China is already the world's largest producer and consumer of construction materials. The output of major building materials such as cement, flat glass, building sanitary ceramics, stone and wall materials has ranked first in the world for many years. At the same time, the quality of building materials continues to improve, energy and raw material consumption are decreasing year by year, various new types of building materials are constantly emerging, building materials products are constantly being upgraded, and the foundation of Cangzhou pipeline equipment manufacturing industry is solid. There are currently more than 3,200 production enterprises, of which 222 are large-scale enterprises (sales income of more than 5 million yuan), with 124,000 employees. The main products are various special steel, stainless steel, carbon steel and other caliber seamless steel pipes, low, medium and high pressure boiler pipes, oil drilling pipes and other steel pipes; various tees, crosses, valves, reducers and other elbow fittings Various stainless steel flanges and forged flanges; various pipe fittings, meters, oil blowout preventers and other pipe fittings; various polyethylene pipes, polypropylene pipes and other plastic pipes, a total of 16 categories, more than 370 varieties, more than 3500 varieties specification. The manufacturing process mainly uses hot-rolled straight seam welding, spiral double-sided submerged arc welding, forging, forging, intermediate frequency pushing, cold forming, hot extrusion, etc.
The maximum processing diameter of the pipeline is 2020 mm. Products are widely used in municipal, petrochemical, west-to-east gas transmission, shipbuilding and nuclear power engineering fields, with an annual designed processing capacity of 25 million tons. In 2010, the industrial added value of enterprises above designated size reached 13 billion yuan, a year-on-year increase of 31.7%, accounting for 16.1% of the total added value of all enterprises above designated size. Cangzhou pipeline equipment manufacturing industry is advancing to the goals of "three uppers" (upscale, upper level, and upper equipment) and "three highs" (high-end, high pressure, and high added value), and strives to promote the pipeline equipment manufacturing capacity to reach 30 million tons. Cangzhou will become a well-known "pipeline equipment manufacturing and R & D base" and "pipeline equipment capital" at home and abroad. The "11th Five-Year Plan" for infrastructure investment has reached the middle of the market. The explosive growth of investment in infrastructure construction such as highways and railways and the steady growth of investment in ordinary civil construction have put the construction industry in an upward boom. At the same time, in the context of building an energy-saving society and the country's ability to strengthen independent innovation, the theme of energy conservation and technological innovation will be a hot topic for the industry.
