Foreword

This standard is drafted in accordance with the rules given in GB/T 1.1-2009. This standard replaces GB/T 12772-2008 "flexible interface cast iron pipe for drainage, pipe fittings and accessories". And GB/T 12772-2008 phase The main technical changes are as follows. - an introduction to the introduction and the right to use the patent; The scope of application indicates the discharge of waste from the building, the flow of gravity as a gravity, and the increase in the discharge of industrial waste water (see Chapter 1); --- to increase the same layer of drainage and special single pipe drainage pipe and swirl pipe fittings related terms and technical requirements; - Increased interface pressure resistance and pipeline seismic performance and test methods (6.3.2, 7.3.2 and appendix E); - Added part of the terminology and classification of fittings (see Chapter 3, Chapter 4); --- to change the size of some pipe fittings, improve the unity of the B-tube size, weight; --- In the cast iron quality requirements for the production of W1-type straight pipe and for the rain pipe A-type B-type straight pipe and pipe cast Grade requirements (see 6.1 and.2008 6.1); - the provision for type inspection (see 8.1); --- Increased water pressure test index, test water pressure increased from 0.3MPa to 0.35MPa (see 7.3.1,.2008 edition 7.1.3.1); --- delete the Appendix A; the A type, W type, W1 type, the same layer of drainage, B-type pipe fittings included in Appendix A; - Replace the W-reinforced stainless steel clamp with a W-type stainless steel clamp clamp and modify the dimensional tolerances (see Appendix C and 2008 edition of Appendix D); - Added normative appendix Appendix E "Interface pressure resistance and pipe seismic performance and test methods"; --- Added information Appendix Appendix F "Buried media and protective methods". This standard uses the re-drafting method with reference to ISO 6594..2006 "Cast iron drainage pipes and fittings series" ISO 6594..2006 consistency is non-equivalent.
