Deflection is a decrease in the vertical diameter of a pipe. The value ΔY (%) is the average long-term vertical deflection of the pipe and is the final expected change in vertical diameter divided by the nominal pipe diameter, expressed as a percentage. A flexible pipe changes shape several times during the installation of a pipeline.
