Aluminum Round Pipe

Aluminium pipe is used in pressure or structural application. These Aluminium Pipe are light weight, excellent corrosion resistance, and the ability to transmit heat rapidly are only a few of the benefits of aluminum pipes.
Product introduction
Aluminium Pipe can be produced in two types drawn and extruded aluminum pipe. Extruded aluminum pipe is stocked in both seamless and structural (port-hole die). Aluminium pipe is used in pressure or structural application. These Aluminium Pipe are light weight, excellent corrosion resistance, and the ability to transmit heat rapidly are only a few of the benefits of aluminum pipes.

There are 2 types of Aluminium Pipe:

1) Aluminium Extruded Pipe: Aluminium Extruded Pipe, formed by hot extruding through a die, is available as a seamless or structural grade product.
2) Aluminium Drawn Pipe: Aluminium Drawn Pipe is a seamless extruded Pipe is brought to final size by drawing through a die.

Heat Treating T Temper Codes for Aluminium Pipe
T1 – Cooled from an elevated temperature shaping process and naturally aged to a substantially stable condition.
T2 – Cooled from an elevated temperature shaping process, cold worked, and naturally aged to a substantially stable condition.
T3 – Solution heat treated, cold worked, and naturally aged to a substantially stable condition.
T4 – Solution heat treated, and naturally aged to a substantially stable condition.
T5 – Cooled from an elevated temperature shaping process then artificially aged.
T6 – Solution heat treated then artificially aged.
T7 – Solution heat treated then overaged/stabilized.
T8 – Solution heat treated, cold worked, then artificially aged.
T9 – Solution heat treated, artificially aged, then cold worked.
T10 – Cooled from an elevated temperature shaping process, cold worked, then artificially aged.
Additional digits may be used after the first T temper digit to indicate subsequent stress relieving by processes such as stretching, compressing, or a combination.

H Temper Strain Hardening Codes for Aluminium Pipe
H1 – Strain hardened only
H2 – Strain hardened and partially annealed
H3 – Strain hardened and stabilized
H4 – Strain hardened and lacquered or painted. This assumes that thermal affects from the coating process affect the strain hardening; seldom encountered.
