KLAMFLEX DEDICATEDCOUPLINGS

KLAMFLEX Dedicated Couplings join pipes of the same outside diameter. Couplings up to 324mm OD are delivered pre-assembled. Larger sizes are delivered ready for site assembly on the pipe.

KLAMFLEX Couplings can be manufactured to suit both metric and imperial dimensions for Steel, uPVC, Ductile Iron, G.R.P., Fibre Cement, Stainless Steel, Aluminium Alloys and virtually all other rigid pipe materials.

Klamflex Couplings can be manufactured with double sleeves to prevent end pull out on HDPE and GRP pipes.

The sizes shown in the schedules of dimensions are for guide purposes. KLAMFLEX’S manufacturing methods enable us to supply any size, including non-standard sizes.

KLAMFLEX Couplings are pressure rated to the appropriate pipe standards. Working pressure is generally two-thirds of maximum test pressure shown in the schedules of dimensions. These pressures apply to a buried line with adequate thrust blocks or to pipelines above ground anchored at ends and at all changes of direction also secured against side thrusts at each joint.

KLAMFLEX Couplings, though capable of accommodating reasonable expansion and contrac-tion, do not mechanically prevent separation of pipe ends subject to end thrust, and this must be prevented by other means. To prevent separation of pipe ends, harness assemblies consisting of lugs for welding to adjacent pipes, and connecting tie rods can be supplied. Pipes must be anchored against end load, particularly when the pipeline is laid above ground. A buried pipeline normally needs anchoring only at abrupt changes in direction and at junctions or stop ends.

Gaskets are of a EPDM rubber and are suitable for water and sewerage services, chemicals and dilute acids in the temperature range –50°C to +90°C. Other sealing materials can be used, increasing temperature range to greater than 90°C. These materials are available on request.

Klamflex Gaskets and Epoxy coatings are certified non toxic for potable water in accor-dance with BS 6920.

KLAMFLEX CENTRE REGISTER

The centre sleeve can be supplied with or without internal centre register studs. The registers provide a locating stop to centre the coupling which facilitates the laying of long pipe runs. Centre registers also prevent the possibility of the coupling creeping at positions where there are continual axial movements. Couplings without centre register are necessary for fitting closing lengths on a pipeline, or for withdrawing any particular length for cleaning or inspec-tion. Locating plugs may be fitted to couplings to act as removable centre registers, thus providing the advantage of both types.

KLAMFLEX Centre registers are used in couplings above ground where there may be a tendency for the coupling to creep e.g. on an incline.

KLAMFLEX Centre registers are of two types: A (from 350mm) removable, used where the coupling can be moved along the pipe to allow the pipe to be inspected, and B (all sizes) fixed, used where there is no need to remove cou-plings.

Where locating plugs are used, the setting gap should be increased by 9,5mm for sizes up to 324mm and 12.5mm for sizes above 324mm OD to avoid contact with the plugs.

One method of preventing pipe separation is the use of a harness assembly, consisting of lugs for welding to steel pipes and restraining tie rods. Cast iron pipes can sometimes be harnessed through the use of additional flanges cast onto the pipe ends.

In most cases we can also supply KLAMFLEX Flange Adaptors complete with harness assembly. Four or more flange bolts are replaced with long tie bolts.

KLAMFLEX Pipe Couplings supply the lugs, nuts, bolts and the couplings/adaptor between coupling and plinth to permit full assembly of all bolts.

Harness rods are not normally used with anchored couplings.

Anchor brackets are not designed to withstand the full longitudinal or lateral forces produced by internal pressure.

Ensure that sufficient clearance is allowed between coupling and plinth to permit full assembly of all bolts.

N.B.

N.B.

With brackets welded to the centre sleeve, couplings can be bolted directly to the supporting structure. Brackets are designed to withstand the thrust produced by maximum angularity and will support a 10m long pipe full of water (up to DN 1 500mm)

We recommend the use of locating centre registers with anchored couplings to help resist pipe movement. On steep slopes, special consideration should be given to anchorage.
