Family Owned & Operated Since 1971• Bakersfield, CA
Specialty barstock thermowell with a patented twisted-square stem profile that dramatically reduces vortex-induced vibration. Designed for high-velocity service where a straight or tapered stem would resonate and fail by fatigue. ASME PTC 19.3 TW-2016 compliance for vortex-induced stress mitigation. Same 114C platform as the standard barstock thermowell, but with Threaded mounting only and the unique Twisted stem style (place #13 code T). Wide material selection: 316/316L SST, 304/304L SST, Carbon Steel A-105, 310 SST high-temp, 321 SST, Alloy B-3, Alloy C-276 (Hastelloy). Immersion length 2-40 in / 50-1000 mm.
Twisted Square supports 2-40 in / 50-1000 mm. Specify the exact length from the line schedule (custom lengths fall in ¼-in or 5 mm increments).
Twisted Square is Threaded-only. For flanged / Van-Stone / welded thermowells use the 114C standard barstock family.
Fixed: Twisted profile. This is the defining feature of the Twisted Square family — the twisted geometry suppresses vortex-shedding-induced vibration.
Rosemount is configurator-heavy and quote-only — Valley Instrument verifies option compatibility, lead time, and pricing before confirming your order.
