WHY CHOOSE SHUANGLIN HDPE SPIRAL PIPE #part 3

Desember 13, 2021 by admin in Industry News, Uncategorized

INTERNAL ROUGHNESS
HDPE has the lowest Manning coefficient (internal roughness) compared to other materials on the market.
HDPE manning coefficient is 0,010 smoothess than maning coefficient is 0,014.

Therefore, under the same hydraulic design conditions (section, slope) with traditional technology, HDPE high-density polyethylene pipes have greater hydraulic capacity.
When comparing HDPE pipes with Concrete pipes, it can be deduced that:
– To conduct the same amount of flow, SPIRAL high-density polyethylene pipes need a diameter 10% smaller than that required for concrete pipes.
– In the case of having the same diameter in HDPE and in concrete, the HDPE will conduct 30% more flow.
– To conduct the same flow and with equal diameters, HDPE pipes will need a 40% lower longitudinal slope than that of concrete pipes, with the corresponding reduction in capping and the consequent savings in excavation.

EFFICIENCY AND SPEED OF INSTALATION

Due to the low weight of the pipes, the logistics are carried out with light equipment, which also helps to load the trucks efficiently and safely. The optimization of transportation lies in the possibility of sending deep-drawn pipes, thus reducing costs and increasing the capacity of shipments. For its part, the handling of light pipes reduces the risks of work and the use of heavy machinery, since the collection can be solved in confined spaces at the foot of the trench, allowing the pipeline lowering operation to be streamlined.
