Abstract
A pipe restraint (20) permits thermal expansion of a piping system (10), while inhibiting movement of the piping system during dynamic events and providing vibration isolation. The pipe restraint includes first and second displacement members (22) and (24), which are interconnected by a restraining mechanism (32) for restraining displacement of the first and second displacement members relative to one another. The restraining mechanism includes first and second portions, which generally oppose one another relative to the central axis of the restraining mechanism. The restraining mechanism further includes third and fourth portions, which also generally oppose one another relative to the central axis of the restraining mechanism. The third and fourth members are offset circumferentially about the central axis from the first and second members. The first and second portions are connected to one of the displacement members, while the third and fourth portions are connected to the other displacement member. The first, second, third, and fourth portions of the restraining mechanism are interconnected by a helical coil of energy absorbing wire rope.
