Foreword

This standard was drafted in accordance with the rules given in GB/T 1.1-2009. This standard is a revision of CJ/T 111-2000 "card-type copper pipe joints for aluminum-plastic composite pipes". With CJ/T 111-2000 The main technical content changes are as follows. --- The standard name was changed to "card sleeve type copper pipe joint"; --- Change the "Parts Machining" section to "Geometry" and delete the processing aspects (see 5.2); --- Modify "connection reliability" to "stretch resistance" (see 5.3.1); --- Change the "sealing" to "air tightness" and reduce the test pressure from 1.0MPa to 0.6MPa, in line with other standards (see 5.3.2); --- Change the "static internal pressure strength" to "hydrostatic strength" (see 5.3.3); ---Modify "hydraulic burst" to "hydraulic burst" (see 5.3.4); --- Increase the internal pressure of the thermal cycle test from (690 ± 69) kPa to 1.0 MPa, the alternating temperature of hot and cold from 15 ° C ~ 82 ° C to 20 ° C ~ At 90 ° C, the number of cycles increased from 1000 to 5000 (see 5.3.5); --- Change the thermal cycle test method to the method specified in GB/T 18991-2003 (see 6.8); --- Change Appendix A from a normative appendix to an informative appendix; --- Removed the "reducing tee (middle and one side equal)" pipe joint structure (see A.14). This standard was proposed by the Institute of Standardization of the Ministry of Housing and Urban-Rural Development. This standard is under the jurisdiction of the Building Water Supply and Drainage Standardization Technical Committee of the Ministry of Housing and Urban-Rural Development. This standard was drafted. Zhejiang Zhongyuan Maple Leaf Pipe Co., Ltd., Guangzhou Maple Leaf Pipe Co., Ltd., Guizhou Maple Leaf Pipe Co., Ltd. Zhejiang Jiuhao Technology Development Co., Ltd. The main drafters of this standard. Zhang Wenlong, Zhu Shiming, Yan Chao, Yang Kejie, He Jianxing, Wang Xinlu, and Qi Yongquan. The previous versions of the standards replaced by this standard are. ---CJ/T 111-2000. Card sleeve copper pipe joint
