Extended Repair Sleeve With PTFE Lining For Chemical Pipelines Pressure-sealing Extended Repair Kit Axial Compensation Extended Flexible Pipe Connector
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
