I-Caliberi-flangeI-flange welding flange kanye neziphetho ze-butt weld zivame kakhulu i-flange enentambo ye-flange ayikho ekukhiqizweni kwangempela nokuthengiswa kwe-diameter enkulu, noma imikhiqizo yokushisela eyisicaba kakhulu ibalwa njengengxenye ye-welding eyisicaba yobubanzi obukhulu be-flange kanye ne-butt welding yesakhiwo esikhulu se-flange. futhi ukusetshenziswa uhla kuhlukile, kungabonisa izici kanye nezinzuzo nazo zizohluka, ngakho-ke uma ukusetshenziswa kufanele kusetshenziswe ngokuvumelana nobubanzi obuhlukene, ukuqinisekisa ukuthi i-flange idlala indima ebalulekile ye-flange ye-welding flat enobubanzi obungaqinile, ifanele ingcindezi p 4 mpa izikhathi;I-Butt welding flange, eyaziwa nangokuthi i-high neck flange, eqinile, ifanele izikhathi zokushisa eziphezulu.
Kunezinhlobo ezintathu zezindawo zokuvalwa kwe-flange: indawo evalekayo yendiza, elungele izikhathi ezingenabo ubuthi obuphakathi nendawo enengcindezi ephansi;Indawo evalekile kanye ne-convex yokuvala uphawu, ilungele izikhathi zengcindezi ephezulu; medium enobuthi nomfutho ophakeme, ububanzi ububanzi flange collocation nge fasteners asetshenziswa isicelo, okulandelayo wathi ukusetshenziswa izici ezimbili: okokuqala izici mechanical of enkulu ububanzi flange isitayela kufanele kube eduze isiqondiso rolling emva ukwelashwa ukushisa phezu blank ukweba. , ngakho-ke indawo enqanyuliwe yile: uma okungenalutho kungengaphezu kobubanzi obungama-40 mm, kufanele kube maphakathi nesampula; isampula ethathwe esikhungweni engxenyeni yesine yobubanzi izohlolwa ngamaqoqo futhi amantongomane azohlolwa ngamaqoqo ukuthi aqinile yini; Izinto zokusetshenziswa ezisetshenziselwa izibophelelo ezikhethekile zizoba nesitifiketi sokufaneleka somenzi.

I-Flange iyi-fasteners yokuqinisa futhi isetshenziswa kabanzi izingxenye zemishini zisetshenziswa kabanzi zonke izinhlobo zemishini yemishini yemishini ye-instrumentation yomkhumbi wesakhiwo samathuluzi okwakhiwa kwebhuloho lesitimela kanye nempahla efana ngenhla, ungabona zonke izinhlobo zokubopha, kuyisici sokucaciswa okuhlukahlukene izinhloso ezahlukahlukene, ukusebenza okuhlukile, kanye nochungechunge olujwayelekile lokuhlanganisa ububanzi obukhulu be-flange uhlobo lwedigri futhi kuyizinto zokubopha ezikhetheke kakhulu, uma ngokwenani lokuhlolwa kwesampula ngemuva kokwelashwa kokushisa, imiphumela yokuhlolwa izohambisana nezinhlinzeko ezifanele, futhi izoqinisekisa ukuthi izakhiwo zomshini zomkhiqizo azikho ngaphansi kokusebenza kwesimo sesampulaZonke izikhonkwane ezisetshenziselwa amaflange anobubanzi obukhulu anomfutho we-PN ongekho ngaphansi kuka-10.0MPa azohlolwa ngezinhlayiya kazibuthe ngokuya ngokuhlolwa okungabhubhisi kwengcindezi ye-JB 4730-1994 izitsha ngamunye ngamunye. Ngemuva kokuhlolwa, ngeke kube khona inkinga ngomkhiqizo, futhi uzohlangabezana nezidingo zama-flanges anobubanzi obukhulu be-forging yesibili.
