First of all, I will give you the meaning of enhanced anticorrosion. Polyethylene tape anti-corrosion is divided into three levels: general level anti-corrosion, anti-corrosion layer thickness ≥0.7mm; Enhanced anti-corrosion, anti-corrosion layer thickness ≥1.0mm; Special reinforced anticorrosion, anticorrosive layer thickness ≥1.4mm. Secondly, strengthen the construction plan of anti-corrosion. Anticorrosion layer thickness ≥1.0mm, become the enhanced anticorrosion.
If party A or the design drawings do not make detailed requirements for the product specifications. I suggest you adopt the following construction plan. A. Use primer, anticorrosive belt, protective belt anticorrosive structure. Apply a primer to the outside of the pipe and wrap around a 0.5mm thickness of inner tape and wrap around a 0.5mm thickness of outer tape. Total thickness ≥1.0mm. B. Anticorrosive structure with primer and anticorrosive adhesive tape. A primer is applied to the outside of the pipe and a 0.5mm thick layer of anticorrosive adhesive tape is wrapped around it and overlapped 50% to 55%. Total thickness ≥1.0mmc. Use primer, compound polyethylene adhesive tape. Apply a primer to the outside of the pipe, then wrap a 1.0mm thick layer of anticorrosive adhesive tape around it and lap it 1 to 2 cm. The total thickness is greater than or equal to 1.0mm. Again, the thickness of polyethylene adhesive tape is selected according to the above three construction schemes. The width of the tape can be determined according to the actual construction pipe diameter.
