1. I-Mivel Diameter DN:
I-flangeI-Minoral Diameter isho ububanzi bendawo yesitsha noma ngepayipi nge-flange. Ububanzi besikhombisi besiqukathi bubhekisela kububanzi be-Ingaphakathi lesitsha (ngaphandle kwesitsha esine-tube njengesilinda sayo sepayipi, okuyinani eliphakathi kobubanzi obuphakathi nobubanzi obungaphandle Ipayipi, iningi lazo eliseduzane 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.
