Ama-flange entamo e-Weldyizinhlobo ze-flange ezithandwa kakhulu ezinesandiso sentamo esine-bevel ye-weld ekugcineni. Lolu hlobo lwe-flange lwenzelwe ukushibiliza ngqo epayipini ukuze kuhlinzekwe uxhumano oluphezulu nolwemvelo. Ngosayizi abakhulu kanye nezigaba zokucindezela okuphezulu, lolu uhlobo loxhumano lwe-flange olusetshenziswa cishe kuphela. Ukube bekukhona isitayela esisodwa se-flange esinesithukuthezi ezisetshenziswayo zanamuhla, intamo ye-weld ibingaba yi-flange oyikhethayo.
I-weld bevel ihlangana ne-pipe end ene-bevel efanayo ekuxhumaneni kohlobo lwe-V okuvumela i-weld eyindilinga efanayo ezungeze umngcele ukuze yakhe uguquko oluhlanganisiwe. Lokhu kuvumela igesi noma uketshezi ngaphakathi kwe-pipe assembly ukuthi lugeleze ngomkhawulo omncane ngokuxhumeka kwe-flange. Lokhu kuxhumeka kwe-weld bevel kuhlolwa ngemuva kwenqubo ye-weld ukuqinisekisa ukuthi uphawu lufana futhi alunazo iziphambeko.
Esinye isici esiphawulekayo se-flange yentamo yokuwelda yi-hub enciphile. Lolu hlobo lokuxhuma luhlinzeka ngokusatshalaliswa kancane kancane kwamandla okucindezela ngokushintshela kusuka epayipini kuya phansi kwe-flange, okusiza ukumelana nokushaqeka okuthile okuvela ekusetshenzisweni endaweni yokusebenza enomfutho ophezulu kanye nokushisa okuphezulu. Ukucindezeleka komshini kunqunyelwe uma kubhekwa izinto zensimbi ezengeziwe ngokushintshela kwe-hub.
Njengoba amakilasi okucindezela okuphezulu adinga lolu hlobo lokuxhumeka kwe-flange cishe kuphela, ama-flange entamo ye-weld avame ukwenziwa ngobuso obufana nendandatho (okwaziwa nangokuthi ubuso be-RTJ). Lobu buso bokuvala buvumela ukuthi i-gasket yensimbi ichotshozwe phakathi kwemisele yama-flange womabili axhumanisayo ukuze kwakheke uphawu olungcono kakhulu futhi kuhambisane nokuxhumeka kwe-bevel ye-weld enamandla aphezulu ku-assembly yepayipi ecindezelwe. Intamo ye-weld ye-RTJ ene-gasket yensimbi iyindlela eyinhloko yokusetshenziswa okubalulekile.
