Foreword
This standard was drafted in accordance with the rules given in GB/T 1.1-2009.
This standard refers to the German gas and water professional association standard DVGW W534.2015 "fittings and fittings in drinking water installations",
DVGWVP614.2005 "Test specification of metal pipe clamped connections for gas transmission", and compiled in conjunction with China's specific conditions
This standard.
This standard is proposed by the Institute of Standardization of Housing and Urban-Rural Development Standards.
This standard is under the jurisdiction of the Ministry of Housing and Urban-Rural Construction Water Supply and Drainage Standardization Technical Committee.

Gear ring compression thin-walled stainless steel pipe fittings
1 Scope
This standard specifies the classification and marking of toothed ring compression thin-walled stainless steel pipe fittings, structure type and size, requirements, test methods, and inspection rules.
Then, signs, packaging, transportation and storage.
This standard applies to the transmission of liquid medium when the nominal pressure is not greater than 2.5MPa, the temperature is not greater than 110 °C, when conveying gas medium nominal
The pressure is not more than 1.6MPa and the nominal size is not more than DN100. It is used to transport domestic water (cold water, hot water), drinking water, medical gas, and
Heat, compressed air, inert gas, fuel gas, fuel oil, etc. are used in the design, manufacture, and acceptance of toothed ring pressurised thin-walled stainless steel piping.
