Energy dissipative tubes are provided, along with methods of fabricating and installing the energy dissipating tubes. An energy dissipative tube can include a length of tubing, a first resin layer surrounding the outside of the tubing, an expanded metal foil adjacent to the outside of the first resin layer, and a second resin layer surrounding the expanded metal foil and the first resin layer. Another energy dissipative tube can include a length of tubing, a conductive layer adjacent to the outside of the tubing, and an insulative layer adjacent to the conductive layer. A further energy dissipative tube can include a length of tubing, a metal layer adjacent to the outside of the tubing, and a resin layer adjacent to the metal layer.
