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.

ADVANTAGES
The KLAMFLEX Coupling is a mechanical pipe joint consisting of a centre sleeve, end flanges, wedge-shaped rubber sealing rings, nuts and bolts. The main components are constructed from high quality SG iron for small sizes and hot rolled profiled steel for large sizes.

Klamflex Couplings provide a leak-tight pipe joint through the tightening of bolts which draw the flanges together and compress the sealing rings in the recess between the sleeve and each end flange onto the pipe.

The leak-tightness of the Coupling is assured if all bolts are fully tightened, and subsequent inspection by gamma ray, x-ray, ultrasonic or other forms of non-destructive testing is not required. Couplings can be set to take angular deflections of 6° in any plane on sizes up to 457mm OD reducing to 1° at 1820mm OD (for flange adaptors, acceptable deflections are half these values).

External and internal pipe protection coatings are unaffected by fitting Couplings. KLAMFLEX Couplings used throughout a pipeline will take care of expansion and contraction and limited ground movement when standard pipe lengths are used.

Stresses at valves and other fixed points are also relieved by using KLAMFLEX Flange Adaptors and Couplings.

Couplings are manufactured to suit both Imperial and Metric dimensions for pipes in:
• STEEL • UPVC • DUCTILE IRON • FIBRE CEMENT • G.R.P. • STAINLESS STEEL • ALUMINIUM ALLOYS.

The short time taken to assemble Couplings compares favourably with any other form of jointing. KLAMFLEX Step Couplings facilitate joining pipes of different specifications:
i.e. Different pipe outside diameters; Different pipe materials (Steel, Cast Iron, Fibre Cement).
