Internal Coating Special Coating

Suitable for anti-corrosion coating on the inner wall of steel pipelines for gas and water transmission.

1 First , remove oil and wastewater from the surface of the steel pipe, preheat and dry the steel pipe, and then perform shot blasting and sandblasting treatment to GB/T8923. Ss2.5 as specified in the document class: Anchor pattern depth: 40-100 um : Blow away dust and abrasive from the surface of the steel pipe.

2. The preheating temperature of the steel pipe is generally controlled at 230-240℃, but it can be adjusted according to the actual construction conditions.

3 Electrostatic spraying is used, with a coating thickness of 300-500 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 absorption.

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]. Layer the product through five layers to avoid pressure, ensure product density, and prevent clumping and moisture absorption. Store at a temperature below 23°C
