TW-SDF

Stepdown Shank Thermowell with Flange

Stepdown shank thermowell combining the root strength of a straight shank with improved wake frequency characteristics of the reduced-diameter tip section. The step-reduction in diameter at the midpoint improves the natural frequency to process frequency ratio (fn/fs) to meet ASME PTC 19.3 TW requirements in moderate to high-velocity process streams. Used in steam, water, and hydrocarbon service pipelines.
