I-1. Ububanzi be-DN:
IflangeUbubanzi bendawo ethengwayo bubhekisa kububanzi be-contreas okanye umbhobho ngeflethi. Ububanzi bonyulo besikhontelo sibhekisa kububanzi obungaphakathi besikhongozeli (ngaphandle kwesikhongozeli njengesilinda), ububanzi bombhobho bubhekisa kububanzi be-iphakathi kunye nobubanzi be Umbhobho, uninzi lwazo lusondele kakhulu kumbhobho wangaphakathi wombhobho. 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.
