Product Description
HDPE Double wall Corrugated Culvert Krah pipe for sweage
HDPE krah pipes are produced according to the Krah spiral cross-winding extrusion process. During the production process the pipe is produced seamless and all sub-processes are continuously controlled by the integrated CPV and control visualizing software. The first layer is produced on a heated calibration mandrel, the next layers are produced cross-over accordingly on top of the previous layers. The previous layers are heated by an IR-Heating system to provide a surface temperature between 170°C and 200°C. With the help of the co-extruder the inner surface can be produced with an inspection friendly, coloured polyolefin material. The orientation of the molecules is in radial direction, which has a positive effect on the internal pressure. Another important quality advantage is, that due to the slow cooling down process no frozen stresses will occur in the pipe wall.

Features:
1.Durability-Low investment costs and a service life over 100 years reduce the operating costs.
2.Time Saving-Up to 30% savings when laying the light and flexible pipes with lengths of 6 m.
3.Maintenance-The smooth inner surface reduces the maintenance and cleaning costs considerably.
4.Hydraulics-Due to the very good hydraulic properties, smaller pipe diameters can be used compared to current traditional pipe materials.
5.Tightness-100% tight joints: No infiltration or exfiltration, no root penetration due to welded system.
6.Lengths-The standard lengths of 6 m reduces the amount of joints.
7.IntegratedE-fusion - Every pipe can have an integrated electro fusion
8.Temperature resistance-Due to the machining the application of the pipes range from -40°C to +80°C.
9.Environmental friendly-All materials can easily be recycled and lead back into the production cycle.
10.Flexibility-The pipes are secure against fracture, even in case of earth movement
11.Easy handling-Due to the low weight and the quick assembly, the pipes are very easy to handle.

11.Easy handling-Due to the low weight and the quick assembly, the pipes are very easy to handle.
Pipe End:
The pipe ends are cut in-line, in 90° angle to the pipe axis. Should electro fusion joints or bends be produced, the pipe ends are produced accordingly with socket and spigot.
Surface:
The internal and external pipe surface is smooth. Slight corrugation (especially on the outer surface), which necessarily involves variations in the wall thickness, is acceptable providing that the thickness of the pipe wall is at no point less than its given nominal value. The inner surface can be produced of electro conductive or inspection friendly coloured material.

Production Process:

During the production process the pipe is produced seamless and all sub-processes are continuously controlled by the integrated CPV and control visualizing software.

The orientation of the molecules is in radial direction, which has a positive effect on the internal pressure. Another important quality advantage is, that due to the slow cooling down process no frozen stresses will occur in the pipe wall.
Pipe Length:
The standard pipe length is 6 m (+/- 10 mm). If required, shorter pipe lengths are possible. The shortest length is 1 m.
Integration:
The electro fusion system is not based on couplings, but the electro fusion joint is an integrated part in the pipe and also in all fittings and manholes.
Application
1.Underground drainage, sewage, aeration and others in municipal construction areas;
2.Drainage for railway, highway, court and others in road engineering areas;
3.Nuclear power plants, steel mills, power plants, petrochemical plants, docks, stations;
4.Tidal flat, saline pool, riverbed, soft foundation expansive soil, earthquake zone and others in adverse environmental areas.
