HEAT EXCHANGER QUALITY INSPECTION METHOD

PROBLEM TO BE SOLVED: To provide a heat exchanger quality inspection method capable of easily, appropriately inspecting the strength of a heat exchanger.SOLUTION: When the strength of a heat exchanger that comprises a plurality of heat transfer tubes provided therein and circulating a first fluid and a shell provided therein and surrounding the heat transfer tubes, that supplies and discharges a second fluid to and from a space between the heat transfer tubes and the shell, and that implements heat exchange between the first fluid and the second fluid is inspected, an inspection fluid G is fed from a pressure supply device 4 to the space between the heat transfer tubes and the shell to apply a pressure to the space and noise generated to accompany damage to the heat exchanger 2 is detected using an acoustic wave sensor 5.SELECTED DRAWING: Figure 1 【課題】熱交換器の強度を簡便且つ好適に検査し得る熱交換器の品質検査方法を提供を提供する。【解決手段】内部に第一流体を流通させる複数の伝熱チューブと、該複数の伝熱チューブを包囲するシェルとを備えてなり、前記伝熱チューブと前記シェルの間の空間に第二流体を給排させ、前記第一流体と前記第二流体との間で熱交換を行う熱交換器の強度を検査するにあたり、前記伝熱チューブと前記シェルの間の空間に対し、圧力供給装置４から検査用流体Ｇを送り込んで圧力を加え、熱交換器２の破損に伴う異音を音波センサ５を用いて検出する。【選択図】図１
