Restrained flange adaptor RKS-FL-E

INDEX NO. 354

APPLICATION

Intended for mechanical connection of plain end of pipe with flanged fittings in waterworks, wastewater and other systems for liquids chemically neutral. Equipped with rims protecting againt sliding a pipe out of an adaptor. Used for iron, steel, plastic, GRP and AC pipes.

DESIGN FEATURES

  • diameter range DN250-1200 mm
  • adaptor 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 an adaptor according to individual customer needs: nonstandard height, made of different materials, e.g. stainless steel
  • prevents a pipe from sliding out of an adaptor
  • the design of protection depends on the pipe material and pressure
  • reinforced construction for heavier working conditions and increased product life
