The E for DI pipe is 24,000,000 psi and just 400,000 psi for PVC. With DI pipe being 60-times STIFFER than PVC, the DI pipe can obviously carry greater loads directly, thereby passing less of the loading off to the bedding. chillifrog recruitment

The purpose of bedding is not to provide additional soil capacity but rather to insure the pipe is well supported, and to tranfer the load to the bottom of the trench as a relatively uniform load. This prevents damage to the pipe due ... chilli food recipes
