Slow Crack Growth-Notches-Pressurized Polyethylene Pipes
A general method for predicting the life time of a polyethylene structure that fails by slow crack growth was applied to the case of externally notched pressurized pipes. An analysis of experimental data indicated that the residual stress must be taken into account. The critical notch depths associated with a given life time were calculated as a function of pipe size, PENT value of the resin an...
متن کاملMobile NMR for Analysis of Polyethylene Pipes
NMR relaxometry is a suitable tool to determine the morphology of semi-crystalline polymers by its ability to discriminate between rigid, mostly crystalline and soft, usually amorphous material. The NMR-MOUSE◦R (nuclear magnetic resonance mobile universal surface explorer) was explored in this work to supply morphological data of poly(ethylene) pipes nondestructively. PE-100 pipes were investig...
متن کاملUltrasonic phased array inspection of electrofusion joints in polyethylene pipes
The use of plastic as a pipe material for the transport of gas and water has increased over the last few years, attributed to the significant advantages of this material such as corrosion resistance, strengthto-weight ratio, lightness, flexibility and cost. Consequently, these pipes have a long predicted service life. One of the pipes’ joining processes is electrofusion welding. As for all kind...
متن کاملAcoustic Wave Propagation in Water Filled Buried Polyethylene Pipes
Axisymmetric acoustic wave-modes propagating along buried water pipes have been investigated by the method of finite elements and experimentally. High precision dispersion relations are presented in this paper as a function of the geometry, the embedding material and the elastic modulus of the pipes. It is found that at low frequencies the fundamental axisymmetric acoustic mode of the water cyl...
