One of the possible options for protection from the influence of an aggressive environment is the spraying of ceramics or glass-like material.

I use a company called Silcotek to coat ss316 tubing in parts for high corrosion applications.   www.SilcoTek.com  You can visit their website to see if this will work for you.

Hi Mr. Funsho,

It depends on how corrosive the environment is, or future conditions that may produce a highly corrosive environment.

I have been using Teflon® or PTFE-lined piping as the anti-corrosion solution in my line of work, which may or may not be suitable for your application. But you can refer to the PTFE and Teflon Chemical Compatibility Chart in this link.
