Question of the day

T or F Miters allowed in the systems having a design pressure greater than 50 psig

Explanation:
When a piping system is designed to handle more than 50 psig, the joints must maintain a very high level of mechanical integrity. A miter joint is formed by cutting pipe ends at an angle and welding them together to imitate an elbow. This creates a less uniform interior, more weld seams, and potential stress concentration at the joint. Under higher pressures, these weaknesses can lead to leaks or cracks, especially with vibration or temperature changes. For that reason, codes and best practices require using true elbows or other pressure-rated fittings with smooth interiors and appropriate radii that distribute stress more evenly. So, miters are not permitted in systems designed for pressures above 50 psig.
