Subsea coatings need what equipment to produce?

Subsea coatings are critical to protecting equipment from the harsh marine environment, including corrosion, abrasion and biological growth. The selection and application of these coatings require specialized production equipment and techniques to ensure optimal performance.

Main production equipment

1. Surface preparation tools

Sandblasting equipment: Essential equipment for cleaning surfaces before coating application. This includes a variety of abrasive media to achieve the necessary surface profile.

Power tools: Grinders and sanders can be used to prepare surfaces, especially hard-to-reach areas.

?

2. Coating Application System

Spraying Equipment: High-pressure spray systems are often used to spray liquid coatings to ensure even coverage. This includes airless spray guns that can handle high-viscosity materials.

Brush and Roller Application Tools: Brushes and rollers are suitable for smaller or intricate areas where spraying is not feasible.

?

3. Curing Equipment

Oven or Heat Lamp: Used to cure coatings that require heat to set properly, especially important for high temperature resistant coatings.

UV System: UV curing systems are essential for coatings that cure through UV radiation.

?

4. Mixing and Storage Equipment

Marine Coatings Dispersers: High shear mixers are utilized for blending the components of multi-part coatings, like epoxies, before application.

Epoxy Coatings Storage tanks: Proper storage solutions are essential to maintain the quality of coating materials before use.

5. Grinding equipment

As people's environmental awareness increases, water-based paints will gradually replace all traditional oil-based paints. Graphene oxide is introduced into composite coatings as a nanofiller for modification, and the performance of graphene oxide-modified composite coatings is systematically studied. When the amount of graphene oxide is 0.1 wt.%, the comprehensive performance of the composite coating is the best.

Underwater Coatings Sand mill: Grind graphene to the nanometer level.

6. Quality Control Instruments

Thickness Gauge: Measures the thickness of the applied coating to ensure it meets the specified requirements.

Adhesion Tester: Used to evaluate the bonding strength of the coating to the substrate.

Types of coatings and their requirements

Epoxy coatings: Widely used due to their excellent adhesion and corrosion resistance. Requires precise mixing and application techniques.

Polyurethane coatings: Known for their flexibility and UV resistance, but they also require careful surface preparation and application conditions.

Heat-curing coatings: These coatings require specific curing temperatures, so a controlled heating environment is required during application.

?

Protective Coating Application Considerations

Environmental Conditions: Equipment must be able to operate in the varying temperatures and humidity levels typical of the marine environment.

Compliance with Standards: Coatings must comply with industry standards such as NORSOK M-501 to ensure they can withstand extreme underwater conditions134.

Safety Measures: Given the hazardous nature of some coating materials, proper safety equipment and procedures must be in place during their use.
