Description
Challenge
The customer needed to inspect the entire inside of their composite overwrapped pressure vessels (COPV), including their 1.09” diameter entry point. The inspection needed to detect any corrosion, debris, and/or staining on the entire inside of the COPVs. The inside was low-light so illumination was needed.
The challenge was to fit an entire HD camera with LED lights through a 1.09” entrance hole, and once inside, be able to articulate the camera to ensure 100% inspection of the entire inside surfaces of the COPVs.
Development
The customer provided a sample COPV to be used in proving the design. It was apparent that a wand-like inspection system was ideal for this application. The wand was test-fit for size as well as picture and illumination to ensure there was full visibility of the inside of the COPV. Initially, a forward-view angle camera was used, and it was found that a right-angle view was required to ensure 100% inspection coverage for the inside COPV. Also, it became apparent that after repeated inspections, the threaded neck of the COPV was going to slowly damage the articulating camera wand. An extra effort to make a neck fixture was needed.
Solution
The InterTest solution was an articulating camera wand that was test-fit for size integrated with an iShot Full HD 15mm Micro Camera System. This product was used in conjunction with the custom neck fixture to minimize damage attained by the threaded neck of the COPV. Video inspection showed that 100% of the inside of the COPV was visible.
