The line is providing potable water to a subdivision and increased fire flow protection to an expanding community. “In many cases, pipeline construction is an eyesore to communities and traditional open-trench methods would be impossible for this project,” observed Tony Radoszewski, executive director of The Plastics Pipe Institute Inc. (PPI).

HDPE pipe is the perfect solution for municipal water supply and drainage system, urban water supply and drainage. HDPE pipes are increasingly popular worldwide for water supply and drainage because of its advanPE100 ISO9001es: Corrosion resistance: HDPE pipelines are resistant to corrosion by a variety of chemical media, and chemicals present in the soil do not cause any degradation to the pipeline.
20/9/· Fire pumps are covered in NFPA 20 and pipess for the storage of fire protection water is covered in NFPA 22. However, these standards won''t provide you information on amount of hydrants needed or water demand required. That''s something to be decided by the Puhui Pipe manufacturer in China

HDPE pipe strength, durability, flexibility, weight of light welding after the high density polyethylene to zero leakage rate, because the welding process formed a whole HDPE …
9/11/2009· Why fire pumps are not designed to ramp up pressure is beyond me and I haven''t found a reason. I have seen underground loops blown out by water hammer from testing of fire pumps. Also mains on the suction side have been collapsed, which may have been avoided if the pump ramped up and gave more time for pressures to equalize.
stacks and ground pipes. HDPE is highly resistant to abrasion; its extra thick walls offer additional protection. Heat expansion Heat expansion of HDPE needs to be considered in the design and installation. As a rule of thu, for every 50 C increase incan be

Generally 1inch hdpe pipesing, HDPE pipe is butt fused by applying heat to prepared pipe ends and then pushing the pipe ends together with a pre-determined force to make a permanent butt fusion joint. It is a very simple process utilizing a properly sized butt fusion machine for the pipe size to be joined.
I want to know that if there are some branches on the main pipe, then the angle of the branch would consider as a change of direction and there would be no need for expansion loop or offset. Or the length of the main pipeline is considered and the expansion loop
