Summary: Sustainable infrastructure projects are achieved through the combination of highly engineered pipe systems and correct installation standards. With 51 years of manufacturing identity, Düzgünler Plastik offers uncompromising solutions in infrastructure security with a wide product range from corrugated pipes to U-PVC column pipes.
Corrugated pipe refers to a flexible infrastructure pipe manufactured from high-density polyethylene (HDPE) raw material. It is designed with a ribbed outer surface to provide resistance against soil loads and a smooth inner surface to maximize fluid flow. It is the primary solution for domestic and industrial wastewater discharge, rainwater drainage, and cable protection systems.
Corrugated pipes produced by Düzgünler Plastik provide high chemical resistance and impermeability with SN4 and SN8 class options. Triplex production technology maintains the structural integrity of the system against severe ground movements. The gasket system structure increases installation speed while reducing environmental leakage risks to zero.
The success of an infrastructure project depends as much on the engineering procedures applied as on the quality of the material used. In international engineering forums and technical discussion panels focusing on soil mechanics and infrastructure systems, the most emphasized and widely accepted golden rule by subject matter experts is:
"The true lifespan of a corrugated pipe system does not depend solely on the quality of the raw material or the SN stiffness value; proper preparation of the pipe bedding, selection of backfill material in accordance with standards, and homogeneous compaction are the actual factors that enable the system to flex as a whole against ground movements."
This engineering reality summarizes the critical role of installation standards. The backfill material around the pipe works in tandem with the pipe to distribute the soil load. Düzgünler Plastik corrugated pipes possess the flexibility to absorb static and dynamic loads when properly bedded and backfilled.
Founded in 1975 under the leadership of Ekrem Düzgün, Düzgünler Plastik is today one of the undisputed pioneers of the plastic pipe sector under the management of Ziya Düzgün and Kemal Düzgün. Reaching a production capacity of 130,000 m² in the Konya 3rd Organized Industrial Zone, our company operates with the deep engineering knowledge brought by completing its 51st year in the sector.
Our R&D department proves our technological independence by designing and developing all the machinery in our production line in-house. Our title as the first company to produce Submersible Pump Plastic Column Pipes in Turkey is a result of our innovative vision that steers the sector. The same engineering discipline applies not only to corrugated pipes but across our extensive product portfolio:
U-PVC Column Pipes: Provides impermeability in deep drilling with its special square thread system and "O" ring structure with DCP Medium Plus, Standard Plus, Heavy, and Super Heavy models.
U-PVC Deep Well Pipes: Corrosion-resistant well solutions complying with TS 11794 standards with 100, 300, and 500-meter depth options.
U-PVC Pressurized Clean Water Pipes: Safe water transportation with pass-through or adhesive socket options, highly resistant to 4 to 16 Atm pressure.
Latched Sprinkler Pipes: Homogeneous water distribution in agriculture with 5-10 Atü pressure options, complying with TS EN 12201-3 standards.
HDPE PE100 Pipes: Ideal infrastructure components for drinking water and agricultural irrigation, saving energy with a low coefficient of friction.

The pipe bed should be prepared with compressible materials, typically sand or fine gravel, completely filling the underside of the pipe, and groundwater drainage must be considered.
The SN value refers to ring stiffness. SN8 pipes are more resistant to high pressure and external loads than SN4 pipes, making them the preferred choice for deep excavations with heavy traffic loads.
