Technical requirements for aluminum sheet
The gap is required to be tight; The multi-layer insulation must be caulked, and the caulking distance shall not be less than 300mm. The axial butt joints of the inner and outer layers of insulation products shall be staggered by 25 °. The thermal insulation materials shall be bound firmly, close to the equipment or pipe wall, and the surface of the thermal insulation layer shall be flat and beautiful.
2. When the pipe insulation aluminum coil is constructed by binding method, each piece of arc-shaped tile shall be bound with at least two galvanized lead wires or bands, and the spacing shall not be greater than 500mm.
3. The longitudinal joint position of the pipeline shall not be arranged within 55 ° of the vertical center line of the pipeline.
4. The seam width of thermal insulation products is generally not more than 6mm. And attention shall be paid to staggered joints during construction. When the insulating layer is sealed with adhesive tape, the joint can be good.
Characteristics of thermal insulation aluminum coil
1. The aluminum coil is light in weight. When the price per square meter is calculated, steel and aluminum are almost equal.
2. The aluminum coil is easy to process and form, and the construction is convenient and fast, which will reduce the labor intensity of the construction personnel.
3. The aluminum coil is beautiful, and the aluminum skin is used for thermal insulation and external decoration. The bright visual effect is very good, and the pipeline is wrapped with bright style!
4. The aluminum coil has a long service life. Because of its corrosion resistance, it will not corrode for more than 20 years.
5. The aluminum coil has high recycling value. The iron sheet will corrode and rot after several years of use, and there is almost no recycling value. However, the aluminum coil has much higher furnace value after recycling due to its corrosion resistance. At least 80% can be recycled.
6. Aluminum coil is widely used in oil refinery, power plant, chemical plant and other thermal insulation projects!
The representative 1000 series aluminum plate is also called pure aluminum plate. Among all the series, 1000 series belongs to the series with the largest aluminum content. The purity can reach more than 99.00%. Because it does not contain other technical elements, the production process is relatively simple and the price is relatively low. It is the most commonly used series in the conventional industry. Most of the 1050 and 1060 series are in circulation in the market. The minimum aluminum content of the 1000 series aluminum plate is determined according to the last two Arabic numerals. For example, the last two Arabic numerals of the 1050 series are 50. According to the international brand naming principle, the aluminum content must reach 99.5% or above. The aluminum content of 1050 aluminum alloy reaches 99.5%. Similarly, the aluminum content of 1060 series aluminum plate must reach more than 99.6%.
