Selection of steam traps

Thread Content

1. Pressure: When selecting a steam trap, the inlet pressure is the first factor to consider. However, in practice, backpressure is often present; therefore, the key pressure parameter used for selection is the pressure difference. 2 Flow rate: After determining the operating pressure difference, the normal flow rate under that pressure difference is determined. A safety factor is usually taken into account in the design, and therefore the safe flow rate must be equal to the normal flow rate multiplied by this safety factor; the selection of the appropriate model is based primarily on this safe flow rate. 3 Temperature: The temperature should be normal, as long as it meets the required inlet temperature. 4 Materials: Materials are divided into the valve body material and the internal material; it is sufficient to meet the design requirements under normal circumstances. There is no need to choose a higher-grade material unless required by specific conditions. For 5 interfaces, the key considerations are the diameter and the connection method; the diameter should meet the traffic requirements, while the connection method is chosen according to the design specifications. The model selection mentioned here is the choice of a model based on the calculation and determination of various parameters.
