A few days ago, the world's largest 22000-ton hydraulic press has been successfully developed in Shandong Hengtong Expansion Joint Manufacturing Co., Ltd., and successfully processed a batch of expansion joints and other products for major petrochemical equipment. The hydraulic press has a total investment of more than 0.13 billion yuan and is equipped with 6 hydraulic cylinders with a diameter of 1250mm. It adopts full digital control and can be used to process transition sections, cones and cold deformation of plates with a thickness of less than 400mm in addition to pressing ultra-large expansion joints. The maximum thickness of the processing expansion joint reaches 70mm and the maximum diameter is 6 meters. The birth of the oil press will significantly enhance China's petrochemical and coal chemical industry and other major equipment.

The birth of the oil press will significantly enhance the processing and manufacturing capacity of China's petrochemical and coal chemical industry and other major equipment, and accelerate the pace of revitalizing the localization of major equipment manufacturing industry. At present, the expansion joints and pressure vessels produced by the oil press have been widely used in the domestic petrochemical and coal chemical industries, and have been supporting the development of major petrochemical equipment for many times. For example, the expansion joint developed by the company for the vinyl acetate reactor of Yanshan Petrochemical's major domestic equipment and the acrylonitrile reactor of Jilin Petrochemical Company has a thickness of 40-50mm, and the whole is molded at one time, and all indexes meet the design requirements.

According to introduction, the presses used in the forging industry are divided into two types: water press and oil press. Large presses over 10000 tons are necessary for processing high-end large castings and forgings in nuclear power, petrochemical, coal chemical, hydropower, thermal power, shipbuilding, metallurgy and other industries as well as national defense equipment. At present, the international forging industry only the United States, Japan and Russia can develop more than 10000 tons of hydraulic press, the maximum output pressure is not more than 18000 tons. On December 30, 2006, China First Heavy Machinery Group Corporation designed and manufactured the world's largest and most technologically advanced 15000-ton heavy-duty free forging hydraulic press successfully in a test run, marking the development level of my country's large-scale hydraulic press. Enter the international leading ranks. The successful development of the 22000-ton hydraulic press means a new leap in my country's major equipment processing and manufacturing capabilities.
