Boroscopy for Inspection of Piping Interior Surfaces and Weld Joints

Boroscope / Videoscope is an instrument or device which is used in the review and inspection of piping interior surface and weld joints of the pipes. It is the contemporary practice of pharmaceutical industry to use boroscope for documentation of orbital welding joints for inspection and review purposes. It is accomplished through small holes a few millimetres in diameter by means of a special Orientale probe, which transmits images directly to an LCD / LED monitor and can obtain in video as well as still images based on the specific requirements of the client.

The general objectives of Boroscopy/Videoscopy are:

• To examine and study the form of internal surface of pressure parts.
• To determine the occurrence of internal defects including corrosion, pitting or presence of foreign objects such as dust agglomerates, welding/grinding chips, crack
• To determine the amount of erosion, other extraneous problems in the locations for examination.

To take the photographs of pipe weld joints made by fusion of base material without the addition of filler and recorded in the attached external drive. It should meet the required specifications mentioned below:

• Uniformity in weld joints.
• Should have proper penetration.
• Should not have any foreign objects or pit material.

Procedure

1. The weld joints to be examined shall be made accessible for entry and movement of the fiber optic cable.

2. Synchronies the visual display with the camera tips vision for clarity.

3. Articulate the camera tip all around the seam and interrelate the joints quality.

4. The image shall be saved with the identification of the weld joints No. in appropriate folder memory card.

5. In case of rejection, the weld joint shall be marked with a specified procedure of rejection.

6. The rejection joint shall be carried for the rectification and re-offered..

7. Observation should be filled in Boroscopy Observation Sheet.
