Shot Blasting Systems for Surface Preparation and Corrosion Protection
13 June 2025
Impact Machinery offers advanced shot blasting systems for efficient surface preparation and corrosion protection across various industrial applications.
Surface preparation is a fundamental step in ensuring the durability and performance of coatings across numerous industrial sectors. Historically, methods such as manual scraping, sanding, and chemical treatments were widely used, but these approaches often lacked efficiency and consistency. Amid rising demands for precision and productivity, shot blasting systems have become a leading solution, enhancing surface adhesion and preventing corrosion in steel structures, pipelines, and heavy machinery.
How Shot Blasting Works
Shot blasting is a mechanical process that propels abrasive material at high velocity against a surface to remove contaminants, roughen the substrate, or polish the material. The system typically utilises centrifugal force generated by a rotating wheel or compressed air to propel steel shots or grit. As the abrasive media strikes the surface, it effectively cleans it by dislodging rust, scale, old paint, or other unwanted residues.
The process is enclosed within a chamber or machine, which collects and recycles the abrasive material for repeated use. This not only ensures a consistent finish but also reduces environmental waste, making shot blasting a more sustainable alternative to chemical or manual cleaning methods.
Applications of Shot Blasting in Surface Preparation
Shot blasting systems have wide-ranging applications across various sectors due to their ability to deliver uniform and reliable results. Below are some of the most common industrial uses:
1. Cleaning and Deburring – Shot blasting removes dirt, grease, and rust from metal surfaces, ensuring a clean, reactive base for optimal coating adhesion.
2. Surface Profiling – Shot blasting creates the ideal surface texture, helping corrosion-resistant coatings bond effectively and last in harsh conditions.
3. Weld Preparation and Inspection – In fabrication and shipbuilding, shot blasting reveals weld defects for thorough inspection before assembly or coating.
4. Structural Maintenance and Restoration – Shot blasting removes old coatings and corrosion in infrastructure like bridges and plants, preparing surfaces for recoating and long-term protection.
Best Practices for Effective Shot Blasting
To achieve the desired results and maintain operational safety, it is essential to adhere to established best practices when using shot blasting systems. These include:
• Surface Preparation Guidelines – Following internationally recognised standards like ISO, SSPC and NACE Standards ensures that surfaces are treated consistently and are adequately prepared for subsequent processes.
• Safety Precautions and Equipment Maintenance – Operators must be equipped with appropriate personal protective equipment, and machines should undergo regular inspection and maintenance to prevent malfunctions and ensure workplace safety.
• Common Mistakes to Avoid During Shot Blasting – Avoid improper abrasive selection, inadequate surface coverage, and over blasting, as these can lead to poor surface quality, increased costs, and equipment damage.
By implementing these practices, businesses can maximise the efficiency and effectiveness of their surface preparation operations.
