What is the weight of 1.5" Schedule 80 pipe?

The weight of 1.5" Schedule 80 pipe is indeed 3.6 pounds per linear foot. This specific weight is determined by its dimensions and the material it is made from. Schedule 80 pipe has thicker walls compared to Schedule 40, which increases its weight without significantly altering its outer diameter. The thickness of the walls is what primarily contributes to the increased weight, making it more suitable for high-pressure applications.

When selecting pipe for rigging or any structural purposes in theatre, knowing the weight is crucial for ensuring that load limits are observed and that the rigging system is properly designed to accommodate the total weight without compromising safety. This understanding is also vital when considering the lift capabilities of rigging equipment and calculating the overall weight load that will be applied to the rigging system.
