This unit mounts to a mating flange on 3" or 4" pipe, while the viewing components are housed in a NPT threaded body half. The standard stainless steel slide arrangement in 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. Fabrication in alternative materials is available upon request.
