These
observation ports are for low-pressure applications
only.
The
Blast Gate Observation Ports use the Tate-Jones
standard line of blast gates as the primary component
and incorporates a glass lens, gaskets, and rings
that are securely retained with a metal bushing.
The
stainless steel slide arrangement in the blast
gate gives added protection and life to the lens
during operations, and allows maintenance to
be
performed with added safety during vessel down-time.
Additional
cooling can be obtained by adding a purge connection
on the glass or vessel side
of
the blast gate housing.
Three
choices of glass are available for varying temperature
exposures
and viewing requirements.
Threaded
sizes range from 2" to 6" NPT threaded openings.
