  • Design Guide: Steam Pressure Reduction Stations
  • Vent & Waste Steam Recovery
    In many Pulp & Paper, Steel Processing, and Refinery process, a considerable amount of steam is lost during blow down periods, shut downs, and normal operation. Often this steam pressure is in the 50 - 60 psig range. This vent steam can be reclaimed and used to heat water in the plant for energy
  • 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
  • Application Note: Oil & Gas - SAGD Steam Injection & Letdown Valves
    The majority of SAGD facilities will use once-through steam generators (OTSG) for their steam production. The steam from these OTSGs is piped to steam letdown valves, which drop the pressure to injection valves that inject the steam into the well pad. The steam pressures are quite high
  • 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
  • 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
  • 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.
  • 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
