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.
