Speedline 25/50 Smoke Safe PVC Specifications
Hot Systems:
All piping fittings shall be insulated by filling the total void over all fittings, between straight runs of pipe insulation, with Speedline die-cut fiberglass insulation, forming a uniform insulation thickness equal to or exceeding the adjancent pipe insulation. Finish all insulated pipe fittings by applying Speedline Smoke Safe PVC Fitting Covers overlapping the adjacent pipe insulation outer covering. Secure the Speedling Fitting Covers with Speedline Stainless Steel Tack Fasteners, Speedline PVC Tape or by welding PVC overlaps with Speedline Vinyl Adhesive. Caution should be exercised to be sure that the insulation surface temperature is maintained below 150°F (66°C) through the application of sufficient insulation under all PVC covering.
Cold Systems:
All piping fittings shall be insulated by filling the total void over all pipe fittings between straight runs of pipe insulation with Speedling die-cut fiberglass insulation, forming a uniform insulation thickness equal to, or exceeding, the adjacent pipe insulation. Finish all insulated pipe fittings by applying Speedline Smoke Safe PVC Fitting Covers overlapping the adjacent pipe insulation outer covering. The overlap of the throat of the PVC Fitting Cover and the ends of the Fitting Cover overlapping the adjacent pipe insulation vapor barrier jacketing shall be vapor sealed with a compatible vapor barrier mastic. The ends of the PVC Fitting Cover overlapping the adjacent pipe insulation shall be further sealed by an outer wrapping of Speedline PVC Tape extending over the adjacent pipe insulation vapor barrier jacketing and overlapping its own juncture by at least two inches in the downward direction on the downward side.
