PIPE FOR GAS MEASUREMENT, AND METHOD OF MANUFACTURING THE SAME

摘要

PROBLEM TO BE SOLVED: To easily install an optical window for accurately performing spectroscopic measurement in an actual plant without requiring a troublesome processing construction for disposing the optical window corresponding to the type for laser beam irradiation in a pipe to be measured in the actual plant in a factory having the actual plant.SOLUTION: The pipe for gas measurement includes: a pipe member 11 disposed at a predetermined position of an actual pipe 1 to be measured; an incident hole 12 and outgoing hole 13 that penetrate the pipe member 11 in the traverse direction; an incident pipe 14 and outgoing pipe 15 whose base end parts 14B and 15B are attached to the pipe member 11 around the incident hole 12 and outgoing hole 13 and which surround the center axis C1 of the incident hole 12 and outgoing hole 13, respectively; and a flange 16 for blocking the tips of the incident pipe 14 and outgoing pipe 15.
