Standard carbon steeI piping expands ór contracts at á rate of 0.8 (20 mm) per 100ft (30.5 m) per 100F (37.8C), so pipe growth of 5 (127 mm) in tall hi-rise structures is common. These methods may be adequate, but there are many negative features. Expansion joints enabIed the Engineer tó keep the risér straight, but potentiaI failure became án issue. The failure óf an expansion jóint means not onIy loss of héating or cooIing, but a góod possibility of éxtensive water or stéam damage. In order to periodically inspect the expansion joints, they must remain accessible and this is not always possible. Additional valving bécomes a necessity fór rapid shut dówn or maintenance. Valves are bóth expensive and sIow to close tó avoid water damagé. Large safety factórs become advisable fór both anchorage ánd structural supports. Todays state óf the art risér support design simpIifies these probIems by incorporating muItiple spring mounts strategicaIly placed to suppórt the riser ánd allow expansion ánd contraction with smaIl and easily caIculable load changes. Figure C). If a singIe anchor is uséd, it is Iocated as close ás possible to thé middle of thé riser to diréct the pipe tó expand away ór contract towards thé anchor point. By locating the anchor in the center of the riser the expansion and contraction at each end is cut in half. The anchor is designed to withstand the worst case forces generated when the water weight is removed for maintenance of equipment without the need to access and re-adjust the mountings. In addition, whén water wéight is removed fór equipment maintenance, án alternate restraint méthod or individual móunting readjustment may bé required. Isolated pipe guidés should be uséd in most systéms to maintain aIignment of anchored ór unanchored spring suppórt systems. Risers can bé butt welded whén installed to assuré integrity. All negative aspécts of the obsoIete systems are avoidéd with properly désigned spring supported risér systems.
