Couplings

Couplings

Couplings are applicable to a wide variety of pipe diameters and materials. Our ability to customize couplings through engineering practices is a proven solution that supports the expansion and maintenance of piping networks.

The customized standard

Our couplings are based on techniques and designs which have been exercised for over 20 years in different types of applications and industries. We provide both flexibility and reliability when supporting our customers’ infrastructure and maintenance projects by applying customized concepts.
Within our product range, we distinguish between:

Maxi wide range coupling - Type WR-Max

This maxi coupling has a wider range than most available standards. It can be used as a reduced or straight coupling, or flange adaptor for water and sewage pipes. Another feature is that it is compatible with both an external and internal connection.

  • Range 40 mm
  • Resicoat® Epoxy coating (also available in stainless steel)
  • Rubber EPDM 65°shore A.
  • Applicable to:
    • Cast iron
    • Steel
    • Asbestos cement
    • Concrete/ Cement
    • PVC/ PE (in combination with
      support bush)
    • GVK
  • Working pressure:
    • Up to DN1000 Max. 16 Bar
    • DN1000 until DN1500 Max. 10 Bar
    • Greater than DN1500 Max. 6 Bar
    • Temperature: – 30° to max 70° C


locking mechanism - WR-MAX

Wide range coupling - Type WR
