Non-standard flangesndi omwe amalumikizidwa ndi zotengera kapena mapaipi ndi kuwotcherera kwa fillet.Ikhoza kukhala iliyonseflange. Onani integral flangekapena looper flange molingana ndi kukhulupirika kwa mphete ya flange ndi gawo lolunjika.Flangemphete ili ndi mitundu iwiri: khosi ndi yopanda khosi.Poyerekeza ndikhosi matako flange, non-standard flangendizosavuta kupanga ndikusunga zinthu, koma kulimba kwake ndi kusindikiza kwake sikuli bwino ngati khosi la butt flange.Non-standard flangeschimagwiritsidwa ntchito polumikiza sing'anga ndi otsika kuthamanga ziwiya ndi mapaipi.
Non-standard flangendi oyenera otsika kuthamanga kalasi, kusinthasintha kuthamanga, kugwedera ndi zotsatira si kwambiri dongosolo mapaipi.Non-standard flangesamagwiritsidwa ntchito kwambiri chifukwa ndi osavuta kugwirizanitsa pa kuwotcherera ndi kusonkhanitsa ndipo ndi otsika mtengo.

Non-standard flangesndi mphete zopangidwa ndi zinthu zomwe zimatha kutulutsa pulasitiki ndikukhala ndi mphamvu.Ma gaskets ambiri amadulidwa kuchokera pamapepala omwe siachitsulo kapena amapangidwa molingana ndi fakitale yaukadaulo.Ndi bolodi la asbesitosi, bolodi la asbestosi, bolodi la polyethylene ndi zina zotero.Ndiwonso gasket yodzaza zitsulo zopangidwa ndi asibesitosi ndi zinthu zina zopanda zitsulo zokulungidwa ndi mbale yachitsulo yopyapyala (chitsulo, chitsulo chosapanga dzimbiri);Mtundu wina wa gasket umapangidwa ndi tepi yopyapyala yachitsulo ndi tepi ya asibesitosi yolumikizidwa pamodzi.General mphira gasket ndi oyenera nthawi ya kutentha m'munsimu 120 ℃;Rubber gasket ndi yoyenera kutentha kwa nthunzi pansi pa 450 ℃, kutentha kwamafuta pansi pa 350 ℃, nthawi zotsika.Pankhani ya 5MPa pansipa, mbale ya asibesito yolimbana ndi asidi imagwiritsidwa ntchito ngati sing'anga ya dzimbiri.
Pazida zothamanga kwambiri ndi mapaipi, ma gaskets achitsulo amtundu wa mandala kapena mawonekedwe ena opangidwa ndi mkuwa, aluminiyamu, chitsulo 10 ndi chitsulo chosapanga dzimbiri amagwiritsidwa ntchito.Non-standard flange gasket ndi kusindikiza nkhope kukhudzana m'lifupi ndi yopapatiza (mzere kukhudzana), kusindikiza nkhope ndi gasket processing kumaliza digiri ndi mkulu.
Kuphatikiza apo,osakhala muyezo flangeszingalepheretse dzimbiri pamwamba ndi ming'alu.Nthawi zambiri, mawonekedwe osakhazikika a flange amapangidwa ndi electroplated (zinki yachikasu, zinki yoyera, etc.), kapena yokutidwa ndi mafuta odana ndi dzimbiri, kupaka utoto wotsutsa dzimbiri.
