Ductile Iron

A long established product for conveying water and sewage under pressure, ductile iron is a highly specified product. It's extremely versatile in terms of the variety of coatings available for different applications and the ground conditions it can withstand:

  • EN545 for potable water
  • EN598 for waste water and sewage
  • Flanged connections for above ground
  • Tyton push-fit for below ground
  • 80-1400mm size range
  • Valves & Couplings

Valves are required in every pressurised system as a means of isolating a section of mains, for washout, or for preventing backflow where pumps are in operation. EH Smith can offer any valve required:

  • Gate Valves
  • Non-Return valves
  • Flap Valves
  • Penstocks

Couplings and Adaptors provide flexibility in a pipe work system and a means of connecting pipes of different materials and different sizes. EH Smith offers a variety of options both off the shelf and made to order:

  • Straight couplings 50mm-2000mm
  • Flange adaptors
  • Self anchoring
  • Repair clamps
  • Wraparound couplings for 'out of round' pipes
