Gravity Pipes

  • Integrated socket and spigot

  • Diameters range from DN/ID 300mm to DN/ID 4000mm

  • Lengths range from 1m up to 6m and longer on special request

  • Black from outside yellow from inside.

  • Have a long failure-free and cost-efficient service life

  • Have a slow rate of depreciation (i.e. over 50 years)

  • Have low maintenance costs (such as cleaning)

  • Are light-weight, durable and easily extendable

  • Are 100% recyclable and environmentally friendly

  • Even under heavy load conditions Krah pipes and manholes hardly get damaged in contrast to rigid materials

  • Most damages occur due to loads

  • Flexible pipes deform in case of over-load and release the loads to the ground

  • The result is a change of the cross-section, but pipes remain leak tight and flow-capacity is almost optimal

  • By using profiled design 65% of the weight can be saved compared to equivalent solid wall pipes with the same statical capacity.
