Industries

Cathodic Protection systems are routinely installed on structures in the following sectors.

HIGHWAYS & CIVIL ENGINEERING

Reinforced concrete structures are generally very durable structures. However, if contamination from chlorides occurs or the concrete becomes carbonated then corrosion of the reinforcing steel may take place.

Bridges, other highway structures and multi-storey car parks can all suffer from chloride contamination arising from de-icing salts.

Corrosion Prevention Limited can assess structures for corrosion risk, undertake investigative and quantitative surveys. If required, we can then design and specify repair and protection systems, including concrete repairs systems, galvanic anode systems or impressed current cathodic protection systems.

BUILDINGS

Reinforcement in concrete frames and concrete cladding panels can deteriorate due to carbonation of the surrounding concrete, or as a result of contamination due to windblown chlorides or cast-in chloride set accelerators.

Masonry clad steel frames, and in particular those from the early 20th century, are susceptible to corrosion, as a result of porous cladding materials, porous mortars and detailing that enables water saturation of the frame.

Corrosion Prevention Limited can assess structures for corrosion risk, and undertake investigative and quantitative surveys. We can then conduct feasibility studies and trial installations of prospective systems, and design and specify the appropriate corrosion management solution.

PORTS, HARBOURS & TERMINALS

Accelerated Low Water Corrosion (ALWC) is a widespread phenomenon that can result in rapid section loss of both sheet steel and tubular steel sections at the lower tidal levels.

Steel structures that are buried, immersed or exposed to the air in a marine environment may also require corrosion protection measures.

Corrosion Prevention Limited has extensive experience of designing cathodic protection systems to combat ALWC, for both existing and new structures. Such systems may be galvanic anodes or impressed current systems, and we can offer advice on the most suitable solution.

In addition to the deterioration of steel structures, reinforced concrete marine structures such as jetties and wharves, marine bridges and tunnels can all suffer from corrosion damage arising from chloride ingress due to their location.

OIL & GAS

Buried metallic structures, such as pipelines, tank bottoms and well casings are all susceptible to corrosion. The importance of this infrastructure and the potential risks of corrosion damage mean that corrosion prevention measures are of critical importance. The appropriate cathodic protection solution, often used in combination with coatings, can help to ensure the integrity of these structures.

Corrosion Prevention Limited can undertake surveys to assess the level of corrosion likely in different ground conditions, and design and specify cathodic protection systems, including galvanic and impressed current systems.

We can offer system audit and advice on specialised surveys for pipeline cathodic protection systems.
