Brief Construction Instructions
1 First , remove oil and wastewater from the surface of the steel pipe, preheat and dry the pipe, and then perform shot blasting to the Ss2.5 level specified in GB/T8923. Grade; anchor pattern depth: 40-100 μm Blow away dust and abrasive from the surface of the steel pipe.
2. The preheating temperature of the steel pipe is generally controlled at 230-260℃, but can be adjusted according to the actual construction conditions.
3 Electrostatic spraying is used, with a coating thickness of ≥250 μm for the general grade base coat . Surface layer ≥370 μm The reinforced base layer is ≥300 μm , and the top layer is ≥500 μm .
4. The construction environment should be dry and clean.
5. The anti-corrosion powder should be opened as needed, and any remaining product should be sealed promptly to avoid dust contamination and moisture.
Packaging and Storage
This product is a powdered solid material, packaged in a 25 kg cardboard box . Avoid exposure to direct sunlight and rain, and keep away from fire. The maximum stacking height should not exceed [a certain limit]. More than five layers are required to avoid pressure and ensure the product is airtight to prevent clumping and moisture absorption. Storage temperature should be below 23°C.
