A flanged thermowell is a crucial component used in various industrial applications to protect temperature sensors, such as thermocouples and RTDs, from extreme environments while allowing accurate temperature measurements. This device consists of a tube closed at one end and mounted to a flange, which is then bolted to a pipe or vessel, providing a secure and durable installation. The design of the flanged thermowell shields the sensor from physical impact, corrosive fluids, high pressure, and flow-induced vibrations, thus extending the sensor's lifespan and maintaining the integrity of measurement data. Commonly used in chemical processing, oil and gas, and power generation industries, flanged thermowells are indispensable for ensuring safe, efficient, and continuous operations in demanding conditions.
