The marine environment has high salinity, strong corrosiveness, high pressure and complex fluid dynamics, which places extremely high demands on the durability of pipeline materials. High-density polyethylene (HDPE) pipes have become an ideal choice in marine engineering due to their excellent corrosion resistance, anti-biological adhesion ability, lightweight and flexible design. This article will deeply explore the application, technical advantages and future development trends of HDPE pipes in the marine field.

 

The core advantages of HDPE pipes in marine environments

1. Excellent corrosion resistance

Chloride ions, hydrogen sulfide (H?S) and microorganisms in seawater are easy to corrode metal pipes, while HDPE is completely unaffected and does not require anti-corrosion coating or cathodic protection.

It is suitable for transporting seawater, salt water, acidic or alkaline media, such as seabed mining, seawater desalination and other scenarios.

2. Anti-biological attachment

Compared with metal and concrete, HDPE has a smooth surface and is not easily attached by marine organisms such as barnacles and algae, reducing maintenance requirements.

It can be combined with antibacterial modified HDPE (such as adding nanosilver) to further inhibit microbial growth.

3. Lightweight and high flexibility

The density is only 1/8 of that of steel, which is convenient for offshore transportation and installation, reducing construction costs.

The flexible design can adapt to changes in seabed topography, has excellent seismic resistance, and reduces the risk of rupture caused by ocean currents or earthquakes.

4. Long life and low maintenance

The service life in the marine environment can reach more than 50 years, far exceeding traditional steel pipes (usually need to be replaced every 15-20 years).

Almost maintenance-free, greatly reducing the total life cycle cost (TCO).

5. Environmentally friendly and safe

Non-toxic, will not pollute the marine ecological environment.

Recyclable, in line with the requirements of sustainable development of the ocean.

 

Main applications of HDPE pipes in marine engineering

1. Seawater transportation system

Seawater desalination plant intake and drainage pipes: corrosion-resistant, suitable for high-pressure seawater transportation in reverse osmosis (RO) systems.

Marine aquaculture water supply pipes: used for deep-water cages and land-based recirculating aquaculture (RAS) systems.

2. Submarine pipeline and cable protection

Submarine water pipes: used for island freshwater supply or domestic water transportation on offshore platforms.

Cable protection sleeves: protect submarine optical fibers and power cables from mechanical damage and corrosion.

3. Marine oil and gas and new energy projects

Oil field injection pipes: transport seawater for oil layer pressurization, replacing carbon steel + anti-corrosion coating solutions.

Offshore wind power pile foundation protection: as an anti-corrosion sleeve, protect steel piles from seawater erosion.

4. Marine environmental protection and dredging projects

Tailing deep-sea discharge pipes: used for the discharge of submarine mining waste, wear-resistant and leak-proof.

Dredge sludge conveying pipes: ultra-high wear-resistant HDPE (such as UHMWPE) is used for mud transportation with high sand content.

5. Floating structures and dock facilities

Floating breakwater connection pipe: flexible connection to adapt to wave movement.

Dock water supply and fire fighting system: resistant to salt spray corrosion, long-term reliable operation.

 

Successful Cases

1. Middle East Seawater Desalination Project

DN1200 HDPE pipes are used to transport high-pressure seawater to the reverse osmosis system, replacing the original glass fiber reinforced plastic (FRP) pipes.

8 years of operation without corrosion and leakage, maintenance costs reduced by 60%.

2. Norwegian offshore wind power pile foundation protection

HDPE casing protects steel piles from corrosion by high-salinity seawater in the North Sea, with a design life of 50 years.

 

HDPE pipes are becoming the preferred solution to replace traditional metal pipes in marine engineering with their unique corrosion resistance, lightweight and long life advantages. With the development of materials science and marine engineering technology, the application potential of HDPE in deep-sea energy, ecological protection and other fields will be further released, providing reliable support for sustainable marine development.
