Instruction of Drawn Aluminium Tube/Profiles

Precision drawn aluminium tubes are the lightweight solution for standard heat exchangers manufactured with the mechanically expanded round tube, flat oval tubes, and other shapes of the tube as customized specification.

The high-precision drawn aluminium tube (also called aluminium cold drawn tube) widely used for heat exchanger, including aluminium round tube, internal thread tube (inner grooved tube), seamless collector tube (header pipe), old drawn aluminium tube, seamless drawn aluminium tube, capillary tube, peanut tube, etc. It is the key material for terminal products, such as home and commercial air conditioning evaporator and condenser, automobile air conditioning evaporator, radiator condenser, water tank, etc.

Applications of Drawn Aluminium Tube

  1. HVAC&R: air conditioner, refrigeration, and another cooling system, (heat exchanger, evaporator, condenser, air cooler, water tank)
  2. Automotive: connection tubing, car engine manifolds
  3.  Precision equipment
  4.  Solar thermal
  5.  Other industrial applications

Drawn Aluminium Tube Key Features

● Lightweight

● High heat transfer efficiency

● Easy to form and bend

● Low volume – high quality

● Corrosion resistance

● High precision and tight tolerances

● High surface quality

Marking and packaging of Drawn Aluminium Tube

The packaging of our products (eg. weathered corrugated steel, weathering corrugated steel,corten steel columnl,hot rolled stainless steel plate) ensures that they will not be damaged during transport. For export purposes, the usual export packaging is done in wooden crates or crates. All hr sheet metal, plates and coils are marked with a logo (company mark), grade, size and batch number. On request, we can customise the marking on the product,such as spcc cold rolled steel.

Quality Control of Drawn Aluminium Tube

To get good quality, we must strictly control each step. 

● Raw material: we produce aluminium bar by ourselves, and detect each batch, ensure that the aluminium bar is pure, free of impurities, and the chemical composition meets customer requirements.

● Drawing and tooling: the importance of tooling is to ensure dimensional accuracy, through cold drawing to get high precision of dimension and tolerance. 

● Zinc coating: the tube with zinc spraying can greatly improve the corrosion resistance of aluminium tubes.

● Annealing: through annealing, the tube will get better elongation and better bending performance.
