Uhlobo lwe-flange elizosetshenziselwa uhlelo lokusebenza lwamapayipi kuya ngokuthi, ikakhulukazi, ngamandla adingekayo okuhlanganiswa okuhlanganisiwe. Ama-Flanges asetshenziswa, kungenjalo ekuxhumaneni kwe-Welded, ukwenza lula ukusebenza kwesondlo (ukuhlangana okuhlangene kungadilizwa ngokushesha futhi kube lula).
