Before 2015, the domestic economy was still developing vigorously, and the demand for pumps from all walks of life was still strong. Luo Baihui, chief analyst of Jinmou Power Grid, believes that relying on domestic demand, China's pump industry still has room for development.
"Stainless steel pumps have excellent characteristics such as corrosion resistance, high strength, lightness, and long service life. In recent years, stainless steel pumps have been widely used in shipbuilding, rail vehicles and other transportation industries. With the development of machinery manufacturing, stainless steel pumps will have a wider range of Luo Baihui said that from the perspective of consumption, at present, my country's apparent consumption has reached the world's highest level, close to 1/4 of the world's total consumption, and the per capita stainless steel consumption has reached 3.4KG, jumping to a developing country. front row. However, the growth rate of consumption has gradually slowed down, from the ultra-high-speed development stage with an average annual growth rate of more than 30% to the steady development stage with the current growth rate of 6.43%.
Because of its corrosion resistance, high temperature resistance, wear resistance and other characteristics, stainless steel itself will play a more active role in the fields of energy, petrochemical, electric power, mining and other key development in my country. Today, stainless steel pumps are involved in more and more fields, and the demand in the water industry, construction and structure industry, environmental protection industry, and industrial facilities will also increase year by year.
In the water industry, the problem of water pollution during its storage and transportation has been paid more and more attention by people. A large number of practices have proved that stainless steel is an ideal material for water industry such as water preparation, storage, transportation, purification, regeneration, and seawater desalination. Its advantages are: corrosion resistance, shock resistance, water saving, sanitation (no rust and copper green), light weight (1/3 reduction), easy maintenance, long life (can be used for 40 years), low life cycle cost (LCC), It is a green and environmentally friendly material that can be recycled and reused.
    At present, the pipeline in Tokyo, Japan has reached 76% stainless steel, and the leakage rate of the pipeline has dropped from the original 14.7% to the current 7.5%. After the earthquake in Osaka, Japan, the stainless steel water storage tank was intact. Recently, Japan has developed corrugated pipe joints, which can reduce the construction cost of stainless steel water pipelines by 20%, the total cost by 3%, and the maintenance cost by 3/4.
