What coating protects stainless steel from sulphuric acid?

+++++++

Our customer has stainless steel tubes that are used to process waste water and treat human waste. They will be subject to sulphuric acid and other corrosives. What can I coat the stainless steel tubes with to protect them?

Teflon or plastisol should do it. I rather doubt that a paint or thermoset powder will be impervious enough. Good luck.
