Sustainable water management and efficient waste disposal are the cornerstones of modern urbanization. Infrastructure projects require materials that offer high mechanical strength, flow efficiency, and a long service life. Since 1975, Düzgünler Plastik has been a leading manufacturer in Turkey, contributing to effective water management with its advanced corrugated pipe solutions designed to withstand the test of time and terrain.
The journey of Düzgünler Plastik began in 1975 under the leadership of Ekrem Düzgün in a modest 100 m² workshop. Through a steadfast commitment to quality and innovation, the company grew into a massive industrial powerhouse.
Expanding through Konya's Organized Industrial Zones with major investments in 1986, 1993, and 1999, the company now operates in a state-of-the-art facility covering 100,000 m² of open and 30,000 m² of closed area. Known for being the first company in Turkey to produce Plastic Column Pipes for Submersible Pumps, Düzgünler Plastik applies the same rigorous R&D and quality standards to its infrastructure division.
Manufactured from high-quality HDPE (High-Density Polyethylene) raw material, Düzgünler Plastik’s corrugated pipes are engineered for excellence. Our product line includes SN4 and SN8 stiffness classes, offering ideal solutions for sewer pipes, rainwater drainage, and cable protection systems.
Key advantages include high chemical resistance, flexibility against ground movements, and superior leak-proof performance. Unlike traditional concrete pipes, our HDPE corrugated pipes are immune to corrosion caused by sulfuric gases in sewage or acidic soils. The smooth inner surface ensures high flow velocity, preventing blockages in drainage pipes and reducing maintenance costs.
In global civil engineering forums (such as CivilEngCom or Infrastructure Daily), a recurring topic is "pipe failure and infiltration."
A relevant post by a Senior Project Manager on an international infrastructure forum highlights the importance of material selection:
"The most expensive part of a sewage project isn't the pipe; it's the excavation and reinstatement. We once had a project where sub-standard double-wall pipes were used to save budget. Within two years, ground settling caused the pipes to ovalize and crack, leading to groundwater infiltration. We had to dig everything up. Now, we strictly specify HDPE pipes with SN8 rating from reputable manufacturers like Düzgünler that use Triplex technology. It’s the only way to ensure the system lasts 50+ years."
This aligns perfectly with Düzgünler Plastik’s manufacturing philosophy. Our double wall corrugated pipes feature a specialized gasket system that ensures fast, safe, and watertight assembly. Whether used as sewerage pipes or for stormwater management, our products offer a reliable and economic choice for contractors and municipalities.
Producing in compliance with national and international quality standards, Düzgünler Plastik delivers long-term solutions for infrastructure needs. Our commitment to durability and environmental protection ensures that your projects rest on a solid foundation.

These classes indicate the ring stiffness of the pipe. SN8 pipes have a higher resistance to external loads and traffic pressure compared to SN4. Typically, SN8 is used under roads with heavy traffic, while SN4 is suitable for green areas or pedestrian zones.
HDPE (High-Density Polyethylene) provides excellent resistance to chemical corrosion, abrasion, and impact. It is lightweight, flexible enough to withstand ground shifts (like earthquakes) without cracking, and has a smooth hydraulic surface that improves flow.
Düzgünler Plastik corrugated pipes feature a bell-and-spigot connection with a specialized elastomeric gasket (seal). This system allows for rapid installation in the trench and ensures a watertight seal, preventing leakage into or out of the system.
