What hanger size is required for use with a 6 inch outside diameter pipe covered with 1 inch thick insulation?

To determine the correct hanger size for a 6-inch outside diameter pipe with 1 inch thick insulation, it is critical to consider the overall diameter of the pipe after insulation is added.

The pipe has an outside diameter of 6 inches. Adding 1 inch of insulation to the pipe increases its overall diameter. Therefore, the calculation for the total diameter is as follows:

• 6 inches (pipe diameter) + 1 inch (insulation) + 1 inch (insulation on the opposite side) = 8 inches.

As a result, the overall diameter of the insulated pipe is 8 inches. The appropriate hanger size needs to accommodate this total diameter to ensure a secure fit.

Given that a hanger is typically selected based on the overall diameter of the pipe with insulation, a hanger that is 9 inches in size is necessary to allow for proper clearance and fitting around the insulated pipe. This extra space ensures that the hanger can safely secure the pipe without causing any undue pressure or damage to the insulation or pipe itself.

Choosing a hanger that is too small could result in strain on the pipe, whereas a hanger that allows for a bit more space, such as a 9-inch one, ensures a better fit and allows
