Identification of authentic aluminum tubes
ã€China Aluminum Industry Network】 China's aluminum tube market has a very broad prospect, which also brings bad atmosphere to the whole market. In order to avoid consumer losses, today we will teach you simple four measures to identify authentic aluminum tubes and Products.
First, look through the surface of the aluminum tube and the inside and outside the surface and Other observation, hand touch identification.
1. The surface of genuine aluminum pipe is generally printed with imported coding. Its writing is clear, and the general marks such as trademark identification, manufacturer, address and even telephone are all clear and true; the surface of counterfeit and fake aluminum pipe is printed on ordinary printing presses. , The writing is vague, its manufacturers, logos, etc. are generally unknown or not marked.
2. The authentic aluminum tube is made of high-quality raw materials, and its process accuracy is high. The surface and inner layers are smooth and smooth, and there is no mottled spot. The shoddy aluminum-plastic pipe products are relatively poor due to cutting corners.
3. The thickness of the aluminum-plastic pipe and the aluminum strip are even and the aluminum pipe is tightly bonded. The quality and thickness of the pipe and the aluminum strip can meet the national standards; while the shoddy products have large deviations in the wall thickness, and the aluminum sheet is thinner. , And its aluminum tube lap at the gap.
Second, the use of open fire to light the pipe. True aluminum-plastic pipes are welded by ultrasonic welding or hydrogen arc welding. The interface is very tight. After the fire ignites the pipe, the aluminum pieces will not fall off. The fake aluminum pipe and other combination pipes The aluminum sheet is not welded and its interface is not tight. After the ignition, aluminum flakes will appear.
Third, the scissors cut the aluminum tube into a strip shape by using a pipe cutter, and peel the aluminum tube layer and the PE layer by hand. The real aluminum plastic pipe is a 5-layer composite structure, and its aluminum layer and the PE layer are closely attached. The aluminum pipe layer and the PE layer are not easily detached by hand; and the inferior and inferior products do not closely adhere to the aluminum layer and the PE layer because of cutting corners. Easily peel off.
Fourth, measure the use of a small pressure pump to test the pressure resistance of aluminum tubes. Aluminium-plastic tubes have a high pressure in the blasting process and generally can meet or exceed the requirements of the relevant national regulations. However, shoddy products have generally lower or lower pressures in blasting, and it is difficult to meet the requirements for use.
