Yard Piping Economy

The main arterial system of a plant is yard piping. It is here that long process lines are located interconnecting distant equipment with lines entering and leaving the unit. Also located in the yard are utility headers supplying steam, air, gas, and water to process equipment. Here are located all relief and blow-down headers. Often instrument lines and electrical supply conduits are also supported on the yard steel. 

Equipment arranged along but not associated with the yard increase yard piping cost unnecessarily. A control house located along the yard, for example, will increase yard piping cost because all lines must pass by without really being associated with the relatively long control house.

Pipe economy depends primarily on the length of lines arranged in the yard. Fittings, valves and instruments are relatively few compared to pipe length.
