Probe-Type Desuperheaters for 6 Inch and Larger Pipe

The LPD large pipe desuperheater is designed for steam pipes 6 inches and larger. Final application suitability depends on the steam conditions, required temperature reduction, flow requirements, installation arrangement, and pressure class. Application details should be reviewed with B-Tech Valve before equipment selection.

The LPD uses a 90° flanged insertion on the steam pipe. This installation method positions the probe within the line while providing a flanged connection for equipment integration. Piping arrangement, access, control requirements, and operating conditions should be confirmed during application engineering.

The product information identifies ASME B16.34 pressure classes 150, 300, 600, 900, 1500, 2500, and 2700. The appropriate class is selected according to the steam system design and operating requirements. Buyers should provide line conditions and connection details for application review.

The LPD is temperature rated up to 1,200°F (650°C). Actual suitability depends on the complete operating envelope, including steam temperature, pressure, flow, spray-water conditions, and control requirements. B-Tech Valve can review these details to help determine an appropriate configuration.

Applications include increasing steam heat-transfer capability, protecting piping and steam traps, protecting rotating seals, increasing steam flow, decreasing boiler loads, and reducing fuel costs. The product is identified for power plants and process plants with large steam piping and high-temperature steam systems.

Selection typically requires pipe size, steam pressure and temperature, steam flow, desired outlet conditions, spray-water details, pressure class, connection requirements, and control information. Providing complete operating data helps determine whether the variable-nozzle probe design and 90° flanged insertion are suitable for the installation.
