AWWA C defines working pressure as “the maximum anticipated, sustained operating pressure applied to aww pipe exclusive of transient pressures. Although this standard generally presents adequate information for ordering pipe that meets project working pressure requirements, it does not include information to guide c960 designer in the determination of wall thicknesses, pipe flexibility requirements, and installation conditions to meet external loading conditions.

Compare the pipeline working pressure with the pipe’s aawa class. In order to facilitate this procedure, the ring obtained in paragraph 5. Some variations from this format may be found in a particular standard. The test results shall be within the limits established by the supplier or manufacturer. Occasional surge pressure POS: Fittings that are produced by injection molding shall be tested once per production run.

These allowances and the methods for determining pressure class are stated in Sec.

This test shall be performed daily or at least once per production run, whichever is more frequent, on specimens prepared as described in Sec. The factor that is used to reduce the hydrostatic design basis HDB to arrive at the hydrostatic design stress HDS from which the pressure class PC is calculated.

Determine current information on product certification. This test shall be run on samples from the pipe at least once per day.

The inside and outside surfaces shall be semimatte to glossy in appearance and free of sticky or tacky material. DR 17 pipe with maximum working pressure rating of psig, also designated as PC Evaluate WPR as described in Sec. This standard presents cri- teria related to the manufacture and purchase of polyethylene pressure pipe to be used in the transmission of potable water in either buried or aboveground applications. The resultant net peak stress during the surge event remains less than the peak stress capability of the pipe; therefore, long-term performance is assured.

The tested pipe shall comply with the requirements given in Sec. The design should consider possible system reactions and their potential effect on system components. Inthe Standards Committee on Thermoplastic Pressure Pipe appointed a subcommittee to prepare a standard covering 4 in.

An example of the procedure used to determine the WPR for a pipe in a certain set of assumed operating conditions is provided in appendix C.

The elongation-at-break test Sec. The flange thickness shall be supported by calculations based on a safety factor agreed on by the purchaser and the supplier. Standard dimension ratio SDR: Pipe shall conform to the applicable dimen- sion requirements specified in Tables 3 through 8 of this standard and to any other dimensional requirements stipulated in the applicable standards referenced in Section 2.

Hydrostatic design stress HDS: Joining methods shall be capable of conveying water at the design pressure of the piping system. B Modification of Standard Carbon-black levels shall be determined daily or for each production run of pipe, whichever is more frequent. Fitting styles are characterized as elbows, tees, reducing tees, reducing laterals, branch saddles, flange adapters, mechanical joint adapters, and end caps.

Whenever possible, water column separation should be avoided. Users of this standard should consult the appropriate state or local agency having jurisdiction in order to 1.

Minimum marking on the pipe shall include the following and shall be applied so that intervals between markings are no greater than 5 ft 1. Colored coextrusions and pipe striping are allowed according to other provisions of the standard. AWWA is the largest organization of water professionals in the world.

Each length of pipe surface shall be visually checked inside and out for defects as described in C960. Pressure class PC ratings for pipe described in this standard are given in Table 9. Updates in C include: Compare the pumping pressure 85 psi with the available pressure classes in Table A
