Air separation equipment is a kind of equipment which can separate air and produce high purity oxygen, nitrogen, argon and other gases through certain technology. Air separation equipment is widely used in various fields of national economy and is one of the core equipment in the industrial field. The downstream of air separation plant is mainly metallurgy, chemical fertilizer, coal chemical industry and other industries.
Hangzhou oxygen Co., Ltd. is mainly engaged in the manufacturing of air separation equipment and the operation of industrial gas, which is the absolute leader of China's air separation equipment manufacturing industry. The company's main products are used in metallurgy, chemical fertilizer, petrochemical, coal chemical industry, aerospace and other industries, providing high-quality complete sets of air separation equipment for downstream customers. The downstream of industrial gas mainly includes steel, chemistry, non-ferrous metals, electronics and other industries. Relying on its advantages in the field of equipment manufacturing, the company cuts into the industrial gas industry and provides downstream customers with oxygen, nitrogen, CO2 and a variety of special gases necessary for the production and processing process
In addition, hang Yang also manages the production and sales of large-scale ethylene cold box, vacuum storage tank, gas filter, various turbine compressors, natural gas compressors, centrifugal liquid pumps and other equipment, as well as EPC and other fields, and has made good achievements. In the past few years, affected by the capacity reduction of iron and steel, chemical industry and other industries, the company's equipment manufacturing business has declined. During the same period, the scale of industrial gas business gradually expanded, the production and operation became more and more mature, and the operating revenue and net profit kept increasing year on year. In the first half of 2016, hang Yang achieved an operating revenue of 2.199 billion yuan and a net profit of - 56 million yuan.
Hangzhou oxygen products are mainly large complete sets of air separation equipment. This kind of equipment uses the technology of low-temperature rectification separation to separate the air, and then produce high-purity oxygen, nitrogen, argon and other gases. It is mainly used in the basic industries of national economy such as chemical industry, industrial gas, metallurgy, electric power and so on, which use a large amount of oxygen or nitrogen. It is an important supporting equipment for the above industrial devices.
At present, the company has achieved a breakthrough of 80000 m3 / h, 100000 m3 / h to 120000 m3 / h in the field of air separation equipment design and manufacturing, and further enhanced its market influence and competitiveness in the field of large and extra large air separation equipment. At the same time, with the successful development of the high-pressure and low-pressure integrated plate fin heat exchanger, the successful operation of the high-pressure process pump, and the successful start-up of the hydrogen expander, the company also made great progress in the research and development of the key components and core technologies supporting the air separation equipment.
