Double Flanged Connections What does “Double Flanged Connections” Mean?

Restrained What does “Restrained” Mean?

They transfer the longitudinal forces pipe to flanged connection.
They can be used to negate the need of concrete thrust blocks and pipe bends etc.
They can accommodate angularity at installation but no angular rotation in service.

Mechanical engagement with pipe prevents pull out under pressure

Flexible What does “Flexible” Mean?

They allow for expansion and contraction and ground movement in a pipeline.
They DO NOT transfer the longitudinal forces from one pipe to the other in the connection.
Adequate external restrain has to be provided to prevent pipes from pulling out of the coupling.

Gasket provides sealing only Without an end load restraint, pipe may be displaced under internal pressure

Restrained What does “Restrained” Mean?

They transfer the longitudinal forces from one pipe to the other in the connection.
They can be used to negate the need of concrete thrust blocks and pipe bends etc.
They can accommodate angularity at installation but no angular rotation in service.

Physical engagement with pipes preventing them pulling gout under pressure.

They allow for expansion and contraction and ground movement in a pipeline.
They DO NOT transfer the longitudinal forces from one pipe to the other in the connection.
Adequate external restraint has to be provided to prevent pipes from pulling out of the coupling.

Gaskets simply seal on pipes meaning they can pull out under pressure

They transfer the longitudinal forces pipe to flanged connection.
They can be used to negate the need of concrete thrust blocks and pipe bends etc.
They can accommodate angularity at installation but no angular rotation in service.

Gasket simply seals on the pipe, so it can pull out under pressure

Pipe jointing is the process of connecting sections of pipe to create a secure, leak-tight system. Viking Johnson offers a range of mechanical fittings designed for a wide variety of pipe materials and applications.

Joining pipes of different diameter Joining pipes equal diameter

Joint Type:

Regrettably Viking Johnson does not have a product range that is compatible with your pipe selection; contact our technical support team for further guidance.

The pipe materials selected require different product ranges and hence it is not possible to offer a coupling / reducing coupling solution. Back to Back flange adaptors may offer a solution.

Regrettably Viking Johnson does not have a product range that is compatible with your selection; contact our technical support team for further guidance.

A flange connection is used to join a plain-ended pipe to a flanged valve, fitting, or equipment within a water network. It provides a secure, reliable connection that supports installation, maintenance, and system operation.

A double flanged fitting that accommodates end load forces and longitudinal adjustment between to join two flanged components within a water network. Dismantling Joints provide easier installation and dismantling to facilitate the removal of pipeline equipment during maintenance.

Provide longitudinal adjustment between flanges

Under pressure tapping fittings enable branch connections in a live pipeline without interrupting water supply. EasiRange & HandiRange provide a reliable solution for creating branch connections quickly and efficiently while the pipeline remains under pressure.

End terminations are used to safely seal the end of a pipeline or isolate future network connections. Viking Johnson solutions provide a secure, reliable seal while allowing flexibility for further system modifications.

Wall Couplings fit flush between formwork panels to provide a cost-effective means of passing a pipework through a concrete wall or slab. Viking Johnson Wall Couplings provide a secure seal, come with various end configurations to accommodate site conditions and reduce damage to formwork panels.

Flow stopping equipment is used to isolate a section of pipeline, allowing maintenance & repairs to be carried out without shutting down the entire network. WASK AquaStop & Hydrant Wizard help minimise disruption by maintaining service continuity during critical works.

PVC is a generic term for various types / brands of pipe (e.g. PVC-U, PVC-O, HEP30, MOPVC etc.) and the actual grade will influence the selection Viking Johnson fitting. Please review details provided for each product to ensure they work on the grade being used.

Due to the surface finish of stainless steel pipe not being suitable for the gripping systems in Viking Johnson restrained products the only fitting we can offer is a flexible one with external restraining methods as necessary.

The use of flexible fittings are not recommended on Polyethylene (PE), Polypropylene & PE Barrier pipe; for further guidance consult knowledge hub section.

If the damage to the pipe is too severe to require a cut out and replace a section of pipe please refer to “Pipe Jointing” for further guidance.

End termination on PE barrier pipe can be done using an AquaShield flange adaptor with a blank flange.
