Special Ended Fittings
KLAMFLEX Special Ended Steel Fittings are available in various fitting combinations, such as Bends, Tees, Reducers, and Crosses. These fittings are manufactured by welding a KLAMFLEX Half Coupling to the ends of a steel fitting. Bolts are used in the coupling joint; this ensures easy replacement of damaged fasteners.
KLAMFLEX makes use of a profile plate that is welded to the steel fitting or lugs that are welded to the coupling sleeve to accommodate the tightening process. With either option only one weld is required to fit the half coupling to the fitting.
We offer the dedicated sleeve type or ranger sleeve type arrangement. Installation is effected by simply inserting the plain ended pipe into the KLAMFLEX Half Coupling and tightening the studs. The use of these fittings will result in significant cost savings and ease of installation, as only one piece of equipment is being purchased, instead of separate fittings and coupling.

High Pressure Couplings
KLAMFLEX is currently undertaking an exercise on the design of the existing dedicated product range of Couplings, Flange Adaptors and Dismantling Joints that will enable Klamflex to supply high pressure items, in excess of a rating of 40 bar. This would include pressure diameter ratios of 50 Bar up to 2000nb, 64 Bar up to 1600nb and 100 bar up to 1400nb. Where necessary component material will be upgraded with regards to the mechanical and chemical composition as well as thicker modified and re-engineered sections would be used, to achieve the above.

RANGER COUPLINGS |
 |
|
|
KLAMFLEX 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 OD (Up to 23mm) a single KLAMFLEX Ranger Coupling can connect steel, ductile iron, UPVC, cast iron, asbestos cement and other rigid pipe materials. This eliminates
on site guesswork and stock range holdings are optimised.
The ability of KLAMFLEX Ranger Couplings to join
dissimilar pipe materials is a bonus feature in both
repair or permanent situations. |

Corrosion protection for KLAMFLEX Ranger
Products is available in Fusion Bonded Epoxy, Red
Oxide Primer and Galvanised finish as standard.
Optional coatings to customer specifications are
available on request.
KLAMFLEX Ranger Products have application in
the reticulation of potable water, waste water and
sewage as well as in the marine, mining, oil, gas and
general engineering sectors.
Moulded, circumferentially ribbed or specially
profiled gaskets, generally in EPDM or NBR materials,
provide for smooth installation by minimising
contact friction.
KLAMFLEX 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
KLAMFLEX Ranger Rubber Sealing Gaskets are
well lubricated with a suitable non-toxic soap solution
before the introduction of the pipe. This practice
should obviate the need for re-tightening the fasteners
after pressure testing, and further facilitate the seating
of the joint components.
KLAMFLEX Ranger Products can be manufactured with double or full sleeves to prevent end pullout on
PE, HDPE and GRP pipes.
