Foreword

This standard is drafted in accordance with the rules given in GB/T 1.1-2009. This standard uses the re-drafting method to modify ISO 16132..2004 "ductile iron pipe and pipe cement mortar liner seal coating". This standard has more structural changes compared to ISO 16132..2004, which is listed in Appendix A and ISO 16132..2004 Of the chapter number of the control list. There are technical differences between this standard and ISO 16132..2004, and the terms involved in these differences have been passed through the margin (│), and a list of the corresponding technical differences and their causes is given in Appendix B. This standard has also made the following editorial changes. --- "this standard" instead of "this international standard"; --- use the decimal point symbol "." Instead of the symbol ","; - delete the catalog of international standards, preface and introduction. This standard is proposed by China Iron and Steel Industry Association. This standard is under the jurisdiction of the National Steel Standardization Technical Committee (SAC/TC183). The drafting of this standard unit. the new Cast Iron Pipe Co., Ltd., Gaoping City, Kwong's Casting Co., Ltd., Metallurgical Industry Information Standards Institute. The main drafters of this standard. Li Jun, Wang Xuezhu, Li Ning, Ye Weide, Ding Baohua, Hou Jie, Zhu Yongchang. Ductile iron pipes and fittings Cement mortar lining seal coating

1 Scope

This standard gives the requirements for coating a coating on ductile iron pipes and pipe cement mortar lining surfaces in a factory. Cement mortar Lining is also lining in the factory. This standard also gives a short-term sealing performance, long-term sealing performance, hydraulic cycle test type test requirements and daily tests such as appearance, Thickness and adhesion requirements and test methods. This standard applies to the supply of cement mortar lining seal coating ductile iron pipe and pipe fittings. Note. The role of the seal coating is to reduce the cement mortar lining and water supply pipe in the water contact to limit the infiltration of inorganic materials into the water, while reducing the water resistance, Improve water delivery capacity.
