DREDGING PIPE

From the beginning of civilisation, people, equipments, commodities and materials have been transported by water.

Since the natural phenomena of siltation and sedimentation threaten the navigational depth of rivers and their deltas, people constantly fight a battle against siltation through Dredging. Dredging is defined as the underwater removal of soil and its transport from one place to another.

Without dredging, ground-breaking projects such as the construction of the Suez Canal, the Panama Canal and Palm Island would not exist. More importantly, dredging is vital to our social and economic development. Much of the infrastructures has a direct link to dredging. There is a growing need for dredging in many applications, both large and small, in either capital or maintenance works. Dredging is everywhere and offers a world of opportunities.

Some of the most common types of dredging projects are:

• Channel and port maintenance, construction or deepening (capital dredging)

• Coastal protection and beach nourishment

• Land reclamation

• Mining and aggregate dredging

• Offshore works

• Improvement of the environment

Polyethylene (PE) used for the production of pipes was developed starting from the 1950s through successive generations (from PE32 to PE100) becoming one of the most widely used materials in the world for the construction of underground networks, for the transport of water and gas, thanks to its excellent hydraulic and mechanical performance and lower installation and maintenance costs compared to steel, cast iron, stoneware and cement.

Polyethylene pipes are highly competitive in terms of reducing the losses of the transported fluids, as evidenced by decades of experience. The particular properties of the PE also make it suitable for replacing or rehabilitating of exhausted existing pipelines. LIGHTNESS

facilitates the transport and movement of the tubes; Tenacity

the use of polyethylene gives the duct a good impact resistance even at low temperatures; the viscoelasticity of the material also entails a considerable reduction in the effect of water hammering and stress induced by the laying activity and the stresses of the ground;

High Lenght

Tubes up to 110 mm in diameter. the bars can be supplied in rolls, up to 13.50 meters, thus reducing the number of joints

Reliability

The PE can be welded with simple techniques such as welding with thermal elements by contact (head to head) or by electrofusion

Flexibility

It allows to make the joints even outside the excavation and to subsequently lay the pipes adapting them to the layout, reducing installation times and costs

Alternative installations

For the rehabilitation of existing networks, in addition to traditional laying techniques, it is possible to use trenchless techniques that reduce social and environmental discomforts

High absorbing capacity

Due to, for example, settlements, earthquakes or frost

No Corrosion

NO CORROSION AND HIGH RESISTANCE TO CHEMICAL AGENTS.

Friendly coefficient and min, fairing

The PE pipes have characteristics that reduce pressure drops, allowing higher flow rates for the same diameter and eliminating the formation of scale, guaranteeing hydraulic efficiency over time Useful Life

With a life expectancy of MORE THAN 100 YEARS FOR THE PE100.

HDPE PE 100 PIPES
