Application of Double Wall Corrugated Pipe
Core Advantages
Fixed Center Height Technology — No adjustment required for spec changes, single-screw mold changeover
Double Gear Independent Track Drive — Synchronized force distribution for smoother module operation
Dedicated Tractor System — Signal directly from cutter ensures precise cutting synchronization
Closed-Loop Pressure Water Cooling — Fully sealed cooling eliminates leakage and rust
Intelligent Stacker Weighing System — Real-time single-pipe weighing for meter-weight monitoring
Five Major Technical Innovations:
1. Fixed Center Height Design
The fixed center height architecture eliminates the need for any height adjustment when changing pipe diameter specifications. Only one screw needs to be loosened to complete the specification switch, making operation extremely convenient. All module widths, installation dimensions, and operating methods are fully standardized, achieving 100% universal module interchangeability.
Customer Value:
· Significantly reduces equipment investment and maintenance costs
· Flexible production organization with rapid response to order changes
· Reduced downtime, improved Overall Equipment Effectiveness (OEE)
2. Double Gear Drive + Independent Running Track
Upgrading from traditional single-gear drive to a double-gear drive system ensures simultaneous force application on both upper and lower sides of the sliding seat, effectively eliminating uneven force distribution during operation for more stable and reliable module movement. The upper and lower tracks operate independently, ensuring long-term stable operation under any working conditions.
Customer Value:
· Eliminates off-center loading, extending rail and module lifespan
· Maintains excellent stability even at high-speed operation
· Reduces vibration and noise, improving workshop environment
3. Dedicated Tractor System
The tractor signal originates directly from the cutting machine, ensuring synchronization and precision at the pipe cutting moment, significantly reducing miscutting rates. The tractor also provides additional forward thrust for the pipe, effectively reducing the molding machine load and preventing over-current shutdown protection triggers.
Customer Value:
· Improved cutting precision with reduced scrap rate
· Prevents pipe accumulation and expansion deformation
· Protects the molding machine, reducing unplanned downtime
4. Closed-Loop Pressure Water Cooling System
Modules feature fully sealed pressure water cooling design, completely eliminating cooling water leakage and equipment rust issues, significantly extending equipment service life. The cooling water circulation system has been upgraded from single-row roller chain to double-row roller chain, making pipeline circulation more stable and preventing socket tilting.
Customer Value:
· Zero-leakage design with minimal maintenance costs
· Enhanced cooling efficiency for higher production capacity
· Stable socket quality, improved product pass rate
5. Intelligent Stacker Weighing System
During production, each pipe is weighed in real-time online, continuously monitoring the pipe meter-weight indicator to ensure product quality consistency. Data is fully traceable, facilitating quality management and process optimization.
Customer Value:
· Real-time quality monitoring with immediate anomaly detection
· Data-driven process optimization
· Meets high-end customer quality traceability requirements
