The applications of shot blasting machines in the field of shipbuilding are extensive and significant, and are specifically manifested in the following aspects:

Ship plate surface treatment:

Remove rust, oxide scale and marine attachments from the surface of ship plates. For instance, before processing the ship plates of newly built ships, shot blasting machines can quickly and effectively clean their surfaces, providing a good foundation for the subsequent welding and coating processes.

Increase the roughness of the ship plate surface to enhance the adhesion of the coating and strengthen the rust prevention and anti-corrosion ability of the ship.

Ship structural component treatment:

Conduct rust removal and strengthening treatment on structural components such as steel beams and frames of ships to prolong their service life. For example, during the modification and maintenance of ships, shot blasting machines can restore the surface performance of structural components.

Improve the distribution of residual stress on the surface of structural components to enhance their fatigue strength and ensure the safety of ships during navigation.

Propeller and rudder blade treatment:

Clean the dirt and corrosion products on the surface of propellers and rudder blades to optimize their hydrodynamic performance and improve the propulsion efficiency and maneuverability of ships.

Interior of the cabin treatment:

Clean and pre-treat the steel structures inside the cabin to prepare for coating with fireproof and anti-corrosion coatings.

Pipeline and valve treatment:

Remove rust and impurities from the surface of pipelines and valves to ensure their normal operation and sealing performance in the ship's system.

Refurbishment of second-hand ships:

For the renovation and refurbishment of second-hand ships, shot blasting machines can completely remove old coatings and rust, making the ships look brand new and restoring their performance and appearance.

In conclusion, the application of shot blasting machines in the field of shipbuilding plays a non-negligible role in improving the quality, durability and safety of ships.
