Flanged Thermowell is a protective device designed to house temperature sensors (such as thermocouples or RTDs) with a flange connection for easy installation and removal in process piping systems. It provides a robust barrier against mechanical damage, corrosion, and high-temperature environments, ensuring accurate temperature measurement and sensor protection.
Key Features of Flanged Thermowell:
Design: Cylindrical tube with a flanged end for bolted connection to a mating flange on the process piping or vessel.
Material Options: Common materials include stainless steel, Inconel, carbon steel, and other corrosion-resistant alloys.
Temperature & Pressure Resistance: Suitable for high-pressure and high-temperature applications, depending on material and design specifications.
Ease of Maintenance: Flanged connection allows for quick removal, replacement, or calibration of sensors without disrupting the process.
Typical Construction:
Body: Usually made from materials like stainless steel, Inconel, or other alloys.
Flange: Conforms to standards such as ANSI B16.5, DIN, or JIS, depending on regional requirements.
Sensor Insertion Point: Typically threaded or weld-in, designed to accommodate thermocouples or RTDs.
Socket Weld Thermowells are specialized protective enclosures used to house temperature sensors, such as thermocouples or RTDs, in industrial piping systems. They are designed to provide accurate temperature measurement while protecting the sensor from harsh process conditions.
Key Features of Socket Weld Thermowells:
Design: Compact and suitable for small-bore piping, with a socket weld connection for easy installation
Material: Commonly made from stainless steel (304, 316), alloy steels, or other corrosion-resistant materials depending on application
Connection: Socket weld end for secure attachment directly into pipe or fitting
Thermowell Shape: Usually tapered or straight, designed to withstand process pressures and temperatures
Standards: Manufactured according to ASTM, ASME, or other relevant standards
Advantages:
Easy to install and replace sensors without shutting down the system
Protects the temperature sensor from process fluids, pressure, and corrosion
Suitable for high-pressure and high-temperature environments
