  • Steam Ratings for Ball Valves
    RuB ball valve styles which use teflon stem seals (s.40, 42, 70, and 92) are rated at 150 psi WSP (Working Steam Pressure). But our valve styles which have FPM (like DuPont Viton (R)) stem seals (the s64 or s95 for example) cannot be consistently satisfactory at 150 WSP without some restrictions
  • Protecting the Pressure Transmitter
    Measuring steam pressure is a common application in the HVAC industry, but finding a transmitter that can handle the higher temperatures of steam can be a challenge. Steam, under typical HVAC and process pressures, may reach temperatures ranging from 212°F to 400°F, but most pressure transmitters
  • Steam Ejector Pumps And Ejectors & Steam Ejector Theory
    Steam ejectors are designed to convert the pressure energy of a motivating fluid to velocity energy to entrain suction fluid and then to recompress the mixed fluids by converting velocity energy back into pressure energy. This is based on the theory that a properly designed nozzle followed
  • Providing Steam Isolation & Temperature Protection
    All pressure transducers installed on steam lines should be isolated from the steam to protect them from damage. A steam pigtail syphon (such as the MODEL PT) may be used for this purpose.
  • Boiler Steam System Supply Basics
    The boiler is part of a cohesive system, just like the human body with the heart (boiler) pumping blood through a venous system consisting of arteries (steam supply) and veins (condensate return). The piping should be considered an extension of the boiler because if it ruptures, it's an unfired
  • Forced-Circulation Steam Generators for SAGD Applications
    a pair of horizontal wells drilled into a reservoir. In the SAGD process, one well is drilled above the bitumen deposit and a second one below the deposit. The. upper well is supplied with high-pressure steam, and the lower well collects the heated oil or bitumen that flows. out, along with any
  • Condition Monitoring of Steam Turbines by Performance Analysis
    is extracted from the steam. This also results from internal leakage within a casing which allows steam to bypass blading stages. These effects are particularly evident on the turbine design with both High Pressure and Intermediate Pressure sections in the one casing, with flow in opposite directions
  • Panel Mountable Pressure Transducers
    Pressure transducers form a critical function in today's closed loop systems providing data for safety, control and alarm functions encountered in typical industrial applications such as heating boilers, HVAC/R, gas correctors, compressors, test stands, fire suppression equipment and power
