Hubert - Structural Test (1) Service
The test examines potential deformation by applying a number of pressure cycles to the mesh to determine whether the mesh will withstand service at its maximum design pressure. Several mesh panels can be tested on request of our client at various pressure cycles. The number of movements (amplitude caused by water pressure + spray pipe) corresponding to the design values simulate the requested lifetime. Linear Variable Displacement Transducers (LVDT’s) continuously capture displacement measurements at various positions on the mesh whilst also recording pressure and temperature measurements.
The tests can be eentually witnessed by representatives from our clients. For example, we have implemented these tests for nuclear power plant projects in France, with our customer REEL/EDF present. They assess the structural strength of the proposed mesh panels to be used for the (vertical) drum screen, being a key part of the cooling water intake screening system, used to cool both the electricity generating steam-cycle and the nuclear reactor services.
