Pipe coupling RRS

APPLICATION

Intended for mechanical connection of plain ends of pipes in waterworks, wastewater and other systems for liquids chemically neutral. Used for iron, steel, plastic, GRP and AC pipes.

DESIGN FEATURES

• diameter range 270-2000 mm
• coupling tolerance is ± 7 mm in relation to the outer pipe diameter
• pipe angular deflection up to ± 3°
• corrosion protection:
  – epoxy coating
  – optional: hot-dip galvanized
• EPDM gasket for potable water or NBR gasket for wastewater
• threaded galvanized pins,
  optional: hot-dip galvanized, stainless steel, acidresistant steel
• eyebolt
• possibility to design and produce a coupling according to individual customer needs: nonstandard height, made of different materials, e.g. stainless steel
