Ibipimo mpuzamahanga bya pipe flange ahanini bifite sisitemu ebyiri, arizo sisitemu yo mu Burayi ya flange flange ihagarariwe na DIN yo mu Budage (harimo n'icyahoze ari Leta Zunze Ubumwe z'Abasoviyeti) hamwe na sisitemu y'Abanyamerika y'Abanyamerika ihagarariwe na ANSI y'Abanyamerika.Byongeye kandi, hari imiyoboro ya JIS yo mu Buyapani JIS, ariko muri rusange ikoreshwa gusa mubikorwa rusange mubikorwa bya peteroli, kandi bifite ingaruka nke ugereranije n’amahanga.Noneho kwinjiza imiyoboro ya flanges mubihugu bitandukanye nibi bikurikira:

1. Imiyoboro ya sisitemu yu Burayi ihagarariwe n’Ubudage n’icyahoze ari Leta Zunze Ubumwe z'Abasoviyeti
2. Ibipimo bya sisitemu y'Abanyamerika imiyoboro ya flange, ihagarariwe na ANSI B16.5 na ANSI B 16.47
3. Ibipimo bya flange yu Bwongereza nu Bufaransa, buri gihugu cyibihugu byombi gifite ibipimo bibiri bifatika.

Muri make, ibipimo ngenderwaho mpuzamahanga bya pipe flange ku rwego mpuzamahanga birashobora kuvugwa muri make nka sisitemu ebyiri zitandukanye kandi zidashobora guhinduranya imiyoboro ya flange flange: imwe ni sisitemu y’iburayi ihagarariwe n’Ubudage;ikindi gihagarariwe na sisitemu yo muri Amerika ya pipe flange sisitemu.

IOS7005-1 ni igipimo cyatangajwe n’umuryango mpuzamahanga wita ku bipimo ngenderwaho mu 1992. Iyi ngingo ngenderwaho mu byukuri ni umuyoboro wa flange uhuza ibice bibiri bya flanges biva muri Amerika no mu Budage.
