Desuperheaters for 8 to 24 Inch Steam Lines

This category covers Desuperheaters for 8 to 24 Inch Steam Lines. The featured LPD Large Pipe Desuperheater is identified for pipe sizing of 6 inches and larger, making it applicable to the stated line-size range. Final selection should be based on the complete steam application, operating conditions, and required desuperheating performance.

The LPD combines a probe-type variable nozzle and fully actuated control valve with a desuperheater assembly. It is installed through a 90° flanged insertion on the steam pipe. This arrangement allows controlled water injection into large steam lines while integrating the control valve and desuperheater into one assembly.

The LPD uses flanged insertion at 90° on the steam pipe. Installation planning should account for the pipe configuration, available access, connection requirements, operating conditions, and the application-specific information needed to confirm the correct equipment arrangement.

The LPD is available in ASME B16.34 pressure classes 150, 300, 600, 900, 1500, 2500, and 2700. The appropriate pressure class should be selected from the steam system design conditions and project requirements. B-Tech Valve can provide application information for evaluation and quotation.

The LPD is temperature rated up to 1200°F (650°C). Actual selection and operation must consider the complete steam application, including operating temperature, pressure, flow conditions, materials, and control requirements. Application review is recommended before specifying the equipment for a particular steam line.

Large-pipe desuperheaters are used in power plants and process plants where superheated steam requires conditioning. Applications include improving steam heat transfer, protecting piping and steam traps, protecting rotating seals, increasing steam flow, decreasing boiler loads, and reducing fuel costs within the steam system.
