The helical design has been used in a variety of applications to dampen flow-induced forces that can damage equipment. WIKA uses the same concept to stabilize thermowells and as an efficient and economical way to prevent thermowell mechanical fatigue and failure. One of WIKA\u2019s product experts explains it all in Flow Control <\/em>magazine.<\/strong><\/p>\n

The August 2018 issue of Flow Control\u00a0<\/em>features an article about how to protect thermowells from vortex-induced vibrations and mechanical fatigue. It was written by Adam DeLancey, WIKA Product Manager for Electric Temperature Measurement and a seasoned veteran on the topic of temperature measurement solutions.<\/p>\n

In his article, DeLancey explains how, under certain flow conditions, the fluid inside the pipeline can create vortices. These vortices produce periodic lift and drag forces around the thermowell that make it shake. If the frequency of these vibrations is close to the thermowell\u2019s natural frequency, the thermowell can \u201clock in\u201d and go into resonance. It is therefore very important that thermowells pass wake frequency calculations that take into account dynamic stresses.<\/p>\n

What to Do If the Thermowell Does Not Pass Wake Frequency Calculations?<\/h2>\n

Traditional methods for reducing thermowell vortex-induced vibrations include:<\/p>\n

    \n
  1. Shortening the insertion length<\/li>\n
  2. Increasing the root diameter<\/li>\n
  3. Increasing the tip diameter<\/li>\n
  4. Adding support collars<\/li>\n<\/ol>\n

    Many times, however, these adjustments do not reduce vibrations enough to allow thermowells to pass wake frequency calculations, or are very expensive and time-consuming to implement.<\/p>\n

    WIKA\u2019s Helical Thermowells: An Efficient, Affordable Solution<\/h2>\n

    Engineers have used helical strakes for decades to reduce vortex-induced vibrations in a variety of industrial applications, including on\/offshore risers and platforms, and cables in suspension bridges. WIKA applied this same concept to its ScrutonWell\u00ae<\/sup> design<\/a>. The result? An easy to install thermowell that reduces the amplitude of the vibrations by more than 90%. There\u2019s no need to change the dimensions of the thermowell or perform expensive and time-consuming retrofittings to pass wake frequency calculations.<\/p>\n

    The ScrutonWell\u00ae<\/sup> helical design can be used in all solid-machined thermowells and with a variety of process connections. This type of thermowell works particularly well in petrochemical processes<\/a>, on\/offshore applications, and plant construction. It is also the recommended option for critical measuring points and high process loads where conventional thermowells are not suitable<\/p>\n

    In the article, DeLancey mentions one of the many real-life cases where the ScrutonWell\u00ae<\/span><\/sup><\/span> design proved to be an efficient and affordable solution. Thermowells in the crude units that a major oil company was updating were having problems with vortex-induced vibrations. Traditional methods were not enough to reduce the vibration. WIKA\u2019s ScrutonWell\u00ae<\/sup> design neatly solved the problem. Now the crude units not only pass wake frequency calculations, but they have room for future upgrades.<\/p>\n

    Thermowells are a fast and inexpensive solution for protecting temperature sensors in oil and gas processes and other industrial applications. Click here<\/a>to read DeLancey\u2019s article.
