【Ten Years of Rapid Development in Chemical Processing Equipment】Domestic production of scraper flowmeters for large-diameter crude oil pipelines from 1075 to 2023
Thread Content
Ten years of rapid development in chemical technology – praise for China’s prosperity and strength. This is just a starting point; more participation from everyone will make things even more lively. HaiChuan becomes even better with your involvement; we welcome everyone to take an active part in the forum discussions. It’s hot in July, so be careful to prevent fires. --------------------------------------------- At present, the large-diameter imported flow meters used by **Pipeline Group for measuring crude oil transactions have been in service for a long time and are about to require bulk replacement. New crude oil pipeline projects also generate a high demand for large-diameter scraper flow meters. To reduce dependence on imported equipment and lower construction and operation costs, it is imperative to develop domestically produced large-diameter crude oil pipeline scraper flow meters. On June 16, 2023, the scientific and technological project on the development and application of scraper flow meters for domestic large-diameter crude oil pipelines, undertaken by the Eastern Storage and Transportation Company of the Pipeline Network Group, passed the acceptance review conducted by the Group’s Science and Technology Department. A total of 2 invention patents and 1 practical new patent have been applied for in this project, with 100% of the intellectual property rights belonging to **Pipeline Group. In November 2022, the scraper flowmeter for large-diameter domestic crude oil pipelines developed under this project received a certification of domestic origin from the China Machinery Industry Federation. This marks another key piece of equipment for oil and gas pipelines being manufactured domestically, effectively reducing the costs associated with pipeline construction and operation.
In July 2021, the scientific and technological project on the development and application of scraper flow meters for crude oil pipelines was approved by the Technology Department of **Pipeline Network Group. Eastern Storage and Transportation Company assigned nearly 20 technical experts from fields such as production and supply to form a project team responsible for researching this project. The main research contents of this project include the preparation of technical specifications, drawing design and prototype manufacturing, testing of the prototype’s functions and performance, industrial trials, and evaluation for domestic production. Through scientific research and innovation, the project team overcame key technical challenges such as the cam design for scraper flow meters, the selection of materials for the scrapers, and the design of both mechanical and electronic display units. As a result, the scraper flow meters developed independently achieved higher accuracy and repeatability, as well as an improved range ratio. They also featured dual display units and dual pulse output functions, eliminating signal errors caused by reverse rotation or vibration of the flow meters and thus meeting the requirements for precise measurement.
The scraper flow meter developed by Dongbu Storage and Transportation Company has a diameter of 300 millimeters, a pressure rating of 5.0 MPa, and a range ratio of 5:1; its technical specifications such as accuracy and repeatability are superior to those of the imported flow meters currently in use. The selling price of this flow meter is only one-fourth that of imported flow meters of the same model, and its delivery time is 6 months shorter compared to imported flow meters. During the project development, a total of 4 scraper flowmeter prototypes were manufactured. Two of these were sent for third-party testing at the National Institute of Metrology in China and at the **Petroleum and Natural Gas High-Flow Metering Station, while the other two were installed at the Yangzi Station in the Yangzi Operation Area in Nanjing and at the Dongying Station of the Shandong Provincial Company for industrial testing. On June 27, 2022, the prototype of the scraper flowmeter completed over 10,000 hours of industrial testing; the results showed stable performance, meeting the requirements for industrial use.
