Expansion loops in polyproplene pipes

[construction786]

Polypropylene pipes are used to convey domestic cold and hot water supply and hot water return to and from the toilets and kitchens of the hospital. The expansion coefficient of the selected pipe material is very high and the manufacturer's catalogues call for expansion loops after ever 30 feet of straight run. The U shaped expansion loops after every 30 feet are very difficult to manage in the constricted space above the false ceiling, due to the host of other adjacent services. Are there any other type of expansion joints (such as the flexible connections rubber or bellows type for steel pipes ) that are suited for PP pipes that would not require so much space.
