Central Asia pipeline welding technology innovation break with traditional patterns

 July 20, the reporter learned from the Pipeline Bureau, in the newly completed single-Central Asia pipeline project in the main welding, pipeline Bureau of innovative construction techniques, the use of "semi-automatic welding in welding +" technology to improve the welding speed; implementation of large-scale, integrated mechanized assembly-line nature of the construction unit to play large formation combat advantage, breaking the traditional mode of construction, creating a record number of pipe welding.

    As of July 20, in Uzbekistan and Kazakhstan Pipeline Bureau has completed the A-line body welding 1040 km, B body welding line has completed 460 km in total of the two countries completed the main welding more than 1500 km, and created 800 million man-hours accident-free record.

   Central Asian oil pipeline project is China's biggest ever international pipeline projects. The face of cross-border multi-national construction, the effective duration of only 200 days of difficulty, the pipeline Bureau of well-organized, scientific deployment, break through the traditional mode of construction, so that the whole project as planned steadily.

   In the welding process, the pipe line construction on the Council in addition to the use of CRC automatic welding, the technical staff of the CRC also the world's fastest root welding technology and pipeline Bureau of the most skilled, semi-automatic welding technologies, in the traditional "cellulosic electrode + semi-automatic welding "process, based on the development of" semi-automatic welding in welding + "technology, welding is 1.5 times the original schedule, while reducing the labor intensity of 1.5 times and construction costs.

    In project management, pipeline Bureau emphasized that the design, procurement and construction (EPC) closely co-ordinate arrangements, enhance communication, resource sharing, giving priority to efficiency, the three parties to the relative coordinate, implement EPC minimize costs, maximize efficiency; full use of pipeline Bureau construction advantages, the implementation of large-scale, comprehensive mechanization of assembly-line construction crew to play large formation combat advantage. From the measurement of pay, transport piping, welded topography detected by the recovery process 22 single integrated unit to complete the construction, reducing the working interface, improved work efficiency. Kazakh segment CRC Ma Jingyong automatic welding group, semi-automatic welding in welding + MA Wu welding units were created on 32 km and 28 km of pipeline welding a new record.

    In quality control, pipeline Bureau pioneered the domestic non-destructive testing team lead Ruha Wu countries, the power to make up for the lack of local sub. NDT speed up construction to ensure the smooth progress. March 24, Kazakh Pipeline Bureau, to obtain a non-destructive testing qualification, Kazakh Pipeline Bureau since its independence in non-destructive testing work legally, which is in the Kazakh foreign companies to obtain this qualification the first time in history.

   Currently, A-line natural gas pipeline in Central Asia after the completion of the main welding, pipe work focused Bureau field station installation, plumbing and landscape restoration under the ditch, while efforts to accelerate the B line construction is scheduled to be completed end of September, Kazakhstan, the main section of Line B welding, ensure that this year November 15 and single production line through the end of next year.
