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.
