ASME B16.48 Spectacle Blind Flange Carbon Steel A515 Gr60 A105

Idatha Yomkhiqizo

Isingeniso Somkhiqizo

I-ASME B16.48 iyindinganiso eyimpumputhe ye-flange eyakhiwe yi-American Society of Mechanical Engineers (ASME), ifanele izinhlobo ezahlukene zamasistimu amapayipi.Phakathi kwabo, umbukwane blind flange ASME B16.48 uhlobo olukhethekile flange blind.
Iumbukwane blind flange, ebizwa nangokuthi i-octagon blind flange, yakhiwe ngama-octagon blind flange, ahlanganiswe ndawonye ngamabhawodi nama-gaskets phakathi.Umehluko phakathi kwe-spectacle blind flange kanye nezinye izinhlobo zama-blind flanges ukuthi inganikeza ukumelana nokucindezela okuphezulu nokusebenza kokuvala, kulungele igesi ephezulu yokucindezela kanye nezinhlelo zamapayipi oketshezi.
Isilinganiso sosayizi nengcindezi
Ngokwezinga le-ASME B16.48, ububanzi bebanga le-spectacle blind flange lisuka ku-1/2 intshi ukuya ku-24 inch, futhi isilinganiso sokucindezela singafinyelela ku-Class 150 (PN20), Class 300 (PN50), Class 600 (PN100), kanye ne-Class 900 (PN150).
Ububanzi bohlelo lokusebenza
I-ASME B16.48 ingaboni kahlewuhlobo olukhethekile lwezimpumputhe ezisetshenziswa ezinhlelweni zamapayipi, ikakhulukazi ezisetshenziselwa ukufakwa, ukugcinwa, nokuhlola ama-valve, amaphampu, izinsimbi, ama-flanges, nezinye izinto zokusebenza.
Ngokukhethekile, amakhethini e-ASME B16.48 asebenza kulezi zici ezilandelayo:
1. Ukuxhumeka kwe-Flange: Le puleti eliyimpumputhe lixhunywe ku-flange futhi lingasetshenziswa lapho kulungiswa noma kufakwa esikhundleni semishini ohlelweni lwamapayipi.Ingasebenza njengesici sokuvala sesikhashana ukuvimbela ukuvuza koketshezi ukuze kulungiswe noma kushintshwe izinto.
2. Ukufakwa kwemishini: Le plate eyimpumputhe ingase isetshenziselwe ukufaka imishini emisha.Uma zingekho izinto zokusebenza ohlelweni lwamapayipi kodwa okokusebenza kudingeka kufakwe, leli puleti eliyimpumputhe lingavala ipayipi okwesikhashana kuze kube yilapho ukufakwa kwawo kuqedwa futhi kuxhunywe ohlelweni lwamapayipi.
3. Ukuhlola ingcindezi: Le plate eyimpumputhe ingase isetshenziselwe ukuhlola ingcindezi yezinhlelo zamapayipi.Ngaphambi kokwenza ukuhlolwa kwengcindezi ohlelweni lwamapayipi, kuyadingeka ukuvala wonke ama-valve futhi usebenzise leli puleti eliyimpumputhe ukuze kusungulwe uhlelo oluvaliwe ohlelweni lwamapayipi ukuvimbela ukuvuza ngengozi ngesikhathi sokuhlolwa kwengcindezi.
Kafushane, i-ASME B16.48 i-spectacle blind iyisesekeli samapayipi esisebenza ngezindlela eziningi esisebenza ngokubanzi ekulungisweni kwesistimu yamapayipi, ukufakwa kwezinto zokusebenza, nokuhlola ingcindezi.
Izinzuzo kanye nokubi
Izinzuzo zihlanganisa:
1. Ukumelana nokucindezela okuqinile: Uma kuqhathaniswa nezinye izinhlobo zama-blind flanges, i-spectacle blind flange inganikeza ukumelana nokucindezela okuphezulu futhi ifaneleka ezinhlobonhlobo zegesi ezinomfutho ophezulu kanye nezinhlelo zamapayipi oketshezi.
2. Ukusebenza kahle kokuvala uphawu: ngenxa yokuthi yakhiwe ngamapuleti ayizimpumputhe ama-octagon amabili, ahlanganiswe ndawonye ngamabhawodi nama-gaskets phakathi, i-spectacle blind flange inomsebenzi omuhle wokuvala futhi ingavimbela ngempumelelo ukuvuza nokungcola.
Ububi:
1. Izindleko eziphezulu: Uma kuqhathaniswa nezinye izinhlobo zama-blind flanges, izindleko ze-spectacle blind flanges ziphakeme kakhulu.
2. Ukufakwa nokunakekelwa kuyinkimbinkimbi: Ukufakwa nokugcinwa kwe-spectacle blind flange kudinga amathuluzi amaningi nokusebenza, okuyinkimbinkimbi.
Sekukonke,I-ASME B16.48 umbukwane oyimpumputhe flangeukusebenza okuphezului-flange eyimpumputheilungele amasistimu ahlukahlukene wegesi anomfutho ophezulu kanye namapayipi awuketshezi, anezinzuzo ezifana nokumelana nokucindezela okuhle nokusebenza kokuvala.
