Certain instructions and illustrations are provided here to assist the specifier. A. General 1. A pipe coating system may be recommended to minimize the likelihood of pipe corrosion (CUI). Consult with the designer or engineer before beginning installation of the insulation system. 2. All insulation shall be tightly butted and free of gaps and voids at all joints. 3. Pre-fabricated insulation fittings for elbows, tees, and valves, shall be the same thickness at fittings as pipe sections. 4. Each layer of insulation shall be secured to the pipe with 3/4" wide fiber reinforced tape. If factory applied facings are used, fiber reinforced tape in not required on the outer layer. (Figure 4, Appendix A) 5. Vapor barrier performance is extremely important; the vapor retarder shall be continuous. 6. Vapor stops shall be used on either side of valves frequently removed for servicing, valve stations left exposed, or odd fittings, elbows, tees, etc. where the chance of moisture infiltration is high. (Figure 2, Appendix A) 7. Before outer jacketing can be installed on a portion of the piping, the vapor retarder system on that portion shall be complete. 8. All tape, fasteners, and bands shall be neatly aligned and installed in a workmanlike manner by skilled and experienced workers who are regularly engaged in ammonia refrigeration insulation work.
