Iikhola ze-Grip zigxininiswe ngaphandle kokudibanisa okukhuselekileyo.Zinokomeleza uxinzelelo oluthwalwa yimibhobho.Imilinganiselo inokusuka kwi-DN50-DN300.Uxinzelelo lwebhere DN50-DN100 10 bar, DN150 -DN200 5bar, DN250-DN300 3bar.
Udityaniso lwe-No-hub lwenziwe ngobunjineli ukuqhagamshela umbhobho wentsimbi oyi-No-hub kunye nezifakelo, umbhobho wentsimbi kunye nemibhobho yeplastiki okanye imibhobho yobhedu. Ezi zidityanisiweyo ziquka i-elastomeric compound gasket ekumgangatho ophezulu egcinwe ngaphakathi kwikhaka lentsimbi emdaka.
Udibaniso lwe-No-hub lwenziwe ngobunjineli ukudibanisa umbhobho wentsimbi we-No-hub cast kunye nezixhobo, umbhobho wentsimbi kunye nemibhobho yeplastiki okanye imibhobho yobhedu.Udibaniso luqulathe umgangatho ophezulu we-elastomeric compound gasket egcinwe ngaphakathi kwekhaka lentsimbi engenasici.
