Large Diameter Seamless Aluminum Tubes FAQ

Here are most of the questions related to large diameter aluminum seamless tubes. We hope you will find the answer to your question. If not, please leave us a message.

Do you produce seamless aluminum tubes and pipes for extreme pressures?2024-03-28T09:32:07+00:00

Yes, Fonnov manufactured the large-diameter aluminum seamless tubes and pipes for the extreme pressures that come with the applications – pressure vessels, LNG vessels, hydrogen storage in vehicles, etc. The aluminum alloys we use for the extrusions have the required combination of chemical, physical, and mechanical properties. Our quality control team is always keen to ensure that the dimensions, composition, and machenical characteristics of the extrusions are as designed. Ultimately, we have large-diameter aluminum seamless tubing that is reliable in high-pressure applications.

What are the common thicknesses for your large-diameter aluminum seamless tube and pipe?2024-03-28T09:26:20+00:00

Fonnov manufactures large-diameter seamless aluminum tubes with a variety of wall thicknesses to cater to different customer requirements. The biggest determinants for this wall thickness are the alloy, project requirement and the outside diameter of the tube or pipe. If you are looking for higher durability and strength, we would recommend you choose the thicker-walled seamless tube and pipe. There are times when the thinner tubes and pipes make more sense – when the need for lighter installations and enhanced flexibility is higher. We have countless wall thickness options so that the customer can always find the ideal option.

Can I use any alloy for a large aluminum seamless tube and pipe?2024-03-28T09:21:35+00:00

Yes, there are instances where the interchangeable use of different alloys is possible, but this depends on the project’s performance requirements. Remember that each alloy has specific pros and cons, but some projects may not be so specific. Any alloy may serve the purpose in that case. While these instances are possible, they may be rare where considerations such as weight, corrosion resistance, and material compatibility are important. The point is that you will usually need to first evaluate the specific requirements of a project before comparing the different material options for large-diameter aluminum seamless tubes and pipes.

Do the large-diameter seamless aluminum tubes and pipes require maintenance?2024-03-28T09:18:43+00:00

Yes, these items may require some form of maintenance, particularly in industrial applications where corrosion is likely to be a problem. Occasional inspection of the tubes and pipes for corrosion and wear is advisable to ensure that the system is safe and at optimal performance levels. In case there are possibilities of surface contaminants, you may want to gently clean the surface. For hydraulic systems and air separation equipment that may feature seals, consider adding some lubricant. The goal of these and other maintenance activities is to prevent/slow down wear of the aluminum seamless tubing for the safe and economical use of large-diameter seamless tubes and pipes.

How does the machinability of the different materials for these seamless tubes compare?2024-03-28T09:16:27+00:00

The different materials for the large-diameter aluminum seamless tube and pipe have varying machinability levels. This is because each of the materials has a unique blend of components, mechanical properties, and chemical properties. For instance, consider a comparison between alloys 7075 and 6061. Both are applicable for large-diameter seamless tubes and pipes but have different machinability levels. Due to its ductile nature, aluminum 6061 is easier to machine compared to aluminum 7075, which is harder and stronger. But the fact that an alloy is hard to machine doesn’t completely rule it out from a project. There are special machining techniques and tools to help machine such materials.

Can you machine the large seamless aluminum tube?2024-03-28T09:12:19+00:00

Yes, we provide 5-axis CNC machining and fabrication services for the seamless aluminum tube to add value to the products. We recognize the desire of the customer to get specific features and dimensions on the large-diameter tube and pipe, so we have this customization option. If you want to attain complex geometries with the CNC machining service, we offer that. Our experienced engineers are pleased to attend to your custom requests and always engage continually to deliver the most tailored machining solution for the large aluminum seamless tubing.

2024 Aluminum vs. 7075 Aluminum2024-03-01T06:52:00+00:00

If you are unsure which option between 2024 and 7075 aluminum is better, it is understandable. Both alloys are known for their high strength, so they could suit a project if that is the sole consideration.

But when it comes to specifics, things begin to change. For instance, if you are looking for an alloy with higher stress/stain resistance, then we would recommend the 7075 aluminum. However, use 2024 aluminum if the cyclic fatigue resistance requirements for your project are high.

The 2024 aluminum is mainly composed of aluminum, copper and magnesium. The 7075 aluminum is mainly composed of aluminum, zinc and copper.

They are all hard alloy, and widely used in aircraft parts. But the 2024 aluminum is not common for general industries.

Can I use 6061T6 instead of 7075T6?2024-02-29T02:59:00+00:00

Different aluminum alloy and temper is with different mechanical properties, as well as different requirement in application. Click How to Choose Aluminium Profiles: 7075T6 VS 6061T6 to see the differences of 6061T6 and 7075T6, which can help you to confirm the material that you need for production.

 

What is the max. width you can extrude?2023-12-05T03:13:45+00:00

The max. width that we can do depends on the exact profile shape. Please send us your CAD drawings for a brief check firstly.

The wider the cross-section, the larger the extrusion press is needed. Our largest capability is with width 750mm for some shapes. Many construction companies will be concerned about the maximum width that an aluminum extruder can do. For example, the width of the aluminum formwork usually needs to be at least 300mm.

In cooperation with top institutions in China, we offer and produce aluminum extrusions with a maximum section width of 1100mm. We are working with many famous transportation companies on large size aluminum extrusions.

Can you provide machining service for extrusion order?2023-05-04T04:13:17+00:00

We have an aluminum fabrication shop to provide CNC machining and fabrication service.
The material is not only aluminum extrusion products but also aluminum sheet panels. Please send us your CAD and 3D drawings for a quote.
