TA555
Barstock thermowell

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.
