China Rust Removal System Suppliers - Factory Direct Derusting Machine for Steel Pipes and Tubing
Key Capabilities
Wire Brush Derusting Mechanism
Rotating wire brushes directly rub against the pipe surface, making it ideal for long, continuous workpieces like Casing and Tubing.
Each derusting grinding head assembly includes: arc-shaped wire brushes, spindle box, coupling, motor, guide shaft, buffer springs, and a lifting device. The wire brushes are customized to match different pipe specifications—pipes with similar dimensions can share the same arc-shaped wire brush, enhancing versatility.
High efficiency and strong adaptability to various tubing/casing sizes, and clean the pipe surface.
Dust Collection System
Dust-laden air first enters the cyclone dust collector through the central air inlet, where a portion of the dust is separated using wind force and gravity. The remaining air then flows into the cartridge dust collector’s cabinet. As the air volume suddenly expands, airflow velocity drops sharply—larger dust particles settle into the lower hopper under their own weight. The remaining fine particles are trapped on the outer surface of the filter cartridges via a combination of screening, collision, adhesion, diffusion, and electrostatic effects.
Cleaned air passes through the filter cartridges and is exhausted through the upper cabinet’s outlet via pipes. Over time, accumulated dust on the cartridges increases system resistance. To keep resistance within acceptable limits, a pulse controller triggers electromagnetic pulse valves sequentially, releasing compressed air from the air tank. This air is jetted through nozzles into the center of each corresponding cartridge (primary air), which in turn induces several times more surrounding air (secondary air) to enter the cartridge. This causes the cartridge to expand rapidly; once the reverse pulse impact fades, the cartridge contracts sharply. This expansion-contraction cycle dislodges excess dust from the cartridge surface, which then falls into the hopper and discharge through the ash discharge system—effectively cleaning the cartridges.
This system combines robust derusting capability with efficient dust control, ensuring clean, precise, and high-performance operation for Pipe maintenance.

Frequently Asked Questions (FAQ)
What is the working principle of the derusting machine?
The machine strips away rust via physical friction or impact force using high-speed rotating wire brushes that rub directly against the pipe surface.
What components make up the derusting grinding head assembly?
Each assembly includes arc-shaped wire brushes, a spindle box, a coupling, a motor, a guide shaft, buffer springs, and a lifting device.
How does the dust collection system operate?
Dust-laden air enters a cyclone dust collector where larger particles are separated by wind force and gravity. Fine particles are then trapped by filter cartridges in the cabinet through screening, collision, adhesion, and electrostatic effects.
How are the filter cartridges cleaned during operation?
A pulse controller sequentially triggers electromagnetic pulse valves to release compressed air. This causes the cartridges to rapidly expand and contract, dislodging accumulated dust into a lower hopper.
What pipe specifications are compatible with this equipment?
The machine features strong adaptability and supports universal steel pipe specifications ranging from 60.3mm to 340mm.
What is the total power consumption and noise level of the machine?
The total machine power is 35KW, and the noise level is strictly controlled at ≤65DB for a better working environment.
