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 152-2010 "thin-walled stainless steel compression and grooved pipe fittings," compared with CJ/T 152-2010, the main technical changes are as follows.

--- Modify the steel uniform number code, grade and increase the applicable conditions;

--- Increased the nominal size of pressure pipe fittings series;

--- Increased the structure and size of the compression fittings;

--- Increased gas application of the technical requirements and test methods;

--- Increased the color of drinking water and gas pipelines logo requirements;

--- Modify the technical requirements, test methods and other technical content.

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.
