In situations where different kinds of polyethylene piping materials must be joined to each other, the manufacturers of the subject pipe or fitting should be consulted to determine the appropriate fusion procedures. Colored products shall contain sufficient UV stabilizer in lieu of carbon black for 24 months of outdoor storage.

Through our collective strength we become better stewards of water for the greatest good of the people and the environment. Otherwise, examination of DR 17 with its surge capacity of 50 psig per Table B. Specimens shall be taken from the pipe and tested in accordance with the test method described in Sec. Aww this standard generally presents aawwa information for ordering pipe that meets project working pressure requirements, it does not include information to guide the designer in the determination of wall thicknesses, pipe flexibility requirements, and installation conditions to meet external loading conditions.

The maximum anticipated, sustained operating pressure applied to the pipe exclusive of transient pressures. The test pressure at failure shall not be less than that which results from a minimum hoop stress value of 2, psi These pressure ratings do not apply to loose or floating backup flanges on thermoplastic piping stub ends.

The demands for installation of new pipelines, and revitalization of the deteriorating water pipe infrastructure are urgent and critical,” stated Tony Radoszewski, president of the PPI, the major trade association representing all segments of the plastic pipe industry.

Minimum wall thicknesses in. Standard material code designation such as PE This standard describes PE pipe, fittings, and joints made from PE materials with one of the standard PE code designations as listed in Table 1. Standard dimension ratio SDR: PPI is the premier technical, engineering and industry knowledge resource publishing data for use in development and design of plastic pipe systems. For PE and PE materials, the minimum hoop stress value shall awww 2, c06 It is important that several specimens be tested to ensure that representative samples of the inside surface are tested.

The manufacturer should be consulted for more detailed recommendations. Description of fitting e.

When plant inspection is required by the purchaser, the manufacturer shall provide the purchaser with adequate advance notice of when and where production of ordered materials will begin.

The dimensional tolerances for diameter and wall thickness shall be the same tolerance v906 a percentage basis as that specified for the average outside diameter and minimum wall thickness for the next smaller size. A pipe may sometimes be subjected to net negative internal pressure because of the individual or combined effect of internal negative transients and external forces such as the water table.

Each fitting shall be designed and manufactured to operate at not less than the design pressure of the pipe system for which it is intended.

DR 21 may be used only if the designer can operate the water main at working pressure less than 70 psig, or if the surge at 5 fps was attributed to occasional events only x906 recurring surges at 4 fps or less refer to Table C. A test specimen taken from the midwall of the pipe shall comply with the requirement given in Sec. The PC values listed aawwa the table identify the maximum working pressure ratings WPR of pipe made and classified in accordance with this standard.

Fitting styles are characterized as elbows, tees, reducing tees, reducing laterals, branch saddles, flange adapters, mechanical joint adapters, and end caps. I agree to the Terms and Privacy Statement.

However, this standard also includes provision for specifying pipe with custom diameters and diameter ratios. B Modification of Standard The flange thickness shall be supported by calculations based on a safety factor agreed on by the purchaser and the supplier.

Occasional surge pressure is usually the result of a fire flow or a malfunction, such as a power failure or system component failure, which includes pump seize-up, valve-stem failure, and pressure-relief-valve failure.
