CJ/T 199-2018Supply-exhaust pipe for combustion appliance (English PDF)

Foreword

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

This standard replaces CJ/T 199-2004 "Stainless steel for exhaust pipes for combustion appliances". Major technical changes compared to CJ/T 199-2004 the following is as follows.

--- Added terms and definitions (see Chapter 3);

--- Increased the corresponding requirements for aluminum exhaust pipes and non-metal feed pipes (see Chapters 5 and 6);

--- Increased tolerance for the size of the exhaust pipe (see 5.2.2);

--- Increased inter-tube connectivity (see 6.4);

--- Increased resistance to salt spray corrosion (see 6.11);

--- Increased the fit of the elastic seal to the annular groove (see 6.12);

--- Increased material properties of the exhaust pipe elastic seal (see 6.13);

--- Modified tensile strength (see 6.3, 2004 version 4.4);

--- Modified the air tightness requirements (see 6.5, 2004 version 4.4);

--- Modified the classification and model (see Chapter 4, Chapter 3 of the 2004 edition);

--- The contents of the inspection rules are moved into the text (see Chapter 8, Appendix A of the 2004 edition);

--- Removed the clearance for the insertion of the exhaust pipe to the joint (2004 version 4.2.3).

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 Gas Standardization Technical Committee of the Ministry of Housing and Urban-Rural Development.
