Thermowells
Thermowells are tubular fittings used to protect temperature sensors installed in industrial processes. A thermowell consists of a tube closed at one end and mounted in the process stream. A temperature sensor such as a thermometer, thermocouple or resistance temperature detector is inserted in the open end of the tube, which is usually in the open air outside the process piping or vessel and any thermal insulation. The process fluid transfers heat to the thermowell wall, which in turn transfer heat to the sensor. Since more mass is present, the sensor’s response to process temperature changes is delayed. If the sensor fails, it can be easily replaced without draining the vessel or piping. To be representative of the average temperature of fluid, the thermowell must extend a few per cent of the inside diameter of the process pipe or vessel.
Drilled from our gun-drill machines, our thermowells enjoy a long lifespan are capable of functioning perfectly under critical conditions such as highly corrosive gases or liquids at high Temperature, high pressures, heavy vibrations, extreme shocks or high flow velocities. In order to offer the best and safest Thermowells against Karman’s Turbulence and other stresses, automatic calculations of mechanical strength to fluid and pressure and flow velocity to estimate frequency of critical resonance are made by a specially developed computer programme as based upon operation conditions at site.
Our Thermowells are also available for all conditions and applications, be it flanged-type, screwed type, welded type or van-stone type. Thermowells can also be custom-made from a huge variety of materials like stainless steel, Nickel Alloys, Titanium or many other materials to suit the unique needs of the industrial clients.
