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.
