Coupling

 

Coupling

AKA Industrial Group, as the first and only manufacturer of couplings in Iran and the Middle East, produces all kinds of epoxy-coated couplings for pipes of different materials and various outer diameters from 350 mm up to 3000 mm. Couplings are used for joining pipes of the same or different materials with the same outer diameter. Stepped Couplings are used to connect pipes with different outer diameters and pipes of different materials.

Main Advantages of Using AKA Couplings

The most important feature of AKA couplings is the ease and speed in piping operations that effectively decreases project costs by reducing project duration. Besides fast assembling, an AKA Coupling, when used throughout a pipeline, will easily take care of expansion and contraction, limited ground movement and long radius curves.

Sealing Ring

Exclusive AKA sealing rings molded in AKA’s plant meet the exact specifications and assure perfect lifetime sealing while fulfilling all the relevant British standards.
