What is the recommended distance between hangers for a 12" pipe in a steam system?

In high pressure piping systems, especially for steam lines, proper support and spacing between hangers is crucial for the integrity and safety of the piping installation. For a 12-inch diameter pipe, the recommended distance between hangers is 30 feet. This spacing helps to prevent sagging and minimizes the risk of excessive stress being placed on the pipe due to temperature changes, thermal expansion, and weight.

When considering factors such as pipe material, fluid type, and temperature fluctuations, a spacing of 30 feet aligns with industry standards for accommodating these conditions. It ensures that the thermal and mechanical stresses on the pipe are effectively managed, maintaining the structural integrity and efficiency of the steam system.

Using closer spacing could lead to unnecessary costs and installation complexity, while greater spacing might not provide adequate support, risking pipe damage and system failures. Therefore, adhering to the 30-foot standard is both practical and aligned with best engineering practices for high-pressure steam piping systems.
