Product Description
Advantages & Applications
Company

Aluminum High Frequency Welded Tube is also called Aluminium HFW Pipe. It is manufactured by forming a flat strip of aluminum into a tubular shape and then joining the edges by a high-frequency welding process, and seam welded without the use of any filler material. The welded tube is then adjusted in size until reaching the exact size and tolerances.
The aluminum high frequency welded tube is a kind of composite tube. The main difference between extruded and drawn tubes is the possibility to have a weldable layer material of different aluminum alloys. Generally, the core material is 3003 and the clad weldable alloy is 4343 or 4045. It is widely used in tubes for heat exchanger production to enable the furnace or flame to braze and to give sacrificial corrosion resistance.
In addition to the welded tube with a weldable alloy, we also supply another kind of aluminum composite tube, which is an al-al composite drawn seamless tube with multi-layer material, mainly used as a condenser header pipe.
Our aluminum high frequency welded tubes are manufactured with high precision and extremely low tolerance to meet the customer’s specific requirements, and welded tubes can be created in a variety of different sizes and shapes from a wide range of alloys. The most common shapes are round, flat, oval, rectangular, and square, thin-walled or thick-walled aluminum tubes are also available. The general standard inventory sizes and customized specifications are available for inquiry.
Production process

Options of Aluminum High Frequency Welded Tube

Applications of Aluminium High Frequency Welded Tubes
The aluminum high frequency welded tubes are ideal for heat transfer applications where weight and space are design concerns, including in HVAC units, automotive heat exchange systems, manifolds, evaporators, and condensers. It can also be applied in electrical conduits and general tubing for plumbing and construction

Automotive Applications of Aluminium High Frequency Welded Tube
● Flat oval aluminum welded tubes for radiators.
● Round aluminum welded tube for condenser headers.
● Rectangular welded tubes for charge air coolers (CAC tubes).
● Thick-walled rectangular aluminum welded tube for oil coolers.
● Internal enhancements such as dimples or turbulators increase heat transfer.
● Headers/manifolds for mobile A/C condensers and battery coolers.
● Small-diameter welded aluminum tubes for connector lines.

HVAC/R Applications
● Used as aluminum headers/manifolds for stationary condensers
● Inner-groove welded tubes with high heat transfer performance
● Mechanically expanded heat exchangers

Industrial Applications
● For industrial applications, where strength and formability are important factors, high-strength materials available for high-pressure applications, such as 5xxx-series alloys with the advantages of high strength and good dimensional stability can be utilized.
● Electrical conduits.
● Ladders and scaffolding.
● Special aluminum welded tubes for orthopedical equipment, sports adventure equipment, garden, and forestry.
● Welded tubes with high resistance to corrosion for the desalination industry.
