Surge pressure caused by emergency pump and valve operations are usually severe. The following allowable surges are in addition to static pressures: Help Center Find new research papers in: Fabricated fittings shall meet the minimum dimensional requirements and tolerances of the pipe at the point of fusion.
The elongation-at-break test Sec. These pressure ratings do not apply to loose or floating wawa flanges on thermoplastic piping stub ends.
PE pipe materials shall contain at least 2 percent finely divided and well-dispersed carbon black. Because of its apparent nominal working pressure capacity, the preliminary design choice for this application is pipe of DR 17 designated as PC with a maximum working pressure rating of psig.
