- 摘要:
- 三层PE涂层已在国内的一些管道工程中被采用，对这种防腐涂层应采用的补口材料，有关规范未予明确规定，通过对二层和三层热收缩套补口材料的性能分析对比，提出应选用与管体涂层一致的补口材料。
PE coating ls widely used in domestic pipeline engineering. However there is no specification forjoint coating material. Therefore this paper proposes some joint coating material which match with PEcoating through performance comparison with two-layer and three-layer-hot shrinkage sleeve.1998,3(3): 36-38,3,4 收稿日期：1997-12-11
