I-Flange Classification:
1. Izinto ze-Flange: i-carbon steel, i-cast steel, i-alloy steel, insimbi engagqwali, ithusi ne-aluminium alloy.
2. Ngendlela yokukhiqiza, ingahlukaniswa ibe yi-flange ehlanganisiwe, i-cast flange, i-welded flange, njll.
3. Ngokwezinga lokukhiqiza, lingahlukaniswa ngokwezinga likazwelonke (GB) (Izinga lomnyango wemboni yamakhemikhali, izinga le-petroleum, izinga lamandla kagesi), i-American Standard (ASTM), i-German standard (DIN), indinganiso yaseJapane (JB) , njll.
Uhlelo lukazwelonke olujwayelekile lwamapayipi ensimbi e-China yi-GB.
I-Flange Nominal Pressure: 0.25mpa-42.0mpa.
Uchungechunge lokuqala: PN1.0, PN1.6, PN2.0, PN5.0, PN10.0, PN15.0, PN25.0, PN42 (uchungechunge oluyinhloko).
Uchungechunge lwesibili: PN0.25, PN0.6, PN2.5, PN4.0.
Ifomu lesakhiwo se-Flange:
a.I-flat welding flange PL;
b.Welding flat ngentamo SO;
c.Butt welding flange WN;
d.I-socket weld flange SW;
e. I-flange evulekileI-PJ/SE;
f.Ishubhu edidiyelwe IF;
g.I-Flange enemicu TH;
h.Ikhava ye-Flange engu-BL, ikhava ye-flange yolwelwesi engu-BL (S).
Uhlobo Lwendawo Yokuvala I-Flange:indiza FF, i-RF ephakanyisiwe, i-concave surface FM, i-convex surface MF, ulimi ne-groove surface TG, indawo yokuxhuma indandatho i-RJ.
Isicelo se-Flange
I-Flat welded steel flange:ilungele ukuxhunywa kwepayipi lensimbi ye-carbon nengcindezi yokuzisholo engeqi ku-2.5Mpa.Indawo yokuvala ye-flange yokushisela eyisicaba ingenziwa ibe izinhlobo ezintathu: uhlobo olubushelelezi, uhlobo lwe-concave-convex kanye nohlobo lwe-language-and-groove.Ukusetshenziswa kwe-flange ye-welding ye-flat ebushelelezi yiyona enkulu kunazo zonke, futhi isetshenziswa kakhulu esimweni esiphakathi nendawo, njengomoya ocindezelwe ophansi ongahlanzekile kanye namanzi ajikelezayo anengcindezi ephansi.Inzuzo yayo ukuthi intengo ishibhile.
Butt Welding steel flange:Isetshenziselwa ukushisela izinqe ze-flange nepayipi.Inesakhiwo esinengqondo, amandla aphezulu kanye nokuqina, ingakwazi ukumelana nezinga lokushisa eliphezulu nokucindezela okuphezulu, ukugoba okuphindaphindiwe kanye nokuguquguquka kwezinga lokushisa, futhi inomsebenzi wokufaka uphawu okuthembekile.I-butt welding flange enengcindezi encane engu-0.25-2.5Mpa ithatha indawo yokuvala i-concave-convex.
I-socket welding flange:evame ukusetshenziswa kumapayipi ane-PN≤10.0Mpa kanye ne-DN≤40;
Ama-flange axekethile:ama-loose flange ajwayele ukubizwa ngokuthi ama-looper flanges, ama-welding welding looper flange, ama-flanging looper flange kanye nama-butt welding looper flange.Ivame ukusetshenziswa esimweni lapho izinga lokushisa eliphakathi nokucindezela lingekho phezulu futhi okuphakathi kudla kakhulu.Lapho okuphakathi kugqwala kakhulu, ingxenye ye-flange ethintana nendawo (i-flanging short joint) yenziwe ngezinto ezimelana nokugqwala ezisezingeni eliphezulu njengensimbi engagqwali, kanti ingaphandle liboshelwe izindandatho ze-flange zezinto ezisezingeni eliphansi njenge insimbi ye-carbon.ukufeza ukubekwa uphawu;
I-flange ehlanganisiwe:I-flange ivame ukuhlanganiswa nemishini, amapayipi, ama-valve, njll. Lolu hlobo luvame ukusetshenziselwa imishini nama-valve.
