Double Seal Purging

Double Seal Purging Systems are the ideal solution when the application demands high-level quality end results. Widely used in the Nuclear industry, they are a great system when welding titanium and other exotic materials.

Proven to increase production time, and reduce gas & labour costs with typical purge times less than two minutes.

 

Features

  • Size Range: ¾ – 12″ (16 – 320mm)
  • High quality silicone discs
  • Guaranteed air tight sealing
  • UV and temperature resistant up to 320°C
  • Ideal for purging pipes, elbows, bends and fittings
  • Double seal systems are available individually, or in kits

How it works

The inlet and outlets have twin sealing discs joined by a flexible or rigid connector. Purging gas is diffused into the weld chamber, air exits through the secondary twin disc unit. The even flow of gas reduces turbulence and the risk of oxygen in the welding chamber.
