Thermal Insulation of Distribution Pipelines
Abstract
In heat distribution systems, which are used to supply a heat-conveying medium to consumers, a certain amount of heat is always released to the surrounding environment. Such inevitable and undesired release of heat is referred to as heat loss. Heat loss causes that the medium flowing inside the distribution system cools down and its subsequent heating up is therefore more demanding. The consequences include higher costs of heat and hot water production not only for system operators but also for end consumers. Therefore, attention should be paid to thermal insulation when incorporated in heat distribution systems, primarily to its quality and thickness.

Introduction
A heat network is a pipeline system used to transport thermal energy, carried by a heat-conveying medium, from a source to an appliance. Thus, it is a system of buildings and equipment facilitating heat transport from central sources to heat consumers, regardless of their performance, nature and method of heat utilisation. A basic component of a heat network is a pipeline, including accessories.
Conclusion
Thermal insulation represents an integral part of heat distribution systems. Its role is to prevent heat escape to the surrounding environment and maintain the required temperature of the heat-conveying medium inside the pipeline. One of the tasks of insulation materials used in industrial applications is to reduce heat loss not only in the technological equipment but also in the heat distribution system. Cost-efficiency of the operation of pipeline systems, in terms of heat and technology, is most significantly affected by a proper choice of the insulation material and a correct calculation of the thickness of the selected insulation.
