The Industry Challenge:
Growth of corrosion-induced or manufacturing cracks in liquid pipelines occurs due to fluctuations in the internal pressure. Operators must estimate the rate of crack growth to determine the remaining service life of the pipe and when the pipe must be repaired.
How We Help:
C-FER’s cyclic pressure cell imposes rapid pressure cycles on large-scale pipe specimens so that many years of in-service pressure cycles are simulated in a matter of hours.
Field specimens of pipe with cracks are tested to determine how the cracks grow with pressure cycling to allow Operators to estimate crack growth during operating conditions.
The data is also used to benchmark crack growth models to help estimate crack growth rates in pipeline systems where crack growth rate data is not available.
