Imishini yokwenza imithi kanye nezinhlelo zamapayipi zithembele kakhulu ensimbi engagqwali, ukuze kuhlinzekwe ukwakhiwa okungasasebenzi, ukumelana nokugqwala okudingekayo ekukhiqizeni nasekushiseni.ukuvala inzalo.Kodwa-ke, ama-thermoplastic ayatholakala anganikeza izimfanelo ezithuthukisiwe noma izindleko eziphansi.Amapulasitiki angabizi kakhulu njenge-polypropylene (PP) ne-polyvinyl chloride (PVC) angase amukeleke kumasistimu angakhokhelwa.Okunye, okufana ne-polyvinylidene fluoride (PVDF) enikeza ukumelana nokushisa okukhulu, ingase ifanelekele amanzi ayisinxephezelo, nakuba idinga ukusekelwa okuqhubekayo ekusetshenzisweni okushisayo.Izindleko zohlelo lwe-PVDF zingaba cishe ngamaphesenti angu-10-15 kunezindleko zesistimu yensimbi engagqwali uma izici ezifana nokudlula, ukuhlolwa kwe-radiographic ye-boroscope, njll., zifakiwe.Izindlela ezintsha zokuhlanganisa amashubhu e-PVDF zishiya ukushisela kubushelelezi kakhulu kunalokho okunokwenzeka ngensimbi engagqwali.Emazingeni okushisa aphezulu, nokho, ukwanda okushisayo kwepulasitiki kuba yinto ekhathazayo enkulu.
Ukukhethwa kwezinto kufanele kuhambisane (konke okungu-316L noma konke okungu-304L njll.) kuwo wonke amasistimu okusabalalisa, ukugcinwa, nokucubungula uma ukudlula okuvamile kuhlelwa.
Ngamanzi ayisinxephezelo, ukusetshenziswa kwensimbi engu-316L kukhethwa.I-Insulation ye-amapayipi angagqwalikufanele ingabi nama-chloride, nama-hangers ahlinzekwe ngezihlukanisi ukuvimbela ukugqwala kwe-galvanic.
I-304L kanye ne-316L yensimbi engagqwali kube yinto ethandwayo embonini emathangini ukuze kugcinwe amanzi ayisinxephezelo.Okubalulekile kwejakhethi okuthintana negobolondo kufanele kuhambisane, ukugwema ukuncipha kwe-chromium ezindaweni ezithinteke ngokushisela.Ukugcinwa kwamanzi okungaphoqelekile kungase kungadingi izinga elifanayo lokumelana nokugqwala noma ukusetshenziswa kwama-alloys e-carbon nickel-chromium ephansi kanye nokuqedwa okukhethekile, kuye ngomnikazi.'s imininingwane yamanzi.
