Independent development of energy equipment must avoid industrial convergence

at the China (International) energy equipment industry development summit forum held on September 1, Sui Yongbin, President of China General Machinery Industry Association, said that in some equipment fields that have completed localization and formed mass production capacity, the problem of overcapacity has initially emerged and is expanding. He said that energy equipment enterprises should broaden their thinking and avoid industrial convergence

overcapacity leads to disorderly competition

in recent years, China has made significant progress in the localization of energy equipment, breaking the monopoly of foreign companies, making great contributions to reducing project costs for domestic users, and becoming an important driving force to support the sustainable development of the equipment manufacturing industry: 600000 kW supercritical, 1million kw ultra supercritical, and Three Gorges hydropower units The localization rate of key projects such as UHV transmission engineering equipment has reached more than 80%. However, in Sui Yongbin's view, while developing rapidly, some equipment industries may encounter the problem of overcapacity

according to him, in 2009, China's thermal power installed capacity reached 652million kW, accounting for 74.6% of the country's total installed capacity, a year-on-year decrease of 1.45 percentage points. Although the power installation plan in 2020 is not yet clear, it is expected that the new installed capacity of thermal power will be less than 300million kW. Even considering the transformation of old units and the pressure from large to small, its growth space is also very limited. He concluded that the three power plants and other small and medium-sized power generation equipment enterprises may have excess production capacity in supercritical and ultra supercritical thermal power units

similar to conventional power supply, the nuclear power market with the highest technical threshold is facing the same problem

according to Sui Yongbin, the state has established three major nuclear power equipment manufacturing bases in Northeast China, Shanghai and Sichuan according to the plan. The nuclear island large castings and forgings and pressure of megawatt nuclear power will be a larger SUV type Bev container, main pipeline, nuclear grade pump valve, lifting ring and other key equipment, which will initially form a production capacity and present a moderately competitive market pattern. Among them, the production capacity of pressure vessels in 2009 was 7 sets, and it is expected to reach 12 sets in 2012; The industry of in reactor testing machine has developed for several decades in China. The production capacity of components and control rod drive mechanisms was 4.5 sets in 2009 and will reach 7 sets in 2012; The capacity of nuclear island main pumps was 3 sets in 2009, and will reach 18 sets in 2012; The capacity of turbine generators in the conventional island was 8 sets in 2009, and it is expected to reach 15 sets in 2012

the current potential production capacity has been able to win in the market, and can meet the needs of nuclear power development planning and export. It is not suitable to build new nuclear power equipment bases, but there are still repeated investments and herd around. Suiyongbin said that only in the second-generation improved nuclear power pump and valve market, more than a dozen enterprises have formed production capacity and began to compete for prices

Sui Yongbin said that at present, domestic manufacturing enterprises have begun to compete to reduce prices, and some enterprises even hesitate to compete at a price lower than the cost. In the long run, it is not desirable for manufacturing enterprises or the safety of major strategic projects of the country. We can imagine that if an enterprise provides equipment to the country at a loss for a long time, there will be a great potential safety hazard

the three parties work together to avoid industrial convergence

for the problem of overcapacity, Sui Yongbin suggested that energy equipment enterprises should make full use of existing scientific research achievements, actively seek new development ideas, and avoid the convergence of the whole industry

at present, gas steam combined cycle, 600000-1000000 kW air cooling units, supercritical and ultra supercritical thermal power unit pumps and other related equipment, industrial steam turbines and electric actuating machinery supporting auxiliary equipment still need to rely heavily on imports; Although the automation control system and key automation instruments have made some progress in the field of million KW thermal power, they have not played a major role in general; In addition, the supply of high-quality small and medium-sized castings and forgings is seriously insufficient, which has become a bottleneck in the development of nuclear power and conventional thermal power products; Petrochemical hydrogenation valves and thermal power high parameter valves rely on imports for 90%. Suiyongbin believes that in the next 10 years, advanced energy equipment will still be the main driving force to support the development of equipment manufacturing industry. There is still great resistance in the localization of the above equipment fields, which is also the focus of future market development. Therefore, the majority of energy equipment manufacturing enterprises should devote more energy to it

however, Sui Yongbin said that it is not enough to rely solely on the self-discipline and efforts of the enterprise itself. It is also necessary to continue to adhere to the selection of appropriate measurement organization and coordination by the relevant government departments. He hoped that the relevant national departments and local governments could seriously study and formulate some guiding policies, coupled with the support and cooperation of users. Only with the joint efforts of the three parties can we do a good job in localization and actively and steadily promote localization
