CJ/T 159-2015Polyolefin/aluminum/polyolefin composite pressure pipe (butt-welded by aluminum pipe) (English PDF)

Foreword

This standard was drafted in accordance with the rules given in GB/T 1.1-2009.

This standard applies to the modification of PP-RCT material requirements using ISO 15874-1 "plumbing and plumbing systems - polypropylene - Part 1. General" in the PP-RCT material requirements.

This standard replaces CJ/T 159-2006 "aluminum-plastic composite pressure pipe (butt welding)." This standard compared with CJ/T 159-2006 main technology the changes are as follows.

--- Revised the production of pipe, pipe fittings used in the requirements of heat-resistant polyethylene material;

--- Increased inner and outer plastic random copolymer of polypropylene six-type aluminum-plastic composite pipe;

--- Increasing the production of pipe, pipe fittings used random copolymerization polypropylene material requirements;

--- Increasing the minimum average tube ring high temperature peel strength requirements and test methods;

--- Remove the original standard Appendix A, Appendix B, Appendix C, Appendix D, Appendix F.

This standard proposed by the Ministry of Housing and Urban Standard and Design Institute.

This standard by the Ministry of Housing and Urban Water Supply and Drainage Standardization Technical Committee building centralized.

This standard was drafted. Wuhan Jinniu Economic Development Co., Ltd., the State Chemical Building Materials Testing Center, China Academy of Architectural Design Limited the company.
