Shandong's state-owned companies try to combine production, education and research
Excavator pipe fittings and tube fittings are essential components in the hydraulic system of excavators. These fittings are used to connect hydraulic hoses and tubes to various components of the excavator, such as the hydraulic pump, cylinders, and valves.

They are justified in saying so. According to statistics from the Shandong Provincial Economic and Trade Commission, in the first quarter of this year, there were 307 high-tech chemical companies in Shandong Province. The output value of high-tech products was 39 billion yuan, and the export value of high-tech products reached 3.6 billion yuan. Key chemical companies such as Shandong Dongyue Group, Shandong Binhua Group, and Chengshan Group have established close cooperative relationships with a number of well-known domestic and foreign academies and universities. They have built technology development centers with universities and research institutes. It is this model. The large number of key technological innovations that have been developed have achieved the status of the largest chemical province in Shandong.
"The enterprise is the main body of technological innovation, but if the two wings of universities and research institutes are missing, this subject will not fly," said Miao Shengrong, deputy general manager of Yankuang Guotai Chemical Co., Ltd.
Miao said that last year, the daily processing of 1000 tons of coal-based new-type gasifiers and supporting an annual output of 240,000 tons of methanol and 200,000 tons of acetic acid plant was completed and put into operation in Yantai Cathay Pacific. This is a new multi-cogeneration project for deep processing of coal from mine pits to downstream chemical products. It is a large number of high-tech products with independent intellectual property rights that have supported this project. Among them, the new coal-water slurry gasification technology jointly developed by Yankuang Group, East China University of Science and Technology, and China Tianchen Chemical Engineering Co., Ltd., the clean coal gas power generation and methanol cogeneration technologies jointly developed by Yankuang Group and the Institute of Engineering Thermophysics, Chinese Academy of Sciences Key technologies. "If you let companies develop these technologies alone, they will not be able to say a great deal and the time will not be enough." Miao Shengrong said.
Dr. Feng Xijin, director of the post-doctoral research station at Triangle Group, was deeply impressed by this. He told reporters that the rapid development of the automotive industry, the increasing demand for tires, in the past people only sought high-speed tires and wear-resistant, but now it requires tires at the same time comfortable, stable and safe. However, as a tire manufacturer, they do not know much about the performance of the car. In order to solve this problem, they carried out special research on the matching of car tires with Tsinghua University Automotive College, solved the technical problems of the matching performance of automobile tires, and improved their products to match the capabilities of car factories. During the “10th Five-Year Plan†period, they were able to complete the research and development of more than 120 varieties of radial tires in 60 series of cars, light trucks, and trucks, especially UHP high-performance passenger car radial tires, off-road lighter radial tires, and white tire side series. Products also benefit from the solution of this key technology.
Lubei Chemical Co., Ltd. is a key chemical company in Shandong. Last year, its sales revenue reached 6.45 billion yuan, and profits and taxes were 970 million yuan. It was ranked as the second best fertilizer manufacturer in China by the National Bureau of Statistics. Lu Hongxuan, deputy general manager of Lubei Chemical, told reporters that these achievements have benefited from the combination of production, education and research. He said that Lubei Chemical has now established three circular economy industrial chains with independent intellectual property rights: ammonium phosphate, sulfuric acid, cement cogeneration, seawater and water use, clean power generation and salt production. "The key technologies in this area are solved through the combination of production, education and research."
“For Shandong chemical companies, the joint efforts of industry, universities, and research institutes solve not only new technology issues, but also play a significant role in the digestion and absorption of imported technologies,†said a person in charge of Shandong Chemical Industry Office.
Wang Fucheng, director of the strategic development department of Yantai Wanhua Polyurethane Co., Ltd., told the reporter that in the 1970s, they introduced an MDI device with an annual output of 7,000 tons from Japan. At that time, only production licenses were obtained, core technologies were not available, and production was intermittent for 10 years. They hope that Japanese companies can transfer technology, but they have been rejected. Later, they cooperated with the Qingdao Institute of Chemical Technology and other institutions, and on the basis of digesting the MDI technology introduced from Japan, they independently developed MDI manufacturing technology with independent intellectual property rights in 2000. At the end of last year, this independent construction The annual output of 160,000 tons of MDI equipment was successfully put into production.
There are various types of excavator pipe fittings and tube fittings, including:
1. Flanges: Flanges are used to connect two pipes or tubes together. They are usually bolted together and provide a leak-free seal.
2. Adapters: Adapters are used to connect two different types of fittings or components. They can be male or female, and can be used to connect hoses, tubes, or other components.
3. Elbows: Elbows are used to change the direction of a pipe or tube. They come in various angles, such as 45 degrees or 90 degrees.
4. Tees: Tees are used to connect three pipes or tubes together. They come in various configurations, such as equal tees or reducing tees.
5. Couplings: Couplings are used to connect two pipes or tubes together. They can be either rigid or flexible, and are often used in tight spaces where movement is limited.
Excavator pipe fittings and tube fittings are made from various materials, including steel, brass, and aluminum. The choice of material depends on the application and the environment in which the excavator is used. For example, steel fittings are often used in high-pressure applications, while brass fittings are used in low-pressure applications.
Overall, excavator pipe fittings and tube fittings are critical components in the hydraulic system of excavators. They ensure that hydraulic fluid flows smoothly and efficiently through the system, enabling the excavator to perform its tasks effectively.
