Safety valve discharge can produce noise levels up to 130dB(A) – well above the 85dB(A) occupational limit. A silencer (muffler) is effective, but the wrong type increases backpressure and affects valve performance. [2026-06-15]
When a safety valve pops, the high‑velocity discharge creates a huge reaction force. If not considered in design, it can bend discharge pipes, tear supports, or leak flanges. Three points are often missed. [2026-06-12]
When sizing a safety valve, most focus only on set pressure, ignoring accumulation pressure – the pressure rise above set pressure during discharge. If no margin is left, relief capacity may be insufficient, and pressur [2026-06-10]
Many plants stop at “annual calibration”. After testing, they reinstall the valve and forget it. But the period between calibrations is when most failures occur. The following four maintenance steps are often missed. [2026-06-08]
