Steel plate shot blasting machines are vital across industries that rely on clean, structurally sound metal surfaces. Below are their key uses:  

1. Construction and Structural Steel Fabrication

Bridge and Building Components:  

  Cleans and prepares steel plates for beams, columns, and trusses by removing mill scale and rust, ensuring proper weldability and paint adhesion.  

  Example: In a skyscraper project, shot blasting ensures structural plates meet ASTM A6 standards for surface cleanliness, reducing the risk of corrosion in high-rise frameworks.  

Storage Tanks and Silos:  

  Prepares plates for welding into storage tanks (e.g., oil, water, or grain silos) by eliminating contaminants that could compromise structural integrity or cause leaks.  

  Surface roughness (50–75 microns) enhances the bond of protective coatings like epoxy or zinc-rich primers, critical for resisting environmental exposure.  

2. Shipbuilding and Marine Engineering

Hull and Deck Plates:  

  Removes saltwater corrosion, marine growth, and old paint from ship plates, meeting ISO 8501-1 Sa2.5 standards for anti-fouling coatings.  

  Shot blasting with steel grit ensures rough surfaces that prevent paint peeling in harsh marine environments, where re-coating can cost millions of dollars per vessel.  

Offshore Platforms:  

  Treats steel plates for offshore structures like oil rigs and wind farms, combating corrosion from salt spray and high humidity.  

  Internal blasting attachments may clean hollow sections or pipe interiors, ensuring all surfaces are protected.  

3. Automotive and Heavy Machinery Manufacturing

Chassis and Frame Components:  

  Prepares steel plates for vehicle chassis by removing冲压 (stamping) oils and scale, improving the durability of powder coatings or electroplating.  

  Shot peening with steel shot enhances fatigue resistance in high-stress components like truck frames, reducing the risk of cracks during operation.  

Agricultural Equipment:  

  Cleans plates for tractors, harvesters, and machinery housings, ensuring resistance to dirt, moisture, and chemical fertilizers.  

  A tractor manufacturer might use shot blasting to prepare plates for cab bodies, increasing paint longevity in dusty farm environments.  

4. Oil and Gas Industry

Pipeline and Storage Infrastructure:  

  Treats steel plates for pipe fabrication (e.g., longitudinal or spiral welded pipes) by removing rust and mill scale, ensuring compliance with API standards.  

  For subsea pipelines, shot blasting achieves Sa3 (white metal) cleanliness, essential for applying fusion-bonded epoxy (FBE) coatings that prevent corrosion in deep-sea environments.  

Refinery Components:  

  Cleans plates for pressure vessels, heat exchangers, and other refinery equipment, removing contaminants that could interfere with welding or cause chemical corrosion.  

5. Metal Recycling and Demolition

Salvage and Reclamation:  

  Restores used steel plates from demolition sites by removing paint, rust, and concrete residues, making them suitable for reuse in non-critical applications (e.g., temporary barriers, agricultural structures).  

  A recycling plant might process 500 tons of steel plates monthly, using shot blasting to remove up to 95% of surface contaminants, reducing smelting costs.  

Scrap Metal Processing:  

  Prepares plates for recycling by stripping them of non-metallic materials, improving the purity of recycled steel and reducing environmental impact.  

6. Aerospace and Defense

Aircraft Components:  

  Uses fine ceramic beads or glass media to blast aluminum or titanium plates without damaging delicate surfaces, preparing them for anodizing or bonding.  

  Shot peening is critical for aerospace components like wing spars, enhancing fatigue life by introducing compressive surface stresses.
