Is their a USCG approved plastic pipe or C-PVC that is available for accomondation pressure piping and/or black water piping? The application would be used on cargo vessels, freshwater. The product would have been ran thorugh a series of tests such as a fire endurance,smoke, and flame spread test. Any ideas or ideas would be appreciated.
