Thermowell with flange Model TW10 - WIKA

1 TemperatureThermowell with flangeModel TW10 Thermowell with flange , Model TW10 Applications Petrochemical industry, on-/offshore, plant construction For high process loads For high chemical demandsSpecial features Heavy-duty design Coating for corrosive or abrasive process loads Possible Thermowell forms: tapered, straight, stepped Design TW10-F:Full penetration weld versionDesign TW10-P, TW10-R: with double weld seamDesign TW10-S, TW10-B:Screw-welded designWIKA data sheet TW 1 of 6 WIKA data sheet TW 01/2022 DescriptionEach Thermowell /protection tube is an important component of any temperature measuring point. It is used to separate the process from the surrounding area, thus protecting the environment and operating personnel and keeps aggressive media, high pressures and flow rates from the temperature sensor itself and thereby enables the thermometer to be exchanged during on the almost limitless application possibilities, there are a large number of variants, such as Thermowell /protection tube designs or materials.

2 The type of process connection and the basic method of manufacture are important design differentiation criteria. A basic differentiation can be made between threaded and weld-in thermowells/protection tubes, and those with flange , one can differentiate between protection tubes and thermowells. Protection tubes are constructed from a tube, that is closed at the tip by a welded solid tip. Thermowells are manufactured from TW10 series of thermowells with flange connection are suitable for use with numerous electrical and mechanical thermometers from to the heavy-duty design, these international design thermowells are the first choice for use in the chemical and petrochemical industries and in plant 2 of 6 WIKA data sheet TW 01/2022 SpecificationsBasic informationThermowell form Tapered Straight SteppedVersionsDesign TW10-FFull penetration weld versionDesign TW10-PWith double weld seam (weld seam strength 3 mm)Design TW10-RWith double weld seam (weld seam strength 6 mm)Design TW10-SScrew-welded design, weld seam does not come into direct contact with the mediumDesign TW10-BScrew-welded design, additional weld seam on the process side (sealing joint)Material (wetted)
