ELECTROTHERMAL INSULATING CONNECTING INSERT Russian patent published in 2018 - IPC F16L25/02 

FIELD: test equipment.

SUBSTANCE: invention relates to testing equipment and can be used for testing an object and its elements for simultaneous combined exposure of high-temperature loads in conditions of complete protection of testing equipment. Electrothermal insulating connecting insert consists of an inlet and an outlet flange with connecting threads on opposite ends and a hollow electrically insulating element in the form of a dielectric cylindrical bush fixed between flanges. Between the bush and flanges there are two high-temperature gaskets, clamped by means of pins and nuts with semi-rings, abutting the beads of the ceramic bush. Between the semi-rings there are two semi-rings of ceramic bricks glued together. All clamping metal elements are made with a coefficient of linear expansion equal to the coefficient of linear expansion of the material of the dielectric bush.

EFFECT: invention provides a simultaneous connection of required air volume with the specified parameters to the test object and protection of the equipment from charged parts of pipelines.
