PPI AWWA C | C Statement
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.
Standard dimension ratio SDR: Nominal size and OD base such as 18 in. Pipe shall be provided with squarely cut plain ends in lengths and tolerances agreed on by the manufacturer or supplier and the purchaser. It is determined from awwq PC using Eq 2, 3, and 4. Specific policies of the state or local agency. In addition, consultation with PE pipe manufacturers is recommended. The defined surge capacities and corresponding allowable changes in flow velocities are stated in Table B.

The demands for installation of new pipelines, and revitalization of the deteriorating water pipe infrastructure are urgent and critical,” stated Tony Radoszewski, president of c9906 PPI, the major trade association representing all segments of the plastic pipe industry.
The inner surface of the pipe shall give no indications of brittle-like cracking or crazing when examined with the naked eye. The average failure time must meet or exceed the specified minimum average failure time, and no less than two out of the three specimens shall meet or exceed the specified minimum average failure time.
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 pipe is primarily d906 for use in transporting potable water wwwa either buried or aboveground installations. PE Pipe Design and Installation provides this information.
Two standards developed under the direction of NSF: Average inside diameter ID can be calculated as follows: Fittings described by this standard include fittings intended to be joined to PE pipe by thermal fusion. The dimensional tolerances for diameter and wall thickness shall be the same tolerance on a percentage basis as that specified for the average outside diameter and minimum wall thickness for the next smaller size.
Materials language has been added Sec. A specimen taken from the midwall area of produc- tion pipe shall be tested for thermal stability in accordance with ASTM D Sec. Use of Annex A procedures may not always be identical, depending on the certifier.
Its surge capacity per Table B. Log In Sign Up. Inthe Standards Awwz on Thermoplastic Pressure Pipe appointed a subcommittee to prepare a standard covering 4 in.
APPENDIX A. PRESSURE CLASS SELECTION PER AWWA C906
For each material, one pipe size from each size range shall be tested at the beginning of production and semiannually thereafter. Occasional surge wawa are caused by emergency operations.
In situations where different kinds of aswa 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.
The method for determining WPR is stated in Sec. In their latest editions, they form a part of this standard awwx the extent specified within the standard.
Any modification of the provisions, defini- tions, or terminology in this standard must be provided by the purchaser. When this situation exists, refer to the supplier for information on the hydraulic collapse resistance of the pipeline. Minimum marking on the pipe shall include the following and shall be applied so that intervals between markings are no greater than xwwa ft 1. Through our collective strength we become better stewards of water for the greatest good of the people and awa environment.
Hydrostatic design stress HDS: Peak pressure during a surge is equal to the sum of the pumping pressure and the transient surge pressure. In any case of conflict, the requirements of this standard shall prevail.
