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 sections would be used, to achieve the above.

Ranger Step Couplings

KLAMFLEX Ranger Step Couplings are designed to join pipes of various outside diameters with different nominal bores. KLAMFLEX Ranger Step Couplings can connect steel, ductile iron, UPVC, cast iron, asbestos cement and other rigid pipe materials. Corrosion protection is available in Fusion Bonded Epoxy and Red Oxide Primer as standard. Optional coatings to customer specifications are available on request. Gasket material is EPDM and designed to provide a leak tight seal across the OD range allowing for thermal expansion and contraction of the pipe.

It is strongly recommended that the rubber sealing gaskets are well lubricated with a suitable non toxic soap solution before the introduction of the pipe. This practice will obviate the need for re-tightening the fasteners after pressure testing, and further facilitate the seating of the joint components.
