EZ-Purge Flex, manufactured by Orbimax, is a double seal purging system that works in the ranges from 25mm to 155mm. EZ-Purge Flex is easy to pull through pipes and bends without tilting. The design of the system also guarantees tha t at least one disc holds tight and this will reduce both purging time and inert gas use. Typical purge time of less than 2 minutes (for example an 8” pipe will purge to below 0,01% Oxygen in less than 2 minutes). Going from the welding of one pipe dimension to another, you simply change the sealing discs on the basic unit. Basic units are available in 3 lenghts, 120 mm, 150 mm and 200 mm. Each basic unit will fit all sizes of the sealing discs.
The Silicone Discs are temperature resistant up to 320°C.
