It is conceivable to employ a structure that is immersed in water. However, such a configuration is large and requires a strong waterproof structure, so that the maintainability is reduced, the cost is increased, and it is not practical.

- the flow rate of the contact medium W discharged from the contact medium discharge port 212 is about 10 to 15% of the supplied flow rate, which is less than 1 liter / minute. This is because if the flow rate of the contact medium W is less than 2 liters / minute, it is difficult to form the film W2 formed by the contact medium W rising above the upper surface of the spacer 23 due to the insufficient flow rate. Further, if the flow rate of the contact medium W exceeds 6 liters / minute, the possibility that the contact medium film W2 rising above the upper surface of the spacer 23 is disturbed due to excessive flow rate is increased.

- the excellent wear resistance is useful for preventing the folded portion of the bellows portion 22 from being damaged due to repeated expansion and contraction of the bellows portion 22.
- the excellent stretchability is useful for preventing the film W2 from being disturbed by the impact caused by the contact between the pipe P and the spacer 23 being directly transmitted to the film W2 of the contact medium.
- As a material for forming the bellows portion 22 it is preferable to use silicon rubber in view of excellent wear resistance and stretchability.
- the spacer 23 of the present embodiment is attached to the upper side of the bellows portion 22, and at least the upper surface (the lower surface in the present embodiment) is a flat horizontal surface. Further, the cylindrical member 24 of the present embodiment is attached to the lower surface of the spacer 23 and is fitted inside the bellows portion 22. Specifically, the outer diameter of the cylindrical member 24 is approximately the same (same or slightly smaller) than the innermost diameter of the bellows portion 22 so that the cylindrical member 24 is fitted inside the bellows portion 22. .

For this reason, even if the spacer 23 and the bellows portion 22 are not directly fixed, the spacer 23 is attached to the bellows portion 22 through the tubular member 24 in a relatively stable state.
- FIG. 4 is a front sectional view for explaining the operation of the tubular member 24 of the present embodiment.
- the left side of the alternate long and short dash line C indicates a state where the cylindrical member 24 is not provided
- the right side of the alternate long and short dash line C indicates a state where the cylindrical member 24 is provided.
- the contact medium retention part 2 of the present embodiment includes a cylindrical member 24, so that the bubbles B in the contact medium W do not reach the folded part 221 of the bellows part 22, and the cylinder It becomes easy to rise along the inner surface of the member 24.

This is because there is a high possibility that the contact medium film W2 will be disturbed. However, if the inner diameter Ds of the spacer 23 is too large, the size of the probe holder (contact medium retaining portion) 2 also increases accordingly, so that the probe holder including the weight of the contact medium W staying inside is increased. There is a possibility that the weight of the whole 2 increases and the follow-up performance of the probe holder 2 is lowered. Therefore, care must be taken not to set the inner diameter Ds of the spacer 23 too large.

For this reason, even if the pipe P is bent or the cross section of the pipe P is not a perfect circle, the contact medium film W2 is always in contact with the end of the pipe P and is prevented from being disturbed. Therefore, the contact medium W (including the film W2) is stably interposed between the end portion of the tube P and the ultrasonic probe 1. As a result, accurate ultrasonic flaw detection is possible.

Abstract
Description
斯かる方法によれば、管Pと超音波探触子1との間に接触媒質としての水Wを安定して介在させることができるため、精度の良い超音波探傷が可能である。
管端部を超音波探傷するための超音波探触子を水平方向に配置された管の上方に配置する場合には、例えば、超音波探触子と管端部との間に接触媒質を垂れ流す構造を採用することが考えられる。しかしながら、超音波探触子を管の下方に配置する場合に同様の構造を採用することはできない。管端部を超音波探傷するための超音波探触子を管の下方に配置する場合には、例えば、図1に示すような水槽を用いると共に、管の支持構造や追従装置を水槽内の水に浸漬させる構成を採用することが考えられる。しかしながら、このような構成は、大がかりになる上、堅固な防水構造が必要であるため、メンテナンス性が低下したり、コストが嵩み、実用的ではない。
ここで、環状のスペーサは、少なくとも上面が平坦な水平面とされているため、接触媒質滞留部本体に供給する接触媒質の流量を適切に調整することにより、接触媒質の表面張力によって接触媒質がスペーサの上面を超えて盛り上がった膜が形成される。この接触媒質の膜が管端部に接触することにより、超音波探触子から送信された超音波は、接触媒質滞留部本体内部の接触媒質、蛇腹部内部の接触媒質、及び前記膜を介して管端部に入射する。管端部で反射した超音波は、前記膜、蛇腹部内部の接触媒質、及び接触媒質滞留部本体内部の接触媒質を介して超音波探触子で受信される。
探触子ホルダーは、周方向に回転する管に追従する(上下方向及び水平方向についての管との位置関係を一定に保つように制御される)。さらに、蛇腹部は上下方向に伸縮する。このため、管に曲がりが生じていたり、管の断面が真円でなかったとしても、接触媒質の膜は、常に管端部に接触し、且つ、乱れることが抑制されるため、管端部と超音波探触子との間に接触媒質が安定して介在することになる。これにより、精度の良い超音波探傷が可能となる。
図2は、本発明の一実施形態に係る超音波探傷装置の正面視断面図を示す。図3は、図2に示す超音波探傷装置の平面図を示す。
図2又は図3に示すように、本実施形態に係る超音波探傷装置100は、水平方向に配置された管Pの端部の下方に対向配置され、管Pの端部に向けて超音波を送受信する超音波探触子1と、管Pの端部の下方に対向配置され、超音波探触子1が収納されると共に、周方向に回転する管Pに追従する探触子ホルダー2とを備える。
(1)管Pの外径:168mm
(2)管Pの回転速度:113rpm
(3)探触子ホルダー2の管軸方向への移動速度:15.1mm/sec
