Benefits Of Custom Aluminum Pipe

The following are the benefits of custom Aluminium pipe:


Custom Aluminium pipe is made from the line; hence is relatively stable and able to stay for long without falling.

Good Heat Conductivity

Custom Aluminium pipe is primarily used in appliances and electrical engines that require temperature control because it allows for good heat conductivity.

Aluminium conducts heat exceptionally well, making Aluminium tubing a great candidate.


Custom Aluminium pipes are suitable for high mobility applications because of their unmatched strength-to-weight ratio.

Good Hygiene

Custom Aluminium pipe is made of unique polyethene material that is non-toxic and clean, inside and outside the line.

Malleability And Strength

Custom Aluminium pipe is solid and elastic hence suitable for its transportation applications.

Corrosion Resistance

The custom Aluminium pipe does not rust, hence is corrosion resistance.

Therefore, its resistance to corrosion helps reduce the maintenance cost of treating the rust forming on the surface after installation.

Choosing Material Grade For Custom Aluminum Pipe

The following are some of the material grades for custom Aluminium pipe:


This alloy for custom Aluminium pipes is majorly applied in aircraft uses because of its fatigue resistance and high strength.

It has average machinability and can be welded.

Custom Aluminum Pipe Temper Options

The temper option process is where physical properties achievable within a custom aluminium pipe are varied.

When choosing a custom aluminium pipe to suit the applications, it is designed for them, and it is essential to find out which range of temper options suits the needs.

Temper options also change how the custom aluminium pipe might react to fabrication processes such as welding, forming, or punching and alter its characteristics.

Temper options are important because the user and the producer know that the custom aluminium pipe has been thermally or mechanically treated to attain the desired properties.

custom aluminum pipe temper

custom aluminum pipe temper

The following are the temper options available for custom aluminium pipe:

F, As Fabricated

This process involves using semi-finished F- temper products to attain other finished tempers through finishing, shaping, and thermal processes.

  • H, strain-hardened

This type of temper option is done to the non-heat-treatable custom aluminium pipe, which by hardening at room temperature, its strength had been increased.

The main H, strain-hardened for custom aluminium pipe, is H14.

O, Annealed

It is used to attain the lowest-strength state for the custom aluminium pipe.

Annealing treatment’s importance is maximizing flexibility and toughness and increasing workability.

T, Thermally Treated.

This process is done on a custom aluminium pipe that is heat-treatable.

The process follows ageing and quenching after the custom aluminium pipe has been given a solution heat treatment.

They include; T3, T4, and T6.

W, Solution Heat-treated

It is rarely a finished temper applied on the custom aluminium pipe that ages voluntarily and naturally after treating the solution.

Customs Aluminum Pipe Fabrication

The following are how the custom aluminium pipe is fabricated:

Cutting Aluminum Pipe

Cutting can be used as the first step in an extensive fabrication process of custom aluminium pipes.

Cutting involves a custom aluminium pipe being cut into smaller pieces or the material being split.

Cutting is done in different ways, which include:

  • Plasma arc cutting
  • Laser cutting
  • Waterjet cutting
  • Power scissors



Welding Aluminum Pipe

Welding is used to fabricating sheet metal brass into the desired shape and thickness.

The following are the methods used in the custom aluminium pipe welding process:

  • TIG welding

TIG is suitable for sheet metal thicknesses ranging from 8-10mm.

TIG uses an infusible tungsten-based electrode and electric arc to generate welds.

  • Laser welding

Laser welding is a fabrication process that melts the metal using a solid-state, high-powered laser resonator.

This process provides for consistency of production and high-quality welds.

  • MIG welding

This welding involves a wire electrode repeatedly fed through the welding gun and then into the weld pool.

Shielding gas is fed through the gun to protect the pool from contamination.

Bending Aluminum Pipe

Bending is a process that involves pipe bending to fit in with the required specifications.

The following are the factors to consider before the custom aluminium pipe bending process:

  • Mechanical strength
  • Surface areas that are analytic for appearance.
  • Length, the expected deviations, and tolerances on the inside and outside dimensions.

The following are the methods of custom aluminium pipe bending:

  • Hydraulic rotary draw bending

This method involves an extruded custom aluminium pipe placed onto a bender and held in place with a sliding pressure die or stationary and clamping block.

Hydraulics powers the round bending die to rotate up to 90 degrees as the extrusion rotates as it bends.

This method allows for only one radius at a time of extrusion to bend.

This method is used when round pipes are formed for various applications and is suitable for custom aluminium pipes with large diameters.

  • Push or ram bending

Using ram, an extruded custom aluminium pipe piece is forced on a bending die.

The extrusion is pushed onto the pressure dies by a die forcing it to bend.

This method allows close accessibility to various plane bends if bend angles are programmable, though one radius is allowed to turn at a time.

The advantage of ram bending is that it gives good bend precision at a lower cost and relatively inexpensive tooling.

  • Electric rotary draw bending

This type of bending is the same as hydraulic rotary draw bending, just that its setup is faster.

Rotations and angles can be automated in machines. Thus bends can be easily repeated and are more accurate.

This method can also mechanize the extruded custom aluminium pipe rotations for uneven plane bends.

Sizing Custom Aluminum Pipe

Sizing a custom aluminium pipe generally involves measuring the size of the line.

Firstly, when sizing the custom aluminium pipe is to know whether the outside or inside diameter is being measured. A tape measure or ruler is used to measure.

Steps in measuring the diameter:

  1. The suitable diameter being measured
  2. Converting to Nominal Pipe Size
Custom Aluminum Pipe Surface Finish

Advantages of surface finish treatment for custom aluminium pipe:

  • Protects the surface from corrosion
  • Provides for durability
  • It gives the character a good appearance
  • Surface finish alters the surface hardness and resistance to abrasion.

The following are the types of custom aluminium pipe surface finish available:

Powder Coating

Powder coating is where a dry powder is electrostatically applied to the custom aluminium pipe to form a layer.

Liquid Paint

This type of surface finish treatment gives a uniform thickness, varying in colour.

With liquid paint, the VOCs are driven off during the baking process, unlike powder coating.


Anodizing is an electrochemical process that makes the custom aluminium pipe durable, in which the natural oxide film is given further protection.

Anodizing increases the thickness of a custom aluminium pipe layer through the passive electrolytic process.

The anodized custom aluminium pipe can gain vibrant colours.

Custom Aluminum Pipe Manufacturing Process

Custom aluminium pipes are manufactured differently; seamless, welding and extrusion.

The following are the processes of manufacturing custom aluminium pipe:

Custom Aluminium Pipe Seamless Manufacturing Process

This process manufactures lines in the accuracy of schedule and size.

Here, a rod is heated to a high temperature then a hole is formed through the cylinder after a probe has been inserted.

After that, the cylinder is conveyed to rollers that size the cylinder to a specific wall thickness and diameter.

Custom Aluminium Pipe Extrusion Process

In this process, a heated billet is inserted inside the die.

Against the piercing mandrel, a hydraulic ram thrusts the billet.

From the cylindrical cavity, material flows between the mandrel and die. This movement generates the pipes from the billet.

Custom Aluminium Pipe Welding Process

The welding process involves manufacturing pipes from continuous coil o strips or plates.

With the help of a roller given constant process or a plate bending machine, the first coil or plate is rolled in the circular section.

Once the circular section is moved from the plate, the pipe can be rolled either with or without the material filler.

This process can produce large-size custom aluminium pipes with no upper restrictions.

Lines manufactured through this process are cheap and weak due to the weld.

The following are the welding methods that can be sued to weld custom aluminium pipes:

  • Submerged Arc Welding (SAW)
  • Electric Resistance Welding (ERW)
  • Electric Fusion Welding (EFW)
  • High-frequency Welding (HFW)
Customs Aluminum Pipe Fittings

Different custom aluminium pipe fittings are available for other applications.

They are used to join many pipes of different sizes to secure leak-free connections and measure the flow.

The following are the types of custom aluminium pipe fittings:


Elbow pipe fittings can be fixed by socket welding or butt and are used to alter the direction of flow between two pipes.


Reducer pipe fitting reduces the pipe size to reduce the flow size from larger to more minor.

There are two types of reducers; eccentric and concentric.


The coupling is the suitable pipe fitting for custom aluminium pipes of the same diameters. They are used for lines where leakage occurs or is broken.

Types of coupling are compression and slip yoke.


Cap is a pipe fitting containing female threads and functions like the plug pipe fitting.

Tee-type pipe fitting

It is a pipe fitting in a T-shape and has outlets arranged at 90 degrees; one and two outlets to the main inlet.
