Waterproof Acoustic Fire Resistant High Temperature Perlite Preformed Insulation Pipes

Expanded perlite pipe is a non-asbestos,high performance and water repellent insulating material composed of high quality expanded perlite particles,bonded with inorganic binder and reinforcing fiber,and the technical specifications is leading in the level of similar products in domestic . The better water repellent property solves the technical problems effectively which complex with the various types of insulation, heat insulation and waterproof insulation, saving a lot of funds on construction and maintenance. It is widely used in power plants, petrochemical plant piping systems equipment, as well as heating pipe network system.ITEMPERLITEGranularity(mm)0.1-1.5Volume Weight(Kg/m³)200-300Heat Conductivity(W/m.k)0.047-0.054Fire-resistant limit(hours)1-2Bending strength(Mpa)≥0.8Compressive strength(Mpa)0.35-0.8Pelletizing Ratio(%)70-90Closed Cell Ratio(%)≥95Moisture Absorption50-85Service temperature-40~600℃perlite pipe is recommended for insulating piping, vessels and equipment. It is especially suited to the process piping, refractory use and in chemical plants and refineries. Its moisture resistance is particularly advantageous for installations in high humidity and high rainfall areas.
