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).

The package should be accompanied by a valid certificate of product conformity, including the product name, product marking, production date, manufacturer name, factory address, trademark and implementation standard number.Ensure that the goods are delivered to the customer completely.
The material of double flange limited expansion joint is mainly Q235 carbon steel, stainless steel, cast steel, ductile iron and so on. Different materials and models are chosen for different purposes.
The factory was established in 1985, integrating design, manufacture, processing and sales. The main product series include: rubber expansion joints, bellows expansion joints and flexible metal hoses. Widely used in petroleum, chemical, metallurgy, power, construction, thermal power, water supply and other industries.
