SECTION 01652 PIPELINE PRESSURE TESTING PART 1 - GENERAL 1.1 SUMMARY This Specification section covers the pipeline pressure testing associated with the Army’s Groundwater Pump and Treat System Modification installation at the University Villages Project. The University Villages Project is located at former Fort Ord, California. 1.2 REFERENCES The publications listed below shall form a part of this specification to the extent referenced and are referenced in the text by abbreviated designation only. Manufacturers Standardization Society of Valve and Fitting Industry (MSS) American Society of Mechanical Engineers (ASME) American Water Works Association (AWWA) American Society for Testing and Materials (ASTM) PART 2 - PRODUCTS Not Used PART 3 – EXECUTION 3.1 HYDROSTATIC TESTING OF CARRIER PIPES Carrier piping shall be visually inspected for mechanical completion and then hydrostatically pressure tested prior to being placed into service. Pressurizing equipment shall be equipped with a high pressure cut-out switch and/or high pressure water release valve that is field adjustable. 3.1.1 High Density Polyethylene Pipe Underground pipe composed of high density polyethylene (HDPE) shall be partially covered with backfill. Welds, fittings, and flanges shall be left uncovered during pressure testing where feasible. For double-contained pipes, the annular space shall be left open to the atmosphere during the test sequence. The test sequence shall follow Paragraph 3.1.3 below. 3.1.2 Polyvinyl Chloride and Stainless Steel Pipe Aboveground pipe composed of PVC and/or stainless steel pipe shall be adequately supported and secured with pipe clamps to support the weight and movement of the pipe and water. The test sequence shall follow Paragraph 3.1.3 below. 01652−1
