Application

Energy absorbers can be used as an alternative to shock absorbers in cases of minimal thermal movement. The free stroke can be adjusted (for medium sizes) within a range of ± 25 mm / 0.98 in. In this range the pipe system can move without resistance. If the displacement exceeds this range, movement is restricted by limit stops. Undesirable stress peaks are avoided through conversion of kinetic energy to deforming energy. Energy absorbers are ideal as:

  • protection against water hammer
  • a substitute for complex framework constructions
  • whip restraints
