This guide contains discussion of PVC pipe and fabricated fittings, including materials, products, and quality testing. Detailed discussion of pipe design parameters is included, along with a design example for cyclic surge pressures. TABLE OF CONTENTS. CH 1.0 - INTRODUCTION ..................................... 4.
The following Pipe Dimension Reference chart is for quick reference to some of the commonly used sizing classifications and nominal sizes. The following pages give additional detail for widely used PVC & CPVC pipe in IPS and CTS sizes.
Example: A 2" PVC schedule 80 pipe carries a fluid with a specific gravity of 1.2 at a rate of 30 gpm and at a line pressure of 160 psi. What would the surge pressure be if a valve were suddenly closed? From table 1: C = 23.9 p = (3.35) (26.3) = 88 psi Total line pressure = 88 + 160 = 248 psi Schedule 80 2" PVC has a pressure rating of 400 psi ...
