Abstract
Provided is a tube weld X-ray inspection device for inspecting an abnormality, such as a tube welding part crack, of a heat exchanger by using X-rays.
Claims11
A tube weld X-ray inspection device, comprising:
- an X-ray support configured to be inserted into a tube;
- an X-ray source provided at a side of the X-ray support in a length direction of the X-ray support, the X-ray source being configured to emit X-rays;
- image plate fixing part configured to fix an image plate in a direction parallel to an axis of the length direction of the X-ray support while being spaced a predetermined distance from the X-ray source;
- and
- a reader configured to irradiate the image plate with an irradiation light and receive a signal light diverging from the image plate to convert the signal light into information in a form of an image,
- wherein the image plate is configured to absorb the X-rays and store the X-rays in a form of energy, and
- wherein, as the image plate is rotated and the reader is fixed, or as the reader is rotated and the image plate is fixed, the reader obtains the information in the form of the image.

- a reader configured to irradiate the image plate with an irradiation light and receive a signal light diverging from the image plate to convert the signal light into information in a form of an image;
- and
- an initializer configured to irradiate the image plate with light to make the image plate be in a re-photographable state,
- wherein the image plate is configured to absorb the X-rays and store the X-rays in a form of energy, and
- wherein, as the image plate is rotated and the initializer is fixed, or as the initializer is rotated and the image plate is fixed, the initializer makes the image plate be in the re-photographable state.

- wherein the image plate is configured to absorb the X-rays and store the X-rays in a form of energy, and
- wherein the initializer moves to an outside of a region for the image plate before X-ray photography, and moves to a position at which the image plate is made to be in the re-photographable state, after the X-ray photography.
