RSO repair clamp ROMACON RSO repair clamp

The clamps can be used to repair the following pipe types:

  • Ductile Iron (DI)
  • Cast Iron (CI)
  • Steel (St.)
  • Asbestos Cement (AC)
  • PE coated steel
  • PVC*
  • GRP*
  • PE*

* If pipe repair clamps are to be used on plastic pipes, please always contact Romacon or a Romacon distributor for more information regarding the application and restrictions on these pipe types.

Romacon repair clamps should be used under following conditions:

  • For PVC pipes, the width of the clamps should be 50 % longer and bolt torque should be reduced by 50 %. We prefer that you consult your Romacon distributor. 
  • The maximum allowable distance between two pipe ends should not exceed 10 mm.
  • The maximum allowable deflection is 2 degrees.
  • The maximum allowable o!set should not exceed 3 mm.

Material specification:

  • All metal parts: stainless steel AISI 304.
  • Metal parts have been deburred and are passivated to restore the corrosion resistance to its original state after the welding process.
  • Single band (one section) with a workingrange of max. 4 mm. For an overview of all working ranges please see our price-list.
  • Standard certified rubber gaskets EPDM or NBR. The rubber is tapered and has a waffle pattern.
  • Seamless rubber lining for every clamp diameter.
  • Bridge plate is vulcanized into the rubber gasket.
  • U-shaped lifter bar.
  • Stainless steel, electrolytic zinc plated nuts to prevent galling.
  • Stainless steel washers.
  • No loose parts that may get lost during installation.
  • No special tools required: a simple wrench will do the job.
  • Special tape is used to fix the rubber gasket to the stainless steel band. This tape is flexible and reinforced with glass fibre thread to withstand hot and humid conditions and guarantee a long storage capability.
  • Under most circumstances the clamps can be installed without releasing the pressure on the pipe.
  • The clamps are packed into strong double-rib cartons. For export overseas we use strong, seaworthy crates.
