I-flange enemisontoibhekisa ku-aiflangeidityaniswe ngomsonto kunye nombhobho. Ngexesha loyilo, lunokuphathwa ngokukhululekileyoiflange. Inzuzo kukuba akukho welding efunekayo, kunye ne-torque eyongezelelweyo eveliswa yiiflangei-deformation kwi-cylinder okanye umbhobho incinci kakhulu. Ububi kukubaiflangeubukhulu bukhulu kwaye ixabiso liphezulu. Ilungele ukudityaniswa kombhobho woxinzelelo oluphezulu.

I-flange enemisontongumngxuma ongaphakathi weiflangeicutshungulwa ibe yintambo yombhobho, kwaye umbhobho onomsonto ohambelana noqhagamshelo olupheleleyo, luhlobo lweflange engadityaniswanga. Xa kuthelekiswa neflange yewelding ecaba okanye i-butt welding flange, iiflange enemisontoineempawu zofakelo kunye nokugcinwa okufanelekileyo, kwaye ingasetyenziswa kwezinye iipayipi ezingavumelekanga ukuba zifakwe kwi-weld kwisiza.
I-alloy steel flangesunamandla okwanelisayo, kodwa akukho lula ukuweld, okanye ukusebenza kwe-welding akulunganga,iiflange ezinemisontoingakhethwa kwakhona. Nangona kunjalo, kuyacetyiswa ukuba ungasebenzisi iiflange ezinemisonto ukunqanda ukuvuza phantsi kwemeko yokuba ubushushu bombhobho buguquka ngokukhawuleza okanye ubushushu bungaphezulu kwe-260℃ kwaye bungaphantsi kune -45℃.
