- 摘要:
- 根据笔者接触和参与的大口径管道玻璃钢外护层保温管道工程的实践,发现玻璃钢有许多优点,用于大口径管道保温外护层要优于高密度聚乙烯。文章首先介绍了关于玻璃钢的有关规定,进而分析了对玻璃钢产生偏见的主要原因及大口径聚乙烯套管生产中存在的问题,阐述了玻璃钢外护层的优缺点,例举了玻璃钢用于大口径管道保温外护层的工程实例。
The engineering practices of large diameter insulation pipeline with outer glass fiber reinforced plastic protection layer, in which the authors participate, prove that the performance of glass fiber protection layer is better than high density PE protection layer. This paper outlines the relevant provisions and rules of glass fiber reinforced plastic, analyzes the main reasons causing prejudice against glass fiber reinforced plastic and the existing problems in PE casing production, expatiates on advantages and disadvantages of glass fiberreinforced plastic, and illustrates some practical projects that apply glass fiber reinforced plastic for protection layer of large diameter insulation pipeline.2007,4(4): 52-54 收稿日期：2007-6-18分类号：TE973.3作者简介：邵秋(1977-),男,河北定州人,1999年毕业于武汉水利电力大学热能动力专业,曾从事热能工程设计及管道防腐保温技术开发工作,现任河北华孚管道防腐保温有限公司经理兼总工程师。参考文献：
