The difference between aluminum hoses and aluminum pipes

1、 What is an aluminum hose?

Aluminum hoses refer to packaging materials made from pure aluminum sheets and can be used for filling cosmetics, toothpaste, glue, pigments, and other ointments, also known as aluminum hoses, metal hoses, packaging aluminum tubes, etc. Its biggest feature is that after being squeezed, the tube body will collapse, making it difficult for air to flow into the inside of the hose, making it less prone to oxidation or pollution of the contents.

2、 What is an aluminum tube?

Aluminum tube refers to a metal tubular material that is extruded from pure aluminum or aluminum alloy and becomes hollow along its longitudinal length. It is a type of non-ferrous metal. According to appearance, there are square tubes, circular tubes, patterned tubes, irregular tubes, and universal aluminum tubes; According to the extrusion method, there are seamless aluminum pipes and ordinary aluminum pipes classified according to accuracy, ordinary aluminum pipes and precision aluminum pipes classified according to thickness, and ordinary aluminum pipes and thin-walled aluminum pipes.

Aluminum hoses and aluminum pipes, due to their overly similar names, are often mistaken for the same material. There is actually a big difference between the two.

3、 The difference between aluminum hoses and aluminum pipes

（1） The production processes of the two are different

1. After stamping the aluminum hose into a tubular shape, the thread of the pipe mouth needs to be trimmed, and the pipe mouth and tail need to be cut evenly before being sent to the oven for annealing to soften the aluminum pipe. This is the fundamental step in the production of all aluminum hoses. There are multiple processes that can add value to aluminum hoses, such as internal spraying, primer, printing, and tail glue, but these processes can be selected according to customer needs and are more flexible.

2. Aluminum pipes are made of high-strength hard aluminum that can be heat treated for strengthening. It can be molded after annealing, just quenching, and hot state. After quenching and cold work hardening, aluminum pipes have good machinability; But if it is not good during annealing, the corrosion resistance of the aluminum pipe is not high. Anodizing and painting methods or adding an aluminum coating on the surface can be used to improve the corrosion resistance of the aluminum pipe.

（2） The surface treatment methods of the two are different

1. The surface treatment methods of aluminum hoses mainly include color spraying, primer application, offset printing, silk screen printing, heat transfer printing, hot stamping, and other methods.

2. There are two surface treatment methods for aluminum pipes. One is chemical treatment: oxidation, electrophoretic coating, fluorocarbon spraying, powder spraying, and wood grain transfer printing; The second is mechanical processing methods: mechanical wire drawing, mechanical polishing, and sandblasting.

（3） The scope of application of the two is different

1. Aluminum hoses are generally used for filling cosmetics, hand creams, eye creams, nail glue, glue, lubricating grease, car repair glue, hair dye, toothpaste, pigments, etc. They are common small packaging materials for household products;

2. Aluminum tubes are widely used in various industries, such as automobiles, ships, aerospace, electrical appliances, agriculture, mechatronics, home furnishings, etc. They are large-scale decoration materials.

4、 Summary

1. Although there are many differences between aluminum hoses and aluminum pipes, both are packaging materials produced from aluminum materials.

2. As is well known, aluminum materials are not easy to rust, have good ductility, sealing properties, and are easy to recycle, without causing serious pollution or damage to the environment.

3. In the current era of continuous promotion of environmental protection and green concepts, it is necessary to quickly change the traditional production methods that consume a lot and damage the environment, and use recyclable and biodegradable packaging materials. This is also one of the important factors that packaging aluminum tubes and aluminum tubes are becoming increasingly popular!
