A thermowell is a protection for the temperature sensors in the form of cylindrical shaped pressure-tight fittings. It is used to protect the temperature sensors which are inserted into vessels and pipes for being used in different industrial applications. It is used to create a barrier between the process media and sensing element as the process media can be corrosive and can negatively impact the sensing element. Moreover, it protects the sensing elements from fluid velocity and pressure. Thermowell Types: 1. Threaded Thermowell They are usually used in smaller pipes where the temperature of the non-corrosive fluid is measured. Threaded thermowell is screwed in the pipe for use and generally does not require replacements. 2. Flanges Weld Thermowell As the name suggests, flanged thermowell is flanged at the top end. It is connected to the pipe using nuts and bolts. It is mostly used in applications that require frequent replacements and involve high temperatures. 3. Socket Weld The
