How do i resist corrosion in my pipe line project? Any special recommendations?

I'll give you some simple solutions to resist corrosion (not to prevent) Design Do’s & Don’ts Avoid excessive mechanical stresses and stress concentrations in components exposed to corrosive mediums.
Esp when using materials susceptible to SCC.
Avoid galvanic contact / electrical contact between dissimilar metals to prevent galvanic corrosion.
Avoid sharp bends in piping systems when high velocities and/or solid in suspension are involved – erosion corrosion.
Avoid crevices – e.g weld rather than rivet tanks and other containers, proper trimming of gasket, etc.
Avoid sharp corners – paint tends to be thinner at sharp corners and often starts to fail.
Provide for easy drainage – avoid remaining liquids collect at bottom.
E.g steel is resistant against concentrated sulfuric acid.
But if remaining liquid is exposed to air, acid tend to absorb moisture, resulting in dilution and rapid attack occurs.
Avoid hot spots during heat transfer operations – localized heating and high corrosion rates.
Hot spots also tend to produce stresses – SCC failures.
Design to exclude air – except for active-passive metals and alloys, they require O2 for protective films.
Most general rule : AVOID HETEROGENEITY

the most common protection methids in pipeline and piping are:

1- Cathodic Protection.

2- Galvanization.

3- Painting.

4- Selecing for high corrosion resistance Metals (Stainless steel, duplex & Ni Base Alloys)

and generally we merge between1 &3 to reduce cost

You may consider getting Carbon Steel Pipes Coated using FBE Coatings.
Pipes coated with FBE may last more than30 Years.
