It is produced in SN4 and SN8 classes according to TS EN 13476-1 and DIN 16961-16566 standards, between Ø100 and 800 diameters. It does not require extra sleeves and saves labor because it is self-muffed in all diameters. Since it is produced from polyethylene raw material; It is an ideal product for long-lasting sewage systems with corrosion resistance, high wear resistance and excellent chemical resistance. Sewer pipes are a product produced from Polypropylene and Polyethylene raw materials in the Polyolefin group. Extruded corrugated pipes produced up to Ø1000 mm diameter can be produced from polyethylene and polypropylene raw materials, while spiral corrugated pipes are produced from polyethylene. Since the ring strength value is higher in polypropylene at the same wall thickness, it is more preferred. By the spiral method, pipes with a diameter of Ø300 mm and above are produced.


Injection fittings are produced for joining extruded corrugated pipes. Gaskets are placed in the channel on the outer surface of the pipe and inserted into the fitting. Spiral corrugated pipes can be joined by electrofusion method as well as extruder welding sealed method. This joining method makes pipes that are normally used under 0.5 bar pressure usable even at 4 bar.


In this way, the pipes continue to operate without leaking and without being damaged at the joints in case of pressure increases encountered in precipitation that turns into floods.


Since the corrugated pipes are not affected by corrosion and have high abrasion and chemical resistance, they are sold with a lifetime guarantee of 50 years. Thanks to their flexible structures, they carry out their activities without being affected by ground shaking such as earthquakes.


Since the impermeability is ensured throughout the life of the pipe, contamination of groundwater and soil is prevented. It is out of question for tree roots to enter the pipe and close. With its light weight, it can be installed in small diameter pipes without the need for a construction machine.




It shows high resistance to abrasion and excellent resistance to chemicals.

It is desirable that the pipe materials used in sewage systems are not corroded and resistant to chemicals. Aggressive chemicals found both in the wastewater and in the soil have damaged the pipe material in the existing sewerage networks. Since polyethylene raw material is a corrosion resistant material, it is the ideal pipe material for long-lasting sewer systems. It can also be used for the storage and transfer of chemicals.



Corrugated pipes are very light and at the same time resistant to impacts. There is no wastage during transportation and stocking. Since its light, it can be easily put into each other and stocked or transported.






Corrugated pipes can be combined with a bush gasket or with a sleeve gasket. Head fastening can be done easily in any construction site environment. Due to its lightness in all kinds of horizontal-vertical transportation at the construction site, the need for construction equipment is minimal.




Since the corrugated pipe is light, heavy equipment is not needed during laying. Thanks to its easy joining methods, the laying speed is higher than other pipe materials. It is a pipe material used especially in urban construction sites and in areas where the construction season is short.




Sealing is provided up to a pressure of 0.5 bar in systems where the jointing method with muffle seal and sleeve seal is applied. In this way, sewage wastes do not mix with groundwater and our environment is protected. In addition, in places with high ground water, the entry of water from the outside into the sewer system is prevented. This prevents the line from overfilling and overflowing.




The design life of corrugated pipes is minimum 50 years. For this reason, operation and maintenance costs are minimal.




Since the hydraulic roughness of corrugated pipes is very low compared to other pipe materials, a lower diameter can be selected and used by optimizing the diameter in the sewer system.In this way, the project cost of laying at the construction site can be reduced compared to the concrete pipe. In addition, the smooth surface prevents the solid particles in the system from adhering to the inner surface of the pipe and the narrowing of the cross-section that may occur over time is prevented.




Since corrugated pipes are flexible, they adapt to ground movements and do not deform.

During the production of the desired length, breakage and losses are zero.Muffed pipes are produced in standard 6 m lengths. Pipes without bell can be produced in the desired length according to customer demand. Relevant standards Pr-En 13476 -1, CEN/TC 155WI 011




• It has a service life of 50 years.

• It preserves the natural properties of water and is hygienic.

• It can be produced as coil and length. It provides very fast line laying opportunity especially in coil pipes.

• On curved terrains due to its flexibility (it can be bent up to 18-50 times the pipe diameter depending on the wall thickness [it is easy and economical], it provides less elbow usage).

• It adapts to soil movements such as earthquakes and landslides.

• Offers safe and practical connection solutions.

• Modern laying techniques can be applied.

• Provides high resistance to chemicals, does not corrode.

• It is not affected by sunlight thanks to its UV additive.

• Due to the smooth inner surface of the pipe, the particles in the fluid cannot adhere to the inner surface of the pipe and there is no time-dependent cross-sectional narrowing. Provides higher flow rate.

• It does not hold algae on the inner surface of the pipes and does not produce bacteria.




There are two different production methods of corrugated pipes. They are produced in a continuous, single process extruder and on the mandrel with the helical method. The production capacity of extruded corrugated pipes is very high, and the ring strength value is constant since the shape of the product cannot be changed. Helical corrugated pipes, on the other hand, can be produced at the desired ring strength value and optimum weight depending on the project.The pipes consist of two layers, the inner tube layer and the outer rib layer. The inner layer is a flat-walled pipe that carries the fluid. The outer layer is ribbed. Both layers are molecularly linked to each other. Since the outer hollow rib structure can carry loads (close to the full structure) due to the laws of physics, it is preferred for saving raw materials and reducing the weight of the pipe.

Extruded corrugated pipes come out of the extruder in two layers and the outer layer is shaped by molds.In the spiral corrugated pipe, first the inner pipe is turned into a pipe by wrapping the polyethylene in the form of strips on top of each other in the mandrel.Afterwards, the product drawn as a profile is wrapped on the pipe and welded. Both products show a monolithic feature with their welded structure.




When filling the channel, compaction should be done layer by layer so that there is no space around the pipes. In particular, it should be ensured that the bottom of the pipe is filled with filling material. If the filling is done by compressing well according to the specification, the traffic and soil load coming to the pipe are transferred to the filling, so the pipe fulfills its duty throughout its lifetime. Otherwise, when there is a gap, the pipe carries what it can carry, and collapses when it cannot find a place to transfer the forces above it. The same is true for steel pipes.In gasketed systems, lubricants such as soap and silicone should be used to allow the pipes to enter the fitting. Before electrofusion welding, it should be checked that the surfaces are clean. Before welding, care should be taken that the wires do not touch each other.
