.
3.Amandla aqinile ensimbi engagqwali izikhathi ezi-2 kunepayipi lensimbi, izikhathi ezi-8 ~ 10 zepayipi lepulasitiki.Ubukhulu bento enqunyiwe yi-conduit ukuthi ngabe inkampani ingakwazi yini ukumelana nokushayisana, iphephile futhi inokwethenjelwa.Ukuphepha nokuthembeka kuyisidingo esibaluleke kakhulu sokuhlinzekwa kwamanzi okwakhiwa.Ngaphansi kwesimo esithola ukuphuma kwamandla angaphandle, amathuba okuthi ukuvuza kwepayipi lensimbi engenasici mancane.Ingcindezi yokusebenza yesistimu yokuhlinzeka ngamanzi aphakeme ngokuvamile inkulu kune-0.6mpa;Izidingo zokucindezela okuphezulu kwepayipi.Ipayipi elincane lensimbi engenasici ngenxa yezakhiwo ezinhle kakhulu zemishini, lingamelana nomfutho wamanzi ophakeme, aze afike ku-10Mpa, afaneleka ngokukhethekile ukunikezwa kwamanzi aphezulu.
