Pipe Conveyor Belt — Fully Enclosed, Clean & Efficient Bulk Handling
Pipe Conveyor Belt: Revolutionary Enclosed Transport System
Transform your material handling with our advanced pipe conveyor belt technology, delivering superior performance through innovative tubular design that ensures efficient, clean, and versatile conveying solutions.
Fully Enclosed Material Transport
Our pipe conveyor belt encapsulates materials within a tubular structure, preventing spillage, dust emission, and contamination during transport. This enclosed design ensures pollution-free operation, protecting both your materials and the environment while maintaining workplace cleanliness and safety standards.
Steep Angle Conveying Capability
The tubular structure increases friction between materials and the belt's inner surface, enabling transport angles typically up to 30° or more. This steep-angle capability significantly reduces space requirements, allows for more compact system layouts, and decreases overall installation costs compared to conventional flat belt systems.
Flexible Spatial Layout Design
The pipe belt's tubular structure enables both vertical and horizontal curves, allowing the system to navigate around obstacles, cross roads, railways, and rivers without intermediate transfer points. This flexibility results in highly economical overall layouts with smaller curve radii, reducing land requirements and infrastructure costs.
Bidirectional Material Transport
Under specific process conditions, the pipe belt's return branch can also transport materials. With high-tensile steel cord core construction and optimized formulation design for process control, we produce high-strength, long-distance, large-diameter steel cord pipe conveyor belts capable of bidirectional operation for maximum operational efficiency.

Confidence through proven performance validation
Request Testing ProtocolsCritical Performance Analysis & Optimization
Understanding that rigidity characteristics directly impact operational resistance, we focus on optimizing belt cross-section geometry to minimize friction while maintaining structural integrity.
Industry emphasis on rigidity alone can be misleading. Lower rigidity doesn't automatically mean lower resistance. The key factor is achieving the optimal pipe cross-section shape.
When the pipe belt approaches a perfect hexagonal cross-section, idler contact transitions from point contact within the hexagon to line contact at the hexagon edges, significantly increasing resistance despite lower rigidity values.
Optimal Belt Performance
Proper structural design and manufacturing processes create belts that maintain near-circular cross-sections under tension. This geometry ensures point contact with idlers, minimizing rolling resistance and maximizing energy efficiency throughout the system's operational life.
Suboptimal Design Consequences
Optimize your system efficiency with properly designed pipe belt geometry
Professional Installation & Commissioning Guidelines
Proper installation and precise alignment are critical for achieving optimal performance and maximum service life from your pipe conveyor belt system. Our expert guidance ensures successful commissioning.
Proper Splice Orientation
The pipe belt splice direction must align with the horizontal transition direction to ensure superior tensile strength and buckling resistance. Standard practice uses horizontal transition and tension force direction as primary considerations for simple routing.
Sequential Belt Installation
When the belt operating direction first touches the side idler, easy belt edge damage occurs. During belt operation, first contact and tension the top and bottom idlers, then contact the side idlers to prevent edge damage and ensure proper belt positioning.
Precise Belt Tracking Adjustment
Identify where the pipe belt begins to deviate from proper alignment, then adjust the tracking idlers from that position. Fine-tune the idler orientation clockwise to gradually force the pipe conveyor to rotate counter-clockwise, correcting the deviation.
Overlap Direction Protocol
Ensure proper overlap direction aligns with material segment expectations for movement direction.

Primary Failure Categories During Operation
- Belt Expansion (Ballooning)
- Belt Blockage (Plugging)
- Belt Twisting (Spiraling)
- Belt Edge Damage (Abrasion)
Belt Expansion Issues
Root Cause:
Structural design problems where the pipe belt cannot maintain proper tubular shape. Poor structural design creates excessive flexibility, causing the belt to deform into a hexagonal shape that makes contact with idlers through face contact rather than the intended tangential point contact within the hexagon.
Belt Blockage Problems
Primary Causes:
• Insufficient structural rigidity in belt design
• Unreasonable pipe conveyor parameters (excessively small pulley diameter, inadequate transition length)
• Excessive edge tension exceeding 115% of nominal belt tension (International Standard) or 130% (MT/T 645-1997)
• Center tension below 0 N/mm creating free slack
Consequences:
Transition section distance deficiencies lead to improper guidance, causing belt buckling failure. Reduces service life of joints and adhesion, ultimately causing system failure and costly downtime.
Belt Twisting Failures
Contributing Factors:
• Unreasonable structural design with poor stability - hexagonal rigidity distribution imbalance
• Improper pipe conveyor working parameters - misaligned idler group spacing causing asymmetric forces
• External environmental factors causing sudden resistance changes due to belt edge tearing, rainwater infiltration, or similar conditions
Belt Edge Damage
Mechanism:
At constant speed operation through convergence and expansion transition sections, the belt requires external force from idlers to close into tubular form at convergence. During expansion transition, idlers must apply external force to open the tube. These transition zones create high shear friction forces between idlers and belt edges, causing accelerated wear to both the belt edge and idler surfaces.
Comprehensive Prevention Strategies
Edge damage of pipe belts is a common system-wide issue. Current improvement methods focus on three key areas:
- Optimize structural design to minimize edge rigidity while maintaining overall belt strength
- Refine production processes, including forming belt edges with rounded arc profiles instead of standard corners
- Improve transition section layout and optimize idler structural design for reduced edge stress
