I-RTJ flange wuhlobo lwe-flange olusetshenziswa ekuxhumekeni kwamapayipi.I-RTJ isifinyezo se-Ring Type Joint, okusho ukuthi i-gasket evala indandatho.
Ama-RTJ flange ngokuvamile enziwe ngensimbi anemifantu eyindilinga ekhethekile nama-bevel ebusweni be-flange.Lesi sakhiwo singagcina ukusebenza kahle kokuvalwa kwe-flange ngaphansi kwezimo zokushisa eziphezulu nezingcindezi.
Ama-RTJ flange ajwayele ukusetshenziswa emikhakheni efana ne-petrochemical, ezokuthutha igesi yemvelo, kanye nokwakhiwa kwemikhumbi, futhi adinga ukumelana nezimo ezinzima ezifana nokucindezela okukhulu, izinga lokushisa eliphezulu, nokugqwala okuqinile.Ngokuvamile zixhunywe kumishini efana namapayipi, ama-valve, namaphampu, futhi zidlala indima ebalulekile kumaphrojekthi wobunjiniyela ahlukahlukene.
Izinhlobo ze-flange ezivamile zihlanganisawelding intamo flange, i-flange ebalulekile,i-blind flange, futhiI-American standard neck eshiselwe flange
Izindinganiso zamazwe ngamazwe ezivamile
I-ANSI B16.5
ASME B16.47 Uchungechunge A
ASME B16.47 Uchungechunge B
BS 3293
Izinga le-RTJ flange lakhiwe ngokusekelwe kulawa mazinga alandelayo:
1. Ipayipi lepayipi le-API phansi elihlangene (i-RTJ2 ejwayelekile: R-2, R-3, R4, R5, kanye ne-R-6)
2. Uchungechunge lwamasentimitha olujwayelekile lwamazwe ngamazwe: M-1, M-2, M-3, M-4, M-5, kanye ne-M-6
Nokho, kufanele kuqashelwe ukuthi kungase kube khona umehluko phakathiIzimpawu ze-RTJzamazinga ahlukene, kanye namamodeli afanelekile kanye nemininingwane kufanele kukhethwe ngokwezidingo zangempela lapho uzisebenzisa.
Isici samazinga we-RTJ flange yisidingo sokuqina, okuhlukaniswa kakhulu ngezinhlobo ezijwayelekile nezinamandla aphezulu.Isidingo sokujiya sohlobo oluvamile singu-100mm, kuyilapho ukujiya kohlobo lwamandla aphezulu kuphakeme, okungafinyelela ku-120mm noma ngaphezulu.
Kunezidingo ezithile ezikhethekile kuzinga le-RTJ flange, isibonelo, izinhlobo ezithile zamalunga zingase zidinge indawo yokuqinisa ekugcineni kwejoyini endaweni yenotshi ngesikhathi sokufakwa ukuze kugwenywe ukushelela.Ezinye izinhlobo ezikhethekile zamalunga, njengamajoyini aphezulu kakhulu, zingadinga futhi ukufakwa kohlangothi lwasentwasahlobo ukuze kwandiswe amandla e-axial.
Izinga le-RTJ flange lenza kube nokwenzeka ukuxhuma amapayipi nezinye izinto zokusebenza ezinengcindezi ephezulu, okwenza lonke uhlelo luphephe, luthembeke kakhudlwana, futhi luqine kakhudlwana.Inohlu olubanzi kakhulu lwezinhlelo zokusebenza futhi ingahlangabezana nezinhlobo ezahlukahlukene zezidingo zohlelo emikhakheni ehlukene.Ngokombono wokusebenza, enye yezinzuzo zaleli zinga ukuthi linciphisa isikhathi sokuxhunywa kwemishini yamapayipi ngesikhathi sokufakwa nokulungiswa, futhi lingandisa kakhulu ubude bamapayipi kuyilapho liqinisekisa ukuxhumana okuphephile, okwenza ukusebenza kuphephe.
