Patent ID: 11739880

Abstract:
A concentric, multi-layer laminated wrap for protection of plastic pipes including up to 60-minute fire endurance, low flame spread, low smoke, and toxic products of combustion. The laminated wrap can withstand temperatures up to 2000° F. for up to a period of 60 minutes. The concentric laminated wrap includes an inner support layer that provides strength, an intermediate fire protective coating layer that provides fire, heat, and high temperature protection, and an outer top coating layer that provides resistance to abrasion, impact, and environmental factors including water, salt water, hydrocarbons, chemicals, and gases. The protection to plastic pipes and pipe appliances is provided by the fire protective coating layer that is applied directly to the pipe or as a layer in the laminated wrap around the pipe. The present invention is disclosed for fire, heat, and high temperature protection of pipes, including linear pipes and pipe appliances such as flanges, couplings, valves, joints, tees, and bends.
