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
