Principle of Operation
The
baffles comprise a pair of flexible seals on the rim of wheel like structure
fabricated of corrugated CrNi steel. A special gas diffuser produces a uniform
laminar flow of the purge gas into the space between the seals. There are two
different types of baffles depending on the seals used. The plus type has
deeper lips giving the baffle a wider range of us usable diameters to which it
can be applied. Also the deeper lips are better for dragging the baffles round
bends in the pipe.

These baffles are designed for
use in large cylinders and pipes starting at 145 mm (5.7") ID up to 1 meter (39
inches) ID. For smaller tubes click here The
baffles are used to contain and distribute the purge gas in the region of the
weld root. The environment in the root of the weld typically needs to contain
less than 50 ppm of oxygen in order to prevent oxidation. The purge baffles can
be used alone or in conjunction with an oxygen analyzer
to ensure a good welding environment on the back side of the weld.
