Iiflange zentamo zeWeldzezona ntlobo zeflange zidumileyo ezinolwandiso lwentamo olune-weld bevel ekupheleni. Olu hlobo lweflange lwenzelwe ukuwelda ngqo kwipayipi ukuze lubonelele ngonxibelelwano oluphezulu nolwendalo. Kwiisayizi ezinkulu kunye neeklasi zoxinzelelo oluphezulu, olu phantse luhlobo lonxibelelwano lweflange olusetyenziswayo kuphela. Ukuba bekukho isitayile esinye seflange esibolileyo kwizicelo zanamhlanje, intamo ye-weld ibiya kuba yiflange oyikhethileyo.
I-weld bevel idibana nesiphelo sombhobho nge-bevel efanayo kuqhagamshelo lohlobo lwe-V oluvumela i-weld ejikelezayo efanayo ejikeleze umjikelezo ukuze yenze utshintsho oludibeneyo. Oku kuvumela igesi okanye ulwelo ngaphakathi kwendibano yombhobho ukuba luhambe ngomda omncinci ngoqhagamshelo lweflange. Olu qhagamshelo lwe-weld bevel luhlolwa emva kwenkqubo ye-weld ukuqinisekisa ukuba itywina liyafana kwaye alinazo iimpazamo.
Olunye uphawu olubonakalayo lweflange yentamo ye-weld yi-hub enciphileyo. Olu hlobo loqhagamshelo lubonelela ngokusasazwa kancinci kancinci kwamandla oxinzelelo ecaleni kotshintsho ukusuka kumbhobho ukuya kwisiseko seflange, okunceda ukumelana noxinzelelo oluthile oluvela ekusebenziseni kwindawo yokusebenza enoxinzelelo oluphezulu kunye nobushushu obuphezulu. Uxinzelelo loomatshini lulinganiselwe ngenxa yezinto zentsimbi ezongezelelweyo ecaleni kotshintsho lwehabhu.
Njengoko iindidi zoxinzelelo oluphezulu zifuna olu hlobo loqhagamshelo lweflange phantse kuphela, iiflange zentamo ye-weld zihlala zenziwe nge-ring type joint facing (eyaziwa ngokuba yi-RTJ face). Lo mphezulu wokutywina uvumela ukuba i-metallic gasket icolwe phakathi kwemigca yeeflange zombini ezidibanisayo ukuze zenze i-superior seal kwaye ihambelane noqhagamshelo lwe-weld bevel olunamandla aphezulu kwi-pressurized pipe assembly. I-RTJ weld neck ene-metal gasket connect yeyona ndlela iphambili yokusetyenziswa okubalulekileyo.
