Corrosion-resistant pipeline materials for seawater?
Thread Content
:Handshake: I need expert help. Using duplex steel for high-pressure pipes in seawater desalination is quite expensive; considering both cost efficiency and performance, I’m thinking of using 316L pipes with an anti-corrosive coating resistant to seawater corrosion. But I’m not sure which manufacturers can produce such pipes, nor what the material of the anti-corrosive coating should be Please ask an expert for help!

The title of the post should reflect its main content.
What is the maximum pipe diameter for a person to enter and apply the coating?
To the friend on the 3rd floor: The high-pressure pipelines of the first-stage RO desalination system use pipes with diameters ranging from φ76 to φ273, and the material is 316L.
Valves with a full lining should not present any problems, right? I’ve worked on a seawater desalination project before, and in those projects the materials used were either stainless steel or those with linings.
