The Difference Between Aluminum Thin Wall Pipe and Thick Wall Pipe

Aluminum alloy pipes are widely used in industry and construction, and there are obvious differences between thin-walled pipes and thick-walled pipes in terms of wall thickness, strength, weight, cost, performance and use.

Understanding the different characteristics of aluminum alloy thin-walled and thick-walled pipes can help you make informed decisions when designing and selecting materials to meet project needs and achieve optimal performance.

Performance differences

Manufacturing process difference

Thick-walled pipes are relatively easy to process, but the influence of wall thickness also needs to be considered and appropriate processing techniques selected to ensure their internal and external quality.

Thin-walled tubes are more difficult to process because they are easily deformed due to their thin walls. Higher-precision processing equipment and technology are required in processes such as extrusion and stretching to ensure their dimensional accuracy and surface quality.

Application areas and aluminum tube selection

Thin-walled tubes generally have a high strength-to-weight ratio and are suitable for applications requiring lightweight design, such as in the aerospace and automotive industries. Its lightweight characteristics enable it to meet structural strength requirements while reducing the overall weight.

Thick-walled pipes are usually used in engineering structures because of their large load-bearing capacity and are suitable for applications that require higher strength and pressure resistance, such as building support structures, mechanical equipment and other fields.

※ 8 Tips for the production of thin wall aluminum tube pipe

• When sampling, it is necessary to check according to the drawing size, strictly control the wall thickness of the aluminum profile, and use a vernier caliper to check whether it is qualified.
• The molds are polished and improved to improve the surface quality of the aluminum profiles, and nitriding treatments are performed regularly to ensure sufficient preparation for the next production.
• Adjust the level of the discharging table and cooling bed before production to prevent the aluminum profiles from being scratched during movement and ensure product quality.
• Control the temperature during the extrusion process, including the temperature of the aluminum billet, container and mold, and adjust the speed according to the extrusion surface quality and process progress to ensure a smooth product surface.
• Pay attention to the surface quality and initial runout from the discharge port to the cooling bed to avoid defects such as scratches on the bottom surface, and adjust the height of the support wheel to prevent deformation of the aluminum profile.
• Reasonably arrange the spacing between aluminum profiles on the cooling bed to avoid collisions and scratches and ensure product quality.
• Control the straightening and sawing processes to avoid deformation and surface defects of aluminum profiles, and pay attention to cleaning aluminum chips to keep the product surface clean.
• Use special lifting tools to install the profile frame, keep intervals and observe the end quality to improve surface quality and avoid scratches, and ensure ventilation and aging conditions of the aluminum profile.
