This Inflatable Pipe Purge System makes an effective seal for purging pipework prior to welding. Once in position the bags inflate forming a tight seal inside the pipe. When inflated the pre-set purge valve will open, releasing inert gas into the weld area.
This system is a professional robust solution for purging of stainless steel, duplex and other alloy pipework resulting in shiny, oxide free weld roots.
With its “Plug and Purge Technology”, simply connect to a dedicated and regulated gas supply and choose any flow rate, up to 20 litres per minute, through the pre-set purge valve. Setup times are dramatically reduced.
The system only requires a single point connection to gas supply for both inflation and purging making it extremely simple to use.
When ready to weld, the system is easily pushed or pulled into position and aligned at the pipe joint using the luminous strip to locate the system centrally to the root gap. This prevents the system from being positioned incorrectly.
As the pipe/tube is only purged between the inflated dams, lower gas volumes are required resulting in cost and time savings.
The modular construction makes for easy storage and cost effective part replacement.
