Steamfitter Safety Practice Exam 2025 - Free Steamfitter Safety Practice Questions and Study Guide

The safe working pressure limit for steam pipes in most industrial settings typically falls within the range of 10 to 150 psi. This range is widely accepted as it provides a balance between operational efficiency and safety protocols. Below this threshold, the risks of leaks, bursts, and other pressure-related failures are significantly reduced, making it a standard for steam systems designed for moderate pressure applications.

Steam systems are meticulously designed to handle specific pressure ranges, which also comply with safety codes and standards. Operating steam pipes above this range may demand additional safety measures such as reinforced materials, specialized fittings, and rigorous testing procedures to manage the increased risk associated with higher pressures. Therefore, while options indicating pressures above 150 psi may be relevant in specific industrial applications, they are not the standard safe working limits for general steam piping.
