Measured Load Capacity of Buried Reinforced Concrete Pipes ...

Jan 14, 2016  Reinforced concrete pipes are normally tested using a three edge bearing test and the critical load for design is the applied load required to create a 0.254 mm (0.01 in.) crack in the pipe, since it is believed that wider cracks will lead to premature deterioration as water is allowed to reach the reinforcement and induce corrosion.

Prestressed Concrete Pipe - an overview ScienceDirect Topics

Prestressed concrete pressure pipes are covered by BS EN 639 and BS EN 642. The nominal size range is from DN 200 to 4000 and is the design internal diameter. American Standards AWWA C301-92 and C304-92 also cover large diameters. Examples of such pipe are typically DN 4000 up to 20 bar and DN 3600 up to 26 bar for North Africa.
