PPR Pipe Extrusion Line: The Ultimate Importers Guide in 2018

With the rise in urbanization, there has been a demand for cheaper, durable, and greener products.

This demand has lead to the widespread adoption of PPR pipes in China and around the world.

Plastic pipes are gradually replacing steel pipes, concrete pipes and galvanized pipes.

In fact, the China Plastic Pipe Industry Association hints that the usage of PPR pipes is increasing year by year.

In this guide, you will learn all about PPR; from the basics to how to manufacture them.
Read this through, and you became an expert on the subject.

So, let’s start:

Chapter 1: What are PPR pipes?

Figure 1: PPR pipes with different colors

1.1 What is the definition of PPR?

They are solid walled pipes manufactured using polypropylene random copolymer.

We use them in hot or cold plumbing systems mostly in residential areas.

How do we connect PPR pipes?

To connect PPR pipes together or to their fittings, we must first heat them.

This is called fusion welding.

And you use a PPR Pipe Welding Machine.

Here is a video that will help you understand how PPR pipes are welded.

You may notice that the biggest benefit of PPR is that we don’t need glue to join them together unlike PVC pipes.

The joins created by fusion welding are also strong and water-tight.

In this aspect, PPR pipes are more economical.

1.2.1 Raw material for PPR Pipe

I told you earlier that we use polypropylene random copolymer to make PPR pipes.
But, what is it?

It is a thermoplastic resin made by the polymerization of polypropylene with ethylene.

It has desirable properties such as a broad range of melting points and high melt flow rate.

This makes PP random copolymer thermoplastic very suitable for injection molding and extrusion.

We use injection molding to make PPR fittings and extrusion process for manufacturing PPR pipes.

Figure 2: Image showing PP RP 100 granules

You can get PP-Random copolymer in form granules.

We recommend PP PR 100 resin granules.

1.2.2 Does PP RP 100 have any advantages?

Yes.

It is easy to die.

You will only buy a TiO2 master batch pigment available in different colors such as green, white, black, red etc.

PP RP 100 also has good impact resistance, excellent processing performance, and density of about 0.9g/cm3.

It is among the lightest thermoplastic resins.

1.3 PPR Pipe Fittings

Figure 3: Various types of PPR fittings

PPR pipe fittings have many uses:

Like connecting PPR pipes together, join PPR to galvanized metal pipes, attaching taps among other uses.

The fitting’s size has to correspond to the pipe’s size.

For example, if a pipe has an outside diameter of 25mm, we need a socket fitting with a diameter of 25mm.

To make it easy for the customer to match the pipe to the fittings, the size details are milled on fittings.

Next, I will show you how some fittings are used:

Okay, PPR pipes are sold in standard lengths of 4 meters.

If we want to join two PPR pipes together, we weld them into a socket.

Figure 4: PPR Socket/Coupling

To join three PPR pipe sections, we can use a tee.

We may need to create a 90-degree angle between two PPR sections, thus we use an elbow.

Figure 5: PPR elbow

Some fittings such as male and female tees, are made using plastic and metal such as brass, galvanized steel, or copper.

Figure 6: Female PPR Tee

1.4 PPR Pipe size table

In PPR Pipe size table, you can see the various diameters of PPR pipes.

We also classify PPR pipes according to the pressure they can handle.

You will notice that as we move from PN1.25 to PN2.5, the diameter increases as the pressure rating increases.

	PN 1.25	PN 1.6	PN 2	PN 2.5
Outside Diameter	Wall Thickness (mm)	Wall Thickness (mm)	Wall Thickness (mm)	Wall Thickness (mm)
20 mm	1.9	2.3	2.8	3.4
25 mm	2.3	2.8	3.5	4.2
32 mm	3.0	3.6	4.4	5.4
40 mm	3.7	4.5	5.5	6.7
50 mm	4.6	5.6	6.9	8.4
63 mm	5.8	7.1	8.7	10.5
75 mm	6.9	8.4	10.3	12.5
90 mm	8.2	10.1	12.3	15.0
110 mm	10	12.1	15.1	18.3
160 mm	14.6	17.9	21.9	26.6

 

1.5 Does the PPR pipe strength decay by temperature?

This is a commonly asked question, and I will take time to address it here.

Yes…heat can distort plastic pipes made of PVC, ABC, and PE.

However, PPR pipes can withstand high temperatures making them suitable to carry hot water.

For instance, PPR pipes without pressure have an operating temperature of 100^o C.

Vicat softening of PPR pipes occurs at 152.2^oC, which is higher than that for ABS, PVC, and PE pipes.

Conclusion

In this chapter, you have gained some basic knowledge of PPR pipes.

Next, I will show you how you can manufacture PPR pipes, the equipment you need, how it works and more!

So, let’s go…

Chapter 2: The PPR pipe Manufacturing Process

Figure 7: PPR manufacturing line

In a very basic explanation of the PPR pipe manufacturing process:

We take the thermoplastic material (in form of granules), heat it until it becomes a molten liquid, pass it through a mold in shape of a pipe, and cool until it becomes a solid pipe.

In summary, heating is done in the extruder.

Shaping is done in the mold.

Cooling takes place in the vacuum calibration tank and cooling tank.

Are you ready to learn this process in detail?

Let’s start by looking at:

2.1 The working process of PPR pipe machinery

PP PR Resin Granules + Color Master-batch → Vacuum Auto Loader→ Hopper Dryer → Single Screw Extruder → Color/Marking Line Extruder → Spiral Mould → Vacuum Calibration Tank → Spray Cooling Tank → Printer → Cutter → Stacker

2.2 How the Equipment in a PPR Pipe Production Plant Works

Let’s take a tour of the PPR pipe factory.

2.2.1 Vacuum Loader

The first equipment we encounter in a PPR Pipe manufacturing line is a vacuum auto-loader that’s also called a vacuum feeder.

Figure 8: Vacuum Loader

You can tell by its name that it does some loading or feeding.

Actually, it feeds the raw materials (PP PR resin and color masterbatch into the hopper dryer).

2.2.2 What is a hopper dryer?

Figure 9: Hopper Drier showing main parts

Also called a hot air dryer, it resembles a tank mounted on top of the extruder.

Besides holding the PP PR resin pellets, it also drys them.

See, the granules or pellets can collect moisture on their surface.

So how does drying occur?

Good question…

Our hopper dryer has a heating mechanism consisting of a blower, heater, heating cylinder, and electrical control box.

The blower draws in ambient air from the surroundings.

A heater heats the air.

Then, the heated air is blown through the heating cylinder into the bottom of the hopper tank.

As the hot dry air, passes over the pellets, moisture is absorbed.
You can adjust the temperature using the electric control box.

There is an opening called a feed throat at the bottom of the funnel-shaped hopper.

Once the raw materials are dry, it opens allowing the raw materials to descend onto the turning screw by gravitation force.

2.2.3 The single screw extruder

Figure 10: Extruder showing the screen changer

With the extrusion process,we can create PPR pipes with a fixed cross-sectional profile.

Extrusion happens in the extruder.

I’ll briefly explain how it works…

The extruder has a barrel, which is hollow and circular.

It houses a screw.

If it is a single screw, we call it a single screw extruder.

There is a decrease of the barrel’s diameter down the extruder.

I will tell you its significance later.

But now, the raw materials will fall on the screw’s feed section.

The screw has three main sections:

• Feed zone
• Compression/transition/plasticizing zone
• Metering zone

After the feed zone receives the raw materials from the hopper’s feed throat, it pushes it forward.

For this to happen, the raw materials must adhere/cling on the barrel and slip on the screw.

Maintaining the right temperature in the feed zone is very critical.

Failure to which will cause the raw materials to just move around the barrel and not forward.

What about the compression zone?

In the compression zone, the channel depth is less than in the feed zone.

This forces the screw to press the raw materials against the barrel with increased forced (compression).

Melting of the granules to molten polymer also occurs in the plasticizing zone.

So does homogenization or mixing of the melt.

Finally, we have the metering zone.

It facilitates the delivery of the polymer matrix to the die.

2.2.4 Color/Marking Line Extruder
Before we talk about the plastic pipe marking line extruder, I want to show you a picture of a PPR pipe with a marked line.

Figure 11: PPR pipe showing red line

Why do we mark our PPR pipes?

It is essential to keep track of each pipe, know where it’s going, and what it is carrying.

We use color and lettering to tell what each pipe contains.

If we don’t color our pipes, it going to confuse and even pose a danger to the user.

Markings for PPR pipes

PPR pipes with red strips, signal that they are for hot water.

And those with green stripes, channel cold water.

In the PPR pipe extrusion plant, we use a plastic pipe color marking line small/mini extruder for marking.

Figure 12: Mini Extruder/Coloring extruder for PPR pipes

Why do we call it mini or small?

It’s smaller than the single screw main extruder.

But don’t be mistaken, the mini extruder has all the main parts of an extruder including the screw, barrel, motor, gearbox, and electrical parts such as an inverter, contactor, relay, temperature sensor & breaker.

2.2.5 Co-extrusion spiral die

Preliminary shaping of molten polymer into a PPR pipe starts at the die.

The die sets the pipe’s approximate inner and outside diameters.

You will notice that I have said “approximate inner and outside diameters.”

Yes…the die gives the PPR pipe its roughcut dimensions.

To get international accepted dimensions of the tube, you will need to calibrate or fine-tune the PPR pipe using the vacuum calibration tank.

We will talk about calibration later, but first, let’s see what the co-extrusion spiral die does:

Figure 13:  Co-extrusion spiral die connected to the main and mini extruder

When we have two extruders (main extruder and color extruder), there are two melt streams.

To combine them, we use a co-extrusion die.

I will not get into the technical details regarding dies, but just note that there are two types of dies for pipes and tubes; cross-head dies and spider dies.

You can learn more about dies from this resource (Pipe and Tubing Dies).

2.2.6 Vacuum calibration tank

In the vacuum calibration tank, you cool the hot PPR pipe that has left the extruder, at the same time, sizing it to the desired size.

Sizing starts at the entrance of the calibration tank.

Here, you will find a calibration sleeve (also called calibration or sizing tool).

Figure 14: Vacuum calibration tank showing control panel and sizing sleeve

Its diameter corresponding to the dimensions of your final pipe e.g. Ø20 calibration, Ø25 calibration.

You can buy different sizing sleeves and fit them on the vacuum tank.

We use sleeves made of special metal alloys.

They facilitate excellent heat exchange and generate minimal friction allowing the pipe to slide through easily.

As you shop for a PPR pipe making machine, be on the lookout for the specified range of diameter the vacuum water tank can accept for instance, 16mm to 2000mm

At the entrance, the upstream end of the tank, there is water draining onto a tray.

The cooling waters facilitates cooling as the pipe enters the tank.

So, what is the working mechanism inside the vacuum calibration tank?

Figure 15: Vacuum calibration tank side view

A vacuum inside the tank results in positive pressure being created inside the PPR pipe.

This will force the outside of the pipe against the inner race of the sizing sleeve.

Thus, the outside diameter is set this way.

We can also control the wall thickness of the PPR pipe in the calibration tank.

You can do this by varying the  PPR pipe haul-off /take-off/pulling speed relative to the exit speed of the PPR extrudate from the die.

If the take-off speed is higher than extrudate’s exit rate, the thickness of the pipe will decrease.

Figure 16: Control panel for Vacuum tank

There are a set of rollers inside the vacuum tank to guide the PPR pipe.

These rollers may be placed above the pipe to pass the pipe underwater, or below the pipe to support it as it’s spray cooled.

2.2.7 Spray Cooling Tank

Figure 17: Spray Cooling Tank

After calibration and cooling in the vacuum calibration tank, we still need to cool the pipe further before it’s cut, stacked or wound up by a winder.

But why?

Cooling helps prevent the pipe’s deformation as other machines handled it.

So what’s inside the cooling tank?

There are spray sprinklers or nozzles along the length of the tank.

Other mechanical parts of the spray tank include water reservoirs, drip pans, heat exchanger, turbo filters, and vacuum pump.

Spray tanks can have two or three chambers to increase the cooling capacity.

And are typically 6 to 9 meters in length.

But you can order a custom-made cooling tank with a length of up to 12 meters depending on your processing needs.

So, how does cooling of the pipe occur?

Cold water droplets, chilled to about 45 °F, strike the hot surface of the PPR pipe.

They rapidly absorb heat from the pipe.

Since the spray tank has a closed circuit water system, the warm water is simply filtered, cooled and recycled.

Filtering the water will help you prevent the spray nozzles from clogging.

2.2.8 Printer

You will need to print the company’s name, logo, pipe’s diameter, logo etc.

To do this, there are two types of printers you can use to mark your PPR pipes:

• Pipe inkjet printer
• Laser printer

The inkjet printer is a low-tech mechanical device with an ink tank, and word wheel embossed with the information you want to print.

It’s less expensive than the laser printer. However, it suffers some drawbacks such as high ink consumption and maintenance.

The laser marking machine uses a special kind of powdered ink to print characters on the PPR pipe.

It uses advanced technology with some laser printers equipped with touch screens and automatic meters.

Thus the printing done by the laser printer tends to be cleaner, less messy or dirty and highly legible.

Unlike an inkjet printer where the characters and fonts embossed permanently on the blocks, you can easily change the text and font on the laser printer.

The markings are also wear-resistance and difficult to remove.

Thus, we recommend a laser printer to our customers.

2.2.9 Haul-off or Puller

 

Figure 18: Puller

We use the puller to draw the pipe from the corrugator are permanently and to guide it to the cutter accurately.

The puller consists of caterpillar tracks made of rubber or other special materials that enhance the grip on the pipe and reduce slippage.

Our puller has two tracks, but some have pullers have three or four tracks.

Figure  19 Tracks inside the puller

You can lower the caterpillar track on the pipe to increase its hold.

A motor drives the tracks, and a high-quality frequency converter sets the speed.

There are also speed indicators fitted on the puller.

2.2.10 Planetary Cutter

Figure 20: Cutter adjacent to the puller

PPR pipes, e.g. from 20mm to 160mm can be cut into standard lengths of 4 meters and 5.8 m.

In that case, you will need a no-dust planetary cutting machine.

To minimize sawdust inside the pipe a circular saw performs the initial cut, and a saw blade finishes off the cutting.

Figure 21: Planetary cutting device

The cuts are smooth and uniform, and there is no need for further grinding or processing.

Other advantages of our cutter include:

It adopts advanced technology, such as a PLC control that controls all the mechanical devices such as the moving cylinder, clamping cylinder, etc.

This ensures high accuracy and efficiency.

The cutter is also low noise, and suitable for high-speed production.

2.2.11 Stacker

Figure 22: Stacker

You can employ personnel to off-load the PPR pipes from the line and stack them.

Alternatively, we have included an automatic stacker in our PPR processing line to enhance its performance & automation.

By do this, our customers save time and labor costs in the long run since they require few employees, about two, to manage the processing line.

You can also wind the PPR pipe into a coil like in the picture below.
Some PPR pipe coils lengths include 100 m, 150m, 200m, etc.

Figure 23: PPR pipe coil

To wind the pipe, you will need the automatic PPR pipe winder.

It’s fitted with a torque motor and the winding speed is determined by the pipe extrusion speed.

You can also choose between a single or double spool winder.

Typically, double and single winders are suitable for tubes with diameters of 16 to 63 mm. And a single winder for pipes with diameters of 63-110 mm.

Conclusion

In this chapter, you have seen the different machines that make up a PPR pipe extruding line.

Now join me in the chapter, as I introduce you to the wonderful properties of PPR pipes.
You stand to learn how your customers might use PPR tubing and fittings. Let’s go:

Chapter 3: Properties, Advantages, and Applications of PPR Pipes

Figure 24: White PPR pipes with blue marking lines

Whichever country you reside in, chances are, there is a market for PPR pipes & fittings, and a gap waiting to be filled by your PPR pipe manufacturing company.

And after satisfying the local market, you can export your PPR pipes to other markets.

Most PPR pipes that you sell will end up in internal plumbing systems of upcoming residential and commercial structures.

Similarly, PPR pipes are gradually replacing PE and PVC pipes in water distribution networks.

Here are some PPR pipe properties that without doubt make them widely used:

3.1 PPR Pipe mechanical properties

1.        Light weight with good impact strength, surface resistance and mechanical abrasion.

2.        Good range of working temperatures of up to 95⁰C.

3.        High chemical corrosion resistance, which ensures that PPR pipes last longer.

4.        The pipe’s smooth inner surface offers low flow resistance and prevents sediments from depositing. In addition, PPR pipes don’t scale, unlike metal pipes.

5. PPR pipes are not very susceptible to pressure loss or head loss since their inner surface is smooth. On the other hand, galvanized pipes and copper pipes suffer from more head loss than plastic pipes.

6.        They have good thermal insulation and low thermal conductivity, which prevents heat transmission in or to the surroundings.

7.        They have a low elastic modulus, which makes PPR pipes are very flexible.

8. They are widely used in developed countries.
9. They are food grade safe. And they don’t contain plasticizers that may be added during the manufacture of PVC pipes to enhance their flexibility. What’s more, their internal structure is mostly made up of hydrogen and carbon with no halogens.

10.   The useful life of PPR pipes for indoor plumbing is estimated to be 50 years, provided the user has correctly selected the appropriate pressure series for their system.

11.    They are easy to lay, and welding creates a firm, homogeneous joint, that is very resilient and leak proof.

12. You can recycle PPR pipes after use making them environmentally friendly.

3.2 Applications of PPR Pipes and Fittings

You may have noticed that PPR pipes have different wall thickness for the same outside diameter.

For instance, a 20 mm PPR pipe has a variety of wall thickness such as 1.9mm (PN 1.25), 2.3mm (PN 1.6) and so on.

Based on their wall thickness and outside diameters, plastic pipes are classified into different series numbers such as S5 and nominal pressure grades.

A PPR pipe with a nominal pressure (PN) of 2.5, basically means that it has a maximum working pressure of 2.5 bar for water at 20^oC and a service life of 50 years.

It’s appropriate to select the right pressure series to ensure long operational life.

Next, let’s talk about the uses of PPR pipes which include:

1. Transport of clean drinking water in water distribution networks.
2. In hot and cold water pipe systems for offices, schools, hospitals, residential buildings, high rise buildings etc.
3. In industries to transport water and other chemicals. In the video below, you can see PPR pipes installed in an industry:

 https://youtu.be/EfYmtMCYIr0

4. Used in production systems for drugs, beverages etc.
5. Conveying compressed air in air plants.
6. Used in the collection of rainwater.
7. In internal heating system for flooring, wall heating, and radiating systems.

Conclusion

In this chapter, we have tackled the properties and uses of PPR pipes. In the coming chapter, I will show you how you can find the best price for the PPR production line.

• Chapter 4: How to find the best PPR Pipe Making Machine Price

Figure 25: PPR pipe production line price

Generally, the price for the PPR production line can range anywhere from $20,000 to $150,000.

The quality of the parts used to make the line is one factor that causes the vast fluctuation in the price.

If high-quality brand parts from reputed manufacturers are used, the cost of the line may be higher.

The dimensions of the pipe you want to manufacture and the speed of the line will also cause deviations in the price.

For instance, if you require a high-speed line, we will need to supply an extruder with a higher-output.

4.1 Ask for the best price

The best thing to do in order to get the lowest price possible is to reach out to the PPR pipe machine supplier and ask for a discount and the lowest price they can offer.

Usually, when you purchase multiple sets same machine such as the five or more, you will get a substantial discount.

4.2 Choose safe products

Please ensure that you’re dealing with a credible supplier. For example, check to see if the company has a certification from the SGS in China.

This is not enough because some suppliers may make promises and fail to deliver the product up to your specifications after you sign the contract.

So go an extra step and ensure that the supplier has an ISO certification and that the products have passed benchmark tests.

It’s also smart to ask about past orders they have fulfilled and present customers.

You can also visit the factory to confirm its location and nature of the business. For instance, if the company is a trading company or an actual machine manufacturer.
