Abstract

Due to certain civil engineering activities, e.g. road construction, the safety factor of already working high pressure oil and gas transmitting pipes in the vicinity should be previously increased. For doing so the relatively new, but well proved, pipe guard technique is applied many times, by which several layers of glass fiber reinforced epoxy material is applied to the external cylindrical surface. For the knowledge of the mechanical behaviour and for the possibility of the standardisation of this new anisotropic and heterogeneous structure an analytical procedure and a computer program has been worked out in the frame of linear elasticity. In parallel, a number of experiments were also carried out for example for the determination of the pressure-volume change characteristics and for that of the bursting pressure. Results of the analytical calculations and experiments were compared and a good correlation was found.
