Title:
THERMOMETER PROTECTIVE CYLINDER, TEMPERATURE MEASUREMENT INSTRUMENT, STEAM PIPE STRUCTURE, AND METHOD FOR INSTALLING THERMOMETER PROTECTIVE CYLINDER
Document Type and Number:
WIPO Patent Application WO/2021/157141
Kind Code:
A1
Abstract:
The present invention provides a thermometer protective cylinder capable of suppressing a non-welded portion from being generated in a part to be welded. A thermometer protective cylinder is provided with: a cylinder main body (10) which has a rod-like shape extended in an axis line (X1) direction, and a tip (11) side of which is inserted into a through hole formed in a steam pipe; and a pipe stand portion (30), a diameter of which is expanded in a radial direction orthogonal to the axis line (X1) direction on a base end (12) side of the cylinder main body (10), the pipe stand portion (30) being disposed on an outer circumferential surface side of the steam pipe. The pipe stand portion (30) has a groove surface (31), a diameter of which is reduced from an outer circumferential side in a direction toward the tip (11) side from the base end (12) side of the cylinder main body (10), and a straight surface (32) which is extended in the axis line (X1) direction in a direction toward the base end (12) side from the tip (11) side of the cylinder main body (10) from the end portion of the cylinder main body (10) side of the groove surface (31), and is opposed to the outer circumferential surface of the cylinder main body (10) with a gap therebetween. The pipe stand portion (30) is provided with a groove portion (35) formed by the groove surface (31) and the straight surface (32) so as to be protruded.
