1. Mitundu yosiyanasiyana yowotcherera:
Slip Pa Flanges: fillet weld imagwiritsidwa ntchito kuwotcherera pakati pa chitoliro cha flange ndi flange.
Weld Neck Flanges: msoko wowotcherera pakati pa flange ndi chitoliro ndi wozungulira wowotcherera.
2. Zida zosiyanasiyana:
Slip On Flanges amapangidwa kuchokera ku mbale wamba yachitsulo yokhala ndi makulidwe okwaniritsa zofunika.
Weld Neck Flanges nthawi zambiri amapangidwa kuchokera kuzitsulo zopukutira.
3. Makakamizo osiyanasiyana mwadzina:
Kupanikizika mwadzina kwa Slip On Flanges: 0.6 - 4.0MPa
Kupanikizika mwadzina kwa Weld Neck Flanges: 1-25MPa
4.Mapangidwe osiyanasiyana
Slip On Flanges: amatanthauza flange yomwe imatambasula mapaipi achitsulo, zopangira zitoliro, ndi zina zambiri mu flange ndikulumikizana ndi zida kapena mapaipi kudzera muzowotcherera.
Weld Neck Flanges: flange yokhala ndi khosi ndi chitoliro chosinthira, chomwe chimalumikizidwa ndi chitoliro ndi kuwotcherera matako.
5. Kuchuluka kwa ntchito:
Slip Pa Flanges : imagwira ntchito pakulumikiza mapaipi achitsulo omwe ali ndi mphamvu yadzina yosapitilira 2.5MPa. Malo osindikizira a flange amatha kukhala mitundu itatu: mtundu wosalala, mtundu wa concave convex ndi mtundu wa mortise. Kugwiritsiridwa ntchito kwa flange yosalala ndi yaikulu Imagwiritsidwa ntchito makamaka pazochitika zapakati pakatikati, monga mpweya wochepa wosatsukidwa wosayeretsedwa ndi madzi otsika ozungulira.
Weld Neck Flanges : amagwiritsidwa ntchito powotcherera matako a flanges ndi mapaipi. Mapangidwe ake ndi omveka, mphamvu zake ndi kuuma kwake ndi zazikulu, zimatha kupirira kutentha kwakukulu ndi kupanikizika kwakukulu, kupindika mobwerezabwereza ndi kusinthasintha kwa kutentha, ndipo kusindikiza kwake ndikodalirika. Pakhosi, matako kuwotcherera flange ndi kuthamanga mwadzina kwa 1.0 ~ 16.0MPa utenga concave convex kusindikiza pamwamba.
The lathyathyathya kuwotcherera flange akhoza kokha chikugwirizana ndi chitoliro ndipo sangakhoze kugwirizana mwachindunji ndi matako kuwotcherera chitoliro; Zowotcherera matako nthawi zambiri zimatha kulumikizidwa mwachindunji ndi zida zonse zowotcherera matako (kuphatikiza zigongono, ma teti, mapaipi okhala ndi ma diameter osiyanasiyana, ndi zina), komanso mapaipi.
Kulimba kwa khosi lakuda kuwotcherera flange ndi wamkulu kuposa khosi lathyathyathya kuwotcherera flange, ndi matako kuwotcherera mphamvu ndi apamwamba kuposa lathyathyathya kuwotcherera flange, kotero si kophweka kutayikira.
Khosi lathyathyathya kuwotcherera flange ndi khosi matako kuwotcherera flange sangathe m'malo mwa kufuna. Ponena za kupanga, khosi la flat welding flange (SO flange) lili ndi zida zazikulu zamkati, zolemetsa zochepa komanso zotsika mtengo. Komanso, khosi matako-kuwotcherera flange ndi awiri mwadzina wamkulu kuposa 250 mm (WN ndi chidule cha WELDINGCHECK) ayenera kuyesedwa, kotero mtengo wake ndi otsika.
Kuwotcherera kwa lathyathyathya ndi khosi kumagwiritsidwa ntchito kwambiri pazida zamafuta zomwe zimatumizidwa kunja, zofanana ndi muyezo waku America S0. Ma flanges owotcherera matako amagwiritsidwa ntchito pazinthu zowopsa kwambiri.
Matako-kuwotcherera flange amatanthauza m'mimba mwake chitoliro ndi khoma makulidwe a kulumikiza mapeto, amene ali chimodzimodzi chitoliro kuti welded, monga mipope awiri ndi welded.
Flange yowotcherera yosalala ndi nsanja yopindika, dzenje lake lamkati ndilokulirapo pang'ono kuposa m'mimba mwake lakunja kwa chitoliro, ndipo chitolirocho chimalowetsedwa mu kuwotcherera mkati.
Kuwotcherera kwa lathyathyathya ndi kuwotcherera matako kumatanthawuza njira zowotcherera za flange ndi kulumikizana kwa chitoliro. Pamene kuwotcherera lathyathyathya kuwotcherera flange, mbali imodzi yokha kuwotcherera chofunika, ndipo palibe chifukwa kuwotcherera chitoliro ndi flange kugwirizana. Kuwotcherera ndi kuyika kwa flange yowotcherera kumafunika kuwotcherera mbali zonse za flange. Choncho, lathyathyathya kuwotcherera flange zambiri ntchito otsika kuthamanga ndi sing'anga kuthamanga mapaipi, ndi matako kuwotcherera flange ntchito sing'anga ndi mkulu kuthamanga chitoliro kugwirizana. Chowotcherera matako nthawi zambiri chimakhala PN2. 5 MPa, gwiritsani ntchito kuwotcherera matako kuti muchepetse kupsinjika. Nthawi zambiri, matako kuwotcherera flange amatchedwanso mkulu khosi flange ndi khosi flange. Choncho, mtengo unsembe, ntchito mtengo ndi katundu wothandiza mtengo wa kuwotcherera flange ndi mkulu, chifukwa pali njira imodzi yokha kuwotcherera flange.
