Pipes in building services systems and similar applications must be insulated in order to reduce the flow of heat to or from the medium carried by the pipes. This may be necessary for various reasons: Economic reasons: The cost of power losses to the surroundings can be balanced against the cost of greater insulation thickness, and an optimum thickness can be calculated. Surface temperature requirements: In the case of cold systems, the temperature difference between the surface of the pipes and the surroundings must be limited in order to avoid condensation. Limitation of temperature change: Industrial applications may have requirements in respect of the maximum temperature change of the transported medium that can occur. If insulation is to maintain its thermal insulating performance, it is important that any changes in the performance do not occur in an uncontrolled manner, but can be calculated. It is necessary, when calculating heat losses or temperature drops in a piping system, to know the insulating properties of the insulating material. The manufacturer needs to know the insulating performance characteristics of the material in order to provide the required product declaration.


To form insulated elbows with Pipe Section, the section is cut angles to form segments. The amount of segments depends on the size of the pipe and the angle of the elbow. When the pipe section segments are fitted around the pipe, they are secured with steel banding or wire ties per section. Any minor gaps between segments can be filled with pieces of Rock wool insulation.
