I-EN 1092-1 iyindinganiso ye-flange eyakhiwe yi-European Standardization Organisation (CEN), esebenza ekuxhumekeni kwe-flange ewuchungechunge namapayipi ensimbi nokufakwayo.Inhloso yaleli zinga ukuqinisekisa ukuthi ama-flange asetshenziswa emazweni ahlukahlukene aseYurophu anosayizi ofanayo nokusebenza.
Izinga le-EN 1092-1 licacisa izidingo zosayizi, ukwakheka, ingcindezi yamagama, impahla, indawo yokuxhuma, kanye nefomu lokuvala lezinhlobo ezahlukahlukene zamaflange ensimbi.Ibanga lokucindezela okulinganiselwe lisuka ku-PN2.5 kuya ku-PN100, futhi ububanzi bosayizi busuka ku-DN15 kuya ku-DN4000.Izinga liphinde licacise okokusebenza kwe-flange, okuhlanganisa insimbi, insimbi engagqwali, ithusi, ne-alloy yethusi.Ngaphezu kwalokho, izinga liphinde lihlanganise nezidingo zokuklama zeama-flanges anemicufuthii-blind flangeizixhumanisi, njengendawo yokuvala yokuxhumana kwe-flange nokuxhumana kwe-flange.
Izinga le-EN1092-1 liphinde licacise izindlela nezimfuneko zokuhlola ama-flange ukuze kuqinisekiswe ukuthi ayahlangabezana nezidingo zezinga.Ukuhlolwa kuhlanganisa ukuhlolwa kwe-hydrostatic, ukuhlolwa kokukhathala, ukuhlolwa kwe-torsion, nokuhlolwa kokuvuza.
Kuyaphawuleka ukuthi iI-EN1092-1 ejwayelekile isebenza kuphela kuma-flange ensimbi, futhi ayisebenzi kwezinye izinto kanye nezinhlobo zama-flange.Ngaphezu kwalokho, leli zinga lisebenza kuphela emakethe yaseYurophu, futhi ama-flange kwezinye izimakethe angase adinge ukuhambisana namazinga nemithetho ehlukene.
I-EN 1092-1 ilungele izinhlelo zokusebenza eziningi lapho kudingeka khona ukuxhumana kwamapayipi anengcindezi ephezulu kanye namazinga okushisa aphezulu, njengamasistimu wamapayipi ezimbonini ezinjengamakhemikhali, uphethiloli, igesi yemvelo, ukukhiqizwa kwamandla, ukwakha umkhumbi, i-aerospace, njalonjalo.Amasistimu wamapayipi kulezi zimo ngokuvamile adinga ukumelana nezimo ezicindezelayo ezifana nezinga lokushisa eliphezulu, umfutho ophakeme, ukugqwala, ukudlidliza, njll. Ngakho-ke, ukuxhunywa kwamapayipi kufanele kube namandla aphezulu, ukucinana okuphezulu, ukwethembeka okuphezulu, nokuphepha.
Izinga le-EN 1092-1 licacisa izidingo zosayizi, umumo, ingcindezi yegama, into, indawo yokuxhuma, kanye nefomu lokuvala lama-flange ensimbi ukuze kuqinisekiswe ukuthi ukusebenza kwawo kuhlangabezana nezidingo zezinhlelo zamapayipi ezinomfutho ophezulu kanye nezinga lokushisa eliphezulu.Le mithethonqubo ihlanganisa ukucindezela okuzisholo, ububanzi obuncane, indlela yokuxhuma, ifomu lokuvala, impahla, inqubo yokukhiqiza, indlela yokuhlola, njll. ye-flange.
Izinga le-EN1092-1 liyindinganiso ebanzi yase-Europe esebenza ekwakhiweni, ekwakhiweni nasekusetshenzisweni kwama-flange ensimbi emakethe yaseYurophu.Kwezinye izifunda, kukhona nezinye izindinganiso ze-steel flange, njenge-ANSI, i-ASME, i-JIS, njll. Uma ukhetha ama-flange, kuyadingeka ukuwakhetha ngokusekelwe ezidingweni ezithile zesistimu yamapayipi kanye namazinga asebenzayo.
