Seamless Aluminum Pipe 2024/3003/5083/6061/7075

Seamless aluminum tube/pipe is made without welds. This gives it better strength, pressure resistance, and corrosion performance than welded pipes. Welded pipes, including ERW (Electric Resistance Welded), are made by rolling and welding metal sheets. They have a weld seam, which can be a weak point. Seamless pipes are extruded from solid billets. This creates a uniform structure with no welds. ERW pipes are cost-effective and common in low-pressure uses like fencing or furniture. However, they may not hold up well under high stress or corrosive environments. Seamless aluminum pipes are ideal for tough applications. They are widely used in aerospace, automotive, and fluid systems.

Extruded Seamless Aluminum Tube

Extruded seamless aluminum tube is a hollow cylindrical aluminum product made by direct extrusion through a reverse extruder without any welds. Compared with welded tubes, this kind of aluminum tube is stronger and more reliable in high pressure and structural applications.

Forged Seamless Aluminum Pipe

Forged seamless aluminum tube is a hollow cylindrical product produced by forging and extrusion process without welding, free of pores, sand holes, high surface brightness and precision, with the characteristics of high strength, good structural integrity and high reliability in critical applications.

Key Characteristics of Forged Seamless Aluminum Pipe

• No weld zone Stronger and more corrosion-resistant

• High mechanical strength Especially in T6 or T651 tempers

• Uniform grain structure Grain flow follows pipe geometry

• Pressure resistance Ideal for pressure-critical systems

• Good fatigue resistance Excellent for aerospace and structural use

Cold Drawn Seamless Aluminum Tube

Cold Drawn Seamless Aluminum Tube is an aluminum tube manufactured without welding and cold-worked through drawing, which improves dimensional precision, surface finish, and mechanical strength.The tube is pulled through a die and mandrel at room temperature. This process is ideal for high-tolerance and critical structural or fluid-carrying applications.

 Cold Drawn Seamless Tube vs Hot Extruded Seamless Tube

Application of cold drawn seamless aluminum tube

• Aerospace Hydraulic & fuel lines, structural supports

• Automotive Shock absorber tubes, steering columns

• Medical Prosthetics, surgical instruments

• Robotics & Automation Lightweight precision framing

• Industrial High-pressure gas lines, instrumentation

• Sports & Outdoor Bicycle frames, ski poles, arrows

Extra Larger Diameter Seamless Aluminum Pipe

Extra Large Diameter Seamless Aluminum Tubes refer to seamless extruded or forged aluminum hollow profiles with an outer diameter usually above 200 mm and up to 1500 mm, a wall thickness of 25 mm-300 mm, and a length of up to 18 meters, used in high strength, pressure or structural applications where the integrity of the weld seam is critical.

Applications of Extra Larger Seamless Aluminum Pipes

• Aerospace Rocket motor cases, satellite tanks, airframe cylinders

• Marine & Offshore Ballast systems, fluid handling lines, structural arms

• Oil & Gas / LNG Cryogenic tanks, high-pressure tubing

• Nuclear & Defense Radiation-resistant piping, weapon systems

• Heavy Equipment Hydraulic cylinders, boom arms

• Architecture & Transport Bridge components, subway infrastructure, monorails
