Polyurethane Insulated Steel Pipe Looking around the world, the polyurethane industry in Western developed countries has already entered a mature development period and entered the innovative research and development stage. The Asian market is growing rapidly, and many multinational chemical companies have shifted their business focus and R&D centers to Asia and even China. Market The development of the polyurethane market in the Middle East is still in its infancy. In general, due to the rapid development of the national economy in the past decade or so, China's polyurethane industry, including basic raw materials to products and machinery and equipment, has reached considerable scale. The annual output of polyurethane in China is about 10,000 tons, with an output value of about 100 million yuan, which has increased by % and % respectively compared with the 10,000 tons and about 100 million yuan in 2016. The average annual growth rate of output is as high as %, and the average annual growth rate of output value is over %. At present, polyurethane insulation Steel pipes have many Chinese and foreign companies involved in the polyurethane industry. In the past ten years, although China's average annual growth rate of polyurethane has been twice that of D, China's per capita consumption of polyurethane has not yet reached the world average. The annual per capita consumption of MD in China is .kg, while the world average is .kg. Calculated based on per capita D development and polyurethane growth rate, China's polyurethane industry is still in a period of rapid growth. In the future, the development of China's polyurethane industry will be mainly driven by five major factors, namely the total population, the automobile industry, building energy conservation, increasing environmental protection requirements, and the leisure and entertainment industry. During the 11th Five-Year Plan period, China's product consumption will maintain an average annual growth rate of 10%. By then, China will be the world's largest product manufacturing and consumption center.
The domestic iron ore market has stabilized, with transactions Slight improvement. The National Day holiday is less than two weeks away, and some steel companies are more willing to stock up before the holiday. In addition, the iron ore resource inventory in the factories of some steel companies is always at a low level.
