Field Joining Methods
4 MethodsCommon methods used to assemble and joint this pipe material in industrial & commercial service:
- Solvent cement (ASTM D2855)
- Threaded — Schedule 80 only (50% pressure de-rate)
- Flanged (Van Stone / full-face)
- Gasketed bell-and-spigot (large diameter)
Temperature De-rating
Factor CurveBase pressure rating at 73 °F (23 °C) is multiplied by the de-rating factor:
Water, non-shock. Factors per Spears Manufacturing PVC/CPVC de-rating table; verify with the pipe manufacturer.
Chemical Compatibility
Ambient Temp- Dilute acidsGood
- Concentrated / oxidizing acidsLimited
- Alkalis (bases)Good
- Salt solutionsGood
- Oxidizers (bleach, peroxide)Good
- Alcohols / glycolsGood
- Aliphatic hydrocarbonsLimited
- Aromatic / chlorinated solventsNot recommended
General class-level guidance. Always verify against specific fluid concentrations and elevated operating temperatures.
Dimensions are nominal values for preliminary sizing. Verify against the current edition of the cited standard and the manufacturer’s product data before use. Dimensions per ASTM D1785; properties are typical for uPVC (PVC Type I).
