Information about the standard

1 DEVELOPED by LLC "NTC Systems of pipelines made of polymeric materials"

2 INTRODUCED by the Technical Committee for Standardization TC 465 "Construction"

3 ADOPTED by the Interstate Council for Standardization, Metrology and Certification

4 Order of the Federal Agency for Technical Regulation and Metrology dated November 18, 2014 No. No 1639-st interstate standard GOST 22689-2014 was put into effect as a national standard of the Russian Federation on July 1, 2015.

5 This standard complies with the international standard ISO 8770:2003 Plastics piping systems for soil and waste discharge (low and high temperature) inside buildings - Polyethylene (PE) European Standard EN 1519-1:1999 Plastics piping systems for soil and waste discharge (low and high temperature) within the building structure * Polyethylene (PE) - Part 1: Specifications for pipes, fittings and the system plastics for wastewater (low and high temperature) discharges inside buildings - Polyethylene (PE) - Part 1: Specification for pipes, fittings and system].

Degree of conformity - non-equivalent (NEQ)

** On the territory of the Russian Federation, GOST R ISO 3126-2007 applies.

4.1.2 The wall thickness shall be in accordance with Table 2.

GOST 22689-2014

Table 2 In millimeters

Allowed wall thickness at any point is not more than 1.25e tp, provided that the average wall thickness e t is not more than e t max.

4.1.3 The pipe length / (effective) measured in accordance with Figure 1 shall be specified by the manufacturer. The maximum length deviation is ± 10 mm.

a) Pipe with a socket for an o-ring

b) Pipe without a socket with a chamfer and without a chamfer

Figure 1 - Effective pipe length

4.1.4 When manufacturing pipes with a chamfer, the chamfer angle should be from 15° to 45° to the pipe axis. The remaining wall thickness at the end of the pipe must be at least 1/3e mln .

4.2 Dimensions of fittings

4.2.1 The average outer diameter d at of the pipe end shall be in accordance with Table 1.

4.2.2 The minimum wall thickness o rtn of the body or pipe end shall be in accordance with Table 2. A 5% reduction in wall thickness is allowed. in this case, the arithmetic mean value of the thickness of two opposite walls must be at least e mn .

For transition fittings designed to connect pipelines of two different nominal sizes, the wall thickness of each socket (pipe end) must meet the requirements for the corresponding nominal size. In this case, the wall design provides for a smooth change in thickness from one value to another.

The wall thickness of prefabricated fittings (with the exception of the thickness of pipe ends and sockets) can be changed locally during manufacture, provided that the minimum wall thickness corresponds to the minimum value of e 3 . given in table 5.

4.3 Dimensions of sockets and pipe ends

4.3.1 The dimensions of the sockets and pipe ends for the sealing ring (Figure 2 a) must comply with Table 3.

Various designs of the groove for the sealing ring are allowed (Figure 2 b), provided that the characteristics of the connection meet the requirements specified in Table 8.

Flare dimensions, including the maximum average internal diameter of the dvr ggll. and grooves for the sealing ring must be installed by the manufacturer in the design and technical documentation for the product.

If the O-ring creates more than one sealing point (figure 2c), then the minimum value of A and the maximum value of C are measured from the effective sealing point, as specified by the manufacturer.

GOST 22689-2014

d t - inner diameter of the socket; A is the minimum contact length; B - entry length. C - depth of the point of effective compaction; - length of the pipe end; e 2 - socket wall thickness; vz - wall thickness in the area of ​​the groove for the sealing ring

4.3.2 The dimensions of the socket for welding with embedded electric heaters shall comply with Table 4. The average internal diameter of the socket d^ and its maximum deviation shall be indicated in the manufacturer's documentation.

The wall thickness E of the socket with embedded electric heaters must be at least the wall thickness e mn of the corresponding pipe specified in Table 2.

dum is the average inner diameter of the socket, measured at a distance U + 0.5La from the end of the socket; 1_2 - depth of entry of the pipe end; C is the length of the heating zone (fusion);

C - unheated length at the entrance to the socket L 4 2: 5 mm

Table 5_in millimeters

In flare designs where the o-ring is held in place by a bonnet (Figure 4), the wall thickness in this area shall be calculated by adding the flare wall thickness to the bonnet wall thickness in the relevant cross section.

4.3.4 The average outer diameter and wall thickness of the pipe ends of butt welding fittings shall be in accordance with Table 1 and Table 2.

4.4 Types of fittings

This International Standard is applicable to the following main types of fittings:

a) bends (Figure 5) in the following options:

1) pipe end-bell or socket-bell,

2) curved elbow with radius R,

3) welded outlet from pipe segments.

The nominal angle a for the bends is selected from the following values: 15 e. 22.5 e, 30 e. 45 e. 67.5 e. 80 e and from 87.5 ° to 90 e;

b) tees and transitional tees (Figure 6) in the following versions:

1) pipe end-bell-bell or bell-bell-bell,

2) curved tee with radius R,

3) welded tee from pipe segments.

The nominal angle a for tees is selected from the following values: 45°. 67.5 e and from 87.5 e to 90 e:

c) crosses (Figure 7 a) and two-plane crosses (Figure 7 b).

The nominal angle a for crosspieces is selected from the following values: 45 e, 67.5 e and from 87.5 e to 90 e:

d) adapter pipes (Figure 8);

e) double-socket couplings (Figure 9 a) and sliding couplings (Figure 9 b).

f) revisions (Figure 10);

g) branch pipe for butt welding (Figure 11); i) plug (Figure 12).

Other types and designs of fittings are allowed.

The installation length g of fittings must be specified by the manufacturer. The installation length z of fittings is not used for quality control.

The design and nomenclature of fittings must be established in the design and technical documentation of the manufacturer.
