1. I-Mivel Diameter DN:
I-flangeI-Minoral Diameter isho ububanzi bendawo yesitsha noma ngepayipi nge-flange. Ububanzi besiqukathi besiqukathi bubhekisela kububanzi bangaphakathi kwesitsha (ngaphandle kwesitsha esine-tube njengesilinda sangaphakathi sepayipi, iningi lawo asondelene nobubanzi bepayipi. Ububanzi obungaphandle bepayipi lensimbi elinohlobo olufanayo lokuphakama, futhi ububanzi obungaphakathi buhlukile ngoba ubukhulu buyashintsha. 14 - Bheka Ithebula 1.

2. Ingcindezi yokuqothuka PN:
Ingcindezi yokuqothuka ibanga lengcindezi eyabelwe inhloso yokusungula indinganiso. 14 - Bheka Ithebula 2.
3. Ingcindezi ephezulu yokusebenza evunyelwe:
Ingcindezi yokuqothuka ku-Pressure Vessel Flange Standard inqunywa ngaphansi kwesimo seimpahla ye-flangeI-16mn (noma i-16MNR) ne-Design Temperature 200OC. Laphoimpahla ye-flangeFuthi ushintsho lokushisa, umfutho wokusebenza ovumayo we-flange uzokhuphuka noma wehlise. Isibonelo, ingcindezi ephezulu yokusebenza evunyelwe ye-butt welding welding welding ende iboniswa etafuleni 14-3.
