Allpiping engineersare well acquainted with expansion loops in the piping systems. Whenever thermal displacements are more than a certain value these expansion loops are added to absorb the displacement inside the expansion loop. These are mainly required in any piping system design to Reduce system ...
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 (...
Expansion coefficient (10-6 in/in oF) Initial temperature (oF) Final temperature (oF) Outside diameter of pipe (in) Load Calculator! The L-loop calculation is based on equation L = 0.063 (dl D)1/2 (2) where L = length of loop (m)Sponsored...
A detailed numerical representation of the behaviour of a meshed DH network requires the calculation of the local pressure and temperature of the water at all network piping junctions. In fact, these are fundamental to determine the mass and heat flow rates in the network, which are in turn ...

Ij = 1 N ∑ ijk × Fk k Tk (1) In Equation (1), Fk represents the output flows (e.g., length of pipe to be produced) of the system processes, and Tk represents their lifetimes. Values, data sources and calculation assumptions for ijk, Fk and Tk are presented in Pericault et ...
