Concentric reducing expansion joints: The flexible solution for diameter transitions in industrial piping.

BIKAR Expasion Joints has supplied a batch of concentric reducing rubber expansion joints for an industrial installation that required an efficient transition between different pipe diameters. These joints are designed to absorb movements while maintaining the safety and efficiency of the system.

Thanks to their concentric reducing design, with inlet and outlet flanges aligned, this type of joint enables a smooth flow transition, preventing issues such as turbulence, pressure loss, and unwanted vibrations.

Why choose concentric reducing expansion joints?

Efficient diameter transition – Their design allows a smooth transition between different pipe diameters, optimizing the hydraulic performance of the system.
High movement absorption – The design provides flexibility and the ability to absorb axial and lateral movements, reducing stress on the installation.
Custom engineering solutions – Each joint is manufactured according to project requirements, adapting materials, geometries, and specific configurations.

Key characteristics and properties:

Manual manufacturing.
Dimensions up to DN 4000 (160”).
Integrated one-piece vulcanized flanges.
Specific design based on requirements.
Optional PTFE inner lining.
Low tightening torque.
Available in Neoprene, EPDM, Food Grade EPDM, Hypalon, Nitrile, FKM-Viton, Peroxidized EPDM, silicone, among others.

 

 

Technical specifications of this project:

Type: Concentric reducing rubber expansion joints
Diameter range: DN 500 to DN 300
Body material: EPDM
Accessories: Tie rods

The incorporation of control rods allows the limitation of movements and control of the forces generated within the system, increasing safety and extending the service life of the installation.

Bikar Expansion Joints is one of the leading companies in custom-designed expansion joints, meeting the increasingly demanding requirements of industrial projects worldwide.
