How Do I Size and Select ASME Forged Pressure Valves?
Pressure vessel nozzle manufacturing is a very intricate and custom process depending on the size and use of the pressure vessel valve. There are many variables to consider when selecting size and pressure capacity. Pressure relief valves must be selected by those who have complete knowledge of the pressure relieving requirements of the system to be protected and the environmental conditions particular to that installation.
Too often pressure relief valve sizes are determined by merely matching the size of an existing available vessel nozzle, or the size of an existing pipe line connection. Correct and comprehensive pressure relief valve sizing is a complex multi-step process that should follow the following stepwise approach. Here are some of the most important factors to consider when sizing a ASME forge pressure valve.
- Each piece of custom pressure vessel connections equipment in a process should be evaluated for potential overpressure scenarios.
- An appropriate design basis must be established for each vessel and forged vessel component. Choosing a design basis requires assessing alternative scenarios to find the credible worst case scenario.
- The design basis is then used to calculate the required pressure relief valve size. If possible, the sizing calculations should use the most current methodologies incorporating such considerations as two phase flow and reaction heat sources.
In order to properly select and size a pressure relief valve, the following information should be ascertained or each vessel or group of vessels which may be isolated by control or other valves. The data required to perform pressure relief valve sizing calculations is quite extensive. That is why Forged Components, Inc. can help design your custom pressure vessel connections.
