标准摘要
[中文适用范围]： 本文件详细说明了聚乙烯薄膜（通常称为聚乙烯套管）的特性，用作球墨铸铁管道的额外防腐蚀保护，特别是在腐蚀性土壤条件下铺设时。 这种薄膜的效率已被经验证明，它采用片材或管材的形式，在管道铺设之前现场安装在管道和配件周围。 [外文原描述]： This document specifies the characteristics of polyethylene film, commonly called polyethylene sleeving, used as additional protection against corrosion for ductile iron pipelines, particularly when laid in aggressive soil conditions. This film, the efficiency of which has been proved by experience, takes the form of a sheet or tube fitted around the pipes and fittings, on-site, immediately before pipe-laying.
英文名称Ductile iron pipelines — Polyethylene sleeving for site application
