Pvc Expansion Joint Underground at Finn Shapiro blog

Pvc Expansion Joint Underground. Designed to compensate for length changes due to temperature variations in exposed conduit runs. Table 352.44 and table 355.44 provide the expansion information for polyvinyl chloride (pvc) and for reinforced. In the 2023 nec ®, section 352.44(b) was added which requires expansion fittings to be installed above grade when direct buried pvc conduit emerges from the ground and compensation is needed for earth settling or movement, including frost heave. Expansion joints are used in aboveground installations where temperature changes are anticipated to exceed 25°f (14°c). Underground the temperature remains fairly constant so it's only the exposed section that is going to have much expansion/contraction.
