Oct 22, 2020 · The ScrutonWell® thermowell was then designed in the same way. The natural frequency of the standard TW10-F thermowell was calculated as 38.7 Hz, in other words it deviated by only 4.1% from the frequency determined at the NEL by means of experiments. Flow-induced Vibration Failure of ThermowellsJan 31, 2019 · Flow-induced vibration can lead to fatigue failures of thermowells. Such failures typically occur at the base of the thermowell stem where it attaches to the mounting flange (photo).
New thermowell design prevents vibration. Klingenberg, April 2015. For applications in processes with high flow rates, WIKA is now offering thermowells in the new ScrutonWell® design. This variant is damping the excitation that leads to vibrations, which in turn can cause failures. The ScrutonWell® design is applicable to all solid-machined Operating Instruction for the Thermowell Calculation Thermowells manufactured from pipe, a designed surface structure of the shank (flame sprayed or weld overlays or stepped bore design) or thermowells with support collars or other means of support are outside of the scope of the standard. ScrutonWell Thermowells - WIKAThe ScrutonWell® design can be used for all kind of solid-machined thermowells with flange connection, in Vanstone design or for weld-in or threaded process connection. This helical design has been used successfully for decades in a wide variety of industrial applications to effectively suppress vortex-induced vibration excitation.
ScrutonWell design Thermowells with specially designed surface structures (e.g., a knurled surface or a surface with spiral ridges) are beyound the scope of this Standard, due to the difficulty of providing design rules with board applicability for these types of thermowells. 35 TW10:Thermowell solid machined with flange Thermowells data sheets - WIKA CanadaTW70. A datasheet about thermowells within the TW70 series are primarily designed for low pressure applications but also include high temperature, corrosion, and erosion services. Wish list. PDF. TW70.

thermowells with flange connection, in Vanstone design or for weld-in or screwed process connection. This design reduces the amplitude of oscillation by more than 90 % 1) and allows an easy and fast installation of the thermowell without expensive and time-consuming rework on site, at the same time. The WIKA ScrutonWell® design has beenThermowell in ScrutonWell design - jwfltdThermowell in ScrutonWell® design The helical coils, arranged around the thermowell stem of the ScrutonWell® design, break up the flow and thus impede the formation of a clearly defined Kármán vortex street. Through the reduced amplitudes of the diffused vortices, vibrational excitation of the thermowell is
