RE: Code Velocity Maximums Plastic Pipe Materials

ASME B31.3 Section VII pertains to nonmetallic piping and to piping lined with nonmetals.
Appendix B contains design stresses for various non-metallic piping materials plus an index of the ASTM specs covered by the code. Maybe the individual specs will give you the information you require?
