A few days ago, under the supervision of the world’s authoritative testing organization, Lloyd’s Register Quality Assurance (LRQA), the super-high-pressure plate-fin heat exchanger designed by Hangyang Plate Heat Exchanger Co., Ltd., completed its final pressure test. The hydrostatic test pressure reached 17.55 MPa, exceeding the highest design pressure level for such products in the world (13.5 MPa), marking a historic breakthrough. The core of this product consists of air channel sections with a design pressure of 0.55 MPa, and liquid nitrogen channel sections with a design pressure as high as 13.5 MPa and a maximum hydrostatic pressure of 17.55 MPa. During the development process over the past two years, the company’s technology innovation team conducted numerous research experiments, strengthened collaboration between industry, academia, and research institutions, achieved innovations and breakthroughs in areas such as material control technology, and obtained multiple invention patents. High-pressure aluminum plate-fin heat exchangers are key components in large-scale air separation equipment. In recent years, Hangyang has overcome 8 technical challenges related to design, manufacturing processes, and quality. By ending the reliance on imported high-pressure plate-fin heat exchangers, it has continued to elevate the performance of such products to new levels. Hangyang achieved a rapid progression in these products, moving from 10MPa to 12.8MPa and then to 13.5MPa, thus transforming from a follower to a leader. Among them, the 12.8MPa grade product won the First Prize of the China Machinery Industry Science and Technology Progress Award in 2021. Hangzhou Oxygen Machine Group Co., Ltd. (hereinafter referred to as Hangyang) was established in 1950 and went public on the Shenzhen Stock Exchange in 2010 (stock code: 002430). It is a world-class supplier of air separation equipment and cryogenic petrochemical equipment, as well as a pioneer and leader in China’s gas industry. Hangyang is the manufacturer of China’s first air separation units; it ranks first in the world in terms of production and sales volume of large and extra-large air separation units. The 100,000-ton class air separation units produced by Shenhua Ningmei are regarded as \"major national assets\", with their overall technology reaching an internationally leading level ； It holds the first market share in China for low-temperature petrochemical products such as ethylene cryogenic tanks, and the project \"Research and Development of Complete Ethylene Production Systems for Complex Raw Materials on a Million-Ton Scale and Their Industrial Application\" won the **First Prize for Scientific and Technological Progress**.
