In modern tunnel construction projects, the efficiency and precision of small duct processing directly impact overall project quality and progress. Xuhui (Shandong) Intelligent Equipment Co., Ltd., located in Heze – China’s well-known engineering machinery manufacturing base, has become a leading supplier of fully automatic tunnel small duct production lines through continuous technological innovation and quality improvement. Our equipment integrates cutting, hole punching, and tip forming functions, providing complete solutions for tunnel support system construction.
Technical Advantages of Xuhui’s Tunnel Small Duct Production Line
Our fully automatic production line represents the latest achievements in tunnel construction equipment technology, featuring several key advantages that set it apart from traditional processing methods. First, the equipment adopts high-precision servo control system with positioning accuracy reaching ±0.1mm, ensuring consistent quality across all processed ducts. The integrated design combines cutting, hole punching, and tip forming processes, reducing material handling times by 60% compared to separate operations.
The production line’s modular design allows flexible configuration based on different project requirements. Standard models can process ducts from φ32mm to φ108mm in diameter, with length adjustment range of 0.5-12 meters. For special projects, we offer custom solutions that can extend processing capabilities to φ159mm ducts and longer lengths. The automatic lubrication system ensures stable operation during continuous production, with maintenance intervals extended to 2000 working hours.
Energy efficiency is another significant advantage. Compared to traditional equipment, our production line reduces power consumption by 35% through optimized motor selection and intelligent power management. The dust collection system meets EU CE standards, effectively controlling workshop dust concentration below 8mg/m³. These features not only improve working conditions but also help construction companies meet environmental protection requirements in different countries.
Core Components and Processing Capabilities
The fully automatic tunnel small duct production line consists of several key modules: automatic feeding system, high-speed cutting unit, precision hole punching station, tip forming device, and intelligent control system. Each component is designed for maximum reliability and processing precision. The feeding system uses servo-driven roller conveyors that can handle coils up to 3 tons without deformation. The cutting unit adopts plasma cutting technology with automatic arc voltage control, ensuring clean cuts without burrs.
The hole punching station features a multi-position turret design with 12 tool positions, allowing quick changeover between different hole patterns. The CNC control system can store up to 200 processing programs, supporting complex hole distributions required by various tunnel designs. Tip forming is achieved through a combination of hydraulic pressing and precision grinding, producing consistent conical tips with angle accuracy of ±0.5°. The entire processing cycle for a standard 6-meter duct takes less than 8 minutes, including material loading and unloading.
To help clients better understand our equipment’s capabilities, here’s a comparison of key parameters between our standard model and industry average:
| Parameter | Xuhui Standard Model | Industry Average |
|---|---|---|
| Positioning Accuracy | ±0.1mm | ±0.3mm |
| Processing Cycle | 8 minutes/6m duct | 15 minutes/6m duct |
| Power Consumption | 18kW/h | 28kW/h |
| Noise Level | ≤75dB | ≤85dB |
Global Application Cases
Our tunnel small duct production lines have been successfully applied in major infrastructure projects across 30 countries and regions. In Southeast Asia, a highway tunnel project in Malaysia adopted our equipment to process over 50,000 meters of small ducts monthly. The automated production reduced labor costs by 70% while improving product consistency. In the Middle East, a metro construction project in Dubai used our custom solution to process φ159mm large-diameter ducts, meeting the project’s special technical requirements.
European clients particularly appreciate our equipment’s compliance with CE standards. A railway tunnel project in Italy reported that our production line’s dust collection system helped them meet strict local environmental regulations, avoiding potential fines and project delays. In Africa, our equipment’s robust design and simple operation proved ideal for local conditions, enabling smooth operation even in areas with unstable power supply.

FAQ
What makes Xuhui’s tunnel small duct production line different from other suppliers?
Our equipment features three unique advantages: First, the integrated design combines cutting, hole punching, and tip forming in one line, improving efficiency by 40% compared to separate machines. Second, we use German-imported servo motors and precision ball screws, ensuring positioning accuracy of ±0.1mm. Third, our equipment has passed EU CE certification and meets international safety standards, making it suitable for global projects.
How long does it take to train operators for this equipment?
We provide comprehensive training programs that typically take 3-5 days. The training includes theoretical courses on equipment structure and working principles, practical operation exercises, and basic maintenance skills. After training, operators can independently handle normal production operations and simple troubleshooting. For international clients, we offer multilingual training materials and online support.
What is the warranty period and what does it cover?
Our standard warranty is 12 months from equipment acceptance or 2000 working hours, whichever comes first. The warranty covers all mechanical and electrical components excluding consumables like cutting nozzles and punching dies. During the warranty period, we provide free replacement of defective parts and on-site repair services for major failures. We also offer extended warranty packages up to 3 years for clients with special requirements.
Can the equipment be customized for special project requirements?
Yes, customization is one of our core strengths.
