China is already the world's largest producer and consumer of building materials. The output of cement, plate glass, 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 decreased year by year, a variety of new building materials continue to emerge, building materials products continue to upgrade. Cangzhou pipeline equipment manufacturing base thick. The company has more than 3,200 production enterprises, among which 222 enterprises are above scale (sales revenue of more than 5 million yuan), employing 124,000 people. The main products are all kinds of special steel, stainless steel, carbon steel and other seamless steel tubes, low, middle and high pressure boiler tubes, oil drilling tubes and other tubes; All kinds of three-way, four-way, valve, reducing pipe elbow fittings; All kinds of stainless steel flange, forged flange; All kinds of pipe frame, instrument, oil blowout preventer and other pipeline accessories; Various polyethylene pipes, polypropylene pipes and other plastic pipes, a total of 16 categories of more than 370 varieties of more than 3500 specifications. The manufacturing process mainly adopts hot rolling straight seam welding, spiral double-sided submerged arc welding, forging, forging, medium frequency push system, cold forming, hot extrusion and so on. The maximum processing diameter of pipeline is 2020mm. The products are widely used in municipal engineering, petrochemical engineering, west-east gas transmission, shipbuilding and nuclear power engineering, with an annual design and processing capacity of 25 million tons. In 2010, the industrial added value of enterprises above designated size reached 13 billion yuan, up 31.7% year on year, accounting for 16.1% of the added value of all enterprises above designated size. Cangzhou pipeline equipment manufacturing industry is advancing towards the goals of "three high" (upper scale, upper level and upper equipment) and "three high" (high-end, high pressure and high added value), and promoting 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". The construction investment of the "11th Five-Year Plan" has reached the middle stage. The explosive growth of highway, railway and other infrastructure construction investment and the steady growth of ordinary civil construction investment make the construction industry in the boom stage. At the same time, under the background of building an energy-saving society and strengthening the independent innovation capacity of the country, the theme of energy conservation and technological innovation will be the development hot spot of the industry. Plastic pipe fittings and pipes once again set off a pipe fittings boom.
