Iiflange zepayipi zenza umqolo ophuma ngokukhawuleza esiphelweni sombhobho. Zinemingxuma eliqela evumela ukuba iiflange ezimbini zepayipi zidityaniswe kunye, zenze unxibelelwano phakathi kweepayipi ezimbini. I-gasket ingafakwa phakathi kweeflange ezimbini ukuphucula isitywino.
Iiflange zepayipi ziyafumaneka njengeendawo ezahlukeneyo zokusetyenziswa ekudibaniseni iipayipi. Iflange yepayipi incamathiselwa ngokusisigxina okanye ngokusisigxina esiphelweni sepayipi. Emva koko yenza kube lula ukuhlanganisa nokuqhawula umbhobho kwenye iflange yepayipi.
Iiflange zepayipi zahlulwe ngokwendlela ezincamathiselwe ngayo kumbhobho:
Iindidi zeflange yombhobho ziquka:
- Iiflange zentamo zeWeldzifakwe izinqe ezixineneyo ekupheleni kombhobho, zibonelela ngeflange efanelekileyo kubushushu obuphezulu kunye noxinzelelo.
- Iiflanges ezinemisontoUkuba inentambo yangaphakathi (yomfazi), umbhobho onentambo ufakwe kuyo. Kulula ukuyifaka kodwa ayifanelekanga kuxinzelelo oluphezulu kunye nobushushu.
- Iiflanges ezidityaniswe ngesokhethiinomngxuma ocacileyo onegxalaba ezantsi. Umbhobho ufakwa emngxunyeni ukuze ujikeleze igxalaba uze emva koko udityaniswe endaweni yawo nge-fillet weld ejikeleze ngaphandle. Oku kusetyenziswa kwiipayipi ezincinci ezinobubanzi obuphantsi ezisebenza ngoxinzelelo oluphantsi.
- Iiflange ezityibilikayoikwanayo nomngxuma ocacileyo kodwa ongenagxalaba. Ii-fillet welds zifakwa kumbhobho kumacala omabini eflange.
- Iiflange ezidibeneyo cI-subbend ixhomekeke kwiindawo ezimbini; i-stubend kunye ne-backing flange. I-subend idityaniswe nge-butt-welded ukuya esiphelweni sombhobho kwaye ibandakanya i-flange encinci engenamingxunya. I-back flange ingatyibilika phezu kwe-stubend kwaye inike imingxunya yokubophelela kwenye i-flange. Olu lungiselelo luvumela ukuqhekeka kwiindawo ezivalekileyo.
- I-flange eyimfamaii-s luhlobo lwepleyiti engenanto ebotshelelwe kwenye iflengi yombhobho ukuze yahlulwe icandelo lombhobho okanye iphele imibhobho.
