Ikhabhoniinsimbi flangengokwayo isakhiwo esihlangene, isakhiwo esilula, ukugcinwa kubuye kube lula kakhulu, indawo yokubeka uphawu kanye ne-spherical surface ngokuvamile isesimweni esivaliwe, akulula ukugezwa yi-medium, ukusebenza okulula nokugcinwa, okufanelekile kumakhemikhali, i-asidi, amanzi kanye negesi yemvelo kanye nokunye okujwayelekile okusebenzayo. I-flange eyenziwe nge-carbon steel ibizwa ngokuthi i-carboninsimbi flange. Ingaphezulu lekhabhoniinsimbi flangeyona ngokwayo iyisicaba futhi ibushelelezi, ayikho i-burr, ayiklwebheki, ayikho i-concave eguquguqukayo nezimo ze-convex.

Ipuleti lensimbi kufanele lihlolwe nge-ultrasonic, kungabikho zinkinga ze-delamination okufanele zisikwe lapho kuginqika khona umucu wensimbi, ukushisela izinqe zibe yindandatho, futhi kwenze ingaphezulu lendandatho yensimbi ibe yicylindrical. Ama-butt weld anezindandatho ezine-flanged entanyeni akufanele enziwe ngomshini ngokuqondile kusuka kumapuleti ensimbi, futhi ama-welds angena ngokugcwele azosetshenziswa. Ukusetshenziswa kwamabhawodi ensimbi ye-carbon akudingekile ukwengeza i-gasket yokufaka umgqomo kanye nomgqomo, kanye ne-insulation gasket kanye nomgqomo kusetshenziselwa kuphela ukuthi kungenzeka ukuthi uketshezi olukhethwayo noma lwephayiphi lukwazi ukuvutha futhi lube izikhathi eziqhumayo, lesi senzakalo sokukhetha amabhawodi ensimbi engagqwali futhi wengeza i-gasket yokufaka umgqomo nomphongolo.
