Dalian Jinding Petrochemical Machinery Co., Ltd. has been making pressure vessels since 1987. Its predecessor was named "Jinzhou Petrochemical Machinery Factory". In the 1990s, it was based on the township enterprise property rights system of Jinzhou District, Dalian City. The relevant policies of the reform were approved by governments at all levels, and in December 1998, the "Jinzhou Petrochemical Machinery Plant" was officially renamed "Dalian Jinding Petrochemical Machinery Co., Ltd." and registered with the Dalian Municipal Administration for Industry and Commerce. It has a legal person. Qualified limited liability company.

The company covers an area of ​​135,000 square meters and has a construction area of ​​48,807 square meters . There are more than 500 employees, 35 engineering and technical personnel engaged in pressure vessel work, including 19 high and middle-level engineers and 96 welders with special equipment pressure welding qualification certificates. 459 main equipment, including 2 1500-ton hydraulic presses and 1 2000-ton hydraulic press; 4 20-120mm plate rolling machines; 19 3-75-ton cranes; 4 overall heat treatment equipment; Speit imported from Germany for physical and chemical tests Direct reading spectrometer, complete non-destructive testing equipment, meets the needs of manufacturing and installation.

The company has designed, manufactured and installed capacity of more than 40,000 tons/year. As of now, the company has designed, manufactured and installed more than 1,800 spherical storage tanks of various specifications and models. Products are spread all over the country. In recent years, it has joined the construction of major domestic construction projects such as Sinopec, CNOOC, Shenhua and China, and provided a large number of steel spherical storage tanks. The products are exported to Albania, Indonesia, Syria, Sri Lanka, India, Equatorial Guinea, Iran and other countries.

The production of spherical tank products is relatively high in China, and the product quality reaches the advanced level of similar international products. The volume of spherical tanks is 10 cubic meters to 10,000 cubic meters . The company is also a domestic manufacturer with 10 cubic meters and 10,000 cubic meters of spherical tank manufacturing performance; The thickness of the shell plate is from 12mm-58mm; the mediums are filled with ethylene, propylene, oxygen, nitrogen, liquid ammonia, liquefied petroleum gas, etc.; the material of the ball shell plate is Q245R (0/-20℃), Q345R (0/-20℃), 16MnDR ( -40℃ ), Q370R (-20℃ ), 07MnMoVR (-20℃ ), 07MnNiMoDR ​​(-50℃ ), JFE-HITEN610U2 (-20℃ ), JFE-HITEN610U2L (-50℃ ), 08Ni3DR (-100℃ ) , 15MnNiNbDR (-20℃ ), SA-516Gr70, SA-537CL.2 0 (-20℃ ) Cr18Ni9 (S30408) (-196℃ ), etc., especially in low-temperature ball tanks of ethylene, propylene and high-strength steel, the results are particularly good. Highlights: The company manufactures a total of 797 low-temperature ball tanks with a total of 288,371 tons. It is currently a unit with a large manufacturing performance of low-temperature ball tanks and 3,000 cubic meters of ethylene and propylene ball tanks.
