In buried plastic water pipes, the predominantly fluid-borne wave is of particular interest, as it plays a key role in the propagation of leak noise. Consequently, it has been studied by several researchers to determine the speed of wave propagation and ...

An analysis of the discarded drill pipes that had been used in wedge grips has revealed that the main reason for pipe rejection is the reduction of a pipe wall as a result of plastic deformations, due to damaging the pipe surface by the die teeth. The lo...
