Thermowells serve as protective structures for temperature sensors like thermocouples, thermistors, and bimetal thermometers. They shield these sensors from potential harm caused by excessive pressure, material velocity, and corrosion. Additionally, thermowells enhance the lifespan of the sensors, enable easy replacement without system drainage, and minimize the risk of contamination. In high-pressure scenarios, thermowells are usually machined from bar stock to ensure their integrity. Conversely, smaller thermowells for low-pressure environments can be made from tubing, with one end welded shut.

There are various types of thermowells, including threaded, socket-weld, and flanged. Threaded thermowells have threads and are easy to install and remove, but are not suitable for high-pressure applications. Socket-weld thermowells are sturdier and more durable but more expensive, but only suitable for certain socket weld fittings. Flanged thermowells have flange collars connected to mating flanges and are strong but expensive. They are generally used in high-pressure applications where threaded or socket weld thermowells aren't suitable.
