TA571
Barstock thermowell

TA571
Barstock thermowell ©Endress+Hauser

Made of drilled barstock material. Mainly used in heavy duty or general purpose applications.

Due to the challenging process conditions by heavy duty applications the load capacity of a thermowell must be calculated exactly. Dye penetration tests, ultrasound test, helium leakage test, pressure endurance test as well as various, non-destructive material tests prove the quality of materials and processing.
