Product Description

Aluminum Tubing & Piping

What is Aluminum Tubing & Piping?

Aluminum piping and tubing is silvery-white, soft, and ductile. The metal belongs to the boron group. Aluminum is the third most abundant element present on earth. Aluminum has low density. When exposed to corroding environments, aluminum forms a passivating coating on its surface, which helps it avoid further corrosion on its internal structure. Aluminum is mostly made into an alloy by elements like copper, manganese, zinc, magnesium, and silicon.

These pipes and tubing only have 30% of coppers' density, yet have good electrical and thermal conductivity. Aluminum can be categorized as a superconductor, since it is capable of conducting at cold temperatures.

Piping is a circular tube for the flow of gasses and fluids, characterized by a small pipe size offering a vague representation of the piping conveyance capacity. Tubing is a circular, oval, rectangular, or square hollow segment characterized by outer diameter and wall thickness, denoted in millimeters or inches.

The choices may be overwhelming when choosing a tube type; both aluminum and stainless steel are available in a number of alloys and tempers, all with their own mechanical and physical properties.

Strength of Aluminum Tubing & Piping vs. Steel Tubing & Piping

The strength of every material may be defined by a physical factor called Young's modulus of elasticity, determined in force per unit area. This factor can be utilized to evaluate the strength of aluminum and steel tubing.

Young's Modulus - At 70 °F, Young's modulus of elasticity for aluminum is 10 million psi. For steel, irrespective of the type, it's about 30 million psi. This effectively implies that steel tubing is 3 times stronger than aluminum tubing for the same dimensions.

Material Weight - Size for size, steel is about three times heavier than aluminum. The walls of aluminum tubing are required to be three times thicker than the walls of steel tubing so the weight advantage is insubstantial.

Diameter - The strength of aluminum or steel tubing also depends on the tubing's diameter. The nominal diameter of the tube, the more intrinsic the strength and vice versa.

Manufacturing of Aluminum Tubing & PipingAluminum Extrusion

Aluminum extrusion is a procedure where the aluminum alloy metal is forced through a die of a specific cross-sectional area.

Aluminum extrusion can be compared to the squeezing of toothpaste from a tube. A powerful ram forces the aluminum through a die, which comes from the die's opening. It emerges in a shape same as that of the die and is pulled over a run out table. At an elementary level, the procedure of aluminum extrusion is fairly simple to understand.

The force applied can be compared to the force applied while squeezing a toothpaste out of a tube with one's fingers. As the tube is squeezed, the toothpaste comes out, taking the shape of the opening of the tube. The toothpaste tube's opening basically serves the same purpose as an extrusion die. Because the opening is a solid round, toothpaste emerges as a solid, long extrusion.

Heat Treating: Improving Mechanical Qualities

Alloys in the 7000, 6000, and 2000 series could be heat treated to improve their final yield stress and tensile strength.

To attain these improvements, piping is put into aging ovens where their aging procedure is sped up, and brought to T6 or T5 tempers.

How do their qualities change? Untreated (T4) 6061 aluminum has tensile strength of 241MPa/35000psi. Heat treated (T6) 6061 aluminum has tensile strength of 310MPa/45000psi.

After heat treatment, piping is finished.

Surface Finishing: Improving Appearance and Corrosion Resistance

Aluminum piping can undergo several finishing operations. The two major reasons to choose a finishing method is they improve the appearance of the aluminum and improve its corrosion properties.

For instance, the operation of anodization thickens the material's naturally occurring oxide coating, enhancing its resistance to corrosion and also making the material more wear resistant, enhancing surface emissivity, and offering a porous surface which can accept different colored dyes.Other finishing procedures like powder coating, sandblasting, painting, and sublimation (to make a wood look), can be done as well. There are many fabrication choices for extrusions.

Differences between Drawn vs. Extruded Aluminum

Drawn Aluminum Process

The drawn aluminum tubing process happens by having the aluminum pulled, or drawn into the die cavity, during which the aluminum undergoes what is called plastic deformation. Plastic deformation happens when the aluminum is stretched to achieve the desired shape. When stretching aluminum, it's important to pay close attention to the flexibility and elasticity of the metal. Stretch too much and it will become weak and brittle. Drawn aluminum is most often used to create products including pots, cans, tubes and other circular objects.

Extruded Aluminum Process

Extruded aluminum differs from drawn aluminum in that the formed shape is made by first heating the metal to a very high temperature until it is soft and malleable but not liquid. After the aluminum has been heated, it is then forced or pushed through a die. The extruded metal tubing product that comes out the other end will be molded by the die and shaped to the desired final product. To visualize the extrusion process, it can help to picture a tube of toothpaste. In this case, the toothpaste is shaped by the circular opening through which the toothpaste is pushed. After the aluminum has been extruded, it will begin to cool and harden. As it hardens, the finished extruded tubing product becomes strong and durable and will hold the desired shape.
Differences

While both processes can be used to create similar finished products, there are a few differences found between the two. These differences include:Product accuracy. Cold drawn aluminium tubes can be controlled to an accuracy of 0.02mm and are commonly used for telescopic tubes as well as precision instruments.

Cost. In general, the extrusion process tends to be cheaper than the drawn aluminum tubing process. This is because cold drawing aluminum often requires a larger collection of tools and materials to complete.

Products created. The extrusion and drawing processes will often be used to produce different types of products. For example, extruded aluminum can be used to make tubing, doors, window frames, brackets, and railings. Drawn aluminum will similarly be used to create tubing, in addition to products like cans and pots.

Shape of Aluminum Tubing & Piping

Metal tubing is highly rigid. This enables them to remain in shape. Most tubing utilized for smooth liquid flow comes with round cross-sections. However, there are also metal tubing with various shapes, like rectangular, oval, square, and circular. Some manufacturers also offer customized shapes. But they are more costly than regular metal tubing. Circular tubing is the most popular shape among these, as it provides constant distribution throughout the tubing.

Heat sink aluminium tubes, generally this type of tube is used in the lighting and optoelectronic industries to add heat sink fins to the inside and outside of the aluminium tube.

Drawbacks of Aluminum Tubing & Piping

Aluminum tubing doesn't have a great strength to weight ratio. Certain alloys of aluminum tube don't have the same corrosion resistance level like stainless steel. That's why aluminum tubes aren't a prevalent option for electrical cables.

Aluminum tubes need special procedures to be welded. Welding wears off from tooling, or more precisely, the aluminum tube oxide layer which forms upon it. It is more costly than steel.The first factor to consider when buying aluminum tubing is what industry it is to be used and what qualities are required in this industry. Light weight, durability, strong plasticity, low maintenance cost, high toughness, and corrosion resistance are features of aluminum tubing.
