6. EDITION (November 2005) with Changes 1, 2, 3, approved in March 1983, July 1984-June 1989 (7 to 83 IUS, 11−84, 11−89), Amendment (ICS 6−2004).


A Change N 4, approved and promulgated by the Order of Rosstandart on 02.06.2016 N 506-St c 01.01.2017

N 4 a change made by the manufacturer of the database in the text IUS N 9, 2016


This standard applies to extruded tubes of aluminium and aluminium alloys, designed for the needs of the national economy and exports.

(Changed edition, Rev. N 3).

1. CLASSIFICATION

1.1. The pipes are divided as follows:

form

round and shaped;

wall thickness

round thin-walled with wall thickness up to 5.0 mm, inclusive;

round thick-walled with wall thickness more than 5.0 mm;

as material

without heat treatment (hot-pressed) — marked brand name of the alloy without additional signs;

annealed — M;

hardened and naturally aged — T;

hardened and artificially aged — T1.

Pipe in quenched and naturally aged condition of the aluminum alloy grade 1915 with a wall thickness of not more than 10 mm is permitted to manufacture without heat treatment if they are on the mechanical properties satisfy the requirements for pipe in quenched and naturally aged condition.

(Changed edition, Rev. N 1, 2).

2. ASSORTMENT

2.1. Dimensions round tubes (outer diameter and wall thickness) and maximum deviations and the theoretical weight of 1 m of pipes shall be as specified in table.1.

If there are disagreements chemical composition determined by chemical method.

(Changed edition, Rev. N 3, 4).

5.2. Measurement of pipes the outside diameter and wall thickness is carried out with a micrometer according to GOST 6507 or other tool, to ensure the necessary measurement accuracy.

Check the length of the pipes is carried out measuring tape according to GOST 7502 or metal ruler according to GOST 427.

5.3. The deviation from straightness of tubes check the following way: the pipe is placed on a test plate. Check the pipe to make a metal ruler measuring length of 1 m according to GOST 427, and using the probe on the other 2−034−225* measure the maximum distance between the line and the pipe according to GOST 26877**.

Allowed to use other methods and measuring tools that provide required accuracy.

5.4. Inspection of the outer surface of the pipe is carried out without the use of magnifying devices.

Inspection of the outer surface of the pipe in coils and spools is carried out in the winding process.

Inspection of internal pipe surface hold the lighted screen.

The inspection of the inner surface of tubes in coils and spools is carried out on samples with a length of not less than 100 mm cut from the end of the Bay or the spool.

The depth of defects measured by profilometer according to GOST 19300 or depth gauge indicator according to normative-technical documentation.

5.3, 5.4. (Changed edition, Rev. N 3).

5.4.1. The cleaning of tubes is carried out in the longitudinal direction with an abrasive, scraper or sanding cloth is not larger than the 6-th number of grain according to GOST 5009.

The final cleaning of the pipe to a smooth surface is carried out with sandpaper on paper no larger than 10-th number of grain according to GOST 6456.

5.4.1. (Added, Rev. N 1).

5.5. The tensile test is carried out according to GOST 10006 longitudinal samples with the calculated length

The selection and preparation of samples for tensile tests are produced according to GOST 24047 or GOST 10006.

(Changed edition, Rev. N 1, 2, 3).

5.6. The macro-structure of thick-walled pipes checked for cross microtemplate carved with utrennego end of the pipe, according to the method of the manufacturer.

In the presence of utiny to check the pipes (subject to compliance with the macrostructure of the other requirements) it should be completely removed, and the remaining pipe of the party cut to value the highest prevalence of utiny.

(Changed edition, Rev. N 1, 3, 4).

5.7. The microstructure of the pipe test on the same sample by the method of the manufacturer.

In the presence of burnout re-control of the microstructure is not allowed.

5.8. The presence of nitrate test applying to the surface of the pipe in any place drops of 0.5% solution of diphenylamine in sulfuric acid (the sample 0.5 diphenylamine poured 10 cmof distilled water and 25 cmof sulphuric acid of density 1.84 g/cm).

Upon dissolution of diphenylamine solution volume is adjusted to 100 cmby the addition of sulfuric acid density 1.84 g/cm. Intense blue drops of solution with 10−15 points to the presence in a given location nitrate. After the test drop is removed with filter paper and the tested area is washed thoroughly with water and wipe off.

6. MARKING, PACKAGING, TRANSPORTATION AND STORAGE

6.1. Thin-walled tubes and thick-walled pipes up to 60 mm inclusive tally in bundles according to GOST 9.510, to which is attached a label indicating the grade of aluminum or aluminum alloy, condition of material, batch number and the mark of the technical control Department of the manufacturer.

At the end of each thick-walled tube with a diameter of 60 mm must be embossed or painted: make of aluminium or aluminium alloy as material, the batch number and the stamp of the technical control of the manufacturer.

6.1.1. Pipe manufactured buchtova way, contact no less than three places soft aluminum wire according to GOST 14838. To the Bay or the spool is attached a label indicating the grade of aluminum or aluminum alloy, material, dimensions, batch number and the mark of the technical control Department of the manufacturer.

Metal spools are returnable packaging.

(Added, Rev. N 3).

6.2. Temporary corrosion protection, packaging, transportation and storage — by GOST 9.510. Transport marking of packages — according to GOST 14192 with the additional drawing:

product;

grade alloy;
