Project Overview

 

This project is part of the Saudi Red Sea mega development project in Saudi Arabia, one of the world's largest sustainable tourism and infrastructure developments located along the Red Sea coastline.

The desalination system in this project operates in an extremely high salinity marine environment, where chloride concentration is significantly higher than standard seawater conditions.

To ensure long-term durability and system reliability, the project required ASTM A409 super austenitic stainless steel pipes with 32" large diameter design for the high-salinity desalination pipeline system.
