Measuring creep deformation at high temperatures

Measuring creep deformation at high temperatures

ID: F1601-07

Scientists developed an unique approach for checking the integrity of components operating under harsh conditions at power stations. Extreme temperatures and stresses in engineering elements such as steam pipes in a power plant may cause weld cracks that may develop until the pipeline breaks. Nevertheless, present creep strain measurement techniques are difficult to apply in a power plant because of to oxidation at high heat over a prolonged duration of time. The absence of long-term precise creep dimension leads to poor creep life prognosis, placing European power generation infrastructure at risk. Researchers initiated a project to accurately determine creep deformation and expand component life beyond the original design limitations in power stations. The project utilized digital images for long-term creep measurement and tracking of pipework where direct sensor accessory and human access are hard or dangerous. Scientists incorporated a digital digital camera equipped with a telecentric lens into a compact model system that allows brief deployment on an energy plant pipe. They also fabricated a protective casing for the assessment coupon and trialled it on an ex-service pipe. To create a high-density grid pattern on the examination coupon, experts formulated a micro laser cladding procedure, developed built-in software that allowed the operator to get pictures and calculate strain based on electronic picture correlation analysis. Based on a model and area creep strain measurements, the project developed a methodology to anticipate component remaining life and incorporated it in the system. Comprehensive analysis of the accelerated creep test data acquired from two different pipes revealed that the system is capable of supplying extremely accurate creep stress measurements.
