The single expansion joint type is simply a bellows element with end connections. It is the least expensive type but requires that the piping be controlled as to the direction of the movements required of the unit. This type of expansion joint should not be expected to control the movement of the pipe. If the piping analysis shows that the expansion joint must accept axial compression, then the piping must be guided and constrained in other locations so that only that axial movement will occur. The flanges and bellows are fabricated from ASTM A240-316 stainless steel. The units are 6″ in diameter, 5″ long, and have an 11″ outside diameter. Design conditions are: design pressure = 150 psig, test pressure = 225 psig, design temp. = 200°F, axial travel = 0.625″ compression, axial spring rate = 803 lb/in., lateral offset = 0.125″, and lateral spring rate = 7,942 lb/in. *Designed in accordance with the Standards of the Expansion Joint Manufacturers Association, 10th E, and welding per ASME Boiler and Pressure Vessel Code Section IX.
