At present, the processing range and production technology of aluminum and aluminum alloy at home and abroad are growing rapidly, reaching a relatively high level. Because aluminum and aluminum alloy have many good physical characteristics, they have occupied a very important position in the pipeline industry.

Specifically, aluminum is a light metal with a small specific gravity, as long as it is 1 / 3 of iron, and the melting point is 658 ℃. It has excellent thermal and conductive functions, non-magnetic and good plasticity. Because of its poor strength, soft strength and easy deformation, aluminum alloy is made of manganese, copper, magnesium, silicon and other elements in pure aluminum, making it strong and not easy to deform. It has become the most widely used non-ferrous metal layout material in the industry.

Aluminum is an active metal, which will be quickly linked with oxygen in the atmosphere, forming a solid aluminum oxide film on the surface. This film can not only prevent the inner layer of aluminum from being continuously linked with oxygen and play a protective role, but also have a strong resistance to many corrosive media (such as 98% concentrated nitric acid, ammonium bicarbonate, urea, vinegar wax, formaldehyde, hydrogen peroxide, etc.). The higher the purity of aluminum, the stronger the corrosion resistance.

Because of its good corrosion resistance, the aluminum alloy pipes manufactured are widely used in the chemical industry and food industry.

Because the mechanical function of aluminum under high temperature is still outstanding and even improved, aluminum alloy pipes can be used in cryogenic assembly, liquid dressing device, air separation assembly, food freezing and other pipeline systems, and can also be used in pipeline systems without iron ion purification medium.

The aluminum alloy pipeline system is made of high-quality aluminum alloy material, coated with epoxy resin, and subjected to special treatment inside the pipeline to prevent the pipeline from being oxidized, make its slippery inner surface never erode, and avoid leakage to achieve the goal of energy saving. Aluminum alloy pipes can transport compressed atmosphere, vacuum, nitrogen, inert gas, etc., and are often used in electronics, paper making, furniture, aerospace, automobile parts, machinery and equipment, food manufacturing, textile printing and dyeing, new energy and other manufacturing industries, and also in the highly demanding medical manufacturing industry.
