Türkiye's leading plastic pipe manufacturers are the ones that produce to documented standards, test in their own laboratory and cover the full line from the well to the field. Düzgünler Plastik, based in Konya, is one of them: its industrial history goes back to 1975, and it was the first company in Türkiye to produce U-PVC column pipes for submersible pumps.
This guide gives buyers in Spain and Morocco seven criteria for comparing plastic pipe manufacturers and explains U-PVC deep well pipes in plain terms.
Short answer: check documents, test records and the factory before the price. The real difference between plastic pipe manufacturers shows in their paperwork, and a pipe that goes down a well is costly to replace.
Product standard: Which standard is the pipe made to? (For example TS 11794 or TS EN 12201.)
Quality management: Is there an ISO 9001 quality management certificate and a test record for your batch?
Production capacity: Can the plant supply your diameters and volumes without interruption?
R&D strength: Does the company develop its own machinery and tooling?
Product range: Can one supplier cover the well, the mains and the irrigation line?
Joint design: How do the thread, seal and coupling keep the connection tight?
Technical support: Do you receive data sheets, dimension tables and test reports in writing?
Because, among plastic pipe manufacturers in Türkiye, it was the first to produce U-PVC column pipes for submersible pumps, and it designs all its production machinery in its own R&D department.
1975: Ekrem Düzgün founded the company to make agricultural machinery.
1996–1999: Investments in the Konya 3rd Organized Industrial Zone shifted the focus to plastic pipes.
2001–2008: The site grew to 100,000 m² of open and 30,000 m² of closed area.
Today the company is managed by Ziya Düzgün and Kemal Düzgün.
U-PVC deep well pipes are rigid PVC (polyvinyl chloride) pipes used inside a water well. There are two groups: casing and screen pipes that line the borehole, and column pipes that carry water from the pump to the surface.
They stop the borehole from collapsing and let clean water in. Düzgünler Plastik produces them for 100, 300 and 500 metre depths, plain and slotted, to TS 11794 and under an ISO 9001:2015 quality system.
A column pipe, also called a drop pipe, carries the weight of the pump and delivers water to the surface. The DCP series has four models: Medium Plus, Standard Plus, Heavy and Super Heavy.
A square thread, a coupling and an "O" ring at the end of the thread keep sand and silt out of the joint.
Short answer: U-PVC deep well pipes suit corrosive water and quick installation. Steel is considered for projects with very high mechanical loads.

Buyers in Spain and Morocco should confirm customs paperwork and water conditions first.
Türkiye and the EU are in a customs union for industrial goods, and shipments move with an A.TR movement certificate. Confirm the details with your customs agent in Spain.
Import duties for Morocco depend on current rules; confirm them with your freight forwarder before fixing the budget.
Many plastic pipe manufacturers focus on one product group. Düzgünler Plastik produces four more alongside its deep well range.
U-PVC pressure clean water pipes: 4–16 Atm, three socket types.
HDPE PE100 pipes: TS EN 12201-2; coils and straight lengths.
Latched sprinkler pipes: 5, 6, 8 and 10 Atü; TS EN 12201-3.
Corrugated pipes: SN4 and SN8 classes for drainage and cable protection.
Plastic pipe manufacturers need four details to propose the right series.
Well depth and the level where the pump will sit
Borehole diameter and the pipe diameter you need
Pump power and expected flow rate
Whether the water is sandy or saline
For product details, contact Düzgünler Plastik or visit the column pipe and deep well pipe category pages.
Start with the product standard and the ISO 9001 certificate, then ask for the test report for your batch.
Düzgünler Plastik produces casing pipes for 100, 300 and 500 metre depths. The right series depends on the depth of the well and the ground conditions.
A casing pipe lines the borehole and stays in place. A column pipe carries water from the pump to the surface and can be removed for maintenance.
Not always. The two materials need different production lines, so plastic pipe manufacturers often specialise in one. Düzgünler Plastik produces both.
In the Konya 3rd Organized Industrial Zone in Türkiye.
U-PVC is rigid and used inside wells and pressure lines. HDPE is flexible and can be supplied in coils.
The slots let water enter the well while keeping most sand and gravel outside.
It depends on pump depth and weight. Deeper, heavier installations use thicker-walled models such as Heavy and Super Heavy; confirm with the manufacturer's technical table.
