Pipe lengths of over 8 m are made by agreement between manufacturer and consumer.

Maximum deviation along the length of the pipe dimensional and multiple lengths shall be +15 mm.

5. Cold-deformed pipes are manufactured:

random lengths — from 1 to 11.5 m;

lengths from 4.5 to 9 m;

Extension table 2

Notes:

1. Pipe sizes, the weight of which is outside the bold lines and the outer diameter of 100−250 mm with a ratio of more than 50 and the pipe ratio of less than 4, are made by agreement between manufacturer and consumer.

2. Weight of 1 m of pipe calculated by formula where a  — outer diameter, mm;  — wall thickness, mm Density of steel is taken equal to 7,850 g/cm.

6. Maximum rejections of sizes of pipes shall not exceed:

a) hot rolled:

the outside diameter

±0.35 mm for disc diameter up to 50 mm incl.,

±0,8% — with a diameter of over 50 mm to 219 mm incl.,

±1,0% — at a diameter of 219 mm,

±0,5% — with a diameter of from 68 to 194 mm incl. ratio equal to 4−10.

wall thickness

±10% for wall thickness up to 15 mm incl.,

±8% for wall thickness more than 15 mm,

±6% for wall thickness from 7 to 45 mm with a ratio equal to 4−10.

In the field to repair defects of hot-rolled pipes, maximum deviations must meet the requirements of GOST 8732, table.2, for pipes of high accuracy of manufacture;

b) cold-drawn:

the outside diameter

±0.10 mm for disc diameter up to 30 mm incl.,

±0.15 mm for disc diameter from 32 to 40 mm incl.,

±0.20 mm — at diameter from 42 to 50 mm incl.,

±0.25 mm — at diameter from 51 to 60 mm incl.,

±0,30 mm for disc diameter from 63 to 70 mm incl.,

±0.35 mm for disc diameter from 73 to 80 mm cyl.,

±0.40 mm for disc diameter from 83 to 90 mm incl.,

±0.45 mm when the diameter of 95 to 108 mm incl.,

Mm ±0.50 mm for disc diameter from 110 to 120 mm incl.,

±0,8% — with a diameter of 130 mm and more;

wall thickness (for pipe diameters 5−108 mm)

Of ±0.05 mm with a wall thickness of from 0.2 to 0.8 mm incl.,

±7,5% for wall thickness of more than 0.8 to 5 mm incl.,

±6,0% for wall thickness greater than 5 mm;

wall thickness (for tubes with a diameter of 110−250 mm)

±10% for wall thickness up to 2,5 mm incl.,

 — with a wall thickness of more than 2.5 to 5 mm incl.,

±7,5% for wall thickness more than 5 mm.

For pipes with a ratio equal to 4−10, in the field to repair defects allowed refinement* wall to minus 8% of nominal value.

When the supply of cold-deformed tubes with the ratio equal to 50 and over in the annealed condition maximum deviations for the outside diameter are determined by agreement between manufacturer and consumer.

4−6. (Changed edition, Rev. N 2).

7. At the customer’s request it is possible to produce pipes of high accuracy with only one parameter.

In this case, the limiting deflection another parameter must meet for hot rolled pipes GOST 8732, and for the rest — GOST 8734.

8. Pipes are produced in outside diameter and wall thickness.

At the request of the consumer pipe is cold after conversion can be made at the inner diameter and wall thickness.

Tolerances for the inner diameter of a pipe with inner diameter more than 10 mm should correspond to the limit deviations for outer diameter. If the internal pipe diameter less than 10 mm, the maximum deviations are established by agreement between manufacturer and consumer.

9. Ovality and raznoshennoy pipes shall not withdraw the pipe dimensions limit deviations for outer diameter and wall thickness.

10. The curvature of the pipe section length of 1 m must not exceed:

1.5 mm for hot-rolled tubes;

2.0 mm for cold-deformed pipes with diameter up to 10 mm and 1.5 mm — for pipes with a diameter of over 10 mm.

For pipes with a ratio of 50 percent or more, produced without heat treatment, the norm of the curvature is not regulated.

At the request of the consumer pipe is manufactured with a reduced curvature of the norms set by agreement between manufacturer and consumer.

(Changed edition, Rev. N 2).
