All you need to know about HDPE Pipe


About HDPE Pipe: It is no secret that there are currently various types of pipe available for building and other sectors. We need it to make waterways in a building and in the countryside to make housing power lines. And among the various types on the market, pipes made of high density polyethylene are one of the most sought after.

Get to Know More about HDPE Pipe, Its Materials and Advantages

Referred to a special product because it has a food grade standard, this type of pipe is used for various needs. One of them is to support the distribution of pressurized clean water. In addition, it is also often used for fiber optic pipe installations by telecommunications companies, channels for chemicals and gas, and so on. Then, what exactly does this type of pipe product mean?

What is HDPE Pipe?

Considering the definition, HDPE pipes are a type of pressurized plastic pipe made of high-quality plastic raw materials. The name of this product itself refers to the raw material used to make it, namely high density polyethylene. Because it is made of polyethylene which is then abbreviated as PE, this plastic pipe is often referred to PE as well.

Polyethylene, Raw Materials of PE Pipe

Then, what is polyethylene itself which is the raw material for this pipe product? Polyethylene is basically a thermoplastic that is widely used for plastic bag products. This material is a type of polymer produced from petroleum materials. Besides being used for the manufacture of HDPE pipe, this material is also often used in various productions of household appliances and so on.

The Advantages of This Pipe Type

There are several things that make polyethylene referred to high-quality materials. One of them is because the material is not easily damaged. Not only that, this material is also known to be safe and has a food grade standard. That’s why it becomes a pipe material that is safe for eating and drinking equipment. Here is complete information about the advantages of pipes made of polyethylene.

# 1 Durable

When it comes to the durability, this type of pipe has many features in dealing with the conditions that occur around it. PE pipe is said to be able to last up to 50 years and more noted that the product is used in normal use. And here are the features of the PE pipes which make it able to survive for a long time.

·         Resistant to chemicals

One of the things that makes this type of HDPE pipe can last for decades is because it can withstand various types of chemicals. With its quality, PE can be used to drain various types of materials ranging from clean water to chemicals. More interestingly, it can withstand these various chemicals for a lot of time.

·         Resistant to UV light

Not only is it resistant to chemicals, hoses or pipes made of high density polyethylene can also withstand UV rays. Because of its ability to withstand UV light, this HDPE pipes is not fragile and is able to last for decades. Therefore the use of these pipes has also become increasingly diverse in the community.

·         Resistant to rust

Besides not easily broken and damaged, HDPE pipes are pipes that are also not easily corroded. This certainly cannot be separated from the quality of PE materials that do not easily contain rust. Because of this advantage, there is no doubt that this type of PE pipe is widely used to connect clean water and even drinking water that we can consume safely.

·         Resistant to various weather conditions

Another thing that makes this HDPE product last longer is because it is able to survive in various weather conditions. This product is suitable in various regions even in the most extreme weather conditions. Besides being resistant to temperatures of up to 60° C, this product is also resistant to low temperatures. It makes the pipes can be applied in four-climate and tropical countries.

#2 Strong Connection System

Polyethylene also has a very strong and safe connection system. In this case, if we want to connect HDPE pipes with something else, we don’t need to be afraid if there is a leakage. For example is when we want to connect it to a clean water line to the kitchen. We don’t need to be afraid of leaking because the connection is safe.

#3 Light and has a smooth surface

Furthermore, this PE pipe is also known to be lighter than an iron pipe. Compared to the weight of an iron pipe, the pipe with PE material is about 1/6 lighter. In addition, this product also has a smoother inner surface. This very smooth surface makes HDPE pipe is suitable for connecting drains because they can avoid leaks.

#4 Flexible

Another advantage possessed by products made of PE is this one is extremely flexible. This product has a degree of flexibility at a 25x outer diameter of the pipe. This advantage makes the installation process of the product not requiring a lot of accessories especially for turns. In addition, because it is flexible, no need to fear that this product can break easily during installation.

#5 Does Not Contain Poison and Environmentally Friendly

Then, pipes made of high density polyethylene also do not contain poisons so they are very safe to use for all needs. This is inseparable from the character of PE which has a strong bond between molecules that are not easily damaged and pollute the flow of water in it. In addition, this material is also easily recycled so it is more environmentally friendly.

#6 Connection System Varies

The connection system of HDPE pipe is not only strong, but also varies greatly. There are various methods that can be done to connect this product including mechanical joints and welded fusion. For welded fusion or melting methods, for example, it can be done with electro fusion and butt fusion. In this case the method of electro fusion can be done without machines and adhesives.

Discover the Types of HDPE Pipes

After getting to know more about what PE pipes and their advantages are, of course we should not miss information regarding any type of pipe made with this polyethylene or PE material. Just like other similar products, those who sell HDPE pipe will also offer these pipes in various types. And here are the variants that are usually offered on the market.

Based On Its Use

Well, the pipe product made of polyethylene can indeed be used for various needs ranging from clean water lines to cable protectors. In this case, pipe products are often offered with adjustments so that they can be used for certain needs desired by clients. And here are some variants of PE products that are often offered based on their use.

·         For Construction of Clean Water Channels

Because of its superiority and quality, PE is highly recommended for making clean water lines as described above. For the manufacture of clean water lines, it seems impossible if we are offered a product type of subduct pipe because this one type is usually intended for telecommunication cables. Generally for clean water, the types offered are usually those that have a dominant black color with a size of half an inch to 24 inches.

·         For the Construction of Pressurized Gas Channels

It’s different if we want to buy PE for the manufacture of pressurized gas channels. If for clean water the product offered is predominantly black, for pressurized gas lines the product usually has a dominant yellow color. In addition to pipes made of polyethylene materials, products made of MDPE material are often used as an alternative to building pressurized gas channels too.

·         For Cable Sheets or Wires

For the needs of fibre optic cable protectors, polyethylene pipe products are also often considered. As a material that is resistant to bump, strong and flexible makes pipes with PE material very suitable to protect cable lines that are usually planted underground. Moreover, currently it is offered in roll form with a choice of up to 100 meters per roll which makes application easier.

Based on Product Packaging

It should be noted that product made from high density polyethylene is usually packaged in two different forms, namely coil or roll and straight. For example for fiber optic pipe, usually offered in roll form. Both of them certainly have different functions in terms of helping the installation process, connection system and also mobilization according to existing needs. Let’s discuss one by one.

·         HDPE Straight Pipes

Usually this type of product is available in a length of six meters. However, the length of the product can still be adjusted to our needs. For example, a length of 5.8 or 11.8 per straight pipe is chosen regarding shipping need using containers. For the needs of water pipes, for example, rods with a length of 6 or 12 meters can be chosen.

These straight pipes are usually available in a variety of sizes ranging from 1-1/2 inches to 24 inches. Even some brands on the market today provide a larger size up to 30 inches. For the connection procedure itself, PE pipes with rod packaging are usually connected with the butt fusion method using a welding machine.

·         HDPE Roll Pipes

Similar to straight pipes, type of HDPE pipe in roll packaging is also available in various lengths. Currently there is a length of 50 meters to hundreds of meters for each roll or coil. However, the limitations of large rolls make this type of pipe available in sizes which are not more than or equal to 4 inches in diameter.

Based on Pressure Needs

Next, this type of pipe can also be distinguished based on press requirements. In this case, this product comes with a variety of pressure requirements which are generally represented by the term Pressure Nominal (PN). PN itself refers to the level of the product strength against pressure. Based on SNI (Indonesian National Standard), here are some kinds of HDPE pipes according to PN requirements.

·         Type PN-6.3 and PN-8

PN-6.3 is the type with lowest pressure. On the market, we can find PN-6.3 products in various sizes ranging from 3 inches to 24 inches. Because this one product has a very thin wall thickness, we will not find products of this type in roll form. For type PN-8, it is currently available in several types of sizes ranging from 2-1/2 inches to 24 inches.

·         Type PN-10

HDPE pipe on PN-10 type is the most commonly used for making pressurized clean water lines nowadays. This product can be pressed with a pressure level of 10 kg/cm² or 10 bar making it suitable for building branching channels and main channels. This type is available with a choice of diameters ranging from 1-1/2 inches to 24 inches.

·         Type PN-12,5

PN-12.5 is very suitable for the construction of clean water lines with a rather high pressure. As the name implies, this type has a pressure level of up to 12.5 kg/cm² or 12.5 bar. Unlike subduct for fibre optic cable, this pipe is very suitable for the distribution of water channels such as mining waterways, public facilities to households.

·         Type PN-16

PN-16 is a pipe product made of polyethylene which has the greatest pressure. Unlike other types, products of this type can generally be found in all types of diameter sizes. We can find it with sizes of 1/2 inch to 24 inches. In addition, this type is also available in both straight and roll forms.

Those are various types of pipe which are currently offered by various well-known pipe brands. Given the number of similar brands that sell HDPE pipe, it is not impossible if we are confused when having to choose a brand with the best products. But, you don’t need to worry because currently there is Denya that is ready to provide the best product for you.

How to join HDPE Pipe with all kind of pipe material using universal joint


Universal Joint

There are so many way to join the HDPE pipe we can find out on the internet. But when we discuss in more detail about how to do joint with other kind of pipe material, we found that very seldom people discuss about it. As our client frequently ask question, herewith we discuss about universal joint,the way to join HDPE pipe with almost all kind of pipe material.

Commonly there are so many kind to join the HDPE pipe, but since today we founf that only two popular way to do HDPE pipe to other pipe material join. Other pipe material here means kind of PVC pipe, PPR pipe, Steel pipe, Galvanize pipe and some more.

Here is the two popular kind of universal joint:

  • Stub Flange joint
  • Thread joint


Stubflange joint

denya hdpe stubflange

Stubflange joint means flange to flange joint. Using stub end as the flange holder then bolt and nut to lock the joint. Kind of simple joint and very strong joint. Provide stub flange to each end of the pipe. Remember to insert a gasket or rubber packing between the joint before tighten the bolt and nut.

Required: HDPE welding machine, HDPE Stub end, Flange (any material).

This universal joint generally use to join the larger HDPE pipe.(Diameter 160mm up diameter).


Note that there is a one more universal joint called Flange adaptor but sadly this product only cover up to pipe 110mm diameter and below.

HDPE male adaptor – PVC female adaptor

Thread joint is a kind of universal joint which more easier to joint than stubflange joint. Using the PP compression adaptor fitting (both male and female thread adaptor),  We can easily join the HDPE pipe with other pipe material.

Required: Strap belt, PP compression fitting (male or female thread adaptor), PTFE seal tape

People usually use this universal joint for pipe with diameter 110mm and below.



Good news there is an advantage for both of the universal joint. We can easily unlock the joint and re-join it many time.
