Re: Paint Pipelines

I would recommend s/s or other material that would be corrosion free and compatible to product. Also recommend using full bore ball valves for the system. Long radius bends are an asset but can use 1.5 ells for pigging. My experience regarding painting or other similar "finished" materials systems is to have deicated pipe lines for each product, if cost effective. This eliminates the need for solvent flushing and drying to guard against cross-contamination.
