Primary Use High-density polyethylene (HDPE) PE4710 pipe for potable water appliions or appliions requiring certifiion to AWWA standards. DriscoPlex ® 4000 / 4100 series PE piping can also be utilized for a variety of non-potable water appliions, including raw water, process water, sewer, and industrial appliions.
coination of municipal fire administration and fire protection engineering experience provides him with unique insight into the challenges of design and operation of municipal water supplies. He received his Ph.D. in Public Administration from China University in Washington, DC.
The use of corrugated HDPE pipe with recycled content per ASTM F2648 for drainage appliions is increasing. What Is Notable About Your Pipe: “As municipalities face the daunting task of replacing their cruling underground infrastructure they are finding a highly economical and sustainable choice in HDPE …

Due to intermittent use of the fixtures in a water supply system it can be difficult to predict and size the supply and service lines. The fixtures total theoretical demand should always be compensated with a statistic more expected demand. With the Water Supply Fixture Units system defined by the Uniform Pluing Code (UPC) there are tables available where the total demand calculated by Puhui Pipe manufacturer in China
Bypass piping is required where the water supply is considered to be of “material value” to the fire protection system without the use of the fire pump. While this is a rather subjective requirement,bypass lines are usually required where the water supply is provided by a pressurized fire service main such as municipal waterworks or private fire service main.
• HDPE pipes; Due to its high elasticity properties, for use in areas where a lot of seismic activity is very comfortable. It can orient itself according to the direction of movement of …
the pipe shall not exceed 5 ft/s ( 1.5 m/s) and for fire flow about 8 ft/s (2.4 m/s) to 16.2 fps (5 m/s). Example: Working Pressure and Surge Assessment of 12” DIPS DR18 PVC pipe and 12” DIPS DR17 PE4710 HDPE
Unit sizes provided in the table 1 and table 2 is in mm, but the size of pipes in the chart is in inch. 1 inch= 25.4mm, 1 ft. = 304.8mm, 1 gallon/m=3.785L/m. Water velocity should not be greater than 2.438m/s at valve seat to prevent noise and erosion. So, Pipe
