重要な技術的利点
-
Imperial Standardization: Designed primarily according to ASME B40.9 norms, the TT152 is optimized for North American and international markets that utilize imperial pipe sizes and NPT threads.
-
iTHERM TwistWell Technology: This model can be configured with a helical (twisted) shaft design. This innovation suppresses vortex-induced vibrations (VIV) by breaking up the symmetry of vortex shedding behind the thermowell. This allows for longer immersion lengths in high-velocity flows where a standard tapered thermowell would fail mechanical safety calculations.
-
Extreme Pressure Resistance: Drilled from solid barstock, the TT152 handles process pressures up to 500 bar (7,252 psi), providing maximum safety for personnel and the environment in high-pressure steam or hydrocarbon applications.
-
Material Versatility: To ensure a long service life, the thermowell is available in a wide variety of materials, ranging from 316/316L stainless steel to exotic alloys like Monel or Hastelloy, which protect against aggressive chemical corrosion.
-
Optimized Maintenance: By using the TT152, the temperature sensor becomes an “insert” that can be removed for calibration or replacement without draining the pipe or shutting down the process, significantly lowering operational costs.
-
Customizable Geometry: The shaft, immersion length, and total length can be tailored to the specific hydraulics of the measuring point to ensure the sensor tip is perfectly positioned in the flow while maintaining structural integrity.
