3 Assortment

3.1 Pipes by the manufacturing method are divided into two types: seamless and electrically welded, straight-seam.

3.2 In accordance with the order of the pipe should be:

— without thread — H;

— smooth with triangular thread and coupling — G;

— with outwardly planted ends with a triangular thread and a clutch — B;

— smooth and with outwardly planted ends and couplings with triangular thread and sealing rings of nonmetallic materials — PG and PV;

— smooth high-hermetic with trapezoidal thread and coupling — T;

— high-tight, non-coupling with outward-directed ends and trapezoidal threads — B.

The pipe assortment is shown in Table 1.

In millimeters

(Changed edition, Rev. N 1).

3.3 Pipes and couplings to them must correspond to the dimensions and weights indicated:

— for pipes without threads — in tables 1−5;

— for smooth pipes with triangular thread and couplings to them — in figure 1 and in table 2;

— for pipes with outwardly threaded ends with triangular thread and couplings to them — in figure 2 and in table 3;

— for smooth high-hermetic pipes with trapezoidal thread and couplings to them — in figure 3 and in table 4;

— for pipes of high-leakage couplings with outwardly planted ends and trapezoidal threads — in figure 4, in table 5 and in section 4 of this standard.

NOTE In determining the mass of pipes and couplings in Tables 2−5, the steel density is assumed to be 7.85 g / cm .

3.4. The edges of the ends of pipes without threads of all strength groups with smooth and outward-planted ends must be blunted.

3.5 At the request of the customer, couplings for pipes with triangular threads with smooth and outward-planted ends can be manufactured with sealing rings of non-metallic materials with technical requirements not lower than those specified in GOST 10007 for pure polytetrafluoroethylene with 25% fiberglass (figure 5).

3.6 Pipes shall be of the two groups of lengths given in Table 6.


Table 6 — Pipe length groups

In meters

For 1% or less of the scope of supply of electric welded pipes, it is allowed to have deviations of no more than 0.25 m in length.

3.7 The maximum deviation in size and weight of pipes and couplings to them should not exceed the values given in Table 7.


Table 7 — Limit deviations of the dimensions and masses of pipes and couplings to them

It is allowed to increase the outer diameter in excess of the plus tolerance up to 1.0 mm behind the transitional landing site for a length of not more than 100 mm for pipes B and not more than 150 mm for pipes B.

The deviations in the wall thickness of the pipe are limited by the tolerances for the outer diameter and mass of the individual pipe.

(Changed edition, Rev. N 1).

3.8 On the end sections equal to one third of the length of the pipes G, H and T, and at a distance of 125 to 150 mm beyond the transitional landing site of the pipes B and B, the curvature of more than 1.0 mm per 1 m of length shall be prohibited.

The curvature, measured at the middle of a pipe 114 mm in diameter, should not exceed ½ of its length; for pipes of other diameters, the curvature is regulated by the passage of a cylindrical mandrel inside the pipe.

3.9 When ordering pipes, the customer must specify the following:

— pipe designation according to 3.2 of this standard;

— conventional diameter;

— Wall thickness;

strength group;

— group (range) of length;

— weight (number) of pipes;

— the designation of this standard.

When ordering couplings, the consumer must specify:

— designation of the coupling for the pipe: sleeve for pipes with smooth G or with outwardly planted ends At the ends with triangular thread; couplings with a triangular thread and a sealing ring of non-metallic materials P or without it; coupling for pipes smooth high-tight with trapezoidal thread T;

— the conditional diameter of the pipe corresponding to this clutch;

strength group;

— the presence of grooves under the sealing rings of non-metallic materials and the conditions for the supply of rings (in couplings and separately from them);

— quantity;

— the designation of this standard.

Examples of symbols for pipes and couplings to them are given in Appendix A.

3.10 When ordering, the customer may specify additional requirements:

— control of mechanical properties (for example, by testing the material for impact bending at low temperatures);

— coating material (other than phosphating) of the coupling thread;

— application of protective coatings on the inner surface of pipes;

— the use of special lubricants or seals when screwing the threaded connections in the manufacturer’s conditions;

— the value of the test hydraulic pressures;

— by marking and packing;

— according to the conditions of the pipe inspection from the manufacturer (or supplier), as well as other possible additional requirements or agreements.
