Non-standard flange ndi mtundu waflangemogwirizana ndi muyezo wadziko kapena milingo ina yakunja. Chifukwa muyezoflangesangathe kukwaniritsa zofunikira pazochitika zina zapadera, ndikofunikira kusintha ndikuwongolera mulingo winaflanges. Non-standard flange imapangidwa, ndipo pali zofunikira pakupanga kopanda muyezoflange.
Zipolopolo za zida za Chemical zitha kupangidwa ndi kuponyera,kupanga, kapena kuwotcherera, kapena popanga zigawo zingapo ndikuziphatikiza mu mgwirizano wotayika. Kapangidwe kameneka ndi mbali imodzi, ntchito yokonza ndondomeko yotsegulira kugwirizana kwa zosowa, komano ndi kupanga, kukhazikitsa ndi kukonza zosavuta. Pali zida zambiri zochotseka zolumikizira mu zida zamankhwala, monga kulumikizana kwa ulusi, kulumikizana kwa socket ndi kulumikizana kwa flange.
Kuchokera pamawonedwe, kugwirizana kwa flange kumaganiziridwa ngati kachitidwe, ndi kutayikira monga ndondomeko ya mapangidwe, kuyenera kukhala koyenera, koma kwa zaka zambiri, mapangidwe a phunzirolo adawonetsa kuti chifukwa cha zovuta zowonongeka kwa gasket, zimakhala zochepa kuposa nthawi ino, kotero tsopano mapangidwe a flange amachokera ku kulingalira kuchokera ku mphamvu, ndiko kulamulira kupsinjika kwa flange ndi kapangidwe kake.

Kuchokera pamawonekedwe apangidwe, ma flanges amatha kugawidwa m'mitundu itatu:
1. Flange yotayirira imatanthawuza kuti flange siikhazikika mwachindunji pa chipolopolo kapena chokhazikika koma sichingatsimikizire kuti flange mu chipolopolo chonsecho idzanyamula katundu wa bolt.
2. Zambiriflange, ndiko kuti, flange imapangidwa kapena kuponyedwa mu thupi limodzi mu chipolopolo, kapena chowotchereraflangeamagwiritsidwa ntchito kukhala thupi limodzi mu chipolopolo.
3. Flange iliyonse, kuchokera kumawonekedwe a mapangidwe, flange iyi imagwirizanitsidwa ndi chipolopolo chonse, ndipo kulimba kumakhala koipa kuposa flange yonse.
Ziribe kanthu mtundu wanjiflange, njira yake yowerengera mphamvu yopangira mphamvu ingaphatikizepo zovuta ziwiri zazikulu: imodzi ndi yakuti zigawo za mgwirizano wa flange ziyenera kukhala ndi mphamvu zokwanira. Chachiwiri, kugwirizana komweko kuyenera kutsimikiziridwa kuti kusindikiza.
