Ama-flange angajwayelekileizinto ezingezona ezensimbi ezinezinga lokuphikisa elingekho ngaphansi kuka-1587 ℃. Kufanele yamukelwe ngokwezidingo zokwakheka komkhiqizo, futhi kufanele ihambisane nezindinganiso zamanje zempahla kazwelonke ezifanele. Ama-flange angajwayelekile athintwa ukunyakaza komzimba kanye nemishini endaweni yokushisa ephezulu, engabangela izenzakalo zokulimala njengokuncibilika, ukuthambisa, ukuqhekeka nokugqoka kwezinto eziphikisayo.
Kunezidingo eziqinile zenon-standard flangeizinto ezisetshenziswa ezicini ezilandelayo:
(1) izinga lokushisa lensimbi engagqwali nezingxenye ezincibilikisiwe liphezulu, ngeke kube khona ushintsho nezingxenye ezincibilikisiwe ekushiseni okusebenzayo;
(2) ingamelana nokucindezeleka okubangelwa ukusebenza kwezinga lokushisa eliphezulu, akukho ukulahlekelwa amandla esakhiwo, akukho deformation, akukho ukuphuka;
(3) umthamo uzinzile ekushiseni okuphezulu, hhayi ngenxa yokunwetshwa nokufinyela kokwakheka kwamatshe noma ukuqhekeka;
(4) ibenon-standard flangeayiphuli futhi iyaxebuka lapho izinga lokushisa lishintsha noma ukushisa kungalingani;
(5) kufanele abe nekhono elithile lokumelana nokuguguleka kwamakhemikhali;
(6) Kufanele ibe namandla anele nokumelana nokugqoka ukuze imelane nokubhodla kanye nomthelela wokushisa okuphezulu kanye nelangabi lesivinini esikhulu, intuthu kanye ne-slag;

Ama-flanges amakhulu amakhulukufanele ibe nokusebenza kahle, ingahlangabezana nezidingo zekhwalithi yokuxhuma izifakelo zamapayipi, futhi ihambisane nokuvikelwa komkhiqizo ofanele, imithetho yokuvikela ukuphepha kanye neziqondiso kanye nemininingwane yobuchwepheshe. Xhuma ukuminyana kwevolumu. Isilinganiso se-nozzle ye-non-standardi-flangeimikhiqizo kumthamo wayo ophelele, ukuminyana kweqiniso kubhekisela ekuvulekeni kwamavolumu embotshana ahlukahlukene ngaphandle kwezinye izingxenye zomsila wepayipi. Ukuqina kokuxhumeka kuvaliwe ngomkhawulo owodwa we-nozzle, kanti omunye umkhawulo uxhunywe nezwe langaphandle. Ikhono legesi lokudlula ku-nozzle ngokuphepha likuzinga lokushisa elilingana negumbi nangaphansi kwengcindezi ethile, ngokuvamile ilinganiswa nge-coefficient yokungena.
Izinto zokusetshenziswa ezingezona ezijwayelekilei-flangeI-diameter flange enkulu yizinto eziphikisayo, izinto ezimelana nokushisa okuphezulu, ukusebenza kahle kokuvala uphawu nezinye izinto ezijwayelekile zensimbi nezinsimbi ezingashisi. Ukukhetha okunengqondo kwezinto kudlala indima ebaluleke kakhulu ekuqinisekiseni ikhwalithi yezinto ezinkulu-ububanzi be-flangeimikhiqizo, ukusebenza okuphephile nokwezomnotho kanye nokwenza ngcono impilo yayo yesevisi.
