CO2 transport pipelines, as a critical link in CCUS technology, are more prone to fracture propagation under the effects of environment and high pressure due to the special characteristics of CO2, resulting in ductile fracture incidents. However, the commonly used original Batelle two curves method (BTCM) has large errors applied to CO2 pipelines containing impurities. In this paper, a corrected BTCM based on a hoop stress calibration factor was proposed to evaluate the crack arrest ability of CO2 pipelines. The reliability of the modified model was verified based on the experiments data. The results show that the GERG-2008 equation of state is more suitable in predication of decompression wave velocity, and fracture propagation velocity model with a correction factor of ccf =2.0 was verified in quite good agreement with experiment results. This corrected BTCM that can be directly applied to engineering, provided theoretical basis and suggestions in the design and safe operation of CO2 pipelines containing impurities.

CO2 pipeline transportation is the most economical and efficient way to realize CCUS (Carbon Capture, Utilization and Storage) technology, but there is a risk of ductile fracture during its operation due to engineering problems such as pipeline defects, fatigue and corrosion. In this study, a modified Battelle Two-Curve Model and a crack arrest performance evaluation model based on the crack arrest efficiency were established for the pipeline overall reinforcement structure and coaxial crack arrestor, respectively, and the models were verified experimentally to be reliable. Based on the supercritical CO2 pipeline transportation scheme designed for Yanchang Oilfield with storage capability of 4 million t/a, the crack arrest performance of five pipelines was evaluated. For the non-crackable pipelines, the pipeline overall reinforcement and the coaxial crack arrestor are applied, based on the crack arrest requirement and engineering economy, respectively. This study provides references and suggestions for the design and safe operation of supercritical CO2 pipelines containing impurities in the future.

“…Thanks to the ease of transportation and assembly on existing pipelines, Clock Springs are especially suitable as repair systems and crack stoppers. Moreover, since their application does not require an interruption in the pipeline service, they offer an adequate solution for those cases where operative pressure reduction is not feasible or allowable [13].…”

One of the major challenges in the design of ultra high grade (X100) gas pipelines is the identification of areliable crack propagation strategy. Recent research results have shown that the newly developed highstrength and large diameter gas pipelines, when operated at severe conditions, may not be able to arrest arunning ductile crack through pipe material properties. Hence, the use of crack arrestors is required in thedesign of safe and reliable pipeline systems.A conventional crack arrestor can be a high toughness pipe insert, or a local joint with higher wall thickness.According to experimental results of full-scale burst tests, composite crack arrestors are one of the mostpromising technologies. Such crack arrestors are made of fibre reinforced plastics which provide the pipewith an additional hoop constraint. In this paper, the material selection, testing and modelling for the designof composite crack arrestors is presented.First, an overview of the most commonly used (integral and non-integral) crack arrestors is given, indicatingthat fibre reinforced devices are one the most promising solutions to arrest running fractures. Then, materialcharacterization of unidirectional fibre glass reinforced epoxy is addressed to measure the orthotropicproperties of this composite material. Traditional mechanical characterization is compared with a nondestructive testing method to measure the elastic constants of the composite material. In the end,micromechanics of fibre reinforced plastics is applied to predict the material properties. The theoreticalpredictions are compared with experimental values.In an accompanying paper, numerical tools to simulate crack initiation, propagation and arrest for this typeof crack arrestors are introduced. The combination of numerical simulation and experimental researchallows deriving design guidelines for composite crack arrestors.
