Project Backgroud

Jubail Desalination Plant is the largest seawater reverse osmosis desalination plant as well as largest green hydrogen production plant in the world(recognized by the Guinness World Records). It is located 18 kilometres south of Jubail Industrial City,Saudi Arabia’s eastern province and will be able to treat over 600,000 cubic metres a day (cm/d) of seawater using reverse osmosis technology. This project is a significant step in meeting the increased demand for water in Saudi Arabia.


Scope of Supply

To serve the demanding desalination industry, AFFCO chose super duplex stainless steel (ASTM A995 Gr 5A) plug valves to withstand seawater corrosion and other intergranular corrosion and pitting. These valves are typically designed with high pressure(CL600) and large size (DN0800) for control and on/off applications. The top entry style allows for a convenient removal and re-installation of plug valves. We are one of the few manufacturers in the market capable of providing such high pressure and large size plug valves. Our solution plays a vital role in protecting pumps, enhancing power generation, and unlock the full potential of the desalination plant,resulting in improved plant efficiency and reliability.

In addition, AFFCO’s plug valves are suitable for other high-pressure membrane treatment applications in highly corrosive environments, including offshore oil and gas sulfate removal systems, industrial water reclamation and reuse facilities, high-purity water treatment for power, and water processing for mining.
