In modern tunnel construction projects, the efficiency and precision of small duct processing directly impact overall project quality and safety. As a professional manufacturer of industrial tunnel equipment, Xuhui (Shandong) Intelligent Equipment Co., Ltd. has developed an advanced small duct punching and shrinking integrated production line that combines cutting, punching, and shrinking processes into one automated system. This innovative solution not only improves production efficiency by 300% compared to traditional methods but also ensures consistent product quality that meets international engineering standards.
Technical Advantages of Our Small Duct Production Line
The integrated production system developed by Xuhui Intelligent incorporates several cutting-edge technologies that set it apart from conventional equipment. First, the system features a high-precision servo punching mechanism capable of achieving hole positioning accuracy within ±0.1mm, which is crucial for maintaining structural integrity in tunnel support systems. Second, the automatic shrinking module uses induction heating technology to ensure uniform temperature distribution during the shrinking process, preventing material deformation and ensuring consistent product quality.
Our production line is designed with modular components that allow for flexible configuration based on specific project requirements. The standard system includes: automatic feeding unit, CNC punching station, induction shrinking module, and finished product collection system. For larger-scale projects, we can integrate additional stations such as marking units, quality inspection systems, and automatic packaging lines to create a complete production ecosystem.
The control system utilizes industrial-grade PLC combined with a touchscreen HMI interface, enabling operators to easily set processing parameters and monitor production status in real-time. The system supports multiple language options and stores up to 100 different processing programs, making it suitable for international projects with diverse requirements. The integrated safety protection system includes emergency stop buttons, photoelectric sensors, and protective covers to ensure operator safety during production.
Application Scenarios in Tunnel Engineering
Xuhui’s small duct production lines have been successfully implemented in numerous tunnel construction projects worldwide, including highway tunnels, railway tunnels, and urban subway systems. In the Xiong’an New Area subway project, our equipment processed over 50,000 meters of small duct per month with a defect rate of less than 0.3%, significantly improving construction efficiency and reducing material waste.
The equipment’s versatility makes it suitable for processing various types of small duct materials, including carbon steel, stainless steel, and alloy steel with diameters ranging from Φ32mm to Φ108mm. In the Chengdu-Chongqing high-speed railway project, our production line efficiently processed both standard and customized small duct specifications, demonstrating its adaptability to complex engineering requirements.
For international projects, our equipment complies with CE standards and can be customized to meet specific country regulations. In the Indonesia Jakarta-Bandung high-speed railway project, we modified the electrical control system to adapt to local voltage standards and provided multilingual operation manuals, ensuring smooth equipment operation and maintenance.

Customization Capabilities for International Projects
Understanding the diverse requirements of global tunnel construction projects, Xuhui Intelligent offers comprehensive customization services for our small duct production lines. Our engineering team works closely with clients to develop tailored solutions that address specific project challenges, including:
- Adaptation to local voltage standards and power supply systems
- Multi-language control interface development
- Special material processing capability enhancement
- Integration with existing production management systems
- Compliance with specific country safety regulations
In the Malaysia East Coast Rail Link project, we customized the production line to process ultra-long small duct sections (up to 12 meters) by adding an automatic feeding extension system and reinforcing the equipment frame structure. This modification enabled the client to reduce welding seams by 60%, significantly improving construction efficiency and structural integrity.
For projects in cold climate regions, we offer optional heating systems for the hydraulic components and lubrication system to ensure reliable operation in temperatures as low as -20°C. This feature was successfully implemented in the Russia Moscow-Kazan high-speed railway project, where our equipment maintained stable performance throughout the harsh winter construction period.
