Expansion Epoxy-Based Fittings for RTRC Rigid Nonmetallic Conduit

NEMA BI 50071-2009 (S2025) | Status: Active | ID: 100445

All construction materials expand and contract with fluctuations in temperature.  These temperature changes affect Reinforced Thermosetting Resin Conduit (RTRC) differently than other common materials such as steel or PVC. For example, the coefficient of thermal expansion for RTRC (1.5 ×10-5 in./in./ºF or 2.7×10-5 cm/cm /ºC) is slightly more than twice that of steel and is 50% that of PVC
