Estimating the term…
The invention relates to pipelines and equipment useful in nuclear power plants, heat power engineering, manufacturing engineering, petrochemistry, water supply, chemical and aerospace industries, and other fields. The invention relates to a pipe heat insulation casing consisted of metal elements and assembly method ensuring reliable electrical insulation of all elements. The connection of the metal elements is with lapping, the elements are with openings in the lapping area where the electrically-insulating spacers are set made of resilient, elastic-plastic, plastic, fully viscous or partially solidified material ensuring electrical insulation between the adjacent elements. The electrically-insulating spacers are applied to the lapping areas of the metal elements to fill the openings of the lapping areas thus arranging reliable pin connections between the spacer and adjacent casing elements. Multiple pin connections ensure fixation of the adjacent metal elements without any failure to electrical insulation of each other.
A pipe heat insulation casing in the form of cylindrical metal elements series-connected by electrically-insulating spacers, wherein metal elements are installed with mutual overlapping and with perforation openings in the mutual overlapping areas where electrically-insulating spacers are located which consider filling of the perforation openings in the lapping area in case of further compression.
An assembly method of pipe heat insulation casing, wherein they install series of cylindrical metal elements on the pipe with connection by means of electrically-insulating spacers, with difference that the metal elements are installed with overlapping with opening in the metal elements in the lapping areas and electrically-insulating spacers are set between the metal elements in the lapping areas with possibility of filling the openings of the metal elements in the lapping areas in case of further compression.
