Recently, the Xinxiang Yalian Heavy Industry Co., Ltd. has announced an exciting news. Their independently designed and constructed 45,000-ton multi-cylinder intelligent linkage press machine successfully completed its first pressure test, achieving the one-time formation of a super-large tonnage and super-large diameter single spherical head. This once again breaks the industry record for the one-time formation of a single large-sized container head with super-large tonnage and diameter in China, adding a rich and significant touch to China's high-end equipment manufacturing.
In the production workshop of Yalian Heavy Industry, this giant press machine is the undisputed star. At the pressure test site, the blank material of the dome was heated to a high temperature, turning red-hot, and precisely placed in the working area of the press machine. As the command was given, the multi-cylinder intelligent linkage system operated stably, applying the powerful pressure in an orderly manner. The blank material gradually took shape during the pressing process. The entire process was carried out smoothly with precise pressure control. Finally, the single spherical dome was perfectly formed in one go, and the on-site technicians and workers witnessed this historic breakthrough together.
Yalu Heavy Industry, as the earliest approved A3 grade spherical shell plate and various pressure vessel head manufacturing professional manufacturer by the State Quality Supervision Administration and the Chemical Equipment Association, this achievement is of great significance. The 45,000-ton multi-cylinder intelligent integrated press machine integrates advanced technologies and overcomes the challenges of forming large-tonnage and large-size heads. The design size of this equipment can meet all head products with a diameter of 8000mm, a thickness of 500mm, and a single-piece weight of less than 150 tons. It fills the domestic equipment and technology gap, breaks the current monopoly of super-large head markets, and enhances China's competitiveness in the manufacturing of high-end head products. The single-piece spherical head is formed in one go, significantly improving production efficiency and product quality, reducing the loss and quality risks of traditional multiple forming processes, and providing more reliable and larger equipment components support for key industries such as petrochemicals, energy and environmental protection, nuclear power, and military industries.
"Though the road ahead is steep and hard as iron, now we stride forward anew." The success of this pressure test is the result of Yalu Heavy Industry's decades-long continuous efforts and unremitting dedication to high-end equipment manufacturing. It showcases the innovative strength of the "Head Covering Capital" industrial cluster in Xinxiang County. In the future, Yalu Heavy Industry will continue to strive, using advanced equipment technology to drive industry upgrading, and help China's high-end manufacturing reach new heights, contributing more to "Made in China".
