ALLOWABLE PIPE SIZE, CLASS AND MATERIALS FOR

Excessive ovality of the pipe creates the potential for pipe collapse as well as future maintenance problems when repairing/replacing sections of pipe. The cost of the extra work and testing involved in laying and compacting around the pipe would be equal to or greater than the savings madeby purchasing lower class pipe.

This means that for a fixed volume of clean fill water, the hydrostatic pressure will decline slightly during the test time, as the polyethylene molecular chains stretch and align under high stress.

The pressure in the total pipe line must be considered before selecting the class of pipe. The pressure will vary along the length of pipe if it is at different elevations. Polyethylene pipe may 'suck flat' if a vacuum is present in the system. A vacuum is caused when water is allowed to flow down a pipe when the highest point is blocked off. Pipe Size Chart - Rolled Alloys, Inc.Nominal Pipe Size (NPS) is a North American set of standards used to designate pipe diameter and thickness. Pipe size is specified with two non-dimensional numbers:a nominal pipe size (NPS) for inside diameter based on inches, and a schedule (Sched. or Sch.) for wall thickness.
