Final answer:
The minimum size hanger rods for pipes with a diameter of 10-12 inches typically range from 5/8" to 3/4", depending on factors like weight and material. It's essential to consult with the latest standards or a professional engineer for specific requirements.
Step-by-step explanation:
The minimum size of hanger rods for supporting pipe diameters of 10-12 inches is generally determined by several factors, including the weight of the pipe, the contents it will carry, and the material of the hanger rod.
However, a common practice according to building codes and industry standards (like those set by the American Society of Mechanical Engineers - ASME) is to use hanger rods not less than 3/8" in diameter. But for larger pipes, such as 10-12 inches in diameter, and heavier service, a hanger rod diameter of 5/8" to 3/4" may be required to ensure adequate support and safety.
To confirm the exact size for your specific application, it's essential to reference the latest engineering standards or building codes, or consult a professional engineer. This is necessary to accommodate for variances in weight, material, and environmental factors that could influence the necessary diameter of the hanger rod.
