The material properties of Fusible PVC® and Bell & Spigot PVC are identical with the exception of material weight and the type of restraints. Bell & Spigot PVC provides a slightly higher material weight due to the bell end of the pipe. In addition, Fusible PVC® is fully restrained, meaning no fittings are required, whereas bell restraint harnesses are required for Bell & Spigot PVC. The drawings below more clearly illustrates these material properties:
|Fusible PVC®||Bell & Spigot PVC|
|Dimension Ratio||Pressure Rating||Dimension Ratio||Pressure Rating|
|DR 18||235 PSI||DR 18||235 PSI|
|DR 21||200 PSI||DR 21||200 PSI|
|DR 25||165 PSI||DR 25||165 PSI|
|DR 32.5||125 PSI||DR 32.5||125 PSI|

|DR 51||80 PSI||DR 51||80 PSI|
Fusible PVC® will require a more narrow trench width for direct bury than Bell & Spigot PVC, due to the larger outer diameter on the Bell & Spigot PVC. A smaller trench volume means that there will be less excavatopm, less backfilling and less spoil disposal. The drawing below illustrates theses advantages.
Fusible PVC® is fully restrained, so no restraint hardware is required. In addition to a larger Outer Diameter, Bell and Spigot PVC requires restraints at each joint, causing in upsize in casing for Jack & Bore. The comparisons below illustrate these significant differences.
