Oil and gas still account for about 75% of the United Kingdom’s energy requirements. As such, it is still a huge component of the UK economy. Even electricity generated at power plants, for better or worse, requires the combustion of natural gas to get the dynamos spinning.

Although production of oil by UK companies has been decreasing linearly with time since its peak in 1999, we still produce over a million barrels of oil per day. The extraction of hydrocarbons has ever been a high-capital business and requires ultra-modern, sophisticated machinery and materials.

Such machinery often includes high-pressure parts moving over one another. A hard anodic coating will reduce the rate of abrasion on such aluminium components. Thus HA can be used to maximise the lifespan of oil and gas machinery. An alternative way of preventing wear is by increasing lubricity. Hard Anodising Ltd can treat aluminium alloys and other base materials to increase lubricity. In the case of hard anodising, Anolube (PTFE) impregnation works as a kind of semi-permanent lubricant retained in the film. If the base material is not aluminium, an ENP coating containing PTFE has a <0.1 CoF (EN Vs EN) - ask for NiKlad ICE Ultra. The materials used in these machines are also likely to find themselves immersed in high or low pH environments, such as seawater (>7 pH) or near combusting hydrocarbons (low pH).

Hard, chromic, and standard anodising helps protect against both, as does electroless nickel plating.

For corrosion resistance on materials which are not aluminium alloys, high-phosphorous ENP provides excellent protection.

An example of high pH anodising used in this industry is in turbines, which measure the flow of crude oil. The flow of oil rotates the turbines, which have magnets at their outer diameter; the electrical current induced gives information about the flow rate inside the tube. The pH of crude oil is approximately 10. Such conditions would require the aluminium turbine to be sulphuric or chromic acid anodised.

We are a dedicated provider of specialist metal finishing services, concentrating primarily on the anodising of aluminium.
