标准范围

本文件规定了ISO中定义的压力和非压力管道用球墨铸铁管和配件用水泥砂浆的性质、应用方法、表面状况、性能要求和内衬的最小厚度？2531，耶稣？7186和ISO？16631.它涵盖了水泥砂浆衬里，与无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特性和/或防止腐蚀损坏，并包括对部分填充运行的重力下水道衬里的特殊要求。它还涵盖用于输送腐蚀性特别强的流体的衬里，其中以下解决方案可以单独使用或组合使用:A）？衬里厚度的增加；b）？水泥类型的变化；c）？衬里上的涂层。

This document specifies the nature, the method of application, the surface condition, performance requirements 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, ISO 7186 and ISO 16631.

It 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.

It also covers linings used for the conveyance of particularly aggressive fluids, where the following solutions can 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.
