PE Pressure & Non Pressure Structured Wall Pipes up to Ø4000mm |
Over the last decades the inherent weakness of concrete, clay, ductile, PVC and steel caused tremendous problems in existing sewer piping systems, as they tend to be brittle or are too sensitive to aggressive chemicals and soil conditions. Failures had become a common occurrence worldwide in sewer and other large-diameter-pipe applications. In addition they have a unprofitable relation between cost and benefit.
So Krah derived benefit from the fact that the processing of polyolefin's is very easy and the plastic materials provide superior properties against adverse effects of the ambient and the chemicals.
In addition to the permanent solution that lasts through generations. Krah piping system is able to provide everlasting and economic solutions in wide-ranging fields of applications as for example drain, storm-drain and sewer systems as well as sea outfall, manholes and reservoirs.
Krah AG - Pressure & Non-Pressure Piping Systems
Krah can produce two kinds of pipes
1. PE-GFR Pressure Pipes upto 16 bars
2. Non and Low Pressure Pipes
Pipes are produced according to the Krah-Spiral-Cross-Winding-Extrusion-Process.
It can produce pipe systems upto max. diameter 4000 mm with a pipe length of 6 meters & max. solid wall thickness of 200 mm.

The advantages at a glance:
| Durability |
| • |
Low investment costs and a service life over 100 years reduce the operating costs |
| Time saving |
| • |
Up to 30% savings when laying the light and flexible pipes with lengths of 6 m |
| Maintenance |
| • |
The smooth inner surface reduces the maintenance and cleaning costs considerably |
| Hydraulics |
| • |
Due to the very good hydraulic properties, smaller pipe diameters can be used compared to current traditional pipe materials |
| Tightness |
| • |
100% tight joints: No infiltration or exfiltration, no root penetration due to welded system |
| Lengths |
| • |
The standard lengths of 6 m reduces the amount of joints |
| Integrated E– fusion |
| • |
A complete pipe system is always just as secure as its weakest component. The weakest component is the joint |
| • |
Every pipe can have an integrated electro fusion |
| Temperature resistance |
| • |
Due to the machining the application of the pipes range from -400C to +800C |
| Environmental friendly |
| • |
All materials can easily be recycled and lead back into the production cycle |
| Flexibility |
| • |
The pipes are secure against fracture, even in case of earth movement |
| Specific light weight |
| • |
The Krah pipes have a very low weight and therefore are easy to handle during installation, which makes the usage of a crane on site in most of the cases unnecessary |
| • |
By using profiled pipes we can safe weight up to 65% compared to equivalent solid wall pipes with the same statical capacity |
