Steel for water, desalination and utility projects

Saudi Arabia operates one of the largest desalination sectors in the world and extensive water transmission networks connecting coastal plants to inland cities.

Industry context

These assets face aggressive chloride exposure and demand careful material selection, coatings and corrosion protection.

Key considerations

  • Chloride resistance and coating systems
  • Cathodic protection compatibility
  • Potable water approvals for linings
  • Specifications of the relevant water authority

Transmission pipe

Large diameter welded steel pipe with internal lining and external coating.

Storage

Steel tanks for potable, raw and fire water storage.

Corrosion-resistant metals

316L, duplex and super duplex for seawater and brine service.

Questions to settle before you buy

  • Is the water seawater, brine, raw or potable?
  • Which coating and lining standard applies?
  • Is stainless or duplex required?
  • Which authority specification applies?

FAQs

Which stainless grade suits seawater?
Standard 316L can pit in seawater; duplex 2205 and super duplex grades are commonly selected for seawater and brine service, subject to engineering review.
How are steel water pipes protected?
Typically with internal linings (e.g., cement mortar or epoxy), external coatings (e.g., 3LPE or FBE) and cathodic protection for buried lines.
