Solutions in Action: Steam Valves

Steam Header / Distribution​

Steam mains, headers, and branches distribute steam throughout the plant to the equipment where its heat can be utilized.​

It is critical to keep the steam dry throughout the distribution lines to maintain safe operation and longevity of the piping, valves, and equipment. High velocity water droplets cause the erosion of pipe walls and valves, the presence of liquid water from condensation or boiler carryover leads to corrosion, and accumulated water can be propelled by high velocity steam causing water hammer damage.​

Many traditional stop valve technologies leak even when new. High velocity steam flowing past a leaking seat causes wire-draw, accelerating leakage and compromising the valve’s ability to seal when needed.​

Steam Conditioning​

Temperature is controlled in a variety of ways in a process plant environment. Process steam must be conditioned to a point near saturation where it is more efficient for heat transfer. Properly-selected equipment will ensure optimum plant availability, reliability, and profitability.​

The desuperheater valve injects a controlled amount of water into a steam flow to lower the temperature of the steam. To achieve this efficiently, the desuperheater must be designed and selected correctly for the application.​

Pressure Reduction Stations​

Pressure reduction stations are used to lower steam pressure to levels suitable for downstream equipment pressure ratings and for efficient heat transfer. Wet, high-velocity steam is erosive to valve internals which can jeopardize pressure-reducing valves’ ability to shut off.​

Steam passing through a pressure reducing valve at high flowrates and pressure drops generates significant noise and vibration due to turbulence. In addition to hearing safety concerns, noise travels to downstream equipment where it can cause vibration damage.​

Heat Exchangers / Reboilers​

Reliability is paramount in heat exchanger applications since a singleunplanned shutdown or slowdown can have a cascading effect ondownstream processes.​

In heat exchangers, steam transfers its latent heat to the process fluidand condenses. If not properly managed, condensate can accumulatewithin the heat exchanger leading to issues such as condensate stall,water hammer, reduced efficiency, and corrosion. ​

Variations in steam supply temperature or pressure can reduceefficiency or damage equipment so precise control of steam flow is critical.​
