One piece flexible expansion loop for rigid piping systems

A piping system for hot water-based fluid substantially above ambient temperature (10) includes at least one horizontal pipe run (20, 22). Each horizontal pipe run includes at least one flexible expansion loop (40, 42). Each flexible expansion loop is comprised of a unitary flexible body (70) which...

Beschreibung
Zusammenfassung:	A piping system for hot water-based fluid substantially above ambient temperature (10) includes at least one horizontal pipe run (20, 22). Each horizontal pipe run includes at least one flexible expansion loop (40, 42). Each flexible expansion loop is comprised of a unitary flexible body (70) which includes opposed generally linear end portions (72, 74). Curved portions of the flexible expansion loop (76, 78, 80, 82) are curved and extend transversely away from the common axis (48) of the horizontal pipe run. The flexible expansion loop is operative to accommodate changes due to the thermal expansion, water hammer and vibration while being more compact than conventional expansion loops.
