Thermowell for Lap Flanges (Solid-Machined) - TW30
Brand: WIKA Alexander Wiegand SE & Co. KGEach thermowell is an important component of any temperature measurement 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 operation.
Features- Heavy-duty design
- Solid machined version without welding
- Possible thermowell forms:
- Design TW30-A: tapered
- Design TW30-B: straight
- Design TW30-C: stepped
- For lap flanges per ASME B16.5

Maximum Process Temperature, Process Pressure
- Depending on:
- Thermowell Design
- - Dimensions
- - Material
- - Flange pressure rating of the clamping flange
- Process Conditions
- - Flow rate
- - Density of medium
Hydrostatic Pressure Test
- As the assumed flange material, the TW30 thermowell material is used.
- This Non-destructive test is performed in accordance with ASME B31.3 using the,pressure values of the flange Standard ASME B16.5, depending on Pressure rating
- temperature Range and material within the corresponding Pressure-Temperature rating,table.
