New welding technology to help the Central Asian Pipeline "accelerate"

 Central Asian natural gas pipeline project pipeline up to 1801 km, since August 8 this year, sparking open welding has, in Kazakhstan has been rapidly advancing the construction of 500 km. Yesterday morning, in Almaty, Kazakhstan, Central Asia, China Petroleum Pipeline Bureau, the total pipeline welding division Jin Red Star introduced to ensure that this pipeline for 30 years safe in the pipeline's construction of the building, they are in the traditional "semi-automatic welding cellulosic electrodes plus" technology, the innovation of "semi-automatic welding in welding plus" technology, welding is 1.5 times the original schedule, while reducing the labor intensity of 1.5 times and construction costs.

   Uniform welding standards

     Central Asian natural gas pipeline from Turkmenistan and Uzbekistan from the border of Baghdad Naim, via Uzbekistan, Kazakhstan, and finally to our country's Horgos connected with the Second West-East. Transit countries of Kazakhstan and Uzbekistan are involved in this long-distance pipeline construction.

     Early in the project, the first star placed in front of Jin's contradiction is that the Kazakh state with two black state in welding and welding inspection personnel to follow the standard construction is still in Russia in 1989 to develop standards, and the present welding and global testing standards is the latest version of the American Petroleum Institute API1104 welding specifications, has achieved great technical leap.

     To ensure quality, increase weld schedule, repeated and Kazakh star Jin, Wu countries one by one against the standard of welding experts to communicate, and ultimately make them acceptable to use the latest version of the global welding and testing standards.

   Accelerate the progress of welding

    With the unification of welding technology and testing standards, but more fully in the project to promote efficient welding technology. After several experiments, the technical staff from the traditional "semi-automatic welding cellulosic electrodes plus" technology, and innovation and a "semi-automatic welding in welding plus" technology. The process by China Petroleum Pipeline Bureau expert seminar.

    Pipeline construction in Central Asia came in handy in the process, the progress of welding proven traditional technology is 1.5 times the original. Central Asia pipeline diameter of 1067 mm, 1 km long pipeline with 85 pipe to be welded, just 10 hours to complete, fully automated welding machine with similar speed, but an automatic welding machine than 1 year unit to save $ 22 million; and the original old technology can only be done half a kilometer, while saving 30% than the traditional craft of welding consumables, which means savings of 30% of the equipment and human resources.
