Product Features
- Manufactured to AWWA C219 under quality management systems accredited to ISO 9001: 2008, the KLAMFLEX Dedicated Couplings join pipes of the same outside diameter.
- Couplings up to 324mm OD are delivered pre-assembled.
- Larger sizes are delivered ready for site assembly on the pipe.
- KLAMFLEX Dedicated Couplings can be manufactured to suit both metric and imperial dimensions for Steel, UPVC, Ductile Iron, GRP, Fibre Cement, Stainless Steel, Aluminum Alloys and virtually all other rigid pipe materials.
- KLAMFLEX Dedicated Couplings can be manufactured with double sleeves to prevent end pull out on HDPE and GRP pipes. The sizes shown in the schedules of dimensions are for guide purposes. KLAMFLEX’s manufacturing methods enable us to supply any size, including non-standard sizes.
KLAMFLEX Dedicated Coupling
- KLAMFLEX Dedicated Couplings are pressure rated to the appropriate pipe standards. Working pressure is generally two-thirds of maximum test pressure shown in the schedules of dimensions.
- These pressures apply to a buried line with adequate thrust blocks or to pipelines above ground anchored at ends and at all changes of direction also secured against side thrust at each joint.
- KLAMFLEX Couplings, though capable of accommodating reasonable expansion and contraction, do not mechanically prevent separation of pipe ends subject to end thrust, and this must be prevented by other means.
- To prevent separation of pipe ends, harness assemblies consisting of lugs for welding to adjacent pipes and connecting tie rods can be supplied.
- Pipes must be anchored against end load, particularly when the pipeline is laid above ground.
- A buried pipeline normally needs anchoring only at abrupt changes in direction and at junctions or stop ends.
- KLAMFLEX Gaskets and Epoxy coatings are certified non- toxic for portable water in accordance with BS 6920 (WRAS approved).
