DEDICATED COUPLINGDEDICATED COUPLING
DEDICATED STEP COUPLINGDEDICATED STEP COUPLING
One method of preventing pipe separation is the use of a harness assem-bly, 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.
KLAMFLEX HARNESSED COUPLINGS
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 cou-plings to help resist pipe movement. On steep slopes, special consideration should be given to anchorage.
KLAMFLEX ANCHORED COUPLINGS
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.
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 couplings.
Klamflex Dedicated Step Couplings are supplied where pipe ends of different outside diameters have to be connected, Step Couplings will also accommo-date the different outside diameters of pipes with different materials of construction with a common nominal bore.
Sizes: 50 - 2000NBWorking Pressure 16 Bar (Please consult Klamflex for pressures up to 40 Bar)
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.
Sizes: 50-2000NB (Please contact Klamflex for sizes above 2000NB)Working Pressure 16 Bar (Please consult Klamflex for pressures up to 40 Bar)

Klamflex Ranger Flange Adaptors are designed to join pipes of various outside diameters to flanged valves, pumps, flow meters, flanged pipes and fittings. Ranger Flange Adaptors are manufactured using a multi drilled flange to accommodate most drilling tables.
Sizes 50 - 600NBMax Working Pressure 16 Bar
Klamflex Dedicated Flange Adaptors are manufactured to join plain ended pipe to flanged valves, pumps, flow meters, flanged pipes and fittings. The thickness of the flanges will not necessarily be the same as the mating flange due to the fact that the flange of the Flange Adaptor will not be subject to the full end or side thrust, most of which is absorbed by the flexibility of the rubber gasket. Dedicated Flange Adaptors can also be restrained to alleviate end pullout.

REPAIR CLAMPS -SIZES
Klamflex Repair Clamps (KRC) are designed with a UNIQUE 2 STAGE sealing arrangement to provide a repair means for small leaks in Steel, PVC, HDPE, DI & AC pipelines.
The UNIQUE 2 STAGE sealing arrangement provides superior sealing capabilities enabling leaking pipes to be repaired more effectively and efficiently on site.
Klamflex uses only 16 REPAIR CLAMPS to accommodate pipe outside diameters from 48 to 380mm, making stocking more economical.
The KRC is rated to a maximum working pressure of 16 bar for pipe outside diameters of less than 234mm and 12 bar for pipe outside diameters over 234mm.
