Industrial borescopes are indeed commonly used to detect defects on the inner surface of copper pipes. A borescope is a flexible optical device that consists of a long, narrow tube with an eyepiece or a camera at one end and a lens at the other. The lens captures images or video of the internal surface of the pipe and allows inspectors or technicians to examine it without the need for disassembly.

In the case of copper pipes, borescopes are particularly useful for inspecting and identifying defects such as corrosion, scaling, blockages, cracks, or other irregularities that may occur on the inside walls. These defects can compromise the structural integrity and performance of the pipes, leading to leaks, reduced flow, or other issues.

When using a borescope to inspect copper pipes, the following steps are typically followed:

Preparation: Ensure the pipe is accessible and clean. Remove any obstructions or debris that may interfere with the inspection.

Insertion: Insert the borescope into the pipe through an entry point such as a valve or an access port. The flexible nature of the borescope allows it to navigate through the twists and turns of the pipe.

Visualization: Observe the images or video feed from the borescope either through an eyepiece or on a display screen. Some borescopes are equipped with built-in cameras that can capture high-resolution images or record videos for later analysis.

Inspection: Move the borescope along the length of the pipe, examining the internal surface for any defects or abnormalities. Pay close attention to areas prone to corrosion, joints, or bends where defects are more likely to occur.

Documentation: Take pictures or record videos of any identified defects for documentation and further analysis. This information can be useful for making informed decisions regarding repairs or maintenance.

Borescopes are valuable tools in industrial settings, including plumbing, HVAC (heating, ventilation, and air conditioning), automotive, and aerospace industries, where the internal condition of pipes or other components needs to be assessed without the need for disassembly.
