U-PVC Column Pipes

U-PVC Column Pipes: 4 Models From Türkiye's First Manufacturer

U-PVC column pipes are plastic pipes that carry water from a submersible pump up to the surface while holding the pump suspended in the well. The first company in Türkiye to produce plastic column pipes for submersible pumps is Düzgünler Plastik, founded in Konya in 1975.

What Is a Column Pipe and What Does It Do?

A column pipe, also called a drop pipe, connects to the outlet of a submersible pump inside a borewell and carries water to the surface.

The column pipe also carries load. The weight of the pump, motor, cable and the water column inside the pipe is transferred through this line to the well head. That is why choosing the right column pipe affects both water delivery and pump safety.

How Do U-PVC Column Pipes Work?

The system is made of pipe sections joined one after another from the well head downward. It works in this order:

1. The submersible pump is placed below the water level in the well.

2. The first pipe section is connected to the pump outlet.

3. The next pipes are joined at their square-threaded ends with couplers.

4. An O-ring at the end of each thread keeps sand and silt out of the joint.

5. Water rises through the pipe and reaches the installation at the well head.

The square thread makes it easy to assemble and disassemble the line at any depth.

Who Made the First Plastic Column Pipe in Türkiye?

The first company to produce plastic column pipes for submersible pumps in Türkiye is Düzgünler Plastik. Founded in 1975 by Ekrem Düzgün as an agricultural machinery maker, it moved into plastic pipe in 1996–1999. Today it is led by his sons, Ziya Düzgün and Kemal Düzgün.

• 1975: Founded, agricultural machinery production

• 1986: Steel pipe and automotive spare-parts production (1,100 m²)

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

• 1996–1999: Shift to plastic pipe production (25,000 m² open + 8,000 m² closed area)

• 2001–2008: 100,000 m² open + 30,000 m² closed production area

The company designs its own production machinery in its in-house R&D department. This keeps process control in its own hands.

Which U-PVC Column Pipes Models Does Düzgünler Plastik Offer?

Düzgünler Plastik manufactures U-PVC column pipes in four models for different load and depth needs. Every model has externally square-threaded male ends, a coupler connection and an O-ring. Production follows the ISO 9001 quality management system.

U-PVC Column Pipe vs Galvanized Steel Pipe: Which Is Better?

Plastic (U-PVC) and galvanized steel are the two most compared options. The choice depends on the water quality and the load the line will carry.

Pros and Cons of U-PVC Column Pipe

• Pro: U-PVC column pipes do not rust or change the taste or colour of the water.

• Pro: Light weight makes transport and installation easier.

• Pro: Square threads allow fast assembly and removal.

• Con: The model must be matched correctly to pump weight and depth.

Pros and Cons of Galvanized Steel Pipe

• Pro: High mechanical strength.

• Con: The zinc coating wears over time; rust appears in mineral-rich or aggressive water.

• Con: Its weight means installation and pump pulling need more equipment.

How Do You Choose the Best Column Pipe for a Borewell?

Choosing U-PVC column pipes starts with your pump and well data. Check these points:

• Setting depth: How deep the pump hangs in the well decides the model.

• Total load: Include the weight of the pump, motor, cable and water column.

• Pipe size: Match the pump outlet size (for example, 2 inch or 3 inch).

• Water quality: In sandy water, O-ring joints reduce thread wear.

• Documents: Ask for the manufacturer's quality management system and test records.

What Affects Column Pipe Price?

Column pipe price depends on pipe size, model (wall thickness), total length and order quantity. The difference between a 2 inch and a 4 inch column pipe price mostly comes from these factors. For a current price list, the best route is to request a quote with your depth and pump details.

Frequently Asked Questions - FAQ

Which column pipe fits a submersible pump?

Choose U-PVC column pipes that match the pump outlet size and can carry the total load of the pump and water column. DCP Medium Plus or Standard Plus suit lighter loads; DCP Heavy or Super Heavy suit deep and heavy applications.

Do PVC column pipes rust?

No. U-PVC column pipes are not metal, so they do not rust, a clear advantage over steel in aggressive water.

Is a column pipe the same as a borehole pipe?

No. A column pipe carries the pump and delivers water to the surface. A borehole (deep well) pipe lines the well wall to stop it from collapsing.

What does the O-ring on a column pipe do?

The O-ring keeps sand and silt out of the threaded joint. This keeps the seal tight and reduces loosening.

Is Düzgünler Plastik a column pipe manufacturer in Europe?

Düzgünler Plastik manufactures in Konya, Türkiye, and exports U-PVC column pipes to buyers abroad. For model and export details, contact the company directly.

People Also Ask - PAA

How deep can a column pipe be used?

Usable depth depends on the chosen model and total load, so select the model using your pump and setting depth data.

Can I install a column pipe myself?

The square-thread system makes assembly easier, but lowering a pump into a well needs lifting equipment and an experienced crew.

Why choose plastic pipe for a deep well submersible pump?

Plastic pipe is light, does not rust and does not affect water quality.
