Hangers & Supports

Support location and spacing is dependent on the pipe diameter, the operating temperature of the system, and the location of any concentrated stress loads (i.e., valves, flanges, and any other heavy system components). Proper support spacing is critical to ensure that deflection is kept to a minimum. Hangers used must have an adequate load-bearing surface that is free of any rough or sharp edges that could damage the piping during use. Hangers must also not restrict linear movement of the system due to the effects of expansion and contraction. Overtightening of hangers/supports must be avoided.
