TA557 bar stock thermowell, thermowell made from drilled bar stock, mainly for demanding applications or general use
-
Advantages
-
The extension length, insertion depth and dimensions of the thermowell can be selected according to the process requirements
-
A wide range of standard materials and process connections available, or customized to specification
-
Different grades of surface finish selectable
-
Thermowell shape: straight or tapered
-
Process connection by thread or fixed flange
Field of application
Because the process conditions are demanding, the strength of the thermowell must be calculated precisely. Dye penetrant testing, ultrasonic testing, helium leak testing, pressure endurance testing and various non-destructive material tests prove the quality of the materials and workmanship.
