This Multi-Sized system makes an effective seal for purging pipework, across a wide range of large pipe diameters. Each Purge system covers multiple pipe sizes and schedules, resulting in fewer systems needed.

This is a professional robust solution for purging of stainless steel, duplex and other alloy pipework resulting in shiny, oxide free weld roots.

Seventeen Multi-size Inflatable Purge Systems cover pipe bore size 8 ½  - 80 inches (215 – 2035mm),compared with conventional inflatable systems which would require over seventy separate units.

With its “Plug and Purge Technology”, simply connect to a dedicated and regulated gas supply and choose any flow rate, up to 80 litres per minute, through the twin pre-set purge valve. A secondary gas supply hose can be used to purge though sintered outlets for even quicker purge times. Setup times are dramatically reduced.

Fast Purge has a unique connecting collar that reduces the volume of purge gas required resulting in quick and cost effective purging every time.

Before welding is commenced the system is easily pulled into position using the 4 rope loops at each end. It is positioned centrally to the root gap using the luminous strip in the centre of the system. This prevents the system from being positioned incorrectly.

The system only requires a single point connection to gas supply for both inflation and purging making it extremely simple to use.

Compared with rigid pipe purging systems the Multi-Size system is lightweight and collapsible for easy storage
