Scope

Main technical content: In 1992, the China Engineering Construction Standardization Association issued the "Design and Construction Acceptance Procedures for Polyvinyl Chloride Pipelines for Building Water Supply" CECS 41:92. Over the past 10 years, China has made great progress in increasing the specifications of this type of pipe and fittings, improving their quality, and perfecting technical supporting measures. In addition, we have accumulated a lot of new experience in design and construction installation. Therefore, the original regulations can no longer meet the current needs for further promotion and application of this type of pipe, and it needs to be revised and improved. The content of this regulation includes general principles, terminology, materials, pipe connection, design, construction, and acceptance, etc. This revision is based on the summary of engineering practice experience over the past 10 years, referring to foreign technical developments and the revision of relevant Chinese standards, and making a comprehensive revision of the original regulations. New content has been added to the technical performance requirements of pipes, fittings, and joint materials, the selection of pipe pressure grades, hydraulic calculation of pipes, pipe connection techniques and laying methods, and pipe expansion compensation measures, as well as the reasonable setting of brackets.
