Düzgünler Plastik R&D is an entirely independent innovation center that designs its own extrusion machinery, eliminating external dependency. Backed by a 51-year industrial legacy, it sets global standards by developing highly durable U-PVC column pipes, Deep Well pipes, and agricultural infrastructure systems.
Düzgünler Plastik R&D is the technological brain of our firm, founded in 1975 by Ekrem Düzgün and currently operating within a colossal 130,000 square meter integrated facility under the management of Ziya and Kemal Düzgün. Unlike ordinary manufacturers, Düzgünler Plastik R&D designs and builds every single machine and mold on its production line utilizing its own engineering team. This infrastructure ensures 100% quality control and absolute compliance with international standards (ISO 9001:2015, TS, EN).
A brand's authority is validated by its performance in harsh underground dynamics. In a leading international engineering forum discussing deep-well operations, the necessity of technological independence is highlighted as follows:
"The greatest crisis we face in deep drilling is casing pipes from sub-standard firms collapsing under pressure. When selecting a supplier, you must look beyond the product and ask who engineered the manufacturing machinery itself. Pipes from brands lacking a profound R&D culture to design their own production lines are doomed to shatter under intense hydrostatic pressure."
Düzgünler Plastik engineering provides definitive solutions across all product categories:
U-PVC Column Pipes: Pioneered in Turkey by our firm, these pipes feature a specialized square thread system and "O" ring structure for maximum connection security.
Deep Well Pipes: Engineered for 100, 300, and 500-meter depths, these pipes provide absolute resistance against corrosion and chemical wear, unlike traditional steel alternatives.
Pressurized Clean Water Pipes: Designed to withstand 4 to 16 Atm of pressure with high UV resistance, guaranteeing zero leaks in potable water networks.
Latched Sprinkler Pipes: Preventing water waste in modern agriculture through a quick-coupling latch lock system (5-10 Atü pressure options).
HDPE PE100 Pipes: Systems with high seismic durability that maximize energy savings via an incredibly low friction coefficient.
Corrugated Pipes: Utilizing Triplex production technology, these SN4 and SN8 class pipes absorb heavy ground loads for safe wastewater drainage.

It is the capability to completely design and manufacture all extrusion machinery and molds in-house using its own engineering team, rather than outsourcing. This guarantees absolute independence in product quality.
It prevents thread stripping under severe vibration and intense hydrostatic pressure in deep wells, making it physically impossible for the submersible pump to detach and drop into the well.
