Overview of Steel Pipe Shot Blasting Machine

Definition: A steel pipe shot blasting machine is a specialized surface cleaning device that uses high-speed projected steel shots or abrasives to clean, derust, descale, or strengthen the inner and outer surfaces of steel pipes.

Core Working Principle
1. Shot Blasting System:
- A high-speed rotating impeller (shot blasting wheel) accelerates steel shots to 60-100 m/s, impacting the pipe surface to remove rust layers, welding slag, and other impurities.
2. Circulation System:
- Steel shots are separated from impurities via recovery devices (screw conveyor, elevator) and recycled for reuse.
3. Dust Removal System:
- Equipped with cartridge or baghouse dust collectors to reduce dust pollution, meeting environmental requirements.

Main Types
1. Roller Conveyor Shot Blasting Machine
- Pipes are conveyed through the blasting chamber via rollers, suitable for continuous processing of large batches and long pipes.
2. Hanger-Type Shot Blasting Machine
- Pipes are suspended on hooks and rotated, ideal for multi-angle cleaning of short pipes or irregular fittings.
3. Through-Feed Steel Pipe Shot Blasting Machine
- Pipes pass through the blasting zone individually or in groups, commonly used for pipe pretreatment (e.g., before coating).

Typical Application Scenarios
- Oil/Gas Pipelines: Remove weld oxide layers to improve anti-corrosion coating adhesion.
- Building Steel Structures: Eliminate rust on pipe surfaces to extend service life.
- Automotive Manufacturing: Surface strengthening of components like drive shafts and exhaust pipes.
- Marine Engineering: Anti-rust treatment of large pipes.

Equipment Advantages
- High Efficiency: Processing speed of 1-30 meters per minute (depending on model).
- Quality Improvement: Achieves Sa2.5-Sa3 cleanliness levels (ISO 8501 standard) on pipe surfaces.
- Eco-Friendly & Energy-Saving: Steel shot recycling rate >95%, combined with dust removal systems to reduce pollution.
- High Automation: Can integrate PLC control for automatic feeding, blasting, and sorting.

Key Purchasing Parameters
1. Pipe Specifications: Diameter range (e.g., Φ20mm-Φ2000mm), length (typically ≤12m).
2. Processing Capacity: Hourly throughput (e.g., 5-50 tons).
3. Number of Blasting Wheels: 2-8 units, affecting cleaning efficiency.
4. Power Requirements: Main motor power typically 15-200kW.

Maintenance & Safety
- Daily Maintenance:
- Regularly inspect wear parts of the blasting wheel (blades, impeller).
- Clean separator screens to ensure steel shot purity.
- Lubricate bearings, chains, and other moving parts.
- Safe Operation:
- Do not open inspection doors while the equipment is running.
- Wear protective gear such as dust masks and safety goggles.

--- Cost Reference
- Small Equipment: Approximately 100,000-300,000 RMB.
- Large Automated Production Lines: 1,000,000-5,000,000 RMB.
