PE pipe grades needed to enhance research and development efforts
Plastic pipe is plastic building materials in the amount of the largest varieties of more products, as a new chemical building materials in China has broad market space. In a wide variety of plastic pipe in, PE pipe for the excellent performance, reasonable price, occupy an important position. Last year, China produced a total of 1.65 million tons plastic pipe, PE pipe accounted for 36%.
At present, China has more than 150 enterprises PE pipe production, annual production capacity of 600,000 tons, of which more than 30 annual production capacity of 5,000 tons. Although China PE pipe processing enterprises have formed a certain scale, but because of long-term existence of identical products, new product development is slow, mainly relied on imports of raw materials, greatly limiting the development of the industry. In fact, whether domestic or foreign, the industry generally believe that, with technological advances and customer demand continues to improve, middle and low pipe market will decline in consumption, production and saturation of the plight of The high-tech, high-performance pipe will eventually become a product of high value-added enterprises, high-margin weapon.
The rapid development of plastic pipe industry, in large measure dependent on material properties and process technology improvements. China PE pipe industry had mainly rely on imported technology, PE pipe Special Materials is largely dependent on imports, but only with the higher cost of production of low-tech Special Material products. However, as domestic users performance requirements on the PE pipe upgrading of domestic enterprises have realized that development of PE pipe PE pipe and Special Materials for high value-added significance for the development of the industry, so in recent years in high-performance PE Pipe and Special Materials R & D have begun to tilt.
First, in high-value-added plastic pipe in the development and processing technology, the Chinese enterprises have made considerable progress. Fujian Asia Pass New Material Technology Co., Ltd. to rely on self-development, so that domestic large-diameter PE pipe technology has been a qualitative leap. The company's gas buried PE pipe with diameter of up to 630 millimeters; PE Pipe diameter of up to 3000 mm, breaking the large-diameter pipe was the monopoly of foreign enterprises. In addition, to extend the life of PE pipe, the sub-pass has also done outstanding work, they found that PE control in blue or black, especially after adding 2% of carbon black to prevent light and UV damage, So that anti-aging products significantly enhanced.
PE pipe floor heating is another high-value areas, but the domestic enterprises in this field have been able to produce medium and low product, the product of identical greatly compressed in the field margins. Beijing Huayuan Chemical Building Materials companies in the Asia-Pacific PE-X pipe floor heating in walking in the front of the domestic counterparts. It is the one of the few in accordance with international testing standards by 8760 hours thermal performance tests to meet international product standards, the useful life of more than 200 years of pipe manufacturers. Domestic enterprises to produce high-grade geothermal pipes, to show that the industry's attention and commitment to the market.
Secondly, in the PE Compound for the area, the domestic enterprises exert themselves up. Special Material for the escalation of international PE pipe, a new generation of high-strength special PE pipe materials continue to emerge, not only there PE80 level, but also appeared PE100 grade. PE pipe materials, upgrading to a variety of stress significantly increased. Because of technical problems, China's high profile Special Materials PE pipes for many years has been dominating the world of foreign products, but also higher prices. The Yangzi Petrochemical bullish this market, working to develop high-performance PE Pipe Compound, and by the industrial test a success. This Pipe Compound bimodal molecular weight distribution, with excellent physical and chemical properties, Basic hot PE100 to meet international standards, so that China raise the level of the PE pipe Compound for a large.
