Repair Clamps
One-piece Repair Clamp 44-330 mm



- the clamp cannot be used for different pipe diameters (transitions)
- radial length of damaged area max. 20% of pipe outside diameters
- the repair clamp must be centred over the damaged area
- R = maximum axial length of damaged area
- test pressure = 1.5 x PS
- comply with installation instructions

One and two-piece Repair Clamps for the safe and reliable repair of gas, water and
drainage pipes made from various materials.
Applications
- Repair Clamps for sealing damaged gas, water and drainage pipes made from cast iron,
fiber coment or PVC - sizes from DN 40 to DN 400
- with standard NBR sealing sleeve
Working instructions
- the repair clamp must be at least as long as the outside diameter of the pipe being repaired
Gas pipes: permitted working pressure 5 bar (< DN 300)
Water pipes: permitted working pressure
< DN 200 PN 16
> DN 200 PN 10
> DN 300 on request
General
- made from stainless steel
- ideal for repairing large damaged areas up to 250 mm long
- the large-surface waffle profile of the sealing sleeve reduces the required tightening torque, extending the life of the NBR material
- integrated ergonomic hand grips for easy handling
- no loose screws or parts when opening
- both the one-piece and two-piece Repair Clamps are complete units
- modern manufacturing methods, including pressure jointing, prevent changes in the material structure and stresses in the material
- the Stainless Steel screws are permanently coated with Molykote, which prevents erosion
of the screws and also greatly reduces the torque required - installation with standard tools (torque wrench with hex socket) – without extensions
