Okokuqala, ikhasimende lidinga ukucacisa imininingwane namamodeli we-izindololwanebadinga ukuthenga, okungukuthi, ububanzi bendololwane, Kufanele bacabangele ukuthi bangakhetha indololwane elinganayo noma banciphise indololwane, futhi baqinisekise izindinganiso, amazinga okucindezela, noma ukushuba kodonga lwendololwane.Okwesibili, impahla yezindololwane kufanele icatshangelwe.Okwesibili, kufanele kubhekwane nodaba lokuvimbela ukugqwala, nokuthi izindololwane zidinga ukupendwa noma zifakwe isihlabathi.
1. Kungani unaka izinto zendololwane?
Ngezinhloso ezahlukahlukene, kuyadingeka ukusebenzisa izindololwane ezihambisanayo zezinto ezahlukahlukene ukufanisa.Izinto ezivamile zingahlukaniswa zibeinsimbi engagqwali izindololwanefuthicarbon steel izindololwane.Ukwakheka kwamakhemikhali okuqukethwe ezindololwaneni zensimbi engagqwali kuzovimbela indololwane ukuthi ingagqwali nokugqwala isikhathi eside.Isizathu esiyinhloko somehluko wayo ezindololwaneni ze-carbon steel umehluko wezinto ezibonakalayo.
Indololwane yensimbi engagqwali yakhiwa ngokugxiviza umumo oyindilinga kusuka eshidini lento efanayo, ihlanganise amahhafu amabili ndawonye bese ewashisela ndawonye.Ngemuva kokuthi iphushelwe ngaphakathi, iphinde ibunjwe kabusha ngaphansi kokushisisa ukuze kuqinisekiswe ukuthi ububanzi bangaphandle nokuqina kodonga lwendololwane kuhlangabezana nezidingo.Bese, ukuchama okudutshulwa kukhishwa ukuze kukhishwe isikhumba se-oxide ekufakweni kwendololwane yangaphakathi nendawo yangaphandle yekhanda eligobayo, iziphetho zombili zitshekele ukuze kushiselwe kalula.
2. Kungani unaka ubukhulu bendololwane?
Indololwane evamile iwusayizi ophindwe kakodwa nohhafu, imelwe ngu-R=1.5D.Kodwa-ke, kuyo yonke imakethe yokufaka amapayipi, isikhunta esiningi sokukhiqiza singu-1.25D, okuyigebe elingu-0.25D.Izinto ezingasetshenzisiwe ezisetshenziselwa ukusunduza izindololwane, okungukuthi, amapayipi, zingasindisa kakhulu, okuholela kumehluko omkhulu wesisindo kanye nomehluko wamanani.Lokhu kwaziwa njengezindololwane ezingajwayelekile, ezimfishane kakhulu kunezindololwane ezijwayelekile.Amamodeli angalungile ezindololwane nawo angabangela izinkinga zokungafani ngesikhathi sokusetshenziswa, okuholela ekungasebenzini kwemishini.
3. Kungani kudingeka sinqume ukuthi ziyadingeka yini izindololwane ezilwa nokugqwala?
Indololwane ye-Anticorrosive ibhekisela endololwaneni eye yacutshungulwa futhi yaphathwa ngobuchwepheshe bokuqeda ukugqwala, okungavimbela ngokuphumelelayo noma ukunciphisa ukuvela kokusabela kwamakhemikhali ngesikhathi sokuthutha nokusetshenziswa, okuholela ekugqwaleni kwendololwane.Izindlela ezijwayelekile zihlanganisa ukusebenzisa izindwangu zokulwa nokugqwala ezingenabuthi nezingenaphunga zokwelashwa, nokusebenzisa impushana ye-epoxy ebusweni bezindololwane kusetshenziswa ukufutha nge-electrostatic.Izindololwane ze-Anticorrosive azigcini nje ngokumelana nokugqwala, kodwa futhi zimelana nokugoba, izinga lokushisa eliphezulu, umthelela, ukoma ngokushesha, ukumelana ne-alkali, ukunamathela okuhle, ukumelana ne-asidi, ukumelana nosawoti, nokuthamba okuhle.Zifanele imikhakha ehlukahlukene efana negesi yemvelo, ukukhucululwa kwendle, uphethiloli, namanzi ompompi.Izindololwane ezivimbela ukubola ngokuvamile zisetshenziswa ezikhathini ezithile ezikhethekile.
4. Kungani unake ukushuba odongeni izindololwane?
Uma sithatha indololwane ekukhiqizweni nasekusebenzeni kwegesi yemvelo njengesibonelo, indololwane yokuqoqwa kwegesi yemvelo kanye nepayipi lokuthutha ijwayele ukuncipha ngokushesha ngaphansi kokuguguleka kokugqwala nokuguguleka okuhlangene, okuthinta ukuphepha kokusebenza kwamapayipi.Ngakho-ke, kuyadingeka ukukala ukushuba kodonga endololwaneni yepayipi.Ukusetshenziswa kobuchwepheshe bokulinganisa ukushuba kwe-ultrasonic ekuhlolweni kwesampula kokuqina kodonga engxenyeni yendololwane yokuqoqwa kwegesi yemvelo kanye nenethiwekhi yamapayipi okuthutha kuyasetshenziswa.
