Latest hydraulic press news

Recently, the world's largest 22,000 tons hydraulic press has been successfully developed in Shandong Hengtong Expansion Joint Manufacturing Co., Ltd., and successfully produced a number of expansion joints and other products for the petrochemical major equipment.

 

The hydraulic press has a total investment of more than 130 million yuan and is equipped with 6 hydraulic cylinders with a diameter of 1250 mm. It is fully digitally controlled and can be used to process transition sections, cones and thicknesses in addition to super-large expansion joints. The sheet within a millimeter is cold deformed. The processing expansion joint has a maximum thickness of 70 mm and a maximum diameter of 6 m. The birth of the hydraulic press will significantly enhance the processing and manufacturing capabilities of major equipment such as petrochemicals and coal chemical industry in China, and accelerate the pace of localization of major equipment manufacturing. At present, the expansion joints and pressure vessels produced by the hydraulic press have been widely used in the domestic petrochemical and coal chemical industries, and have been used for the development of major petrochemical equipment. For example, the company is an expansion joint developed by Yanshan Petrochemical's major domestically produced equipment vinyl acetate reactor and Jilin Petrochemical acrylonitrile reactor. The thickness is 40-50 mm, and the whole molding takes place. All the indexes meet the design requirements.

 

According to reports, the presses used in the forging industry are divided into two types: hydraulic presses and hydraulic presses. Large-scale presses of over 10,000 tons are high-end large-scale castings and forgings in the fields of nuclear power, petrochemical, coal chemical, hydropower, thermal power, shipbuilding, metallurgy and other industries. Major equipment required. At present, only the United States, Japan and Russia can develop more than 10,000 tons of hydraulic presses in the international forging industry, and their maximum output pressure does not exceed 18,000 tons. On December 30, 2006, China's No.1 Heavy Machinery Group Co., Ltd. designed and manufactured the world's largest and most advanced 15,000-ton heavy-duty free forging hydraulic press, which successfully marked the development of China's large-scale hydraulic press. Ranks. The successful development of the 22,000-ton hydraulic press means a new leap in China's major equipment processing and manufacturing capabilities.
