一分彩How to calculate the amount of anti-corrosion tape used in anti-corrosion projects
一分彩In the pipeline anticorrosive construction process, the anticorrosive tape we used is polyethylene preservative tape. In the process of use, it is necessary to accurately calculate the amount of anticorrosive tape. According to the thickness of the tape and other standards, the calculation method of the amount of polyethylene tape can refer to the standard.
1. An inner belt with a thickness of 0.5mm and an outer belt with a thickness of 0.4mm can be used. The inner tape is wound with 50% overlap (corresponding to the thickness of the two-layer inner tape: 0.5mmx2 = 1.0mm), and the outer tape is wound with 10% overlap and the thickness is 0.4mm. The total thickness of the anti-corrosion layer after anti-corrosion construction is: 0.5mmx2 0.4mm = 1.4mm.
2. An inner belt with a thickness of 0.5mm and an outer belt with a thickness of 0.55mm can be used. The inner tape is overlapped with 50% overlap (equivalent to the thickness of the two-layer inner tape: 0.5mmx2 = 1.0mm), and the outer tape is overlapped with 10% overlap and the thickness is 0.55mm. The total thickness of the anti-corrosion layer after anti-corrosion construction is: 0.5mmx2 0.55mm = 1.55mm.
3. Inner and outer belts with a thickness of 0.4mm can be used. The inner and outer belts can each be overlapped by 50%, and according to the prescribed winding method, the design requirements of the total thickness of the anticorrosive layer greater than 1.4mm can be achieved: the inner belt 0.4mmx2 and the outer belt 0.4mmx2 = 1.6mm. (That is to say, the thickness of the adhesive tape is only required to be close to a quarter of the total thickness of the anticorrosive layer required by the design. Because the inner tape and the outer tape are each overlapped by 50%, it is equivalent to a total of four layers of anticorrosive tape.
4. According to the above tape specifications, you can calculate the tape area of various thickness specifications for the surface area per square meter of steel pipe to reach the specified corrosion resistance level. Then calculate the total area of the steel pipe for this anticorrosion project (diameter X 3.14 X total length of the steel pipe).
一分彩 5. After determining the total area of various specifications of tape required for anticorrosion engineering, the required weight of various specifications of anticorrosive tape can be calculated according to the following tape density (weight of tape per square meter):
0.4Thickness of 0.4mm tape: 0.5kg / sqm;
0.50.5mm thick tape: 0.6kg / sqm;
0.55mm thick tape: 0.66kg / sqm;
0.8Adhesive tape with thickness of 0.8mm: 1.0kg / m2.
一分彩In addition, during winding construction, whether using manual winding, manual mechanical winding, manual winding machine winding, and mechanical transmission winding, the anticorrosive tape must have a certain tension, that is, a certain tension (generally, the tension is 10 -20N / CM is appropriate) for winding construction.
If you have difficulty with the amount of anticorrosive tape, you can contact the manufacturer. In general, polyethylene adhesive tape manufacturers have various thicknesses of inner and outer tapes, which can meet the requirements of the total thickness of various reinforced anticorrosion. As long as you tell the factory your required anti-corrosion grade and the total thickness of the anti-corrosion layer, you will choose the appropriate inner and outer tape and thickness. If you tell the diameter and length of the steel pipe, you can calculate the inner and outer required for you at the same time. Band width specifications and tape quantity (Because the width of the tape is different according to the diameter of the steel pipe and the winding construction method, the amount of tape is related to the overlap width when winding).
It should be particularly noted that the total thickness of the anticorrosive layer of reinforced anticorrosion is not the thickness of a single layer of tape, but the total thickness of the anticorrosive layer after the inner and outer tapes are laminated after cold-wound anticorrosion construction (three or four layers of tape Total thickness).
