Rupture disc changer QDC

ONIS Quick Rupture Disc Changer (QDC) developed by ONIS permit to one operator to be back in production with an optimal safe and precise overpressure relief system thanks to a rupture disc without using tools and permit to save equipment integrity, save production time and the efficiency of the pressure relief protection. One rupture disc is in line while the other is on hold outside of the pipe. As for a ONIS line blind, the gaskets are accessible for checks or change while the process is running. As soon as the rupture disc have been activated or need to be checked, After draining the pipe and open the by-pass, one operator will proceed as well as a standard ONIS Line blind : The flange’s spreading movement is generated by efficient and reliable synchronized eccentric shafts which allows the displacement of the slide gate equipped with two rupture disc holders. Nota : there are only 2 gaskets on the line. This quick-action clamping mechanism is self-locking and resistant to overpressure and vibration When your process is back in production, the maintenance team has all the time to change the activated rupture disc. Rupture discs are used in order to protect upstream installations from overpressure. The purpose of this pressure relief system is to blow up and keep the integrity of the assets. This rupture disc can be used as a primary level or secondary level. The main applications of rupture discs are in different industries as chemical, pharmaceutical, steel or power industries. Used in the primary level of protection, the rupture disc has to be changed each time it has been activated. Handling a QDC can be interesting if the frequency of activation is high.
