Düzgünler Plastik: Half a Century of Plastic Pipe Manufacturer Since 1975

Düzgünler Plastik is a Konya-based plastic pipe manufacturer founded in 1975 by Ekrem Düzgün and run today by his sons Ziya and Kemal Düzgün. The company supplies column pipes, deep-well (drilling) pipes, HDPE PE100 pipes, pressure clean-water pipes, latched sprinkler pipes and corrugated pipes for infrastructure, drinking-water and agricultural-irrigation projects.

How Did Düzgünler Plastik's Manufacturing Journey Begin?

Düzgünler Plastik's manufacturing experience goes back to 1975, when it started producing agricultural machinery. Over the years the company specialised in several fields before reaching its present focus on plastic pipe.

• 1975: Founded under Ekrem Düzgün, producing agricultural machinery.

• 1986: Steel pipe and automotive spare-part production in Konya 1st OIZ (1,100 m²).

• 1993: Automotive and machine gear production (2,400 m²).

• 1996–1999: Shift to plastic pipe and accessory production in Konya 3rd OIZ (25,000 m² open / 8,000 m² covered).

• 2001, 2005, 2008: Further investment reaching 100,000 m² open and 30,000 m² covered area.

Düzgünler Plastik is the first company in Türkiye to produce submersible-pump U-PVC column pipes. In this way it combines 51 years of manufacturing heritage since 1975 with roughly three decades of specialisation in plastic pipe.

Which Pipe Solutions Does Düzgünler Plastik Make?

Düzgünler Plastik offers a broad range for different sectors. The main categories are:

U-PVC Column Pipes

Used in submersible-pump and deep-well systems, the column pipes come in DCP Medium Plus, Standard Plus, Heavy and Super Heavy models. A square-thread system and “O” ring provide secure, leak-proof joints regardless of depth.

U-PVC Deep-Well (Drilling) Pipes

Made in 100, 300 and 500 metre depth options, the drilling pipes come in plain and slotted (screen) types. They are produced under TS 11794 and ISO 9001:2015 and resist corrosion and chemical wear.

HDPE PE100 Pipes

For drinking-water and irrigation lines, the HDPE PE100 pipes are offered in coil and straight lengths. They are produced under TS EN 12201-2 (equivalent to ISO 4427-2) and ISO 9001:2015, standing out for high pressure and chemical resistance.

Pressure Clean-Water Pipes

Produced with a 4–16 Atm pressure rating, the clean-water pipes include push-fit socket, solvent-weld socket and gooseneck types. They resist UV rays and chemicals.

Latched Sprinkler Pipes

For agricultural irrigation, the latched sprinkler pipes come in 5, 6, 8 and 10 Atü options and comply with TS EN 12201-3. The latch-lock system gives fast, leak-proof connection.

Corrugated Pipes

Made from HDPE for waste water, rainwater drainage and cable protection, the corrugated pipes come in SN4 and SN8 ring-stiffness classes. Their sealed structure speeds installation and flexes with ground movement.

What Makes Düzgünler Plastik Stand Out?

• In-house R&D: it designs and builds the machinery on its production line itself.

• A sector first: it states it was the first in Turkey to make submersible-pump U-PVC column pipes.

• Certified production: ISO 9001:2015 on the drilling and HDPE PE100 pipe lines.

• Large capacity: 100,000 m² open and 30,000 m² covered area in Konya 3rd OIZ.

• Wide range: from column pipes to corrugated pipes for infrastructure, water and irrigation.

U-PVC vs. HDPE PE100 — Which Pipe for Which Job?

In short: rigid U-PVC pipes lead in column, drilling and clean-water lines, while flexible HDPE PE100 pipes lead in pressure drinking-water and irrigation lines. The table compares the two.

Frequently Asked Questions - FAQ

When was Düzgünler Plastik founded?

Düzgünler Plastik was founded in 1975 under Ekrem Düzgün. Starting from agricultural machinery, it focused on plastic pipe production from the mid-1990s.

Which pipes does Düzgünler Plastik make?

It makes column, drilling, HDPE PE100, pressure clean-water, latched sprinkler and corrugated pipes. These serve infrastructure, drinking-water and agricultural-irrigation projects.

Where does Düzgünler Plastik manufacture?

Production takes place in Konya 3rd Organized Industrial Zone. The facilities cover 100,000 m² open and 30,000 m² closed area.

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

A column pipe carries the submersible pump inside the well and conveys water to the surface. A drilling (casing) pipe supports the borehole wall, prevents collapse and lets water enter the well.

What is an HDPE PE100 pipe?

HDPE PE100 is a pressure pipe made from high-density polyethylene. It is preferred in drinking-water and irrigation lines for its high pressure and chemical resistance.

People Also Ask - PAA

What is a column pipe?

A column pipe suspends the submersible pump in deep wells and delivers the pumped water to the surface. It is joined section by section with threaded couplers according to depth.

What is a drilling pipe?

A drilling pipe (well casing) supports the wall of a water well and prevents it from collapsing. Plain and slotted (screen) types are used.

What is a corrugated pipe?

A corrugated pipe is a double-wall HDPE pipe whose ribbed outer wall gives high ring stiffness. It is used in waste-water, drainage and cable-protection lines.

What is a PE 100 pipe?

PE 100 is a polyethylene material class with a minimum required strength (MRS) of 10 MPa. Pipes made from it suit high-pressure water and irrigation lines.
