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.
