Hang oxygen, thousand hammer

- Jan 14, 2019-

If you want to do it, you will do 6 sets of the same as foreign companies. Hangyang needs to compare with them. We must fight for this opportunity and become a place in China for the manufacture of extra large air separation equipment.

——Jiang Ming, Chairman of Hangzhou Hangyang Co., Ltd.

"6 sets from the German giant Linde, have successfully oxygenated, 6 sets of Hang Oxygen from China, the first test drive today. All the experts present in the field of air separation in the field, everyone is looking at the screen, above The real-time data of more than 70 key equipment, the localization of the 100,000-level air separation unit is the dream of China's air separation equipment industry for more than 60 years..."

In March 2018, CCTV's "Daguo Heavy Apparatus" feature film reviewed the grand scene of the construction of Shenhua Ning coal 100,000-level air separation equipment developed by Hangzhou Hangyang Co., Ltd., and devoted it to the ten-year-old Hangyang people. Again, I am filled with emotions.


Since the beginning of the 1950s, Hangyang has gone through the road of introducing foreign technology, independent development and innovation. Facing the unpredictable market environment, the company has been relentlessly consolidating its main business, dedicating to technological innovation and enhancing the core competitiveness of the market. Now it has played a triumphant battle for the Chinese equipment manufacturing industry on the world stage. .

Behind the "Great Powers" is the belief of independent innovation

China consumes about 6 trillion kWh of electricity every year, and about 60 percent of it comes from coal-fired power generation. On the Gobi wasteland in Ningdong, Ningxia, the largest single coal liquefaction base in the world has settled here. Shenhua Ning Coal This set of 4 million tons/year coal indirect liquefaction (commonly known as coal to oil) project, tens of thousands of tons of coal gasification and reliquefaction every day, into more than 10,000 tons of oil liquid fuel, supply to the market.

The core equipment for the front-end process of coal-to-oil conversion providing 12 sets of 100,000-class air separation plants for the production of large quantities of oxygen for this coal-to-oilproject, is the largest air separation cluster in the world, producing 120 per hour. More than 10,000 cubic meters of oxygen is enough to fill 1.4 "Beijing Water Cube" venues. Six of the 12 sets of air separation equipment are from Hangzhou. They are independently developed and manufactured by Hangzhou Hangyang Co., Ltd., breaking the monopoly of foreign companies on 100,000-class air separation equipment. From pre-research in 2008 to completion and acceptance in 2017, this decade of coagulation and oxygen have accumulated the unremitting efforts of Hangyang people.

As early as 2004, the National Development and Reform Commission approved the construction of the coal indirect liquefaction demonstration project of Shenhua Ningmei Group, and the required 100,000-class air separation equipment also began to be tendered globally. Although Hangyang has become a leader in the manufacture of air separation equipment in China, it cannot compete with the "world giants" regardless of its performance or company size.

"China's air separation equipment manufacturing has been lagging behind abroad. Although we have been catching up, foreign companies always press us." Mao Shaorong, the general manager of the company, is filled with emotion: "The Shenhua Ning coal project has given a rare opportunity to localize major equipment. If you miss it, our catch-up goal will be even more out of reach."

In the last investigation before Shenhuan Ning Coal's bidding, in order to support the domestic equipment considerations, it was proposed to take 2 sets of 12 sets of equipment for Hangyang. For Shenhua Ningmei, this is the safest solution. Even if it fails, it will not affect the whole.

"When you want to do it, you will do 6 sets of the same as foreign companies. Hanging oxygen should be better than them." Jiang Ming, chairman of the company, has a clear attitude. "We must fight for this opportunity. This is not only an opportunity for Hangyang. It is also an opportunity for China's air-fraction manufacturing industry. It has become a place for China's manufacturing of large-scale air separation equipment manufacturing."

Opened the Design, Supply and Service Contract for Air Separation Units of 4 million tons/year coal indirect liquefaction project of Shenhua Ning Coal. The requirements of the densely packed, almost every requirement are very demanding, and the amount of compensation is much higher than the industry standard. "The general manager of the sales center, Wu Qiaoxian, has been intensively negotiating for 17 consecutive days for 17 days, and his eyes are still arguing.

On April 26, 2013, Hangyang signed a contract with Shenhua Ningmei, and finally won six sets of design, supply and service contracts for 100,000 class air separation equipment.

For this day's arrival, Hangyang prepared for ten years. From concept design, to core unit machine R&D innovation, from automatic control to manufacturing process technology upgrade, constantly modifying the program and improving parameters, Hangyang has been working hard to produce more competitive products. The hard work of several generations of Hangyang people has ushered in today's achievements. This time, the success of oxygen generation marks the entry of Hangyang's air separation technology into the international leading ranks, which is another important milestone in the history of China's air separation development.

Breaking the monopoly into the whole world, because of the unyielding persistence

Quality is the life of manufacturing, and this is the firm belief of Hangyang. The 100,000-class air separation equipment is required to be manufactured on-site in Ningxia due to its large size, but the harsh environment will only worsen. In order to adapt to the low temperature of less than 100 degrees in the air separation equipment, the material is mostly aluminum alloy, but the requirements of the aluminum alloy for the welding environment are extremely demanding, and the huge temperature difference between day and night and the sudden strong wind on the project site will cause adverse effects.

"We can only work overtime when the weather is good, but also to create quality products, so that on-site manufacturing can also meet the same standards as factory manufacturing." Deputy General Manager Zhao Dawei said.

On March 15, 2017, Hangyang's first set of 100,000-level air separation successfully produced oxygen. Real-time data shows that the purity of oxygen reaches 99.87%, which exceeds the industry standard of 99.6%, the purity of nitrogen reaches 99.999%, and the system runs stably.

Over the years, Hangyang has implemented strict pre-, post-, and post-event management, continuously promoted the construction of quality system, effectively guaranteed product quality, and obtained Zhejiang Provincial Government Quality Award and Zhejiang Manufacturingcertification. The advent of six sets of 100,000-level air separation equipment broke the situation of foreign monopoly and wrote a great deal for the localization of major equipment in China.

In the past five years, Hangyang completed industrial investment of 2.75 billion yuan, invested 320 million yuan in technological transformation, and completed about 200 projects. In the past five years, R&D investment totaled 772 million yuan, and R&D investment accounted for 4% of sales. - Between 5%; as of the end of last year, there were 223 authorized patents, including 66 invention patents, participated in the formulation of 32 national standards, and seized the commanding heights of competition... These figures are all behind the technology of Hangyang Co., Ltd. Innovation is highly valued and countless times of innovative practice and exploration.

In 2010, Hangyang Co., Ltd. was successfully listed. The company invested all the funds raised in equipment renewal, technological transformation and gas project development. It has no hesitation and dedication to adhere to the main battlefield of manufacturing.

From "raising cows to selling cows" to "leading cows to sell milk", extending the industrial chain to the next level

In 2009, Hangyang completed a historic relocation and the equipment manufacturing capability has taken a new step. At the new starting point of enterprise development, Hangyang proposed a development strategy of focusing on two ends, expanding horizontal and making quality products.

The strategy of heavy two endsmeans that the air separation equipment industry will extend to both ends, develop the complete set of business operations, and develop the gas business downwards, eventually forming a development pattern in which equipment manufacturing and gas industry promote each other and develop together. Up to now, Hangyang has invested in 27 gas companies nationwide, and the gas products produced have successfully produced rare gases in addition to conventional gases. At present, gas sales have exceeded 50% of the company's total revenue, and profits accounted for 70% of total profits. The employees of the company proudly said that in the past, they only "raised cows to sell cows. Today they not only sell cows, but also bring cows to sell milk."

In addition, Hangyang also set up an engineering company to focus on air separation and industrial gas engineering design, which not only ensures the construction quality and cycle, but also effectively controls the construction cost and ensures the safe and reliable operation of air separation equipment. "Becoming a world-class air separation equipment and gas operation expert is our unswerving goal." Jiang Ming said firmly.www.wxytgas.com
