Pressure Test Procedures - Stanford University

pressure test is required for a new pressure system before use or an existing pressure system after repair or alteration. There are two methods for pressure tests: hydrostatic and pneumatic. A hydrostatic test is performed by using water as the test medium, whereas a pneumatic test uses air, nitrogen, or any non-flammable and non-toxic gas.

BN-EG-K4 Standard Method for Safety Relief Valve Calculations

To do so, we divide the BTU/hour by a constant of 33,475. This constant represents water being converted to steam, which is 34.5 pounds of water multiplied by 970.3 BTU/lb, or latent energy. For this calculation, you will enter the BTU/hr of your operation along with the efficiency of your boiler.

Safety Valve Sizing | Spirax Sarco

The supply pressure of this system (Figure 9.4.2) is limited by an upstream safety valve with a set pressure of 11.6 bar g. The fault flow through the PRV can be determined using the steam mass flow equation (Equation 3.21.2): In this example: Consequently, the safety valve would be sized to pass at least 953 kg/h when set at 4 bar g.

How To: Determine The Maximum Allowable Working Pressure

With the boiler pressure at a minimum of 75% of the safety valve set pressure, the safety valve try lever is lifted to wide open position. Steam is discharged for 5 sec to 10 sec. The try lever is released, and the disk should snap to the closed position against the valve seat. Malfunctioning safety valves must be replaced as soon as possible.

2. BOILERS - Bureau of Energy Efficiency

A boiler is an enclosed vessel that provides a means for combustion heat to be transferred into water until it becomes heated water or steam. The hot water or steam under pressure is then usable for transferring the heat to a process. Water is a useful and cheap medium for transferring heat to a process.
