Answer :
The recommended maximum unsupported vertical run for a 22mm copper gas pipe is 'b) 2.0m'.
In engineering, specifically plumbing and gas installation, the support of pipes is critical for safety and functionality. The length of a pipe that can run without support is determined by its material and diameter. For copper gas pipes, which are commonly used due to their durability and flexibility, it is essential to adhere to standards to prevent any potential risks, such as sagging or damage that could cause leaks.
Understanding this safety measure involves knowing how gas lines are secured properly with pipe supports, like hangers, brackets, or clamps, to ensure they do not move or sag over time. Regular checks and maintenance are also crucial for ensuring long-term safety in gas piping installations.
Therefore, based on established plumbing standards and best practices, a 22mm copper gas pipe should not exceed an unsupported vertical run of 2.0 meters to ensure its structural integrity and safety.
