What is the purpose of a pop test?

The purpose of a pop test is to determine if a safety valve opens at the proper pressure. Safety valves are critical components in a boiler system, designed to release excess pressure and prevent potential explosions or damage to the boiler. During a pop test, the valve is subjected to pressure to confirm that it opens at the specified set-point pressure, which is essential for ensuring safe operation. If the safety valve does not open at the correct pressure, it could lead to dangerous situations in the event of overpressure conditions. This test is a vital practice in maintaining the safety and integrity of the boiler system.
