Project Background
In modern subway and rail transit construction projects, large volumes of pipe processing are required for infrastructure systems, including ventilation ducts, fire protection pipelines, station support structures, cable protection systems, and other engineering components.
These applications involve a wide range of pipe specifications and materials such as carbon steel, stainless steel, and galvanized steel. The processing accuracy and consistency directly impact installation efficiency and long-term system stability.
D Rail Transit Group required a high-efficiency pipe cutting solution to support batch production and complex structural requirements in subway engineering environments.
The Challenge
During rail transit fabrication, the customer faced several production challenges:
Processing multiple pipe types including round, square, and rectangular profiles
Ensuring high precision cutting for complex structural connections
Supporting large-scale batch production for subway infrastructure projects
Maintaining consistency across long production cycles
Reducing manual handling and secondary processing work
Traditional mechanical cutting methods and semi-automatic processing systems often result in lower efficiency, inconsistent precision, and higher labor dependency.
QLTEK Solution
To meet these requirements, QLTEK provided the P3 PRO High-Speed Tube Laser Cutting Machine.
This system is specifically designed for high-precision and high-efficiency pipe processing in industrial applications such as rail transit engineering.
The machine supports automatic feeding and continuous cutting of multiple pipe profiles, including:
Round pipes
Square pipes
Rectangular tubes
Custom structural profiles
It enables stable, automated batch processing while maintaining cutting accuracy and production efficiency.
Traditional Process vs Laser Tube Cutting
Compared with conventional pipe cutting methods such as sawing, drilling, and plasma cutting, high-speed fiber laser tube cutting offers significant advantages:
Higher cutting precision for complex pipe intersections
Reduced deformation during processing
Eliminates secondary finishing and grinding work
Improved consistency in batch production
Faster overall production flow for large-scale engineering projects
This makes it particularly suitable for rail transit manufacturing environments where precision and efficiency are both critical.
