The development of steam traps in China started relatively late compared with foreign advanced countries. In China, medium and low pressure steam traps are mainly produced, with low parameters, poor performance, short service life and poor test methods. Only a few manufacturers have performance test devices for products below medium pressure, Some steam trap manufacturers even leave the factory without testing, resulting in serious steam leakage.

At present, with the rapid development of information technology, the steam trap is used as the executive mechanism of steam pipeline to remove condensate. If the modern computer technology, sensing technology, network and remote control technology and intelligent technology can be embedded in the steam trap products to control the opening and closing of the steam trap, the new steam trap designed according to this idea has been reported abroad. In terms of production and demand of steam traps, there is a big gap between China and foreign countries. Take Japan as an example, Japan and China have similar energy consumption (nearly 1 billion tons of standard coal in China and 500 million tons of standard coal in Japan). The annual output of steam traps in Japan is 3.1 million, each with a service life of more than one year, a steam leakage rate of less than 3%, and a steam pipe network and thermal efficiency of more than 50%; In China, the annual output of steam traps is about 2.2 million, with an average life of less than one year. Generally, the steam leakage rate is about 6%, and the heat dissipation efficiency of steam pipes is about 30%. At present, China's steam traps can not meet the needs of the domestic market in terms of output, quality and product varieties. At the same time, there is a big gap in the variety series of high parameter products.

Based on the current situation of steam trap industry, industry experts put forward new technology development ideas, that is, humanization, application of new materials, realization of mechatronics. High efficiency, energy saving and green environmental protection are the main direction of China's national economic development in the future. With the large-scale development of electric power (power, thermal power, hydropower, wind power), petrochemical and metallurgical equipment, the requirements for steam traps are also increased. The working pressure of steam traps is required to reach 15.0mpa or higher, and the nominal size is up to dn 150 mm or larger.

Therefore, in the development of new steam trap products, we should consider people-oriented and establish a humanized product design concept; New materials will be continuously applied to steam trap products; Integrating information technology and artificial intelligence technology into steam trap to realize Mechatronics is a new way of technological innovation. There are many kinds of steam traps with great differences. The market demand is constantly changing. The production scale and technical level of steam trap manufacturers are uneven. However, the general development trend and technical approaches of steam trap have many things in common. As long as the steam trap manufacturers can effectively and clearly understand the current situation of the industry, We should constantly optimize our products, strengthen the sense of crisis, and strengthen the corporate culture and market service concept. Only when we strive for speed in stability, perfection in speed, and stability in precision, can we enable enterprises to survive and develop in the increasingly competitive industry tide.
