Chiyambi choyambirira cha flange
Mapaipi flanges ndi gaskets awo ndi zomangira pamodzi amatchedwa flange joints.
Ntchito:
Kulumikizana kwa Flange ndi mtundu wa chigawo chomwe chimagwiritsidwa ntchito kwambiri pakupanga uinjiniya.Ndi gawo lofunikira pamapangidwe a mapaipi, zoyikapo mapaipi ndi mavavu, komanso gawo lofunikira la zida ndi zida (monga manhole, geji yoyezera magalasi, ndi zina).Kuphatikiza apo, zolumikizira za flange nthawi zambiri zimagwiritsidwa ntchito pazinthu zina, monga ng'anjo zamafakitale, uinjiniya wamatenthedwe, madzi ndi ngalande, kutentha ndi mpweya wabwino, kuwongolera zokha, etc.
Kapangidwe kazinthu:
Chitsulo chonyezimira, WCB carbon steel, chitsulo chosapanga dzimbiri, 316L, 316, 304L, 304, 321, chrome-molybdenum steel, chrome-molybdenum-vanadium steel, molybdenum titaniyamu, mphira akalowa, fluorine akalowa zipangizo.
Gulu:
Flat kuwotcherera flange, khosi flange, matako kuwotcherera flange, mphete kulumikiza flange, socket flange, ndi akhungu mbale, etc.
Executive Standard:
Pali mndandanda wa GB (mtundu wa dziko), mndandanda wa JB (dipatimenti yamakina), mndandanda wa HG (dipatimenti yamankhwala), ASME B16.5 (American standard), BS4504 (British standard), DIN (German standard), JIS (Japanese standard).
International chitoliro flange muyezo dongosolo:
Pali mitundu iwiri ikuluikulu ya mayiko chitoliro flange mfundo, ndicho European chitoliro flange dongosolo akuimiridwa ndi German DIN (kuphatikiza kale Soviet Union) ndi American chitoliro flange dongosolo akuimiridwa ndi American ANSI chitoliro flange.
1. Mbale mtundu lathyathyathya kuwotcherera flange
ubwino:
Ndizosavuta kupeza zida, zosavuta kupanga, zotsika mtengo komanso zogwiritsidwa ntchito kwambiri.
Zoyipa:
Chifukwa cha kusasunthika kwake, sayenera kugwiritsidwa ntchito m'makina opaka mapaipi opangira mankhwala omwe ali ndi zofunikira pazakudya ndi zofunidwa, kuyaka, kuphulika ndi digiri ya vacuum yayikulu, komanso pamalo owopsa kwambiri.
Malo osindikizira amakhala ndi malo athyathyathya komanso owoneka bwino.
2. Flange kuwotcherera flange ndi khosi
The slip-on kuwotcherera flange ndi khosi ndi wa dziko muyezo flange dongosolo muyezo.Ndi mtundu umodzi wa flange wamtundu wa dziko (womwe umadziwikanso kuti GB flange) ndi imodzi mwama flange omwe amagwiritsidwa ntchito pazida kapena mapaipi.
ubwino:
Kuyika pa malo ndikosavuta, ndipo njira yowotcherera msoko imatha kuchotsedwa
Zoyipa:
Kutalika kwa khosi la flange yolowera pakhosi ndi khosi kumakhala kochepa, komwe kumapangitsa kuti flange ikhale yolimba komanso yobereka.Poyerekeza ndi matako kuwotcherera flange, ntchito kuwotcherera ndi lalikulu, kumwa kuwotcherera ndodo ndi mkulu, ndipo sangathe kupirira kutentha ndi kuthamanga, kupindika mobwerezabwereza ndi kusinthasintha kutentha.
3. khosi matako kuwotcherera flange
Mitundu yosindikizira yamtundu wa neck butt welding flange ndi:
RF, FM, M, T, G, FF.
ubwino:
Kulumikizana sikophweka kupunduka, kusindikiza kwake ndikwabwino, ndipo kumagwiritsidwa ntchito kwambiri.Ndi yoyenera mapaipi omwe amasinthasintha kwambiri kutentha kapena kuthamanga, kutentha kwambiri, kuthamanga kwambiri komanso kutentha pang'ono, komanso mapaipi onyamula zinthu zotsika mtengo, zoyatsira ndi zophulika, komanso mpweya wapoizoni.
Zoyipa:
Chowotcherera khosi pakhosi ndi chokulirapo, chokulirapo, chokwera mtengo, komanso chovuta kuyiyika ndikuchipeza.Chifukwa chake, ndikosavuta kugunda pamayendedwe.
4. Socket kuwotcherera flange
Socket kuwotcherera flangendi flange welded ndi chitsulo chitoliro mbali imodzi ndi bolts mbali ina.
Mtundu wa pamwamba wosindikiza:
Nkhope yokwezeka (RF), nkhope ya concave ndi convex (MFM), nkhope ya tenon ndi groove (TG), nkhope ya mphete (RJ)
Kuchuluka kwa ntchito:
Boiler ndi kukakamiza chotengera, mafuta, mankhwala, shipbuilding, mankhwala, zitsulo, makina, kuponda chigongono chakudya ndi mafakitale ena.
Amagwiritsidwa ntchito pamapaipi okhala ndi PN ≤ 10.0MPa ndi DN ≤40.
5. Ulusi wa flange
Flange yopangidwa ndi ulusi ndi flange yopanda ulusi, yomwe imayendetsa bowo lamkati la flange kukhala ulusi wa chitoliro ndikulumikizana ndi chitoliro cha ulusi.
ubwino:
Poyerekeza ndi kuwotcherera lathyathyathya flange kapena matako kuwotcherera flange,flange ya ulusiali ndi makhalidwe abwino unsembe ndi kukonza, ndipo angagwiritsidwe ntchito pa mapaipi ena amene saloledwa kuwotcherera pa malo.Aloyi chitsulo flange ali ndi mphamvu zokwanira, koma si kophweka kuwotcherera, kapena kuwotcherera ntchito si bwino, flange ulusi akhoza kusankhidwanso.
Zoyipa:
Pamene kutentha kwa payipi kumasintha kwambiri kapena kutentha kuli pamwamba pa 260 ℃ ndi kutsika kuposa -45 ℃, tikulimbikitsidwa kuti musagwiritse ntchito flange ya ulusi kuti mupewe kutayikira.
6. Akhungu flange
Imadziwikanso kuti chivundikiro cha flange ndi mbale yakhungu.Ndi flange yopanda mabowo pakati kuti asindikize pulagi ya chitoliro.
Ntchitoyi ndi yofanana ndi ya welded mutu ndi ulusi chitoliro kapu, kupatulapokhungu lakhungundi ulusi chitoliro kapu akhoza kuchotsedwa nthawi iliyonse, pamene welded mutu sangathe.
Flange chivundikiro chosindikizira pamwamba:
Yathyathyathya (FF), nkhope yokwezeka (RF), nkhope yopindika ndi yowoneka bwino (MFM), nkhope ya tenon ndi groove (TG), nkhope yolumikizira mphete (RJ)
