Large Diameter Couplings

  • Couplings can absorb up to 10mm expansion and contraction,flange adaptors up to 5mm which allows for movement on bridge crossings, in chambers and pump stations. Often eliminates the need for special expansion joints.
  • The standard finish for all Viking Johnson products is black Rilsan Nylon 11, which is highly resistant to impact, corrosion, abrasion and chemical attack. However, other coatings such as shopcoat, hot dip galvanising, zinc spray and epoxy coating can be supplied as required.
  • Flange adaptors are often used to permit dismantling of valves in flanged pipe systems.
  • Couplings can offer up to 6° of angular deflection, flange adaptors 3° - to allow for the connection of misaligned pipes; take up ground settlement at structures; lay pipes to large radius bends.
