Thermal insulation of pipelines. Thermal insulation of pipes.
Thermal insulation of pipes is intended for reduction of losses of heat in pipelines and warmly networks, and also for maintenance of the set heat carrier temperature. Thermal insulation of pipes is used as protection against formation of high temperatures on a surface of pipes, heat conductors, the equipment. Reduction of transport losses of heat is the main means of economy of fuel. Considering rather small costs of thermal insulation of pipes (5... 8% of capital investments in construction of thermal networks), very important in questions of preservation of the transported heat on pipes are their covering high-quality and effective heat-insulating materials. Heat-insulating materials and designs directly contact to the environment which is characterized by fluctuations of temperature, humidity, and at underground laying - aggressive effects of ground waters in relation to a surface of pipes.
