What are thermowells made of?
What are thermowells made of? Well, that depends on the application!
For many applications stainless steel is the most cost effective and suitable material, however for corrosive or erosive environments more resistant materials are more cost effective.
The issue with thermowells made from inadequately specified materials in a harsh environment is that they quickly fail to protect the temperature sensor inside, leading to wrong or no temperature measurement. Replacing the sensor and the thermowell requires the plant, such as a boiler, to be shut down, leading to loss of production/uptime.
Our manufacturing partners for high performance thermowells, BKW Instruments, were in the process of turning these Stellite6 bars into thermowell tips when we visited their plant in Manchester. Stellite6 is particularly resistant to erosion and is therefore the material most suitable for harsh environments like the pulverised coal dust supply for power station boilers.
Only Western European material suppliers are used to ensure guaranteed origin and can provide 3.1 Material Certification giving chemical analysis. They also have the capability to do Positive Material Identification (PMI) testing to ensure genuine supplies and to reverse engineer materials when diagnosing failed components.
