I am putting together a design spec for a saltwater system that includes plastic tubing and was wondering if there is any information on what the maximum flow velocities are for such tubing? The tubing within the system is teflon PFA, PEEK, and polyethylene varying in size from 1/16" to 1/4"; I have experience with metal piping in saltwater systems and know that piping like 90-10,70-30, and Ti have flow velocity limits to prevent excessive corrosion and erosion but is there a similar standard for plastic tubing?
