China Petroleum and Natural Gas Pipeline Science Research Institute Co., Ltd. (hereinafter referred to as the "Research Institute") was established in 1984. It is a professional institution engaged in scientific and technological research, equipment product manufacturing and technical services in the field of oil and gas pipelines. The institute currently has 205 personnel, including 16 doctoral and postdoctoral students, 93 masters, 39 with associate vocational and above, and 92 intermediate professional titles; 3 company-level technical experts of the Group, 3 chief technical experts of the Pipeline Bureau, and 3 pipelines There are 8 technical experts in the bureau and 3 senior skill experts.

The institute has professional research institutes such as material and storage and transportation safety, corrosion protection, welding, construction equipment, non-excavation, testing, and standard information, and has an industrial center, responsible for the manufacturing and promotion of scientific research products. It has the "National Engineering Laboratory for Oil and Gas Pipeline Transportation Safety", "Failure Analysis Branch of the Chinese Mechanical Society" and "Quality Supervision Center". Carry out scientific research, product manufacturing and technical services around pipeline construction and safe operation of in-service pipelines.

In terms of scientific research, we have successively completed the research on the "Study on the on-site welding process and comprehensive evaluation technology of ring welds", "Study on high-precision automatic welding over-generation detection (AUT) detection technology and equipment", and "Study on the laser composite welding technology and equipment 》 represented hundreds of scientific research projects such as national 863, national scientific and technological support, Chinese Academy of Engineering, and PetroChina major scientific and technological special projects, and won many national, provincial and ministerial honors and awards.

In terms of product manufacturing, the CPP900 series automatic welding complete sets, mechanized replenishment complete sets, AUT detection equipment, DR digital ray detection equipment, large torque power reaming drilling tools, solvent-free polyurethane coatings, low-temperature replenishment coatings and other domestic advanced domestically Level of equipment and products have been successively used in major domestic and foreign oil and gas pipeline projects such as the West-East Gas Pipeline, Shaanxi-Beijing Line, China-Myanmar Pipeline, China-Russia East-West Gas Pipeline, India East-West Gas Pipeline, Central Asia Pipeline and other major domestic and foreign oil and gas pipeline projects.

In terms of technical services, it undertakes the evaluation of welding, anti-corrosion and testing processes for major domestic and foreign projects; evaluation of cathode protection, corrosion evaluation and pipeline repair in service pipelines; evaluation of oil and gas pipeline safety evaluation and life evaluation; monitoring and analysis of pipeline non-excavation construction; steel pipes , monitoring and manufacturing of bent pipes, pipe fittings and anti-corrosion materials and product performance inspection and testing; information retrieval and analysis, standard formulation (revision), project consultation; training and evidence collection for operators such as welding, anti-corrosion, and inspection, ensuring the safe operation of the pipeline.

The institute takes it as its mission to ensure the technical support of the pipeline industry chain, solve urgent, difficult and dangerous problems in the pipeline field, and take on the technological progress of the pipeline industry, strive for excellence and repay the society with advanced technology.
