Desuperheaters for 6 Inch Steam Pipe

B-Tech Valve offers the LPD Large Pipe Desuperheater for 6 inch and larger pipe, using a probe-type variable-nozzle fully actuated control valve with flanged insertion at 90 degrees. The Steam Attemperator uses a fixed-nozzle spray-ring design that clamps between steam pipe flanges and receives water from a separate temperature control valve.

Yes. The product information identifies power plants as an application for both the Steam Attemperator and LPD Large Pipe Desuperheater. They can support steam attemperation, equipment protection, heat-transfer capability and boiler-load reduction in power-generation steam systems.

Yes. Process plants are listed applications for both product designs. Desuperheaters can condition superheated steam for process use, help protect piping and steam traps, protect rotating seals and support steam heat-transfer requirements. Final selection should reflect the application, pipe configuration and operating conditions.

The listed products are available in ASME B16.34 pressure classes 150, 300, 600, 900, 1500, 2500 and 2700. The appropriate class depends on the steam system design and operating requirements. B-Tech Valve can discuss the relevant pressure-class selection during application review.

The product information states a temperature rating up to 1200°F (650°C) for both listed designs. The actual application should be reviewed against the selected design, steam conditions, pressure class and control arrangement before specifying a unit.

The LPD Large Pipe Desuperheater is installed through a flanged insertion at 90 degrees on the steam pipe. It is designed for 6 inch and larger pipe and combines a probe-type variable-nozzle actuated control valve with desuperheater functionality in one assembly.
