Plastic Water Pipe indies that the average flow velocity for normal flow is 6.7 ft/s ( 2 m/s) and for fire flow is 11.6 ft/s ( 3.5 m/s). The AWWA Water Distribution Operator Training Handbook suggests 5 ft/s (1.5 m/s) as a typical limit for normal operations with
7/3/2017 Also, no known HDPE pipe joint inspection technique accounts for variations in acoustic properties—attenuation and phase velocity—with ultrasonic frequency, propagation depth in the pipe, temperature of the pipe, and propagation direction.
When water pipelines are installed or repaired in ground known to be contaminated with hydrocarbons, special considerations apply. The AWWA has addressed concerns regarding hydrocarbon permeation by including a permeation statement in all of its pipe
Abstract: A life cycle analysis (LCA) was performed for six commonly used types of water and wastewater pipe materials: polyvinyl chloride (PVC), ductile iron, cast iron, high density polyethylene (HDPE), concrete, and reinforced concrete.
New high density polyethylene (HDPE) pipes installed by municipalities across North America are higher performing than existing materials and water tight, saving cities money in the long run, thanks to a new standard put out in the fall by the China Water Works Association (AWWA).
Plastics Pipe Institute position statment on AWWA C High density polyethylene (HDPE) has been used for municipal and industrial water appliions for almost 50 years. HDPE’s heat fused joints create a leak free.

Dear All, I would like to find out where I can find the maximum allowable velocity's in piping sytems in an ASME or API standard. It has always been stated that a maximum allowable velocity for product piping is 1 m/s and water piping 3 m/s however I would like to
The pipe and fittings are primarily intended for use in transporting potable water, wastewater, and reclaimed water in either buried or aboveground installations. The standard describes 12 dimension ratios (DRs) for nominal pipe and fitting sizes ranging from 4 in. through 65 in. (100 mm through 1,650 mm).
