What are they used for:

Take pumping pit Seawater

Systems water intake built in high density polyethylene ((HDPE acronym in English) are intended for the abstraction of water from a natural source such as:. Seas, lakes or rivers These systems are used for supplying water for various purposes such as providing drinking water or process water, for desalination of water for cooling systems for air conditioning systems and for the production of clean energy.

Various water intake constructions have been built around the world with pipes High Density Polyethylene, given the extraordinary advantages of the material and technological advances in this type of construction with HDPE. Thanks to the properties of HDPE, these systems can be designed to achieve longer life (over 60 years) with the goodness of being maintenance-free, because it does not suffer the effects of corrosion that attacks other traditional materials. The experience of the last five decades, several projects around the globe, leads to the conclusion that “when systems submerged pipe it is, is the HDPE option more advantages,” because you can count on a cost curve vs lowest since the initial investment, with shorter project execution and technology involving the marine environment amiably time.

Communicating Vessels System:

A water works simply, an example can be seen in the model of “Taking Seawater System Vessels by Comunicantes”. It consists of a pit built on land below sea level, which is connected to the marine environment through a HDPE pipe and a filter that prevents the entry of particularly thick; on the grave of communicating vessels is a pump that sucks the salt water to be stored in a tank or to be directly used in the application to which it is intended.

For the calculation of the pipe must have studies bathymetry and marine currents in the area to be installed, in order to calculate the stability of the pipeline on the seabed and ensuring water quality at the point of uptake (low suspended particles). This is installed with reinforced concrete counterweights that are attached to the pipe; They are built in several long stretches (eg 300 m in length) which are flanged at sea to interconnect; finally ditched the pipe to remain buried in the seabed, especially at depths less than 10 m is required.
