Why is it necessary to monitor the risk of bolt stress imbalance?

During operation, bolts may experience stress changes due to load fluctuations, temperature changes, corrosion wear, or installation errors, which can lead to the risk of loosening or fracture of pre tension. For example, the fracture of flange bolts in pressure vessels may lead to the leakage of toxic media; Loose bolts in the wind turbine tower may cause overturning due to increased vibration. Therefore, real-time and accurate monitoring is a "must-have" for industrial safety.

The limitations of traditional monitoring methods: why online monitoring

More crucial?

In the past, bolt stress monitoring relied on manual inspection or offline testing, which had problems such as poor timeliness, one-sided data, high operational risks, and high maintenance costs. Online monitoring devices can capture stress fluctuations at any time through real-time data collection and remote transmission,canAddressing the aforementioned shortcomings has become a standard feature of modern industrial operation and maintenance.
