High pressure gas diffuser

Product overview
The Two-Stage Dump Tube from IMI CCI is engineered to reduce noise during steam discharge into condensers, especially in turbine bypass applications with high pressure drops. Its multi-stage, fixed-orifice design splits the pressure drop across two stages to lower acoustic emissions and protect downstream equipment. Custom-designed for each installation, the dump tube ensures precise steam temperature control, optimises sizing of bypass valve and tube, and is welded directly to the downstream steam pipe. Constructed from alloy steel (optional stainless steel), it is suitable for water- or air-cooled condensers and integrates with control systems for thermal power plant solutions.

Benefits

• Reduces noise levels by splitting pressure drop across two stages in high-pressure steam applications.
• Minimises risk to condenser and turbine internals by directing flow and controlling steam temperature.
• Lowers installation cost through optimised valve and tube sizing and reduced piping requirements.
