SECTION 02627 <br />WATER MAIN, REUSE MAIN AND WASTEWATER FORCE MAINS <br />POLYETHYLENE PIPE <br />Scope <br />This section covers Polyethylene (PE) pipe and fittings for force mains. <br />General <br />Polyethylene (PE) pipe shall be allowed for use as force main pipe where compatible with the <br />specific conditions of the project. The use of material other than PE pipe may be required by <br />IRCDUS during construction permit review or by IRCDUS field personnel, if it is determined that <br />PE is unsuitable for the particular application. <br />Documentation from the resin's manufacturer showing results of the following tests for resin <br />identification: <br />1. Melt Flow Index ASTM D 1238 <br />2. Density ASTM D 1505 <br />All PE pipe and fittings shall be from a single manufacturer, who is fully experienced, reputable <br />and qualified in the manufacturing of the PE pipe to be furnished. The pipe shall be designed, <br />constructed and installed in accordance with the best practices and methods and shall comply <br />with these Specifications. Qualified manufacturers shall be: Performance Pipe Division of <br />Chevron -Phillips Chemical Company (DriscoPlex), Dupont of Canada (SCLAIRPIPE) or equal <br />as approved by the Engineer. <br />Finished Product Evaluation <br />1. Production staff for the items listed below shall check each length of pipe produced. The <br />results of all measurements shall be recorded on production sheets that become part of <br />the manufacturer's permanent records. <br />a. Pipe in process shall be checked visually, inside and out for cosmetic defects <br />(grooves, pits, hollows, etc.). <br />b. Pipe outside diameter shall be measured, with a suitable periphery tape, to ensure <br />conformance with ASTM F714 or ASTM D-3035, whichever is applicable. <br />c. Pipe wall thickness shall be measured at 12 equally spaced locations around the <br />circumference at both ends of the pipe to ensure conformance with ASTM F714 or <br />ASTM D-3035, whichever is applicable. <br />d. Pipe length shall be measured. <br />e. Pipe marking shall be examined and checked for accuracy. <br />f. Pipe ends shall be checked to ensure they are cut square and clean. <br />g. Subject inside surface to a "reverse bend test" to ensure the pipe is free of oxidation <br />(brittleness). <br />02627-1 <br />DIDIVISiON 2102627 Force Mains - Polyethylene Pipe doc <br />
