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 selection of thermal insulation aluminum coil should pay attention to cost performance:
1. We should not only pay attention to the price when purchasing thermal insulation aluminum coils, but also pay attention to the products based on the price. After all, the price is the same as the goods. We must pay attention to the products whose price is too low to avoid big losses due to greed. Of course, under the same circumstances, we should look at the price, and choose the cost-effective enterprise is our final choice.
2. The thermal insulation aluminum coil shall be compared with three stores:
There are so many products in the market. If you want to select the products you are satisfied with, it is a good way to compare the products. Different enterprises produce different products. We can find which one we need through product comparison. When comparing products, we should not only look at the products and prices, but also understand their services and brands. Only by understanding can we truly and effectively select the products.
3. Pay attention to details when purchasing products:
We should not only focus on the surface of the product, but also pay attention to the comparison of details. We should understand all aspects of the production process and specific performance of the product. If the process of thermal insulation aluminum coil looks very rough, there may be problems with the aluminum coil. We need to further understand and test the products to avoid losses caused by buying unqualified products.
