Accessing groundwater is an operation that pushes the boundaries of engineering knowledge and material quality. Especially in wells exceeding 300 meters in depth, soil pressure and underground movements test the strength of the pipe used. Düzgünler Plastik, a pioneer of Turkish industry since 1975, offers definitive solutions to "collapse" and "corrosion" problems encountered in deep wells with its advanced borewell pipe technologies.
Success is not a coincidence, it is accumulation. Founded in 1975 under the leadership of Ekrem Düzgün in a humble 100 m² workshop, Düzgünler Plastik has transformed into a giant integrated facility with 100,000 m² of open and 30,000 m² of closed area.
Acting with the principle of "Quality First", our company became the leader of innovation in the sector by producing the First Submersible Pump Plastic Column Pipes in Turkey. Today, it maintains the same leadership with U-PVC Deep Well Pipes that can withstand depths of up to 500 meters.
As depth increases, the external pressure (hydrostatic pressure and soil load) acting on the pipe increases exponentially. At this point, ordinary pipes can ovalize, trapping the pump, or collapse completely.
Düzgünler Plastik's U-PVC deep well pipe is specially formulated for deep wells.
High Strength: Our pipes, produced according to 100, 300, and 500-meter depth classes, are compliant with TS 11794 and ISO 9001:2015 standards and are resistant to high external pressure.
Corrosion Resistance: While metal pipes rust and rot over time, plastic borewell pipes are guaranteed for life against chemical wear.
Filter Structure: Our screen casing pipes (strainer pipes) extend the life of the well by filtering sand and sediment without reducing the water flow rate.
In technical forums where drillers and engineers meet, the biggest concern is "collapse resistance."
A warning from a drilling engineer named 'DeepDrill_Pro' on a global drilling forum highlights the importance of quality:
"Friends, especially after passing 200 meters, do not use unbranded blue pipes with low wall thickness just to be 'economical'. In a project last month, a 350-meter well closed up at 280 meters due to poor quality pipe, and the pump was stuck inside. Soil at that depth is no joke. Use certified goods from corporate firms like Düzgünler that have a 500-meter series and comply with standards. You open the well once, don't risk it."
This field experience is proof of why Düzgünler Plastik never compromises on quality in the production of casing pipes and deep well pipes. For us, "durability" means maintaining form even hundreds of meters underground.
Using metal pipes in deep wells means heavy crane costs and difficult labor. However, Düzgünler Plastik well pipes are easily transported thanks to their lightweight structure and installed quickly with their special threaded structure. This reduces the total cost of your project while increasing work safety.

For depths of 300 meters and above, U-PVC borewell pipes with increased wall thickness and tested pressure resistance, specifically the "300 Meter" or "500 Meter" series, should be preferred. Düzgünler Plastik manufactures specific series for these depths.
In terms of corrosion (rust) and chemical resistance, U-PVC pipes are much more durable than steel and last a lifetime. In terms of mechanical strength, when the correct wall thickness is selected (e.g., Düzgünler 500m series), they can safely replace steel pipes.
Strainer pipes allow water to enter the well while preventing sand, gravel, and sediment formed during drilling from entering. This protects the impellers of the submersible pump and ensures clean water extraction.
