What is Internal Steel Tube Shot Blasting Machine? 

An Internal Steel Tube Shot Blasting Machine is a specialized industrial equipment used for surface treatment of the inner walls of steel tubes. It is designed to remove impurities such as oxide layers, welding slag, and rust from the interior surfaces of steel tubes, thereby enhancing their appearance and improving their corrosion resistance. The machine also helps to increase the bonding strength of steel surfaces with coatings and extends the service life of the steel tubes.

Main Components

1. Blast Cabinet: The main enclosure where the blasting process takes place.

2. Blast Wheel Units: These are responsible for propelling the abrasive media (such as steel shot or grit) at high speed onto the inner surface of the steel tube.

3. Abrasive Circulation Unit: Manages the recycling and distribution of the abrasive media.

4. Bucket Elevator Unit: Transports the used abrasive media back to the blast wheel units for reuse.

5. Abrasive Separation/Cleaning System: Separates worn-out abrasive particles and debris from the usable media.

6. Dust Collector: Captures and filters dust generated during the blasting process to reduce environmental pollution.

7. Conveyor System: Transports the steel tubes through the machine, typically using rollers or special handling systems.

8. Control Panel: Equipped with a PLC (Programmable Logic Controller) system to automate and control the entire process.

Working Principle

The machine works by propelling abrasive media at high speed onto the inner surface of the steel tube. The abrasive particles impact the surface, removing rust, scale, and other impurities. The used abrasive media is then collected, separated from debris, and recycled back into the system. This process not only cleans the surface but also reduces internal surface stress, enhancing the tube's durability.

Applications

Internal Steel Tube Shot Blasting Machines are widely used in various industries, including:

1. Petroleum and Chemical Industries: For cleaning and preparing steel tubes used in pipelines and chemical processing equipment.

2. Steel Manufacturing: To improve the surface quality of steel tubes before further processing or coating.

3. Construction and Infrastructure: For treating steel tubes used in building structures, bridges, and other applications.

Advantages

1. High Efficiency: Significantly reduces cleaning time compared to manual methods.

2. Improved Surface Quality: Provides a clean, uniform surface that enhances the adhesion of coatings.

3. Extended Service Life: Reduces internal corrosion and stress, thereby increasing the lifespan of the steel tubes.

4. Environmental Protection: The enclosed system minimizes dust and debris release into the environment.

Customization

These machines can be customized based on the diameter and length of the steel tubes to be processed, as well as specific production requirements.
