Large Diameter Aluminum Extruded Pipe | Round Aluminium Tube for Structural and Industrial Use

Product Overview

This large diameter aluminum extruded pipe is a round aluminium tube formed by hot extrusion and used as a structural or fabrication pipe. The round hollow section carries load evenly around the circumference, which makes it suitable for frames, supports, rails and general engineering work where a light pipe is preferred over steel.

Extrusion produces the pipe as one continuous section with a uniform wall, so long lengths keep a consistent shape and the same profile can be cut into the sizes needed for a project.

Material and Extrusion

• Material: aluminium alloy, extruded as a round hollow pipe
• Process: hot extrusion of a round billet through a pipe die
• Section: circular hollow pipe in a large outside diameter range
• Wall: uniform wall around the round section
• Length: extruded in mill lengths and cut as required

Aluminium is lighter than steel for the same volume and forms a natural oxide layer on the surface, so extruded aluminium pipe suits structures that must stay light and resist rust.

Profile and Dimensions

The pipe is supplied as a round section. Outside diameter and wall thickness are chosen together, because a larger diameter gives more bending stiffness while wall thickness controls local strength and weight. A round profile also allows the pipe to be rotated, joined with standard round fittings and welded in any orientation.

• Round outside profile with a hollow centre
• Large diameter sizes for structural and load-bearing use
• Uniform wall for stable bending and welding
• Straight lengths suitable for cutting into frames and rails

Surface and Finishing

Pipe is normally supplied in mill finish with the light extrusion lines typical of the process. It can also be finished by anodizing for a harder coloured surface, or left bare for fabrication where the pipe will be painted or welded after assembly.

Typical Applications

• Structural frames, supports and bracing
• Industrial equipment and machine guarding frames
• Handrails, rails and round pipe assemblies
• Display, exhibition and shop fitting structures
• General fabrication where a light round pipe is needed

Because the pipe is a standard extruded section, it can be combined with plates, brackets and castings by welding or bolting, and cut to the length of each member in an assembly.

Customization and Quality Control

Selection covers outside diameter, wall thickness, cut length, alloy and surface finish. Extruded pipe is checked for straightness, roundness and wall consistency, and cut lengths are checked against the ordered size before packing.
