Jinling Branch of Sinopec Co., Ltd. and Jinling Petrochemical Co., Ltd. of Sinopec Group are collectively known as Jinling Petrochemical. The company was established in 1982. mainly engaged in oil refining and the processing, production and sales of petrochemical products. Its main business of oil refining can be traced back to the 1950s, and it is a national "first five year plan" key project. The company is the third largest crude oil processing base and clean gasoline and aviation coal production enterprise in China, as well as the detergent raw material production base in Asia. The company has a comprehensive crude oil processing capacity of 18 million tons / year, with more than 60 sets of advanced production units such as oil refining, aromatics, thermoelectricity, alkylbenzene, etc. the main units adopt the world's advanced and mature technology and control technology, and the technical and economic indicators have reached the domestic and international advanced level in an all-round way, occupying an important position in the petrochemical industry layout in East China and riverside areas.

　　Sinier sd43 wedge flowmeter has been widely used in Jinling Petrochemical Company. The heavy oil measurement of Jinling Petrochemical Company has always been a difficult problem. In the past, the equipment used was leaking due to the blockage of the impulse pipe and the wear of the measuring pipe, and the average service life was less than 1 year.

　　Because of its special structure, Wedge Flowmeter is mostly used in medium with high viscosity and low Reynolds number. The above photo is the occasion for Jinling Petrochemical Company to measure heavy oil on site. The medium temperature of the station is very high (above 400 ℃), the pressure is high (10MPa), there are many impurities and particles, and the dynamic viscosity is very large. High temperature and high pressure design is adopted for the measuring tube of sinier sd43 Wedge Flowmeter. The flange grade is strictly in accordance with GB high pressure flange standard. In view of the situation that there are many impurities and particles, the sintering tungsten carbide process is adopted for the inner wall of the measuring tube and throttling element of sd43. effectively eliminating the impact of impurities abrasion on it, and greatly extending the service life of the instrument. In terms of pressure tapping technology, Φ 22 large diameter impulse pipe or DN50 flange pressure tapping is adopted to ensure that the impulse pipe will not be blocked. The equipment has been in stable operation for nearly 3 years and has been highly praised on site.
