I-flangeUkukhetha kumele kuhlangabezane nezidingo zokuklama. Lapho umklamo ungadingi, kufanele ahambisane nohlelo lokucindezela okuphezulu, izinga lokushisa eliphakeme, elisebenza ngokusebenza,i-flangeIbanga lezinto ezibonakalayo nezinye izinto ezikhethiwe zokukhethwa kwefomu elifanele kanye nokucaciswa kwe-flange.
I-flangekumele ahlolwe ngaphambi kokufakwa, ingaphezulu kufanele kube bushelelezi, akusayikubakho izimbobo zesihlabathi, imifantu, amabala, ama-burrs nezinye izici ezinciphisa amandla we-flange, futhi ngeke kube khona imihuzuko ye- indawo yokubopha uphawu.
Lapho Ukuhlanganauhlobokanye namapayipi, sebenzisa umbusi we-Flange ukubheka i-verticality yeuhlobo. Laphoi-flangeUsayizi wokuphambuka wokuphambuka ohambelana awucacisiwe ekwakhiweni, akufanele kube mkhulu kune-1, 5% ye-Flange Direyimu, hhayi ngaphezulu kwe-2mm, lapho ama-flanges amabili engafani futhi angeqi izidingo zokucaciswa kufanele ziqonde, Musa ukusebenzisa ama-gaskets amaningi ukuze ulungise.
Laphoi-flangeI-Welded to the Pipeline, kufanele ifakwe ezinhlangothini zombili ngokuya ngezinga, futhi ukuphakama konyawo lwe-welding kufanele kuhlangabezane nezidingo.
