Question: 1 / 400

What is the minimum pipe insulation thickness in inches for a steam pipe greater than 1.5 inches in diameter?

2 inches

2.5 inches

3 inches

The correct answer indicates that the minimum pipe insulation thickness for a steam pipe greater than 1.5 inches in diameter is 3 inches. This requirement is typically based on the need to effectively minimize heat loss and prevent condensation on steam pipes, which can lead to inefficiencies and potential damage over time.

Insulating steam pipes significantly reduces heat transfer to the surrounding environment, resulting in better energy efficiency. For larger diameter pipes, the required insulation thickness tends to increase to ensure that sufficient energy conservation is achieved. Therefore, 3 inches of insulation is established as the standard minimum thickness for pipes of this size to maintain operational efficiency and safety.

Understanding these requirements helps contractors adhere to building codes and performance standards, ensuring the longevity and efficacy of the installed systems.
