Desalination - Viking Johnson

Desalination plants play a critical role in supplying potable water to regions facing increasing water scarcity, converting seawater into freshwater through processes such as reverse osmosis.

These facilities operate under demanding conditions, with high salinity, pressure and temperature creating a highly aggressive environment for pipeline infrastructure. As a result, the specification of pipe materials and fittings is fundamental to ensuring long-term reliability and operational efficiency.

Key Desalination Challenges

One of the Primary Challenges within Desalination Systems is Corrosion

Seawater contains high levels of chlorides and dissolved gases, which accelerate material degradation and increase the risk of:

Pitting

Crevice Corrosion

Stress Corrosion Cracking

To combat this, pipelines are typically manufactured from corrosion-resistant materials such as duplex or super duplex stainless steels.

These materials help maintain system integrity under high pressure and extend asset life, reducing maintenance requirements and lifecycle costs.

Pipe Fittings must be Suitable for High Pressure Systems

High-pressure systems – often operating at up to 70 bar – require robust, leak-tight joints capable of withstanding continuous stress, movement and vibration. Thermal expansion and pipeline movement further reinforce the need for flexible and secure jointing solutions.

Złączki mechaniczne mają kluczowe znaczenie

Mechanical fittings, such as couplings and flange adaptors, play a critical role in addressing these challenges. Viking Johnson design and manufacture a range of mechanical jointing solutions that support efficient and reliable pipeline operation across water treatment and desalination applications.

Their fittings are engineered to

Accommodate pipe movement

Reduce stress concentrations

Simplify installation

Enable ongoing maintenance without extensive system disruption

Adelaide Desalination Plant in South Australia

A notable example is Viking Johnson’s involvement in the Adelaide Desalination Plant in South Australia.

Working with SA Water and contractor McConnell Dowell, Viking Johnson supplied large diameter flange adaptors (DN1600) for the project’s transfer pipeline infrastructure. This large-scale scheme delivers significant volumes of potable water from seawater, supported by extensive trunk mains connecting the plant to the wider network.

The use of large diameter mechanical fittings provided secure connections, installation flexibility and long-term reliability across critical pipeline sections.
