1. PURPOSE
1.1 This global engineering specification defines and describes the minimum requirements for the thermal insulation system for cellular glass for use on piping or equipment operating in dual temperature service above and below ambient dew point.
2. scope
2.1 This specification applies to all piping in dual temperature services and in hot oxygen service that is external to cold boxes. Dual temperature service operates above the ambient dew point part of the time and below the ambient dew point part of the time. It covers all preformed and slab cellular glass insulation materials including adhesives, sealers, mastics, and jackets. This insulation material is identified on drawings with one of the following symbols: D2 – hot piping or equipment for the prevention of heat loss (see 4WPI-INS005) D3 – hot piping or equipment for personnel protection (see 4WPI-INS005)
