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.

3.6.1. For pipes manufactured buchtova method allowed local ovality:

when a diameter of 20 mm is not more than 1 mm;

with a diameter exceeding 20 mm — not more than 2 mm.
