Cathodic protection is adopted for buried steel pipelines

Buried steel pipeline using cathodic protection law pipeline integrity management implementation is inseparable from the ability, and safe and efficient operation of the smart oil and gas pipeline network. Risk assessment, internal and external testing, residual strength evaluation of defects and data points can be expected, intelligent pipeline construction will be a technical means and key technologies such as pipe analysis support. Mode of leap, will eventually change the traditional pipeline design, construction, along with the mobile Internet, Internet of things, cloud computing, artificial intelligence operation management pattern, will greatly improve pipeline data acquisition, the risk rating of a new generation of technology in the field of industrial application has become increasingly mature, China's oil and gas prices and the technology level of prevention and control, defects testing and evaluation, In the process of promoting the large-scale construction of pipeline network, the standardization and module integration management of pipeline business set foot on a new stage.

The level of automation and informatization has been continuously improved, and the "said quantity 1" has been basically realized, which has laid a solid foundation for effectively solving the problems of pipeline integrity management during the construction period. Pipeline integrity management regulations, the Chinese oil group company relying on construction pipeline integrity throughout the east gas pipeline management between China and Russia should feasibility study, preliminary design and construction drawing design, engineering to carry out the "transfer of fully digital, intelligent operation, whole life Zhou Gong, production start-up, completion inspection and acceptance process, The data generated during the pipeline construction period shall be truthfully, timely and completely entered into the data management system according to the requirements of integrity management. Data collected during the construction period include pipeline property data, environmental data, design documents, construction documents and records, evaluation reports, etc. The integrity and accuracy of pipeline basic data are highly correlated with the analysis of pipeline inspection data and risk assessment during the operation period, which directly determines the success or failure of pipeline integrity management in the whole life cycle. In the process of data collection during the construction period, data filling is not timely, incomplete and inaccurate, which directly affects the quality of data collection. At the same time, engineering quality problems are also one of the main risks of pipeline operation, resulting in accidents.
