| Application |
|
| Thermowells within the TWV series are machined from solid bar and
mounted between mating flanges for process insertion. This design of
thermowell will accept thermocouples (TC), resistance temperature detectors
(RTD), as well as mechanical and digital thermometers. |
| |
| The dimensions of the Vanstone flange corresponds to the mating raised
face diameter of the process flange.The Vanstone flange surface finish is
usually machined with a phonographic spiral serration to match the mating
process flange. During installation a gasket is inserted between the process
flange and the Vanstone flange to maintain a pressure seal. A top flange is
then placed over the Vanstone thermowell and bolted to the process
flange using the correct bolting torque forces for the bolt size and material. |
| |
| The required lap flange is not standard and can be provided as an optional extra. |
