The Blast Gate Observation Ports use the 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 arrangment is the blast gate gives added protection and life to the lens during operation, 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.
