Aluminum Perforated Tube Ideal for High Strength-To-Weight Applications

Aluminum perforated tube is extensively used as screens, filters, shields and guards of engineering, construction and material handling industries. It is especially suitable for low-temperature applications when its strength increases and ductility retains. However, when its working temperature reach 400 °F, aluminum tube tends to lose some strength.

One advantage of using aluminum perforated pipe depends on its ideal corrosion resistance and strength-to-weight ratio. For some applications, weight should be kept in a low level to ensure smooth operation. Under this condition, aluminum tubing is the best choice. It not only provides enough strength but weight less than other metals like stainless steel or mild steel.

Application:

Perforated pipe is used in filtration systems, such as water filter pipe, petrochemical refining, water wells, mining & mineral processing, filter of automobiles internal-combustion engine, medicine, tea filter, air filter, drilling.

Perforated pipe is applied to exhaust system such as, perforated exhaust pipe.

Perforated pipe with function of support and protection is widely used in underground cable pipe protective, inner duct communication pipe protective, water drainage or water supply pipe protective or sprinkler irrigation pipe, drilling.

Perforated filter pipe with good sound insulation is applied to silencer.

Margin of perforated pipe refers to the distance from the end of the pipe to the perforated area which is parallel to the end edge. There are three options for your perforated metal tubing. You can specify the option when you order.

Margin Options:

Safe side margin: Perforated holes are not on or over the edge. There is some distance between the edge to the perforated area.
No margins - There are perforated holes on the edge of the pipe.
Intermediate margin - Unperforated area exists inside the perforated sections not the edge. It is designed to achieve particular appearance or design.

Commonly Perforated Aluminum Types:

1100 (Non-Heat-Treatable Alloys)
This commercially pure, low-strength alloy has excellent corrosion resistance and satisfactory anodizing and coating finishes. It is unmatched by any other commercial aluminum alloy in workability.

3003 (Non-Heat-Treatable Alloys)
The most widely used general-purpose alloy because of its good corrosion resistance, moderate strength, formability, and weldability. This alloy may show some slight discoloration when anodized, but reacts well to other coating finishes.

5005 (Non-Heat-Treatable Alloys)
Comparable to 3003 in strength and formability, this alloy has superior finishing characteristics, making it much better for anodizing. Excellent corrosion resistance and weldability, but rates below 1100 and 3003 for machining.

5052 (Non-Heat-Treatable Alloys)
A versatile high-strength alloy with good forming characteristics and excellent corrosion resistance. Although easily welded, it is not recommended for brazing and soldering applications. Anodized coatings may take on a yellowish tint if applied too thick.

2024 (Heat-Treatable Alloys)
An age hardening, high-strength alloy with nearly twice the strength of 5052 and fair corrosion resistance. Alclad 2024 provides improved corrosion resistance. Anodized coatings may take on a yellowish tint if applied too thick.

6061 (Heat-Treatable Alloys)
A high-strength alloy that has very good corrosion resistant, finishing, welding characteristics. Anodized coatings may take on a yellowish tint if applied too thick.

7075 (Heat-Treatable Alloys)
Developed for aircraft applications, this is one of the highest strength, commercially available alloys. It has fair corrosion resistance and machinability. Alclad 7075 provides improved corrosion resistance. Anodized coatings may take on a yellowish tint if applied too thick.
