摘要: A pipe expansion method capable of reducing an inspection range (area) of a heat-transfer pipe secured to a pipe plate and capable of shortening the time required for inspection is provided. In a pipe expansion method for securing a heat-transfer pipe (13) inserted in a pipe hole (3a) of a pipe plate (3) by expanding the pipe, after tightly fitting an outer circumferential surface of the heat-transfer pipe (13) to an inner circumferential surface of the pipe hole (3a) from a primary-side end face to a secondary-side end face of the pipe plate (3), surface pressure between the heat-transfer pipe (13) and the pipe plate (3) is further increased in a predetermined range from the secondary-side end face, or close to the secondary-side end face, towards the primary-side end face.

摘要: There is provided a method for measuring a contact force applied to each tube constituting a tube bundle disposed in a fluid from a vibration damping member by using a probe inserted into each tube. Characteristic data defining a relationship between a value measured by the probe and the contact force is previously prepared. Then, the probe is inserted into the tube, and the contact force is calculated using the measurement value of the probe, based on the characteristic data.
