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.

Dismantling Joints
a

Manufactured to AWWA C219 under quality management systems accredited to ISO 9001:2000, the KLAMFLEX Dismantling Joint assembly is a double flanged composite fitting featuring a telescopic action between a flanged spigot and a flange adaptor. The joint is designed to provide longitudinal adjustment in flanged pipe systems. Dismantling Joints provide a simple method for the installation and removal of flanged valves, pumps, flow meters, flanged pipes and pipe fittings. Tie rods are provided for final anchoring and location and these also double as mating flange jointing bolts, reducing the number of these required.

The Dismantling Joint range from KLAMFLEX extends from 50mm to 2000mm and whilst the chart indicates flange ratings of PN10/16, all common drillings are available in pressures up to 40 BAR. The range indicated overleaf is typical and KLAMFLEX can manufacture to specific customer specifications and dimensions on request.

a
  Thickness of KLAMFLEX Flanges will not necessarily be the same as the mating flange. Flanges and Flange Adaptors will not be subject to full end or side thrust, most of which is absorbed by the flexibility in the rubber gaskets. Pipe end should be smooth, with no seams, score marks, dents or ovality.

Installation is extremely simple and is generally done with the flange adaptor end connected to the valve or other appurtenance. In cases where a full faced flange is required, for example on wafer butterfly valves, the joint is simply turned round to use the spigot flange instead.
