Flexible steel pipebehavior when hydrotested is somewhat different from the behavior ofrigid steel pipes. The layers are un-bonded and upon initial pressurizationundergo a stabilization process referred to as conditioning. After condi-tioning, the pipe is held at the test pressure for a period of time.8.
