Iiflange zemibhobho zenza ungqameko oluphuma ngokukhawuleza ukusuka ekupheleni kombhobho.Zinemingxuma emininzi evumela ukuba iiflange ezimbini zombhobho zibotshwe kunye, zenze unxibelelwano phakathi kwemibhobho emibini.Igasket inokufakwa phakathi kweeflange ezimbini ukuphucula itywina.
Iiflange zemibhobho ziyafumaneka njengeendawo ezidityanisiweyo ezisetyenziselwa ukujoyina imibhobho.I-flange yombhobho ifakwe ngokusisigxina okanye isigxina-ngokusisigxina ekupheleni kombhobho.Emva koko iququzelela ukudibanisa okulula kunye nokuchithwa kombhobho kwenye i-flange yombhobho.
Iiflange zombhobho zihlelwa ngokwendlela ezincanyathiselwe ngayo kumbhobho:
Iintlobo zeflange yombhobho ziquka:
- Weld intamo flangesiimpundu zidityaniselwe ekupheleni kombhobho, zibonelela ngeflange elilungele ubushushu obuphezulu kunye noxinzelelo.
- Iiflange ezinemisontoube nomsonto wangaphakathi (obhinqileyo), umbhobho ophothiweyo ukrwelwe kuwo.Oku kulula ukulingana kodwa akufanelekanga kuxinzelelo oluphezulu kunye nobushushu.
- I-socket-welded flangesube nomngxuma ongenanto kunye negxalaba ezantsi.Umbhobho ufakwa emngxunyeni ukuze ujike egxalabeni uze emva koko udityaniswe kwindawo kunye nefillet ejikeleze ngaphandle.Oku kusetyenziselwa imibhobho edayamitha encinci esebenza kuxinzelelo oluphantsi.
- I-slip-on flangeskananjalo ube nomngxuma ocacileyo kodwa ngaphandle kwegxalaba.I-Fillet welds isetyenziswe kumbhobho kumacala omabini e-flange.
- Iiflange eziphothiweyo cUkumelana namacandelo amabini;i-stubend kunye ne-flange exhasayo.I-subend i-butt-welded ukuya ekupheleni kombhobho kwaye ibandakanya i-flange encinci ngaphandle kwemingxuma.I-backing flange inokutyibilika phezu kwe-stubend kwaye ibonelele imingxuma yokubopha kwenye i-flange.Eli lungiselelo livumela ukuchithwa kwiindawo ezivaliweyo.
- I-flange eyimfamas luhlobo lwepleyiti engenanto ebotshelelwe kwenye iflange yombhobho ukwahlula icandelo lemibhobho okanye ukuphelisa imibhobho.
