Product DescriptionTAG - Inflatable Double Purge Bag SystemSizes: 2" to 24″ (50 to 600mm)Double Inflatable Pipe Weld Purging Systems Due to the design of these systems, the volume of gas used to purge is minimized. resulting in significant savings in both time and the quantity of inert gas used. Return on investment can be achieved in as little as just one or two welds.These robust systems can be used over and over again paying for themselves in very little time.
- PPM’s Inflatable Pipe Purging Systems dramatically reduce purging times leading to significant savings in labour costs.
- Typical purge times for 4″ pipe = 1½ mins; 8″ pipe = 4 mins; 12″ pipe = 8 mins
- Ready to use, connects to a dedicated and regulated gas supply. Choose any flow rate up to 20l a min. Through the pre-set purge valve
- Gas pressure control ensures an even positive root bead with no notching.
- Quick and easy to install simplifying the process of inert gas purging.
- Heat resistant up to 70ºC continuously
- Use less inert gas. The volume of purge gas used is less than 2% of that required for a conventional purge.
