CONVAL® calculates critical values for stress and frequency of thermowells in pipelines and compares these values to the allowed limiting values. Temperature dependent values for the maximum allowable working stress, the elasticity modulus and the density are available for many materials.
Graphical stress analysis: Stress analysys of a thermowell calculation. The actual frequency ratio of the 2nd operating point is between 40 and 60%.Therefore, the device is not conforming to the standard
The CONVAL® stress pass/fail analysis provides a quick overview of whether the calculation complies with the standard. A color-coded traffic light system immediately points out problem areas.
Pass/Fail view of a thermowell calculation. The conditions for the steady-state stresses, the dynamic stresses, and the hydrostatic pressure are fulfilled (green light). The conditions for the dimensions and the frequencies of the 1st and 3rd operating point are not fulfilled (red light).
