This research is a fundamental study intending to develop industrial piping supporting restrainers which utilizes excellent energy absorbing behaviour of super plastic alloy materials. In order to achieve this purpose, energy absorbing effect of the super plastic alloy itself is examined, in the beginning, taking a Super Plastic Zinc (Zn 22% Al) as a representative material. In the next place, damping effect for piping system is investigated by shaking test whereby two types of simplified piping model having SPZ restrainer are introduced. From the shaking test it has become clear that dynamic energy absorption of SPZ restrainer for piping is conpicuous particularly in fairly high temperature circumstance (T > 120°C) comared with steel or brass restainers.
