High Density Polyethylene (HDPE) pipe has been used for decades in non potable water appliions. In particular, HDPE pipes are often preferred for their welded joints  . While special equipment is required to form the weld, welding eliminates the need for separate fittings, a common source of leaks and contaminant infiltration.
Plastics HDPE pipe on the surface transporting compressed air at 120 F. Per Table 3, this appliion is not recommended. Liquid Flows Short term internal pressure surges such as water hammer result from instantaneous liquid flow velocity changes. These
As a general rule, PE pipe for pressure appliions can be safely used at temperatures as low as 40 F ( 40 C) and as high as 140 F (60 C). For non pressure service, the allowable temperature range widens up to 180 F (82 C). There are a few PE piping
PE pipe systems are usually designed by our customers based on empirical and actual test data on the basis of a 50 year service life. Under normal operating conditions the actual life is expected to be considerably greater. Plastic pipes are made
This procedure can be used for HDPE pipe and fittings that have a grade designation (in accordance with ASTM D3350) of PE 3408/3608/4710. The pipe and fitting nominal melt HDPE Pipe PN16 SDR11 range would be . g/10 min. This procedure is intended only as a guide

Air valves are generally installed on liquid piping systems to exhaust air or gases and admit air to prevent vacuum conditions and air related surges. The AWWA Air Valve Manual recommends air valves at various loions including high points, long runs, adjacent to mainline valves, downstream of pumps and where there are changes in pipe slope.
Water can’t be compressed like the air or gas used by itself for pneumatic testing, so considerably less stored energy is generated. While there are still hazards associated with hydrostatic testing, MCAA recommends the use of hydrostatic testing
