Suxulka Birta Aan Lahayn
Heerarka flange dhuumaha caalamiga ah inta badan waxay leeyihiin laba hab, kuwaas oo ah nidaamka flange tuubooyinka Yurub matalaya DIN Jarmal (oo ay ku jiraan Midowgii Soofiyeeti hore) iyo nidaamka flange ee Maraykanka oo u taagan flanges American ANSI.Intaa waxaa dheer, waxaa jira jajabyada tuubooyinka JIS ee Japan, laakiin guud ahaan waxaa loo isticmaalaa oo kaliya shaqooyinka guud ee dhirta petrochemical, waxayna leeyihiin saameyn yar oo caalami ah.Hadda soo bandhigida flanges tuubooyinka dalal kala duwan waa sida soo socota:
1. Tuubooyinka nidaamka Yurub oo ay matalaan Jarmalka iyo Midowgii Soofiyeeti ee hore
2. Heerarka flange nidaamka Ameerika, oo ay matalaan ANSI B16.5 iyo ANSI B 16.47
3. Heerarka flange tube Ingiriis iyo Faransiis, mid kasta oo ka mid ah labada waddan waxa uu leeyahay laba halbeeg flange.
Marka la soo koobo, heerarka flange dhuumaha caalamiga ah ee caalamiga ah waxaa lagu soo koobi karaa sida laba nidaamka flange tuubooyinka kala duwan iyo kuwa aan la beddeli karin: mid waa nidaamka flange tube Yurub wakiil Germany;Midda kale waxaa matalaya nidaamka flange tube ee Maraykanka.
IOS7005-1 waa halbeeg ay soo saartay Ururka Caalamiga ah ee Habaynta 1992. Halbeeggani dhab ahaantii waa halbeegga tubooyinka tubooyinka oo isku daraya laba qaybood oo tubbo taxane ah oo ka yimid Maraykanka iyo Jarmalka.
