1. Core Features & Design Innovations
A. Extended Flexibility
Axial Compensation: Up to ±50mm displacement (vs. standard ±15mm),
ideal for seismic zones or subsidence-prone areas (e.g., 30mm
annual ground settlement tolerance in Shanghai metro projects).
Multi-Layer Construction:
Inner Layer: EPDM/FKM/PTFE (chemical resistance).
Reinforcement: Aramid fiber mesh (burst pressure ≥25MPa) or
stainless steel wire (for abrasive media).
Outer Jacket: UV-stabilized CR rubber or armored PVC (mechanical
protection).
COMPANY VIDEO
The pipeline repairer is a device used for pipeline repair,
featuring robustness, corrosion
resistance, and no need for welding.
Product features: connection, robust and corrosion-resistant, no
welding required, no fire
hazard, space-saving, not limited by pipe material,
pressure-sealing, easy installation.
Application: surface/underground engineering, shipbuilding/offshore
oil platforms, water,
gas/natural gas supply, power, industrial production, sewage
treatment, and maintenance etc
