Here hot and cold insulation in piping he material in high temperature insulation allows water to enter because the heat will cause the moisture to evaporate. However, in a cold insulation system, the water will not evaporate. Closed cell structure of the cold insulation material helps prevent this problem. Common fibrils used in piping insulation are Silica, slag wool, rock wool, and alumina-silica. Among these, Glass fiber and Mineral Wool are the two most widely used piping insulation of this type. Their fibers are normally bonded with organic binders for structural integrity. Pipe insulation materials can be used to encase piping mechanisms that cause noises or vibrations, forming a sound and vibration barrier between the piping and external areas. for more details download this file .
