Pipe Stiffness, Ring Stiffness Constant and Flexibility …

Flexible pipe deflection depends on the coined contribution of its pipe stiffness and the eedment soil stiffness (E''), but primarily on eedment soil stiffness. Considerable testing and field measurements have established that for low stiffness pipes, deflection is almost exclusively controlled by the eedment soil surrounding the pipe.
