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.
This mechanism guarantees high efficiency and strong adaptability to various tubing/casing sizes, ensuring a thoroughly clean 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)
Q: What is the working principle of the derusting machine?
Rust is stripped away from the pipe surface via physical friction or impact force using high-speed rotating wire brushes.
Q: Which types of pipes is the wire brush mechanism suitable for?
It is highly ideal for long, continuous workpieces such as Casing and Tubing, and can easily adapt to various tubing/casing sizes.
Q: How does the dust collection system operate initially?
Dust-laden air first enters a cyclone dust collector where larger dust particles are separated using wind force and gravity, before the remaining fine particles move to the filter cartridges.
Q: How are the filter cartridges cleaned during operation?
A pulse controller triggers electromagnetic pulse valves to release compressed air. This creates a rapid expansion-contraction cycle in the cartridges, dislodging the excess dust into the hopper.
Q: What is the total power requirement and noise level of the machine?
The total machine power is 35KW, and the equipment operates at a controlled noise level of ≤65DB.
Q: Is the system environmentally friendly?
Yes, the system is designed with a strict emission concentration of ≤20mg/m³, ensuring clean and eco-friendly operation for pipe maintenance.
