聚乙烯(PE)是一种从石油中提炼加工而成的塑料材料。本世纪五十年代以来,随着石油化学工业的飞速发展和石油深加工技术的日趋完善,塑料制品种类多样化,产量迅速增长,逐步发展成为一种新型工程材料。与传统管材相比,使用聚乙烯为原料而制成的管道,具有重量轻、耐腐蚀、阻力小、节约能源、安装简便、造价低等显著优点,受到了管道工程界的青睬。
Polyethylene (PE) is a plastic material that is extracted and processed from petroleum. Since the 1950s, with the rapid development of the petrochemical industry and the perfecting of deep processing technology of petroleum, the variety of plastic products has diversified and the output has been rapidly increasing. It has gradually developed into a new type of engineering material. Compared with the traditional pipe, the pipe made of polyethylene as raw material has the obvious advantages of light weight, corrosion resistance, small resistance, energy saving, easy installation and low cost, and is favored by the pipeline engineering industry.
