Note — When using this standard appropriate to test the effect of reference standards in the information system of General use — on the official website of the Federal Agency for technical regulation and Metrology on the Internet or in the annual information index «National standards» published as on January 1 of the current year, and the editions of the monthly information index «National standards» for the current year. If the reference standard is replaced (changed), when using this standard should be guided by replacing (amended) standard. If the reference standard is cancelled without replacement, then the situation in which the given link applies to the extent that does not affect this link.

3 Terms and definitions

This standard applies the following terms with respective definitions:

3.1 fitting: a Device in the pipeline system, designed to connect pipes together or with another component of the system.

3.2 nominal diameter: the nominal diameter of the end fitting, expressed as a nominal outer diameter of the joining pipe.

4 Assortment

4.1 Standardized sizes — nominal diameter limit deviation for diameter of the connecting parts and the diametrical clearance of the solder connection must match the values specified in table 1.


Table 1

In millimeters

Maximum deviation of the diameter of the covered and covering the ends out with calibers, the dimensions of which are given in tables A. 1 and A. 2 (Appendix A).

Maximum deviations in diameter given in table 1, and the maximum deviations of the calibers listed in tables A. 1 and A. 2 to ensure a uniform distribution of the low-temperature (soft) and high temperature (hard) solders in a capillary gap and unimpeded mechanical joining of fitting and tube.

4.2 the Names and designation codes of the fittings is given in Annex B. the Installation dimensions of fittings is determined by agreement between manufacturer and consumer.

4.3 Fittings fittings are divided into a covering pipe and fittings covered by the tube. Connection for capillary soldering is shown in figure 1.

Figure 1 — Connection for capillary soldering

1 — tube; 2 — fitting;  — diameter of connected pipes; the length of the inner area solder fitting covering tube in the connection;  — the length of the external section solder fitting covered by the pipe in the connection.

Figure 1 — Connection for capillary soldering

4.4 length of the area under low-temperature (soft) and high temperature (solid) solder to fittings and tolerances for length must match the values specified in table 2.


Table 2

In millimeters

4.5 For cropped fittings use only a high-temperature (hard) solder. The length of the solder and limit deviations of length should correspond to the values indicated in table 3.


Table 3

In millimeters

4.6 Minimum cross section in any part of the fitting should not be less than the theoretically calculated cross section to the minimum diameters specified in table 4.


Table 4

In millimeters

For fittings with different diameters the minimum diameter is taken for each.

4.7 To meet the requirements across the joint during brazing in the fittings shall be provided for the projections, ensuring reliable limitation in the application of connections to the maximum allowable Diametric clearance.

4.8 Minimum wall thickness of the fitting measured at any point shall not be less than the values shown in table 5.


Table 5

In millimeters

The legend of fittings include:

— name, such as tee, coupling, etc.;

— nominal diameter depending on the diameters of connected pipes; fittings designed to connect pipes of the same diameter should be in the designation of this diameter; fittings designed to connect pipes of different diameters are indicated by showing all the outer diameters of the respective pipes;

— brand copper or alloy;

two alphanumeric sign defining a specific manufacturer, that indicate, if necessary, when ordering. In the absence of alphanumeric characters is — XX;

— the basic code designation of the fitting;

— special conditions: shorter fittings.

— the designation of this standard.
