Flange Gulu:
1. Zida za Flange: zitsulo za carbon, zitsulo zotayidwa, zitsulo za alloy, zitsulo zosapanga dzimbiri, mkuwa ndi aluminiyamu.
2. Pogwiritsa ntchito njira yopangira, ikhoza kugawidwa mu flange yonyezimira, flange yoponyedwa, flange yotsekemera, ndi zina zotero.
3. Malinga ndi muyezo wopanga, zitha kugawidwa mu standard standard (GB) (Ministry of chemical industry standard, petroleum standard, electric power standard), American Standard (ASTM), German standard (DIN), Japanese standard (JB) , ndi zina.
The dziko muyezo dongosolo la zitsulo chitoliro flanges ku China ndi GB.
The Flange Nominal Pressure: 0.25mpa-42.0mpa.
Mndandanda umodzi: PN1.0, PN1.6, PN2.0, PN5.0, PN10.0, PN15.0, PN25.0, PN42 (main series).
Series awiri: PN0.25, PN0.6, PN2.5, PN4.0.
Mawonekedwe a Flange:

b.Kuwotcherera lathyathyathya ndi khosi SO;
c.matako kuwotcherera flange WN;
d.Socket weld flange SW;
e. Kutaya flangePJ/SE;
f.Integral chubu IF;
g.Ulusi wa flange TH;
h.Chophimba cha flange BL, chivundikiro cha flange BL (S).
Mtundu Wosindikiza wa Flange:ndege FF, yokwezeka pamwamba RF, concave pamwamba FM, convex pamwamba MF, lilime ndi poyambira pamwamba TG, mphete yolumikizira pamwamba RJ.
Ntchito ya Flange
Flange welded steel flange:oyenera mpweya zitsulo chitoliro kugwirizana ndi kuthamanga mwadzina osapitirira 2.5Mpa.Malo osindikizira a flange yowotcherera amatha kupangidwa m'mitundu itatu: mtundu wosalala, mtundu wa concave-convex ndi lilime-ndi-groove.Kugwiritsidwa ntchito kwa flange yosalala yosalala ndikokulirapo, ndipo kumagwiritsidwa ntchito kwambiri pamikhalidwe yapakatikati, monga mpweya wocheperako wosayeretsedwa komanso madzi oyenda pang'onopang'ono.Ubwino wake ndikuti mtengo wake ndi wotsika mtengo.
Kuwotcherera matako chitsulo flange:Amagwiritsidwa ntchito powotcherera matako a flange ndi chitoliro.Ili ndi dongosolo loyenera, mphamvu yayikulu komanso yolimba, imatha kupirira kutentha kwambiri komanso kuthamanga kwambiri, kupindika mobwerezabwereza ndi kusinthasintha kwa kutentha, ndipo imakhala ndi ntchito yodalirika yosindikiza.The matako kuwotcherera flange ndi kuthamanga mwadzina kwa 0.25-2.5Mpa utenga concave-makutu otukukira kusindikiza kusindikiza pamwamba.
Socket welding flange:ambiri ntchito mapaipi ndi PN≤10.0Mpa ndi DN≤40;
Ma flanges omasuka:ma flanges otayirira amadziwika kuti looper flanges, zowotcherera mphete zowotcherera, zowotcherera zotchingira ndi matako.Nthawi zambiri amagwiritsidwa ntchito pamene kutentha kwapakati ndi kupanikizika sikuli kwakukulu ndipo sing'angayo imakhala yowonongeka kwambiri.Sing'angayo ikapsa kwambiri, mbali ya flange yomwe imalumikizana ndi sing'anga (flanging short joint) imapangidwa ndi zida zapamwamba zosapanga dzimbiri monga chitsulo chosapanga dzimbiri, ndipo kunja kwake kumangiriridwa ndi mphete za flange za zinthu zotsika kwambiri monga. carbon steel.kukwaniritsa kusindikiza;
Integral flange:Flange nthawi zambiri imaphatikizidwa ndi zida, mapaipi, ma valve, ndi zina zotero. Mtundu uwu umagwiritsidwa ntchito kwambiri pazida ndi ma valve.
