Technical FAQs
PVC pipe works great for conveying water and sewage. PVC pipe may be exposed to various chemicals via direct contact with soil contamination or via chemicals in the fluids inside the pipe. The concentration of the chemical is important when considering chemical resistance.
- For a list of chemicals to which PVC Pipe is resistant refer to the table in Plastics Pipe Institute's Technical Report: TR-19 Chemical Resistance of Thermoplastics Piping Materials.
- For general Chemical resistivity of typical gasket material used with PVC pipe see the chart below:
General Resistivity of Typical Gasket Materials
