Flange Classification:
1. Flange zvinhu: carbon steel, cast steel, alloy steel, Stainless steel, mhangura uye aluminium alloy.
2. Nekugadzira nzira, inogona kukamurwa kuita flange yakaumbwa, yakakandwa flange, welded flange, nezvimwe.
3. Zvinoenderana neyakagadzirwa chiyero, inogona kukamurwa kuita chiyero chenyika (GB) (Ministry of chemical industry standard, petroleum standard, electric power standard), American Standard (ASTM), German standard (DIN), Japanese standard (JB) , nezvimwewo.
Iyo yenyika chiyero system yesimbi pombi flanges muChina ndeye GB.
Iyo Flange Nominal Pressure: 0.25mpa-42.0mpa.
Series one: PN1.0, PN1.6, PN2.0, PN5.0, PN10.0, PN15.0, PN25.0, PN42 (main series).
Series maviri: PN0.25, PN0.6, PN2.5, PN4.0.
Iyo Flange Structural Form:
a.Flat welding flange PL;
b.Flat welding nemutsipa SO;
c.Butt welding flange WN;
d.Socket weld flange SW;
e. Loose flangePJ/SE;
f.Integral chubhu IF;
g.Threaded flange TH;
h.Flange chivharo BL, lining flange chivharo BL (S).
Flange Seling Surface Type:ndege FF, yakasimudzwa pamusoro RF, concave pamusoro FM, convex pamusoro MF, rurimi uye groove pamusoro TG, mhete yekubatanidza pamusoro RJ.
Flange Application
Flat welded steel flange:inokodzera kabhoni simbi pombi yekubatanidza ine zita rekumanikidza isingapfuuri 2.5Mpa.Iyo yekuvharisa pamusoro peiyo flat welding flange inogona kugadzirwa kuita mhando nhatu: yakatsetseka mhando, concave-convex mhando uye rurimi-uye-groove mhando.Iko kushandiswa kweyakatsetseka flat welding flange ndiyo hombe, uye inonyanya kushandiswa kana iri pakati nepakati mamiriro, senge yakaderera-kudzvanywa isina kucheneswa yakamanikidzwa mhepo uye yakaderera-inotenderera inotenderera mvura.Kubatsira kwaro ndekwekuti mutengo wakaderera.
Butt welding simbi flange:Iyo inoshandiswa kugadzira butt welding yeflange uye pombi.Iine chimiro chinonzwisisika, simba repamusoro uye kusimba, inogona kumirisana nekushisa kwakanyanya uye kudzvanywa, kudzokororwa kukotama uye kushanduka kwekushisa, uye ine chisimbiso chakavimbika.Iyo butt welding flange ine zita rekumanikidza ye 0.25-2.5Mpa inotora concave-convex yekuisa chisimbiso pamusoro.
Socket welding flange:inowanzoshandiswa mumapaipi ane PN≤10.0Mpa uye DN≤40;
Loose flanges:loose flanges inowanzonzi looper flanges, split welding ring looper flanges, flanging looper flanges uye butt welding looper flanges.Inowanzoshandiswa mumamiriro ezvinhu apo tembiricha yepakati uye kudzvanywa haina kukwirira uye iyo yepakati inowedzera kuora.Kana iyo yepakati ichinyanya kuonda, chikamu cheflange chinobata pakati (flanging pfupi chibatanidza) chinogadzirwa nemhando yepamusoro-giredhi-inodzivirira corrosion zvinhu zvakaita sesimbi isina tsvina, uye kunze kunosungwa nemhete dzeflange dzezvinhu zvakaderera-giredhi senge. carbon steel.kuwana chisimbiso;
Integral flange:Iyo flange inowanzobatanidzwa nemidziyo, mapaipi, mavharuvhu, nezvimwewo Rudzi urwu runowanzoshandiswa mumidziyo nemavharuvhu.
