标准范围

ISO 4179:2005规定了ISO 2531和ISO 7186中定义的压力和非压力管道用球墨铸铁管和管件的水泥砂浆内衬的性质、使用方法、表面条件和最小厚度。ISO 4179:2005涵盖了水泥砂浆衬里,与未衬里的管道和配件相比,水泥砂浆衬里用于改善管道和配件的水力性能和/或防止腐蚀损坏,并包括对部分填充的重力下水道衬里的特殊要求。ISO 4179:2005还包括用于输送特别腐蚀性液体的衬里,其中可单独或组合使用以下溶液:a)增加衬里厚度;b) 水泥类型的改变;c) 衬里上的涂层。

ISO 4179:2005 specifies the nature, the method of application, the surface condition and the minimum thickness of internal linings of cement mortar for ductile iron pipes and fittings for pressure and non-pressure pipelines as defined in ISO 2531 and ISO 7186.ISO 4179:2005 covers cement mortar linings which are used to improve the hydraulic properties of pipes and fittings compared to un-lined pipes and fittings and/or to prevent corrosion damage and includes special requirements for linings of gravity sewers operating partially filled.ISO 4179:2005 also covers linings used for the conveyance of particularly aggressive fluids, where the following solutions may be used either separately or in combination: a) an increase in the thickness of the lining; b) a change of the type of cement; c) a coating over the lining.
