Pipe insulation casing and its installation method

摘要

The present invention relates to the field of piping and equipment, and can be used in nuclear facilities, heating power engineering, mechanical engineering, petrochemical, water supply, chemical and aerospace industries, and various other technical fields. It is an object of the present invention to find a safe installation method for ensuring electrical insulation of the firewood casing and the insulating material for piping made of metal elements. It is an object of the present invention to achieve an object of the present invention in which the connection of the metal elements is made by overlapping, and in the overlapping area, the metal element is provided with a hole in which an electrically insulating gasket made of elastic, elastic plastic, plastic, sticky and partially hardened material is fixed. . When installing the casing, the material of the electrical insulating gasket is installed in the overlapping area. In this way, upon installation compression of each metal element, the electrically insulating gasket material fills the holes in the overlapping areas of the metal element. At the same time, a stable pin connection is formed between the gasket and the adjacent casing element. Pin connection ensures the fastening of adjacent metal elements without breaking their electrical insulation.
