Advantages, Considerations, Frequently Asked Questions


Because its is polyethylene and polyproyplene, it shows high resistance to corrosion.

Its guaranteed life against outer impacts is 50 years at least and it can be used for 100 years.

Because plastics are hydrolic smoothless, they show little resistance to fluid and the fluid flows with more occupancy. This decreases project costs due to selection of one sub diameter group within the project.

There is no loss of product during application.

Because its density is very low compared to concrete and cast, need for business machine goes down to minimum levels.

It does not allow contamination of ground water and soil by depletion because its wear resistance is high.

Even if the ground is covered with gravel, it flexes and prevents breaking.

It does not allow these trees to leak to the channel and choke it.

All joining parts allow special product to be produced for the project.

It does not leak even 4 bar pressure when joined with electrofusion, not dispersed by removing from its place.

It is not deactivated by being affected the shakes in the earthquake and breaking.

It can be used in transition of river, lake and sea.

It can be used in evacuation of pre treated water taken from treatment plants till marine streams of water.


Compression should be performed layer by layer to avoid any remaining space around the pipes while filling the channel. Make sure that bottom of the pipe is filled especially with filling material. If filling is performed by compressing well according to specification it fulfills its duty for its whole life as traffic and earth load coming to pipe are transferred to the filling. Otherwise, when there is space, the pipe carries in line with its capacity, collapses when it can not find any place to transfer above its forces. The same situation is also valid for steel pipes. Sliders such as soap and silicon should be used to insert pipes into fitting in sealed systems. Whether surfaces are clean or not should be controlled before electrofusion welding. Make sure that wires do not contact each other before welding. Service Life is 50 years under 0,5 bar pressure. It is not affected by Ultraviolet rays coming from sun because it is manufactured as carbon black.

Frequently Asked Questions

1. What is its raw material?

It is produced from Polyethylene (PE) and Polypropylene (PP) raw material. PP gives more SR (ring resistance) value at the same wall thickness.

2. Why is it produced as ribbed?

When a load is put on an object with a certain thickness, the outer layer carried the most load. This value becomes zero in the center. Material of the part carrtying less load is saved. Pipe weight decreases in significant amount.

3. How many floors does the pipe have?

Those produced as monolithic consist of two layers. Rib formation is given to the outer layer. They can be manufactured in different profiles and many layers according to project in spirals.

4. What are the joining methods?

Corrugated pipes are joined till 450 diameter with sealed method. Spiral pipes are joined with electrofusion welds providing to use extrusion weld and till 4 bar pressure in upper diameters.
