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.
This standard is proposed by China Iron and Steel Industry Association.
