Corrosion Resistant Coatings for Marine Environments

Mining equipment suffering from rust and corrosion

Corrosion can be a big problem for parts and machinery operating in marine environments. Mild steel is commonly used for marine applications due to its strength, ease of fabrication and relatively cheap price.

The only problem is, it corrodes very easily when exposed to seawater. So when mild steel isn’t protected by a corrosion resistant layer or barrier, it quickly loses its strength and can, therefore, result in failure of parts.

What is Corrosion?

Corrosion is the gradual destruction of materials by chemical reaction with their environment. It is the oxidisation of the metal at the interface between the metal and the environment, and the reaction results in the degradation of the mechanical properties of the metal. Corrosion is dependent on many factors, including oxygen concentration, pH, water temperature and the presence of dissolved salts such as chloride, sulphate and sulphites.

Pitting Corrosion

Pitting corrosion is a type of corrosion that occurs on mild steel in a localised fashion. The steel penetration can be very deep in relation to the area under attack, and it is therefore one of the most dangerous types of corrosion.

Bacterial Corrosion

Bacterial corrosion can also be referred to as micro-biological corrosion or anaerobic (without oxygen) corrosion. This type of corrosion is likely to happen if the environment that the metal is exposed to supports bacterial activity. For bacterial corrosion to occur, there must be stagnant water, a hydrocarbon food source e.g. oil or coatings, the presence of sulphates, an operating temperature of between 20 – 40C, and the presence of bacteria.

Corrosion Prevention Using Metal Coatings

The prevention of corrosion requires the elimination or suppression of the chemical reaction between the environment and the metal. One way of preventing this reaction is by applying a metal coating to the surface of the substrate, and the effectiveness of the coating depends on factors including the type of coating used, the operating environment and the coating type.

SeaTEC 100 Marine Corrosion Protection

Here at NiTEC, we have developed a corrosion resistant metal coating that effectively protects mild steel from salt spray corrosion and marine corrosion for an extensive period of time. For more information about SeaTEC 100 and its ability to extend the life of parts exposed to subsea conditions, please contact the expert team at NiTEC by calling 0845 224 3571 or email us at web@nitec-enp.co.uk.

Long Lasting Oil and Gas Components for Subsea Applications

Oil and gas components are exposed to harsh environments, both under the sea and underground. This exposure to such extreme levels of temperature, moisture and pressure can have a detrimental effect on these components in a short space of time.

Corrosion protection in Sub-Sea Environments

As specialists in the electroless nickel plating process, Nitec have worked tirelessly on developing the latest technology in corrosion resistant marine coatings.

 

Our specialists have developed and tested this revolutionary product, and we consider the coating to be a market leader within our industry.

SeaTEC 100 is our very own development and the perfect solution for corrosion protection and corrosion prevention in sub-sea environments. Not only will it protect mild steel from salt spray corrosion and marine corrosion for an unprecedented amount of time, SeaTEC effectively coats valves, pumps and pipe fittings to ensure that they remain intact and in operation.

Features of SeaTEC 100 Marine Corrosion Resistance

SeaTEC 100 effectively plates metal components, valves and connectors, making it a very cost effective way of extending the life of mild steel operating in subsea, marine environments.

This coating is great for increasing the strength of components. Materials tend to be at their weakest levels in areas where they have joins; therefore, components such as pipeline connectors are often vulnerable to corrosion. Corrosion at vital points such as these can mean failure of a system, so their longevity is essential to the overall lifespan of the system as a whole.

The Ideal Plating for Oil Rigs and Gas Pipes

SeaTEC 100 has also been through an extensive, independent testing process which has confirmed that the coating can withstand salt spray conditions for over 25,000 hours. This period of time is actually unprecedented in the industry, making SeaTEC100 a leading coating. This ability to extend the life of materials such as mild steel in marine environments means the downtime as a result of corroded parts is reduced or eliminated, saving money and time.

If you are looking for a metal coating that provides high levels of corrosion resistance for use in the oil or gas industries, call the NiTEC team on 0845 224 3571, email info@nitec-enp.co.uk or get in touch via our contact page.

NiTEC’s Marine Coating Technology

NiTEC’s very own marine corrosion prevention technology, SeaTEC 100, is the ultimate solution to increasing the life of components used in subsea conditions.

SeaTEC 100’s superior marine corrosion resistance means that mild steel is protected from salt spray corrosion and marine corrosion for extensive periods of time, making it perfect for use on offshore platforms such as oil rigs.

Marine Corrosion Protection

SeaTEC 100 is an extremely cost effective coating.

Because it extends the life of materials in marine environments, such as mild steel, the downtime that would usually be caused by repair or replacement of corroded parts is reduced, or even avoided altogether.

This makes SeaTEC 100 an ideal plating for oil rigs and pipes used to transport oil and gas.

Features of SeaTEC 100

  • Effectively plates metal components, valves and connectors, making SeaTEC 100 a cost-effective way of extending the life of mild-steel operating in marine environments, the ultimate in marine corrosion prevention.
  • Effectively increases the strength of items such as pipeline connectors, where the material is at it’s weakest level.
  • SeaTEC 100 has been independently tested to withstand salt spray conditions and protect against marine corrosion for over 25,000 hours, a period of time that is unprecedented within the metal plating industry.
  • It is available in a range of colours.
