3. External load design includes calculation of both ring bending stress and deflection. Ring bending stress is limited to 48,000 psi, providing a safety factor of 2.0 based upon minimum ultimate bending stress. 4. Deflection of the pipe ring is limited to a maximum of 3 percent for cement-lined pipe.
