Türkiye's Leading Plastic Pipe Manufacturers

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.

How do you evaluate plastic pipe manufacturers? 7 criteria

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.

1. Product standard: Which standard is the pipe made to? (For example TS 11794 or TS EN 12201.)

2. Quality management: Is there an ISO 9001 quality management certificate and a test record for your batch?

3. Production capacity: Can the plant supply your diameters and volumes without interruption?

4. R&D strength: Does the company develop its own machinery and tooling?

5. Product range: Can one supplier cover the well, the mains and the irrigation line?

6. Joint design: How do the thread, seal and coupling keep the connection tight?

7. Technical support: Do you receive data sheets, dimension tables and test reports in writing?

Why does Düzgünler Plastik stand out in U-PVC deep well pipes?

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.

How long has Düzgünler Plastik been manufacturing?

• 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.

What are U-PVC deep well pipes, and which products do they include?

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.

What do U-PVC casing and screen pipes do?

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.

What does a column pipe for a submersible pump do?

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.

How is the joint sealed?

A square thread, a coupling and an "O" ring at the end of the thread keep sand and silt out of the joint.

U-PVC deep well pipes vs steel pipes: which suits your borehole?

Short answer: U-PVC deep well pipes suit corrosive water and quick installation. Steel is considered for projects with very high mechanical loads.

What should buyers in Spain and Morocco check before ordering U-PVC deep well pipes?

Buyers in Spain and Morocco should confirm customs paperwork and water conditions first.

What should buyers in Spain confirm?

• 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.

What should buyers in Morocco confirm?

• Import duties for Morocco depend on current rules; confirm them with your freight forwarder before fixing the budget.

Which other pipes does Düzgünler Plastik produce?

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.

How do you request a quote for U-PVC deep well pipes?

Plastic pipe manufacturers need four details to propose the right series.

1. Well depth and the level where the pump will sit

2. Borehole diameter and the pipe diameter you need

3. Pump power and expected flow rate

4. Whether the water is sandy or saline

Frequently Asked Questions - FAQ

What should I check first when comparing plastic pipe manufacturers?

Start with the product standard and the ISO 9001 certificate, then ask for the test report for your batch.

How deep can U-PVC deep well pipes be installed?

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.

What is the difference between a column pipe and a casing pipe?

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.

Are PVC pipe manufacturers and polyethylene pipe manufacturers the same companies?

Not always. The two materials need different production lines, so plastic pipe manufacturers often specialise in one. Düzgünler Plastik produces both.

Where does Düzgünler Plastik manufacture its pipes?

In the Konya 3rd Organized Industrial Zone in Türkiye.

People Also Ask - PAA

What is the difference between U-PVC and HDPE pipes?

U-PVC is rigid and used inside wells and pressure lines. HDPE is flexible and can be supplied in coils.

What is a slotted PVC well screen used for?

The slots let water enter the well while keeping most sand and gravel outside.

Which column pipe model suits a deep borehole?

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.
