How to calculate the volume of rubber and plastic insulation pipe?
Rubber and plastic insulation board is one of the domestic hot-selling insulation products, and the aluminum foil rubber and plastic insulation board is further strengthened by the characteristics of the insulation material. Let us briefly introduce the advantages of Dukan rubber insulation board.
Advantages of composite aluminum foil insulation materials:
The waterproof layer is protected from thermal stress, ultraviolet light and other factors that damage the waterproof layer;
Excellent moisture resistance makes the composite foil insulation material have long-term stable thermal insulation performance and compressive strength;
Long-lasting thermal insulation, durability and building life;
In the future, the roof maintenance will not damage the materials, which is convenient and simple;
The use of high-efficiency insulation materials is more in line with the development direction of building energy-saving technologies.
Rubber and plastic insulation board is one of the domestic hot-selling insulation products, and the foil-coated rubber-plastic insulation board further enhances the characteristics of the insulation material.
How is the cube counted?
The formula is: (π R2-π r2)L Note: 2 is square, on the upper right.
Simplification is: (π R2-π r2)L = π (R2- r2) using a formula of middle school a2-b2=(a+b)(ab) R means the radius of the pipe plus the thickness of the insulation, r means the outer diameter of the pipe , where R = r + insulation thickness.
2r is the diameter d of the pipe. The final simplification is: π X (d + insulation thickness) X insulation thickness XL Note: π is 3.14, L is the length of the insulation pipe (meter).
How to calculate the cube number, but also pay attention to the unit must be unified into meters, the final result is the cube.
