Socket Weld Thermowells are specialized components used in temperature measurement applications. They are designed to protect temperature sensors, such as thermocouples or RTDs (resistance temperature detectors), from the process fluid or gas being measured. Socket weld thermowell is typically used in high-pressure and high-velocity applications where the process fluid can be corrosive or abrasive. Socket weld thermowell consists of a hollow tube that is inserted into the process stream and welded onto a piping system via a socket weld connection.
