According to the report of the United States transportation department, mechanical damage is one of the most important reasons for the pipeline accident .The most typical form of mechanical damage is indentation. Dent defect is one of the important factors affecting pipeline fatigue life, and it will greatly reduce the fatigue life of the pipeline in service. Meanwhile the dent displacement wil...

Safe pipeline transportation of energy resources is a major concern for the public. Since a pipeline has been built and buried, geologic hazards, corrosions and third-party damages all pose cumulative internal and environmental risks to the pipeline’s integrity. As today’s pipeline engineering and operation become more reliant on geospatial data for safety in the pipeline’s life cycle of design...

The combination of hardware acceleration and flexibility make FPGAs important to image processing applications. There is also a need for efficient, flexible hardware/software codesign environments that can balance the benefits and costs of using FPGAs. Image processing applications often consist of a pipeline of components where each component applies a different processing algorithm. Component...

In order to improve the administrative level of pipeline safety among the surrounding environment, this paper proposes a pipeline risk assessment system of space and visualization based on the current situation of the gas pipeline risk assessment. The database of pipeline surrounding natural environment and social environment are established by using GIS. And the scatter grams on the accident s...

steel pipelines are susceptible to corrosion by the action of corrosive substance in the environment and one of the most common failure modes in buried pipeline coatingis cathodic disbondment. consequently, electrochemical impedance spectroscopy (eis) was used to assess the effect of three important parameters, the thickness of coating, the artificial defect and electrolyte type, on cathodic di...
