Abstract

Provided is a vapor pipe break detection device for the early detection of damage to a vapor pipe through which vapor contaminated with a damaging substance flows. The vapor pipe break detection device comprises a vapor pipe 1 through which vapor flows, a detection pipe 2 provided so as to surround the outer periphery of the vapor pipe 1, and a temperature detector 4 having a sensing unit 4a for detecting the presence or absence of blow-out vapor, the sensing unit 4a facing a vapor retaining space 3 between the outer peripheral surface of the pipe 1 and the inner peripheral surface of the detection pipe 2. If the vapor pipe 1 is damaged and vapor escapes from the damaged portion, even if the damage is minor, vapor enters the vapor retaining space 3 surrounded by the vapor pipe 1 and the detection pipe 2 outside the vapor pipe 1. The detection of the vapor by the temperature detector 4 makes it possible to identify damage at an early stage, allowing the vapor pipe 1 to be repaired while damage to the vapor pipe 1 is still minor. Accordingly, apparatuses provided downstream and upstream of the vapor pipe 1 do not have to be stopped, resulting in an increase in the rate of operation of equipment.
