Cadweld Plain Strap Bonds

In colder climates, water distribution pipes occasionally freeze in the winter. To thaw the ice, a high current (for example, from a welding machine) is applied to heat the pipe and thaw the ice. To accomplish this, each pipe joint must be efficiently bonded to control the electrical path and to prevent burning the pipe gaskets. 3/4″ wide copper bonding straps, welded to the pipe with CADWELD connections, provide the necessary bond or current path across the pipe joints. The bonding strips have been tested at over 500 amperes. The straps may also be used to provide continuity for Cathodic protection or grounding systems.
