Pipe whip restraints are commonly used in the nuclear industry. They dampen and absorb the kinetic energy of bursting pipes in emergency cases. For this purpose, the elongation capacity of the encompassing U-bolts is used, as they are designed to absorb the expected dynamic loads. Pipe whip restraints are safety-related components. There are thus high demands on quality, design and manufacturing. LISEGA is a large-scale supplier to the latest generation of nuclear plants and has successfully proven its qualification to supply this specific design. Pipe whip restraints are designed and manufactured based on the customers’ requirements.
