With outstanding ring stiffness, corrosion resistance, and construction convenience, these products are gradually replacing traditional steel pipes and concrete pipes, becoming the preferred solution for urban utility tunnels, municipal drainage, industrial wastewater discharge, and other applications.
Multi-Layer Composite Spiral Winding Structure
• Double-Wall Corrugated Spiral Pipe: Corrugated inner and outer walls provide lightweight construction with high ring stiffness (SN8-SN16).
• Double-Wall Spiral Pipe: Smooth inner wall + reinforced outer wall, ideal for high-flow drainage systems.
• Triple-Wall Spiral Pipe: Multi-layer composite structure with ring stiffness exceeding SN16, suitable for deep burial and high-pressure applications.
Intelligent Production System
• PLC Fully Automatic Control: Integrated control system automates extrusion, winding, and cutting processes.
• Composite Die Technology: Modular die design enables quick switching between pipes of different wall thicknesses and structures.
• Online Quality Monitoring: Laser diameter measurement + ultrasonic wall thickness detection for real-time process adjustment.
High-Performance Material Applications
• HDPE Spiral Winding Pipe: Impact-resistant, chemically inert, and service life exceeding 50 years.
• FR-PP Spiral Winding Pipe: Fiberglass-reinforced for 30% higher ring stiffness, suitable for high-load environments.
