PIPE AND PIPE SYSTEM

**************************************************************************

NOTE: When individual branch loops require

circulating pumps due to constant volume plant

system design or insufficient available differential

pressure for terminal unit control valve in a

variable volume plant system design, designer must

provide appropriate pump specifications herein.

Pumps shall be carefully sized for the specific loop

only such that operation of the main plant system

and other branch loops is not affected.

**************************************************************************

NOTE: If it is necessary to provide for additional

thermal expansion of piping, designer may provide

design and specification for either expansion

loop(s) or mechanical expansion joints for the

particular service, however, expansion loop(s) are

preferred.

High Pressure Piping System

**************************************************************************

NOTE: Specify the maximum pressure and temperature

leaving the central heating plant. Note that some

operating pressures may be substantially higher than

corresponding saturation pressures at the supply

temperature, depending upon the method of plant

generator pressurization (Booster pumps and

compressed gas pressurization methods produce
