FTW Screwed Stepped Thermowell

FTW Screwed Stepped Thermowell are available for use with all Temperature Instrumentation and Control Products, including: Thermometers, Thermocouples, RTD’s, Temperature Recorders, and Temperature Controllers.

FAV range of FTW Screwed Stepped Thermowell protects and extends the usage life of a temperature sensor in critical process applications where the sensor is not physically compatible with the environment. Installed directly into the piping systems, Stepped Thermowell facilitate sensor replacement in high pressure pipelines and eliminate the need to interrupt the process flow or drain the process system for sensor maintenance function. FTW Screwed Stepped Thermowell are utilized when pressure, high velocity and corrosive process media exist. This serves to isolate and protect the sensing instrument, and permits removal of a sensing instrument without shutting down the process. A perfect solution for protecting the process and extending product service life.

FTW Screwed Stepped Thermowell are installed directly into the systems where protection of sensing equipment is critical , Stepped Thermowell facilitates the continuation of process flow in the system for sensor maintenance function.

FAV Thermowell has been specifically designed for use on instrumentation, process and control systems, together with equipment employed in oil and gas, marine and shipping, chemical, chromatography, petroleum. Straight Thermowell provide safe and reliable pressure measurement, while meeting challenging applications in Process Market like Chemical and Petrochemical Plants, Water and Wastewater pressure Control and Medical and Life Sciences Market like Pharmaceutical / Biotech and Food and Beverage

FAV FTW Screwed Stepped Thermowell are available in Stainless Steel, Brass, Steel, Monel, Hastelloy C, Incoloy, Inconel 600.
