Düzgünler Plastik is one of Turkey's leading plastic pipe manufacturers, producing solutions for every need from agricultural irrigation to water infrastructure since 1975. With a product family spanning column pipes, corrugated pipes, HDPE PE100 pipes, deep well pipes, latched sprinkler pipes, and pressurized clean water pipes, the company provides infrastructure for projects across Turkey and in more than 40 countries worldwide.
In this article, you will find the company's 51-year growth story, its product portfolio, and a clear explanation of what each product category solves.
Düzgünler Plastik is a Turkish manufacturing company founded in Konya in 1975 by Ekrem Düzgün in the agricultural machinery. Today, under the management of his sons Ziya Düzgün and Kemal Düzgün, it is one of the pioneering companies in the plastic pipe sector.
The company's growth trajectory is significant: production that began in a 100 m² enclosed space has now reached 100,000 m² of open and 30,000 m² of enclosed area. Düzgünler Plastik achieved a national first by manufacturing the Submersible Pump U-PVC Plastic Column Pipe in Turkey, and its dedicated R&D department designs and builds all production-line machinery in-house.
1975: Agricultural machinery production, 100 m² enclosed space
1986: Steel pipe and automotive spare parts in Konya 1st OIZ, 1,100 m²
1993: Automotive and machine gear production, 2,400 m²
1996–1999: Transition to plastic pipe in Konya 3rd OIZ, 8,000 m² enclosed
2001–2008: Additional investments expand to 30,000 m² enclosed, 100,000 m² open
Turkey's first: U-PVC Submersible Pump Column Pipe production
The company produces across six main product categories, each addressing a specific segment of water infrastructure. All products are manufactured in compliance with relevant Turkish Standards (TS) and international quality certifications, including ISO 9001 and TS EN 12201.
A column pipe is the plastic pipe system that enables submersible pumps to transport water from the well to the surface. Düzgünler Plastik's U-PVC column pipes are available in four models: Medium Plus, Standard Plus, Heavy, and Super Heavy. The proprietary square thread system and O-ring seal deliver leak-proof connections at depth. ISO 9001-certified production makes these pipes suitable for both residential boreholes and large-scale irrigation projects.
Deep well pipes are plastic casing pipes used to access underground water sources and line the borehole wall. Düzgünler Plastik's U-PVC deep well pipes come in 100, 300, and 500 metre depth options. Produced in accordance with TS 11794 and ISO 9001:2015, they deliver high resistance to corrosion, decay, and chemical wear. Plain and slotted options accommodate different soil and groundwater conditions on professional drilling projects.
Latched sprinkler pipes are PE-based pipes used to build field irrigation systems with rapid connection capability. Available in 5, 6, 8, and 10-bar pressure options, they accommodate different terrain and crop types. The latch lock system ensures fast installation and a leak-proof connection, while UV resistance provides long service life in outdoor conditions. Produced to TS EN 12201-3, these pipes are engineered for sustainable agriculture.
HDPE PE100 pipes are high-density polyethylene pipes used in drinking water mains, clean water transmission lines, and agricultural irrigation projects. TS EN 12201-2 and ISO 9001:2015-certified production provides superior resistance to high pressure, chemicals, and UV exposure. Available in coil and straight pipe formats, low friction coefficient enables energy-efficient system design.
A corrugated pipe is a double-wall HDPE plastic drainage pipe with high external load-bearing capacity. Düzgünler Plastik's SN4 and SN8 class corrugated pipes are used in domestic and industrial wastewater disposal, stormwater drainage, and cable protection. The gasket-seal structure enables fast, secure installation; Triplex production technology delivers maximum mechanical strength. Resistance to ground movement makes them a preferred choice in infrastructure projects in seismic zones.
Pressurized clean water pipes are TS and ISO certified U-PVC pipes for drinking water and water main projects. Available in socket, solvent-weld, and gooseneck variants at 4 to 16 bar pressure ratings, they provide practical connections for different installation scenarios. UV and chemical resistance support long-life, low-maintenance water infrastructure.

A corrugated pipe is a double-wall HDPE plastic pipe with high external load-bearing capacity used for domestic and industrial wastewater drainage, stormwater management, and cable protection. SN4 and SN8 stiffness classes accommodate different installation depths and load requirements.
A column pipe connects to a submersible pump inside the borehole and carries water to the surface. A deep well pipe is a casing pipe that lines and supports the borehole wall. Both are manufactured by Düzgünler Plastik in a range of diameters and depth options.
HDPE PE100 pipes are used in drinking water mains, agricultural irrigation networks, industrial water conveyance systems, and subsea pipeline projects. Their resistance to high pressure and chemicals, combined with a broad range of diameters and SDR options, makes them a universal solution across engineering disciplines.
Düzgünler Plastik latched sprinkler pipes are produced in 5, 6, 8, and 10 bar pressure options. The correct pressure class is selected based on the pump capacity, terrain gradient, and pipeline length of the specific irrigation system.
Yes. Düzgünler Plastik exports to more than 40 countries. Its broad product portfolio — spanning agricultural irrigation to clean water infrastructure — serves global projects beyond Turkey's borders.
Düzgünler Plastik corrugated pipes are available in a range of nominal diameters. Common sizes include 110 mm, 160 mm, 200 mm, 300 mm, 600 mm, and 1000 mm. Contact the sales team for the full dimension and availability schedule.
Düzgünler Plastik column pipes are manufactured from rigid U-PVC (unplasticized polyvinyl chloride), which provides high resistance to corrosion, chemicals, and heavy loads in deep borehole environments.
Düzgünler Plastik U-PVC deep well pipes are produced for 100, 300, and 500 metre depth applications. The 500-metre option is selected for deep aquifer drilling projects.
Yes. Düzgünler Plastik HDPE PE100 pipes are produced in accordance with TS EN 12201-2 and ISO 9001:2015, certifying them for potable water and drinking water infrastructure applications.
