Thermowells & Accessories
Thermowell is a tube, closed at one end, which protects the probe and allows its removal without breaking the liquid seal. Many materials and styles are available to match application requirements. Thermowells drilled from solid bar stock provide the highest pressure ratings, and welded models are also available.
In some cases helical strakes can be machined on the thermowell at the insertion length. These helical strakes obstruct the formation of vortices behind the thermowell which decreases the stresses caused due to vortex shedding. This style of design is usually found in Long Chimneys due to the presence of high velocity air currents on higher altitude. Similar concept can be implemented on to Thermowells.
