Insulation aluminum jacketing coil for pipeline anticorrosion

Mar 06, 2022

At present, the commonly used insulation aluminum jacketing coils are divided into three types: 1 series pure aluminum coil, 3 series aluminum manganese alloy, and 5 series aluminum magnesium alloy. Among them, 1 series is pure aluminum, the price is the lowest, and the municipal pipe and roof insulation are mostly used. The 3 series aluminum coil has higher hardness and is used in the outer packaging parts, such as tanks, mechanical parts, refrigerators, refrigeration parts of air conditioners, etc.; The highest price of aluminum coils is an excellent rust-proof aluminum, which is used in special environments such as maritime, marine, chemical, and electric power.
As the output continues to increase and the price drops, the aluminum coil gradually replaces the iron and zinc skin and becomes the main material for pipe insulation. At present, thermal insulation aluminum coil has been widely used in many industries such as electric power, chemical industry, municipal heating, nuclear power, etc.



Insulation aluminum coil features:

1. The aluminum coil does not rust. The biggest reason for companies to abandon iron for aluminum is because aluminum coils do not rust with water. Iron and zinc skin are not corrosion-resistant, exposed to the natural environment, long-term wind and sun, and soon rust and weathering; while aluminum coils do not rust with water, the service life is much longer than iron and zinc skin.
2. The aluminum coil is more beautiful. Aluminum is a kind of silver-white metal. It can be processed to have a high degree of smoothness and is very beautiful. After aluminum is processed into aluminum coil, it has bright silver-white metallic luster. It is insulated with aluminum coil. After the project is finished, the style is uniform and beautiful. Bright landscape.
3. The aluminum coil has a long service life. Because iron and zinc skin are easy to rust, after a few years of use, they will gradually corrode and peel off. Enterprises must re-construct every few years; while aluminum coils have a much longer service life than iron sheets, companies often only need to do it once. Construction, you can sit back and relax.
4, aluminum coil can be preserved. The recovery price of iron and zinc skin is very low. The price of scrap iron is only a few tenths of that when it was originally purchased. There is no recycling value after rusting. The recyclability of aluminum is high because aluminum does not rust. Even if it has been used for more than ten years, its price can reach more than half of the spot aluminum coil, which has a strong value-preserving function.
Therefore, the thermal insulation aluminum coil is suitable for pipeline insulation, power plant pipeline insulation, chemical plant pipeline insulation, and a variety of insulation options.
