Successful Delivery of Interzone 485 Coated Steel Pipe Piles

We are pleased to announce the successful delivery of a batch of ASTM A252 steel pipe piles for a significant crude oil wharf project. To ensure the long-term durability and protection of these piles in harsh marine environments, we selected Interzone 485 from the AkzoNobel International Protective Coatings range.

This coating provides a robust defense against the corrosive effects of saltwater and other environmental stressors, ensuring that the steel pipe piles remain structurally sound and maintain their performance over time. With this reliable protective solution, we are confident that the piles will contribute to the crude oil wharf’s long-term operational success, minimizing maintenance costs and ensuring operational safety.

Steel pipe piles are critical in constructing and stabilizing oil jetties, wharves, and terminals. Their primary purposes include:

1. Yapısal destek

Steel pipe piles serve as the structure’s main vertical load-bearing foundation elements. They transfer the loads from the wharf or terminal to deeper, more stable layers of soil or rock beneath the seabed. This is particularly important in areas with weak or soft soil conditions common in marine environments.

2. Resistance to Marine Corrosion

Given their exposure to seawater, steel pipe piles must be highly resistant to corrosion. Specialized coatings (like Interzone 485) and material treatments protect the piles from the aggressive marine environment, ensuring they last for decades despite constant exposure to saltwater, moisture, and tidal forces.

3. Zorlu Koşullarda Dayanıklılık

Oil jetties and terminals are often subjected to dynamic forces from ship docking, wave action, and wind. Steel pipe piles provide the necessary strength and flexibility to resist these forces without compromising the structure’s integrity. Their ability to withstand the shock loading from large vessels docking or departing is essential.

4. Anchoring for Docking Facilities

At oil jetties, steel pipe piles are used to anchor docking systems for tankers and cargo vessels. These piles ensure that the structures remain securely in place, even during the loading or unloading process, which can involve significant weights and forces.

5. Çevresel koruma

The piles help to create stable foundations for the oil terminal’s infrastructure, such as storage tanks, transfer pipelines, and access walkways. This ensures the safety of operations and minimizes the risk of oil spills or leaks by maintaining structural integrity even during extreme weather conditions or seismic activity.

6. Cost-Effectiveness and Versatility

Steel pipe piles are cost-effective compared to other deep foundation systems, especially for marine environments. They are also versatile, as they can be used for both temporary and permanent solutions, with the ability to be driven deep into the seabed to reach a stable substrate.

7. Installation in Deep or Shifting Soils

In cases where the soil near the surface is unsuitable for direct foundation support (such as soft silt or loose sand), steel pipe piles can be driven to greater depths to ensure the wharf or terminal is anchored on more stable ground. Their ability to be installed in deep or shifting soils makes them ideal for marine construction projects.

8. Sustainability and Longevity

With the right protection and maintenance, steel pipe piles have a long service life, ensuring the terminal’s or wharf’s long-term sustainability. This reduces the need for frequent maintenance or repairs, making them a more efficient and environmentally friendly option.

Product Description

An ultra-high build, high volume solids, two component catalyzed epoxy, capable of being applied up to 3000 microns (120 mils) dry film thickness, and providing excellent impact resistance, abrasion resistance and adhesion properties. Suitable for Application using standard airless spray equipment, economical to apply. Excellent resistance to alkalis, chemicals and petroleum products.

Intended Uses

It is a coating for protecting steelwork in severe environments where high abrasion and corrosion resistance is required, including splash zone areas on offshore oil and gas platforms, wharf piles, ship loading facilities, jetties, decks, bridges, chemical plants, pulp and paper mills, and water treatment plants.

Interzone 485 is particularly suitable for use on heliports, work areas, and walkways on offshore structures. It is particularly suitable when used in conjunction with appropriate aggregate to provide a tough, durable, non-slip deck system.

Excellent resistance to cathodic disbondment makes Interzone 485 compatible with both sacrificial anode and impressed current systems. It is particularly suitable for the long-term protection of subsea structures or as a shop or field-applied coating for hot, cathodically protected oil or gas pipelines.

As a tank lining for abrasive slurry e.g. CIL/CIP tanks in the gold mining industry.

Yüzey hazırlığı

All surfaces to be coated should be clean, dry and free from contamination. Prior to paint application, all surfaces should be assessed and treated in accordance with ISO 8504:2000.

For immersion service, Interzone 485 must be applied to surfaces blast-cleaned to Sa2½ (ISO 8501-1:2007) or SSPC-SP10. However, for atmospheric exposure, it may be applied to surfaces prepared to a minimum of Sa2½ (ISO 8501-1:2007) or SSPC-SP6.

Surface defects revealed by the blast cleaning process should be ground, filled, or treated appropriately.

The surface profile must be a minimum of 50 microns (2 mils).

Interzone 485 can be applied over Interline 982. The primer surface should be dry and free from all contamination, and Interzone 485 must be applied within the specified overcoating intervals (consult the relevant product datasheet).

As we continue to deliver high-quality solutions for critical infrastructure projects, this successful completion marks another important milestone in our commitment to excellence in engineering and material protection.
