Double Seal Purging System, for 16 - 320mm Pipe I.D.
DSXX-X

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.

Features

• Typical purge times of less than 2 minutes (e.g. an 8” Pipe will purge to below 0.01% Oxygen in less than 2 minutes)
• High-quality silicon sealing disks that prevent them from tilting or falling over inside the pipe
• Guaranteed gas-tight seal
• UV and temperature resistance up to 330ºc continuously or 450ºc for short periods
• Suitable for purging pipes, elbows and fittings
• The silicon seal units can be separated and used as a gas finger and pipe stopper respectively
