Stainless Steel Thermocouple Protection Tube Thermowell With DN25 Flange

Stainless Steel Thermocouple Protection Tube Thermowell With DN25 Flange

1. Brief Introduction

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.

2. Characteristics

• Optional Tantalum sheath, which can be permanently attached, for added protection
• Wake Frequency, Flow-Induced Stress, and Process Pressure calculations can be made to support the thermowell design.
• Full penetration weld standard
• Wake frequency calculations
• Integrated Extension for simple installation
• Wide variety of material options

4. Application

The thermowell protects the instrument from the pressure, flow-induced forces, and chemical effects of the process fluid. Typically a thermowell is made from metal bar stock. The end of the thermowell may be of reduced diameter (as is the case with a tapered or stepped shank thermowell) to improve the speed of response. ​
