在管道领域发生了一场革命性的进步,即“以塑代钢”。随着高分子材料科学技术的飞跃进步,塑料管材开发利用的深化,生产工艺的不断改进,塑料管道淋漓尽致地展示其卓越性能。在今天,塑料管材已不再被人们误认为是金属管材的“廉价代用品”。在这场革命中,聚乙烯管道倍受青睐,日益发出夺目的光辉,广泛用于燃气输送、给水、排污、农业灌溉、矿山细颗粒固体输送,以及油田、化工和邮电通讯等领域,特别在燃气输送上得到了普遍的应用。
A revolutionary progress has been made in the field of pipelines, namely “to replace steel with steel.” With the rapid progress of science and technology of polymer materials, the deepening of the development and utilization of plastic pipe, the continuous improvement of production technology, plastic pipe vividly demonstrate its superior performance. Today, plastic pipe is no longer mistaken for metal pipe “cheap substitute ”. Polyethylene pipes are gaining popularity in this revolution, and they are increasingly used for gas transmission, water supply, sewerage, agricultural irrigation, fine-grained solid transportation in mines, and fields such as oil, chemical and postal telecommunications, especially in Gas transmission has been widely used.
