The double flange limited expansion joint is composed of main parts, sealing rings, gland, telescopic short pipe and other
main components. On the basis of the original performance of the loose sleeve expansion joint, a limit device is added,
and a double nut is used for locking at the maximum expansion. Pipeline can be free to expand in the allowable expansion,
once exceeding its maximum expansion limit, to ensure the safe operation of the pipeline, especially for vibration or a certain
degree of inclination and bending in the pipeline connection.
Core Functional Roles
1. Displacement Compensation and Stress Elimination
Thermal Compensation: Absorbs axial displacement caused by temperature changes (-30℃ to 350℃)
in pipes (up to ±100mm according to the 2025 EJMA IV standard), preventing leakage at flange sealing
surfaces.
Vibration Buffering: Mitigates mechanical vibrations transmitted from pumps, compressors, and other
equipment (requiring vibration damping efficiency ≥90% in nuclear power fields), protecting sensitive
equipment.
Installation Alignment Correction: The spherical seal design allows for ±5° angular deflection, compensating
for alignment errors during pipe construction (such as misalignment caused by subsidence in underground conduits).
