What is the maximum length of gas piping supports for 1/2 inch copper tubing?

• A. 6 feet
• B. 8 feet
• C. 10 feet
• D. 4 feet

Answer: (D)

The maximum length of gas piping supports for 1/2 inch copper tubing is specified to be 4 feet. This requirement is based on safety and structural integrity standards for gas systems. Supporting piping at shorter intervals prevents sagging and minimizes the risk of mechanical stress or damage that could lead to leaks or failure over time. By ensuring that 1/2 inch copper tubing is supported every 4 feet, you create a more reliable installation that adheres to industry guidelines and reduces the potential for issues associated with unsupported or excessively long spans. Proper support helps maintain the alignment and stability of the gas line, contributing to overall system safety and efficiency.
