Slotted pipes, as the name indicates, are pipes designed to have uniform slot openings that enable liquids to enter or discharge freely while effectively filtering out foreign and unneeded particles at the same time. These pipes are used for various applications such as oil and gas wells, tube wells, borewells, or in drainage pipes for delivering or collecting liquids.

Plastic slotted pipes perform well across several different industries. PVC and HDPE are both good materials for producing slotted pipes, and you can get the best high-quality pipes from Polyfab Plastic Industry LLC.

What Makes Polyfab Slotted Pipes Different?

Since 2005, we at Polyfab have been working with builders, architects, designers, government entities and more to provide outstanding construction materials and infrastructure solutions and help enhance quality of life in the UAE.

We use next-generation fabrication technology to manufacture durable, industry-compliant slotted pipes that meet our clients’ specific required dimensions. Made from premium-grade materials, our PVC and HDPE pipes have the structural strength and other optimal performance properties to meet industry standards and last several decades.

Here’s an overview of how slotted pipes are manufactured, what their key features are, and which industries and applications they are made for.

How Are Slotted Pipes Made?

Trusted slotted pipe channel suppliers in the UAE like Polyfab offer different fabrication methods that include carving grooves onto the surfaces of plastic pipes in widths and depths specific to a project’s requirements.

• Laser technology is one example of a method that ensures smooth and uniform creation of slots for slotted pipes.
• Using automatic slotting machines is another example. These work with a computerized Programmable Logic Controller (PLC) system that automates the process of cutting slots into the pipes. The control system is easy to operate and ensures topnotch accuracy and consistency.

High-quality slotting equipment should be able to accommodate the standard thickness and size of plastic pipe materials that are commonly used across different industries, as well as be able to demonstrate high production capacity. It is also an advantage to use slotted pipe manufacturing processes that allow a variety of cutting options which enable successful customizations for clients’ varying needs.

Slot Types/Profiles

Straight Slots

A straight slot is cut at a right angle. It has the same diameter inside and outside the pipe wall. These slots are cheaper to produce but are less effective when used in applications with sand.

Keystone Slots

Also called a tapered slot, a keystone slot is cut at a slight angle and is larger on the inside compared to the outside of the wall. This ensures that particles can pass through the slot without getting clogged. Keystone slots are more expensive to manufacture .

Common Types of Slot Patterns

• Line (Straight) – Slots are evenly placed in identical bands all around the pipe, forming straight lines
• Single Slot Staggered – The machine spaces bands of slots evenly around the pipe, and the slots in different bands are in alternating spots or offset against each other (not aligned)
• Gang (Multiple Staggered) – This has the same layout as the single slot staggered pattern, except that it creates two slots instead of one at each position, and comes in a staggered/offset pattern.
• Custom – This is made according to the client’s requirements.

Types of Distribution of Slots

• Parallel
• Crisscross
• Spiral

Plastic Base Materials Used for Slotted Pipes

PVC

Polyvinyl chloride or PVC pipes are durable, corrosion-resistant, and can withstand harsh, high-pressure conditions both aboveground and underground. They have a high flow capacity and good insulation properties.

PVC slotted pipes are excellent for drainage systems and are typically used for similar water supply management purposes such as plumbing and irrigation. They are also ideal for electrical cabling, mining wells, telecommunications, ducting and other applications.

HDPE

High-density polyethylene or HDPE pipes are made of thermoplastic polymer. Extremely tough, HDPE pipes also have non-conductivity properties and exhibit better resistance to chemicals, which means HDPE pipes can carry potable water and wastewater as well as chemicals or compressed gasses.

As a brief comparison between PVC and HDPE pipes:

• PVC pipes are strong and stiff, making them perfect for direct burial situations. They perform well in pressure, uniformity and hydrostatic tests.
• HDPE pipes, meanwhile, have a higher density and can withstand twice the pressure class as PVC. They are completely UV-resistant and can withstand higher temperatures (up to 80 degrees Celsius, which is why they can also function as fire fighting pipes). They are also softer and easier to bend, which means they have the flexibility that can prove critical in harsh conditions like rain or stress.

Features of PVC and HDPE Slotted Pipes

Polyfab manufactures slotted pipes in a well-integrated setup using premium-grade materials to ensure structural integrity.

Here are the key features of our PVC and HDPE slotted pipes:

• Available sizes are from 110mm to 400mm
• Come with full threaded or slip joints
• Fast and easy to install
• Lightweight and convenient to transport
• Exceptional mechanical strength and stress resistance
• Highly resistant to corrosion, abrasion and temperatures
• Non-toxic and sterile
• Outstanding flow performance thanks to smooth inside walls
• Superior surface appearance (no slits or fur) owing to precise machining
• Low risk of damage such as cracking, breaking and deformation
• Longer service life
• Customizable to suit clients’ specific diameters

Common Slotted Pipe Applications

Conveying Liquids

Slotted pipes ensure a high flow rate for allowing fluids like water, solutions and oil to pass easily.

Drainage/Dewatering and Irrigation

The uniform and consistent sizes and distribution of slots enable the successful expelling of water from farmlands while also preventing soil erosion.

Tubewells, Borewells and Aquifer Water Storage and Recovery

A tubewell is a kind of underground water well that uses pipes driven into a subsurface aquifer to extract groundwater. A borewell is similar, except it accesses deeper water resources that are more challenging to reach. Slotted pipes create a barrier that prevents impurities such as sand, soil and other debris from entering the water.

Mine, Oil and Other Industrial Wells

Slotted pipes help block impurities in different types of wells that are crucial components of agricultural and industrial fields.

Environmental

Slotted pipes are instrumental in the operation of various environmental protection projects including collecting and monitoring groundwater, managing geothermal systems, collecting waste infiltration fluids and more.

Domestic Properties

Keeping external drainage flowing smoothly is reinforced by slotted pipes in residential areas, helping to prevent damage to houses and their plumbing systems.

Designed to Perform, Manufactured to Last

From drainage to agricultural and industrial projects and systems, slotted pipes serve the necessary function of allowing the proper flow of liquids and filtering of harmful debris.
