Ipuleti eliyimpumputhe le-Flange libizwa nangokuthi i-blind flange, igama langempela eliyipuleti eliyimpumputhe. Kuyindlela yokuxhumana ye-flange. Omunye wemisebenzi yawo ukuvimba ukuphela kwepayipi, kanti omunye uwukwenza kube lula ukukhishwa kwemfucumfucu epayipini ngesikhathi sokulungiswa. Ngokuqondene nomphumela wokuvala uphawu, unomphumela ofanayo nekhanda ne-tube cap. Kodwa ayikho indlela yokuhlukanisa ikhanda, futhi ipuleti eliyimpumputhe le-flange lihlanganiswe nama-bolts, i-disassembly elula kakhulu. Ikhwalithi yepuleti eliyimpumputhe le-Flange yinsimbi ye-carbon, i-alloy steel, insimbi engagqwali, ipulasitiki nokunye. Ipuleti eliyi-flange blind lisetshenziselwa ukuvala ukuphela kwepayipi, okuhlanganisa ipuleti eliyimpumputhe elishiselwe kanye nesembozo se-flange (ikhava ye-flange ibhowudi). Isembozo se-flange yipuleti eliyimpumputhe le-flange, futhi ipuleti eliyimpumputhe le-flange alilona nje kuphela uhlobo lwekhava ye-flange, kodwa futhi ipuleti eliyimpumputhe elishiselwe, ipuleti eliyimpumputhe elibambayo njalonjalo.

Ekwakhiweni kwe-flange blind flange, kunamaphuzu amaningana ayisihluthulelo adinga ukunakwa ekwakhiweni: ukwakheka okunengqondo kwe-flange, okungukuthi, ukwakheka okufanele kwe-alloy flange cone neck kanye ne-flange ring ratio, yenza i-torque ye-flange ibe mncane. ngangokunokwenzeka, ukuze unciphise inkomba yokucindezeleka ye-flange; Ngokwesimo sokusebenza, ukukhethwa okufanele kwezinto ze-gasket kanye nomklamo onengqondo wobubanzi be-gasket, ukunciphisa ukulayisha kuqala kwebhawodi namandla okusebenza; Ukukhetha okunengqondo kwempahla yebholidi, ububanzi bebhawodi kanye nenombolo yebhawodi, kanye nenani lobubanzi bomjikelezo wesikhungo sebholidi lincane ngangokunokwenzeka; Ukukhetha okunengqondo kwezinto ze-flange, umklamo jikelele we-flange kufanele ube ngangokunokwenzeka ukuze kuzuzwe umklamo ogcwele wokucindezeleka, ukufeza kokubili ukuphepha kanye nezinhloso zokonga izindleko.
Ngokuthuthuka okusheshayo kokwakhiwa kwamapayipi asekhaya, ukuhlolwa komfutho wepayipi sekube isixhumanisi esibalulekile. Ngaphambi nangemuva kokuhlolwa kwengcindezi, ingxenye ngayinye yepayipi kufanele ishanelwe yibhola, inani lezikhathi ngokuvamile liyi-4 ~ 5. Ikakhulukazi ngemva kokuhlolwa kwengcindezi, kunzima ukuhlanza amanzi agcinwe epayipini, ngakho izikhathi zokuhlanza zizoba Okuningi.
