FLANGE ISINGENISO

Imininingwane Engokwenyama
Okokuqala futhi okubaluleke kakhulu, i-flange kufanele ilingane nepayipi noma imishini eklanyelwe yona.Ukucaciswa ngokomzimba kwama-flange amapayipi kufaka phakathi ubukhulu kanye nokubunjwa kokuklama.

Ubukhulu be-Flange
Ubukhulu bomzimba kufanele bucaciswe ukuze ama-flange asayizi alungile.

Ububanzi bangaphandle (OD) yibanga eliphakathi kwamaphethelo amabili aphikisanayo obuso be-flange.
Ubukhulu busho ukujiya kwerimu yangaphandle enamathiselwe, futhi akubandakanyi ingxenye ye-flange ebambe ipayipi.
Ububanzi bendingilizi ye-bolt ubude obusuka phakathi nendawo yembobo yebhawodi ukuya phakathi nendawo yembobo ephikisanayo.
Usayizi wepayipi usayizi wepayipi ohambisanayo wepayipi, ngokuvamile owenziwa ngokwamazinga amukelwayo.Ivamise ukucaciswa izinombolo ezimbili ezingezona u-dimensional, usayizi wepayipi lokuzisholo (NPS) kanye neshejuli (SCH).
Usayizi we-bore wokuzisholo uwububanzi bangaphakathi besixhumi se-flange.Lapho ukhiqiza futhi uyala noma yiluphi uhlobo lwesixhumi sepayipi, kubalulekile ukufanisa usayizi we-bore wesiqephu nobukhulu bobhobho bepayipi lokuhlangana.
Ubuso be-Flange
Ubuso be-Flange bungakhiqizwa inani elikhulu lezidingo zokuklama ezenziwe ngokwezifiso.Ezinye izibonelo zihlanganisa:

Isicaba
Ubuso obuphakanyisiwe (RF)
Uhlobo lwendandatho ehlangene (RTJ)
I-O-ring groove
Izinhlobo zePipe Flanges
Amapayipi amapayipi angahlukaniswa abe yizinhlobo eziyisishiyagalombili ngokusekelwe ekuklanyeni.Lezi zinhlobo ziyimpumputhe, i-lap joint, i-orifice, i-reduction, i-slip-on, i-socket-weld, i-threaded, ne-weld neck.

Ama-blind flange angamapuleti ayindilinga angenawo amandla okubamba phakathi nendawo asetshenziselwa ukuvala iziphetho zamapayipi, ama-valve, noma amathuluzi.Basiza ekuvumeleni ukufinyelela kalula kulayini uma usuvaliwe.Zingabuye zisetshenziselwe ukuhlola ingcindezi yokugeleza.Ama-blind flange enziwe ukuze alingane namapayipi ajwayelekile kuwo wonke amasayizi ezilinganisweni zokucindezela okuphezulu kunezinye izinhlobo ze-flange.

Ama-flange ahlangene emathangeni asetshenziswa kumapayipi afakwe amapayipi agqitshwe noma anezinqe ezihlangene zamathanga.Angakwazi ukuzungezisa ipayipi ukuze avumele ukuqondanisa kalula kanye nokuhlanganisa izimbobo zamabholithi ngisho nangemva kokuba ukushisela sekuqediwe.Ngenxa yale nzuzo, ama-flange ahlangene e-lap asetshenziswa ezinhlelweni ezidinga ukuhlakazeka njalo kwama-flange namapayipi.Ayafana nama-slip-on flange, kodwa ane-radius egobile endaweni ebhorekile nasebusweni ukuze amukele isiphetho se-lap joint stub.Izilinganiso zokucindezela zama-lap joint flange ziphansi, kodwa ziphakeme kunama-slip-on flange.

Ama-slip-on flange aklanyelwe ukushelela ekugcineni kwamapayipi bese eshiselwa endaweni yawo.Banikeza ukufakwa okulula nokungabizi kakhulu futhi balungele izinhlelo zokusebenza zengcindezi ephansi.

Ama-socket weld flange alungele amapayipi amancane, anengcindezi ephezulu.Ukwakhiwa kwazo kufana nokushibilika kwe-flange, kodwa ukwakheka kwephaketheni langaphakathi kuvumela ukubhoboza okubushelelezi nokugeleza okungcono koketshezi.Uma eshiselwe ngaphakathi, lawa ma-flanges nawo abe namandla okukhathala angama-50% amakhulu kunama-flange ashiselwe kabili ashiselwe.

Ama-flange anezintambo yizinhlobo ezikhethekile ze-pipe flange ezingaxhunywa kwipayipi ngaphandle kokushisela.Acutshungulwa kubhore ukuze afane nentambo yangaphandle epayipini futhi ayacishwa ukuze enze uphawu phakathi kwe-flange nepayipi.Ama-welds ama-seal angasetshenziswa kanye nokuxhuma okunentambo ukuze kuqiniswe okwengeziwe nokuvala.Zisetshenziselwa kangcono amapayipi amancane nezingcindezi eziphansi, futhi kufanele zigwenywe ezinhlelweni ezinemithwalo emikhulu kanye nama-torque aphezulu.

Ama-flange entamo yokushisela anehabhu elide elicijile futhi asetshenziselwa izicelo zokucindezela okuphezulu.Ihabhu le-tapered lidlulisela ingcindezi isuka ku-flange iye kwipayipi ngokwayo futhi inikeza ukuqiniswa kwamandla okuphikisana ne-dishing.
