Quick couplings for up to 100 bar

One advantage with the Alvenius steel pipe system is the easy installation due to the quick-coupling system. No welding, no special tools, no time-consuming training plus entirely without hot work.

CG/RG & AGS

Alvenius CG/RG is a quick coupling system with ISO standard for pressure up to 80 bar. Alvenius AGS is for larger sizes with pressure up to 25 bar.

The coupling is available as flexible and rigid. Flexible means that the coupling allows some deflection and takes up vibrations or temperature fluctuations. Rigid means that the
coupling is completely rigid and equivalent to a welded joint.

Special couplings are available for even higher pressures.

CG/RG & AGS

  • Dimensions - CG/RG Ø60–323 mm, AGS Ø355-610 mm
    Rigid or flexible couplings
    Wide selection of rubber gaskets depending on application and media to be transported in the pipe
    Self-tightening gasket. Also works under certain circumstances for vacuum
    Up to 2.5° angular deflection depending on dimension
    Insensitive to vibration
    Can handle axial movement, for example due to thermal expansion

Alvenius K10/K70

Alvenius K10/K70

Alvenius K10 is a quick coupling system with a "shoulder" at each end of the pipe. The system is available in standard metric sizes for pressures up to 40 bar, depending on size.
K10 is a flexible system and each coupling can handle angles of up to 4°.

K70 is a hinged coupling for even faster and more flexible assembly – only a single bolt needs to be tightened.

  • Dimensions Ø48–318 mm.
    Self-tightening gasket. Works also for vacuum under certain circumstances
    Standard gasket of EPDM rubber, also resistant to chemicals
    Working temperature -35 to + 110°
    Nitrile or silicon gasket for prolonged contact with petroleum
    Up to 4°angular deflection
    Insensitive to vibration
    Absorbs axial movement in the pipe system due to axial play in the coupling
