What must be avoided when piping relief valves with steel?

When piping relief valves with steel, it is essential to avoid using threads on the open end because this can compromise the safety and functionality of the system. The open end of a pipe connected to a relief valve is critical because it is where the relief valve discharges excess pressure or fluid. If threads are present on this open end, there is a risk of leakage, which can lead to improper operation of the relief valve and may fail to relieve excess pressure. This situation can create hazardous conditions, as the relief valve is designed to prevent pressure buildup that could damage equipment or cause dangerous situations.

In addition, threads may create points of weakness, increasing the likelihood of mechanical failure or failure to seal correctly. Additionally, smooth edges and a proper pipe fitting are vital for ensuring that the flow of fluids is uninterrupted and effective, contributing to overall system safety and performance.
