PART 3 - EXECUTION

3.0 SYSTEM DESIGN

A. System design shall be in accordance with standard industry practice for thermoplastic industrial piping systems and the manufacturer’s instructions. The design shall take into consideration such factors as pressure and flow requirements, friction loss, operating temperatures, support spacing, anchoring, bracing and thrust blocking, joining methods, and thermal expansion and contraction.

B. A Hazen-Williams C Factor of 150 shall be used in all hydraulic calculations.

C. Maximum design temperature/pressure ratings shall not exceed the following:

Maximum Design Temperature/Pressure Ratings
