Product Details

Mazda’s Dump Tubes are precision-engineered components that optimize the discharge of steam into condensers or turbine exhausts during bypass operations, start-ups, or sudden load variations. They provide the final stage of pressure reduction, allowing steam to expand and cool before entering the condenser. By reducing the size and requirements of turbine bypass valves and associated piping, Dump Tubes deliver both technical and cost-saving advantages. Each unit is tailor-made to meet installation requirements, ensuring compatibility, reliability, and long service life under demanding operating conditions.

Advantages

  • Minimizes bypass valve outlet size, lowering system cost
  • Reduces pipe size and overall installation footprint
  • Prevents interference with turbine exhaust steam path
  • Designed to minimize noise and avoid steam impingement on condenser tubes
  • Available in single or double tube configurations
  • Built with alloy steel, carbon steel, or stainless steel as per application needs performance.
  • Optional versions with integral spray water devices for temperature control

Brochure

Dump Tubes are fitted into the condenser inlet duct or turbine exhaust, where they act as the final stage of steam pressure reduction. Strategically drilled holes in the tube direct steam flow either across 90° sectors (in condenser installations) or 360° around the circumference (in turbine exhaust installations). This controlled expansion prevents turbulence, reduces noise, and ensures uniform steam distribution. In air-cooled or water-cooled applications, spray water devices can be integrated for precise steam temperature management using automated control algorithms.
