I-1. Ububanzi be-DN:
IflangeUbubanzi bendawo ethengwayo bubhekisa kububanzi be-contreas okanye umbhobho ngeflethi. Ububanzi bonyulo besikhontelo sibhekisa kububanzi obungaphakathi besikhongozeli (ngaphandle kwesikhongozeli besilinda), ububanzi bombhobho bubhekisa kububanzi bayo, uninzi lwabo lusondele kumbhobho ongaphakathi. Ububanzi bangaphandle bombhobho wentsimbi kunye nobubanzi beentsimbi bekufana, kwaye ububanzi obungaphakathi kwahlukile kuba ubukhulu butshintsha. 14-Jonga itheyibhile 1.

2. Uxinzelelo olufanelekileyo pn:
Uxinzelelo olufanelekileyo libakala loxinzelelo olunikwe injongo yokuseka umgangatho. 14-Jonga itheyibhile 2.
3. Uxinzelelo oluvumelekileyo lokusebenza:
Uxinzelelo oluthile kumgangatho wenqanawa yenqanawa ye-Flange igqitywe phantsi kwemeko yeIzixhobo zeFlangeI-16mn (okanye i-16mnr) kunye ne-200oC ye-200C. XaIzixhobo zeFlangekunye notshintsho lobushushu, uxinzelelo oluvumelekileyo lokusebenza kwe-flange luya kunyuka okanye linciphe. Umzekelo, olona xinzelelo oluvumelekileyo olwenziweyo lwe-veling ye-welding ye-blalling iboniswe kwiTheyibhile 14-3.
