NEWASIA joint

AJ520

The AJ520 rigid joint is designed with a diagonal slide method to provide a solid connection. It is easy to join high-pressure pipes.

Grooved joint for High Pressure and STS
Grooved joint Rigid type
Joint material: Spherical graphite cast iron (GCD450)
Gasket Material: EPDM
Bolt/Nut Material: Carbon steel for mechanical structure
Painting: Epoxy powder painting

Category: Grooved Joint

The Model AJ520 is an angle-pad design rigid coupling for general piping applications where rigidity is required including valve connections, mechanical rooms, fire mains and long straight runs. The angle-pad design allows the coupling housings to slide along the bolt pads when tightened. The result is an offset clamping action which provides a rigid joint that resists flexural and torsional loads.

AJ520 couplings should always be installed so that the coupling bolt pads make metal to metal contact
