diaphragm couplings for oil and gas pipelines

Discover the Power of Diaphragm Couplings for Oil and Gas Pipelines


Our top-notch, high-performance diaphragm couplings are specifically designed for oil and gas pipeline applications. These couplings offer a unique blend of design and operational principles that ensure durability, efficiency and maximum performance under various conditions.

Design and Operational Principles

Diaphragm couplings operate through a series of thin, flexible discs or “diaphragms” that allow for transmitting torque while accommodating misalignments. They are designed to tolerate high temperatures, pressures, and corrosive environments common in oil and gas pipelines. The robust design ensures longevity and reliability of the couplings.


Benefits of Diaphragm Couplings

Diaphragm couplings offer numerous benefits including high torsional stiffness, zero backlash, and excellent misalignment capabilities. They are also maintenance-free and provide a reliable and efficient connection in your oil and gas pipeline system.

Selection Criteria

When selecting a diaphragm coupling, consider factors such as torque capacity, operating conditions, misalignment capabilities, and the nature of your application. Always choose a coupling that can withstand the demands of your specific oil and gas pipeline system.

Installation and Maintenance

Our diaphragm couplings are easy to install and require minimal maintenance. Regular inspections can help ensure optimal performance and longevity of the coupling.
