China Aluminum Industry Network: The aluminum tube market in China holds great potential, but it also brings challenges such as the prevalence of counterfeit products. To protect consumers from being deceived and to avoid losses, we are here today to share four simple and effective methods to identify genuine aluminum tubes and related products.
First, carefully examine the surface and internal structure of the aluminum tube, and use your hands to check its quality.
1. Genuine aluminum pipes typically have clear, high-quality printing with imported codes. The markings, including trademarks, manufacturers' names, addresses, and contact numbers, are all clearly visible and accurate. In contrast, fake aluminum tubes often use low-quality printing presses, resulting in blurry or unclear text. Their manufacturer information, logos, and other details may be missing or incomplete.
2. Authentic aluminum tubes are made from premium raw materials and undergo precise manufacturing processes. The inner and outer surfaces are smooth without any blemishes or uneven spots. On the other hand, inferior products may show signs of poor craftsmanship, such as rough surfaces or irregularities.
3. The thickness of the aluminum-plastic pipe and the aluminum strip should be uniform, and the bonding between the layers should be strong. High-quality products meet national standards for both material thickness and structural integrity. Counterfeit products, however, often have inconsistent wall thicknesses, thinner aluminum sheets, and noticeable gaps at the seams.
Second, you can test the pipe by lighting it with an open flame. True aluminum-plastic pipes are usually welded using advanced techniques like ultrasonic or hydrogen arc welding, resulting in a tight joint. When burned, the aluminum parts will not fall off. However, fake or substandard products often have loose joints and may show aluminum flakes when exposed to fire.
Third, use a pipe cutter to cut a small section of the aluminum tube and manually peel away the aluminum layer and the PE (polyethylene) layer. Genuine aluminum-plastic pipes are made up of a five-layer composite structure, with the aluminum and PE layers firmly bonded together. These layers are difficult to separate by hand. In contrast, fake products often have weak adhesion between the layers, making them easy to peel apart.
Finally, you can use a small pressure pump to test the pressure resistance of the aluminum tube. High-quality aluminum-plastic pipes are designed to withstand high pressure during testing, meeting or exceeding national safety standards. However, counterfeit products tend to fail under pressure tests, as they are unable to meet the required performance levels for safe use.
By following these four simple steps, you can significantly improve your ability to distinguish between real and fake aluminum tubes, ensuring that you make informed and safe purchasing decisions.
