High-temperature paint construction process of SSAW steel pipe: First, the surface of spiral welded pipe material should be degreasing, rust and dirt treatment before construction to improve the adhesion of the paint film. The humidity of the metal surface should be 3°C higher than the dew point during construction.

The second is to stir the paint evenly before use, which can be carried out by conventional methods such as brushing and spraying. When spraying, a high-temperature special thinner must be used, the dilution amount is 5-15% (based on the paint weight), the nozzle diameter is 1.5-2.0mm, and the air pressure is 0.3-0.4MPa.

Finally, it is recommended to brush or spray 1-2 procedures for SSAW steel pipe.
