45. According to the International Fuel Gas Code
Answer: B
The maximum horizontal support spacing for 1-inch copper tubing is 4 feet.
The maximum horizontal support spacing for 1-inch copper tubing, as outlined in the International Fuel Gas Code, is set at 4 feet. This regulation ensures the structural integrity of the tubing and minimizes movement that could lead to damage.
A) what is the MAXIMUM horizontal support spacing for 1-inch copper tubing
This option does not provide a numerical answer, making it unhelpful in determining the correct spacing requirement. It merely states the question without offering the necessary information or context.
B) 4 feet
This option is correct as it directly states the maximum allowable horizontal support spacing for 1-inch copper tubing according to the International Fuel Gas Code. Maintaining this spacing is crucial for safety and functionality in gas piping systems.
C) 6 feet
While 6 feet may seem reasonable for certain applications, it does not comply with the International Fuel Gas Code requirements for 1-inch copper tubing. Exceeding the specified 4 feet could lead to increased risk of sagging and potential damage to the tubing.
D) 8 feet
An 8-foot spacing exceeds the maximum limit set by the International Fuel Gas Code for 1-inch copper tubing. This incorrect spacing could compromise the structural stability and safety of the installation, leading to potential hazards.
E) 10 feet
Ten feet is well beyond the allowable maximum support spacing for 1-inch copper tubing. Adhering to this spacing guideline is essential for ensuring proper support and preventing failures in the gas delivery system.
Conclusion
The correct answer of 4 feet is essential for ensuring the safe and effective installation of 1-inch copper tubing as per the International Fuel Gas Code. All other options either exceed this maximum spacing or fail to provide a specific answer, which does not meet the requirements set forth by safety regulations. Therefore, adhering to the 4-foot maximum is critical for maintaining system integrity.
