RANGER COUPLINGS
RANGER products, in the form of wide range couplings and flange adaptors, are designed to join pipes of various outside diameters with the same or different nominal bore.
Because of the wide range tolerance on O.D. (Up to 23mm) a single RANGER coupling can connect steel, ductile iron, UPVC, cast iron, asbestos cement and other rigid pipe materials.
RANGER Flange adaptors facilitate the connection of plain ended pipe to flanged ancilliary products , in the same range of outside diameters, and multi drill-ing flanges further simplify installation.
The ability of RANGER couplings to join dissimilar pipe materials is a bonus feature in both repair or permanent situations.
Corrosion protection for RANGER products is avail-able in Fusion Bonded Epoxy, Red Oxide Primer and Galvanised finish as standard. Optional coatings to customer specifications are available on request.
RANGER products have application in the reticula-tion of potable water, waste water and sewage as well as in the marine, mining, oil, gas and general engi-neering sectors.
Because of the RANGER’S wide range tolerance on pipe O.D., on site guesswork is eliminated and stock range holdings are optimised.
Moulded, circumferentially ribbed or specially profiled gaskets, generally in EPDM or NBR materi-als, provide for smooth installation by minimising contact friction.
RANGER gaskets are designed to provide a leak tight seal across the O.D. range per nominal size and still allow for thermal expansion and contraction of the pipe up to 5mm per gasket, facilitated through gasket deformation.
To facilitate installation and avoid possible creep under rising load, it is strongly recommended that the RANGER rubber sealing gaskets are well lubricated with a suitable non toxic soap solution before the introduction of the pipe. This practice should obvi-ate the need for re tightening the fasteners after pres-sure testing, and further facilitate the seating of the joint components.

KLAMFLEX straight 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.

The sizes shown in the schedules of dimensions are for gu ide pu rposes . KLAMFLEX coup l ings 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.Sealing rings are of a natural rubber and are suitable for water and sewerage services, chemicals and dilute acids in the temperature range –50°C to +65°C. Other sealing materials can be used, increasing temperature range to greater than 100°C. These materials are available on request.Klamflex Gaskets and Epoxy coatings are certified non toxic for potable water in accordance with BS 6920.
KLAMFLEX couplings, though capable of accommodating reasonable expansion and contraction, 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.
resulting from temperature variations, experienced under normal atmospheric conditions. The resistance to pipe end separation offered by couplings is dependent upon the number of variable installation factors such as pipe surface, pipe tolerance, coupling component tolerances, etc. and is thus different for every case. For complete safety it is advisable to assume that the worst conditions prevail for each installation.
Galvanised bolts are supplied as standard.Stainless steel bolts are available on request.
Couplings up to 324mm OD M12 bolts – 65-80Nm.Couplings over 324mm OD M16 bolts – 80-120 Nm.
These torque figures relate to 16 bar working pressure.
Each KLAMFLEX coupling will accommodate maximum pipe movement of 10mm and each flange adaptor 5mm. This is achieved by deformation of the sealing ring, not by a sliding action of the ring on the pipe. This will cater for expansion and contraction

CENTRE REGISTER
PIPE MOVEMENT
EXPANSION AND CONTRACTION
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 inspection. Locating plugs may be fitted to couplings to act as removable centre registers, thus providing the advantage of both types.
THE SETTING GAP IS THE DISTANCE BETWEEN THE PIPE ENDS AFTER THE COUPLING HAS BEEN ASSEMBLED.
WHERE LOCATING PLUGS ARE USED, THE SETTING GAP SHOULD BE INCREASED BY 9,5mm FOR SIZES UP TO 324mm OD AND 12,5mm FOR SIZES ABOVE 324mm OD TO AVOID CONTACT WITH THE PLUGS.
KLAMFLEX STRAIGHT COUPLINGS ARE AVAILABLE IN SIZES UP TO 3,5m, FOR DETAILS CONTACT OUR ENGINEERING DEPARTMENT
EACH COUPLING WILL ALLOW FOR A SETTING ANGULARITY AS FOLLOWS:
THE ABOVE SCHEDULE SHOULD ONLY BE USED WHEN THE PIPES WILL NOT MOVE IN SERVICE. WHERE MOVEMENT OF THE PIPES MAY OCCUR SUBSEQUENT TO LAYING, WE RECOMMEND WORKING TO HALF THESE FIGURES TO ALLOW FOR IN-SERVICE FLEXIBILITY.
Pipe ends should be smooth, with no seams, score marks, dents or ovality beyond those detailed in. BS534-1990 Section 15 (See Design consideration leaflet).

STEPPED COUPLINGS
Where pipe ends of different outside diameters have to be connected, stepped couplings can be provided. These normally cover the difference between the outside diameters of pipes of different materials having a common nominal bore, or pipes of the same materials having different nominal bores.
PIPE MOVEMENTIt is advisable to mark the pipe a known distance from the end when fitting a step coupling to enable inspection of movement. This will allow the inspector to ensure that no telescoping along the smaller diameter pipe has occurred.NB: When this fitting is used as a coupling
between two pipes with diameter differences exceeding 25mm it is essential to ensure that the stepped coupling cannot be forced along the smaller diameter pipe. Scheduled sizes will not normally require such precautions, but others may.Regular inspection of a pipe previously marked, is normally all that is required. Alternatively, where this cannot be arranged, a mechanical means should be employed.
PRESSURE CONSIDERATIONSPressure rating for stepped couplings are equivalent to the rating specified in the straight coupling schedules, for the larger of the two OD's. In the case of cast iron, FC and uPVC pipes, the pressure rating will match the pipe rating.
