Investigating seismic stability of REHAU cross-linked polyethylene pipelines

Summary

The results of experimental evaluation of seismic stability of REHAU pipelines of different trademarks and diameters are presented. The experiments were carried out on a vibroplatform of pendulum type with two degrees of freedom. The pipelines were filled with water at 10–95 C temperature and 7–11 bar pressure. From the experimental tests (impact tests and repeated pulse tests) the integrity of pipelines made of cross-linked polyethylene at vibration and frequency-amplitude range equal to 7–9 numbers on the MSK-64 scale was evaluated.
