Abstract
The project, in collaboration with Vallourec, is about sealing of tubular connections and the role of surface properties and their evolution in relation to sealing. We want to understand what surface morphological parameters influence sealing, what the effect of lapping is, and link surface properties obtained from in situ tests (production line) to laboratory tests (bench tests).
Four steps can be drawn: 1) generating and controlling surfaces after machining, 2) evolution and modification of asperities during screwing and the state of the surface after friction, 3) description of the tribo-system, 4) impact of surface conditions, material mechanical properties.
