Title: PIPE REINFORCEMENT DEVICE AND PIPE REINFORCEMENT METHOD
Abstract:
[Solution] A pipe reinforcement device that extends the creep fatigue life of a cylindrical pipe for passing steam obtained by heating water using combustion heat of a boiler is provided with: a first reinforcement member which has a shape that makes surface contact with the outer peripheral surface of one half of the circumference of the pipe and which becomes thinner towards both ends in the direction along the longitudinal direction of the pipe; a second reinforcement member which has a shape that makes surface contact with the outer peripheral surface of the other half of the circumference of the pipe and which becomes thinner towards both ends in the direction along the longitudinal direction of the pipe; and a bonding member which bonds the first reinforcement member and the second reinforcement member with the pipe held therebetween.
