Kwintsimi yobunjineli bemibhobho, i-flanges, njengamacandelo abalulekileyo okudibanisa imibhobho, ineentlobo ezininzi zeentlobo kunye nemisebenzi. Phakathi kwazo, i-butt welded flanges ziye zaba "ziimveliso zeenkwenkwezi" kwiinkqubo zemibhobho yezoshishino ngenxa yokusebenza kwazo okugqwesileyo kunye neemeko ezibanzi zokusetyenziswa.

I-Welding flange, eyaziwa ngokuba yi-high neck flange, iyingqayizivele kuba intamo ende kunye nethambekele ephakamileyo isuka kwindawo ye-welding phakathi kwe-flange kunye nombhobho (njengoko kubonisiwe kumzobo we-schematic). Uyilo oluhlakaniphile lwale ntamo ephakamileyo alugcini nje ukunyusa ukuqina kunye namandla e-flange, kodwa kwakhona kunciphisa ngokufanelekileyo ukunyanzeliswa koxinzelelo, ukuqinisekisa ukuzinza kunye nokutywinwa kwe-flange kwindawo yoxinzelelo oluphezulu, oluphezulu, okanye oluphantsi. Uyilo lomngxuma wangaphakathi mkhulu kancinane kunodayamitha yangaphandle yombhobho, nto leyo eyenza kube lula ukuwelda iimpundu, ngelixa i-weld ye-weld ejikelezileyo inqumla ngaphakathi nangaphandle kweflange, iphucula ngakumbi ukusebenza kokutywinwa.

Ngenxa yolu ncedo loyilo, iiflange ezidityanisiweyo ze-butt zifanelekile ngokukodwa kwiinkqubo zoxinzelelo oluphezulu, ubushushu obuphezulu, okanye ubushushu obuphantsi kwiindawo zoshishino ezifana nepetroleum, iikhemikhali, kunye nokwakhiwa kweenqanawa. Iyakwazi ukumelana nokuguquguquka okukhulu koxinzelelo kunye nobushushu, ukuqinisekisa ukusebenza okuzinzileyo kombhobho. Okwangoku, ii-butt welded flanges zikwasetyenziswa ngokuqhelekileyo kwimibhobho yokuthutha izinto ezinokutsha, eziqhumayo, okanye ezinetyhefu, kwaye ukusebenza kwazo okuthembekileyo kokutywinwa kunika iziqinisekiso eziqinileyo zothutho olukhuselekileyo lweendaba.

Ngokwemigangatho yokuvelisa, iiflange ezidibeneyo ze-butt kufuneka zihambelane neemfuno ezingqongqo ezifana ne-JB4726-4728. Ngokutsho koxinzelelo oluqhelekileyo kunye nezixhobo, amabakala okukhwabanisa aqala kwiBakala I ukuya kwiBanga lesi-III ukuqinisekisa ukusebenza kwe-flange kwiindawo ezahlukeneyo zokusebenza. Ukongezelela, i-slope yangaphandle yentamo ye-welded flange akufanele idlule i-70 °. Le nkcukacha yoyilo inceda ukulawula ngokungqongqo iiparitha zobugcisa ngexesha lemveliso kunye neenkqubo ze-welding, zisebenzisa ngokupheleleyo indima kunye nexabiso leflange.
