HDPE Pipe Manufacturers

What’s HDPE pipe?

HDPE pipe, also called high density polyethylene or polyethylene pipe, is made of HDPE granule material. Firstly, it was made by PE63 material, and then PE80 material. Till now, most of HDPE pipe is produced by a improved generation, called PE100 material.

Here in Sunplast, we provide HDPE pipes that are made by PE100 material & PE80 material only.

What’s the meaning of PE63, PE80 & PE100? What’s the difference between the HDPE pipes that are made of PE63, PE80 & PE100?

The designations PE63, PE80 & PE100 are based on the long-term strength of the respective materials, known as the minimum required strength (MRS) in accordance with ISO 12162.

The designations are:

The main differences between the HDPE pipe that are made PE63, PE80 & PE100 are the density, viscous stress and quasi-static stress. The HDPE pipe made by PE100 material has a higher strain hardening modulus than PE80 & PE63, and offers better viscous stress and quasi-static stress, which allows thinner pipe wall for the same pressure rating.  

For example: for the same diameter HDPE pipe & same wall thick, such as:DN110×10.00mm in SDR11, for PE100 material its pressure rating is PN16 bars, while PN12.5 bars for PE80 & PN10 for PE63.

 

What’s SDR & PN means in HDPE pipes?

SDR, also called Standard Dimension Ratio, refers to he ratio of the outer diameter to the thickness of the HDPE pipe, which is SDR=OD/WT.

PN refers to nominal pressure of HDPE pipe, referring to the normal pressure for water transportation at 20℃.

 

For the HDPE pipe made by PE80 & PE100, at the same SDR rating, the PN is different:

Material/SDR	SDR9	SDR11	SDR13.6	SDR17	SDR21	SDR26
PE80	PN16 bars	PN12.5 bars	PN10 bars	PN8 bars	PN6 bars	PN5 bars
PE100	PN20 bars	PN16 bars	PN12.5 bars	PN10 bars	PN8 bars	PN6 bars

What diameters of HDPE pipe can Sunplast provide? And what’s the applicants of Sunplast HDPE pipe?

Now, SUNPLAST HDPE pipe has been widely used in various fields,such as water plumbing & sewerage system, gas distribution, slurry transfer lines, rural irrigation, fire system supply lines, electrical and communications conduit.,etc, but mainly:

※ HDPE water pipe

HDPE pipe be used for water is the most popular. HDPE pipe is a green material that can deliver drinkable water, it has been widely used for municipal water supply/drainage systems, fire work systems, sea water desalination works..etc.

※ HDPE gas pipe

HDPE pipe is also widely used for outdoor gas distribution for municipal works.

※ HDPE dredge pipe

HDPE dredge pipe, which is light weight,abrasion performance & smooth surface, has been a ideal replacement of steel pipe. Assembled with flanges at both ends, HDPE dredge pipe is easy for dredge work at the site

※ HDPE irrigation pipe

HDPE pipe has been more & more popular used for irrigation systems for agriculture. The flexibility allows HDPE irrigation pipe can be coiled in 100/200m length, by using PP compression fittings, it greatly save the installation costs & times. Moreover, due to superior UV resistance performance, HDPE pipe has becomed the most eco. & ideal choice for irrigation systems.

 

What colors available for HDPE pipe?

SUNPLAST HDPE pipe for drinking water is regular in black colors with blue strips or blue colors.

The HDPE pipe for outdoor gas distribution is in yellow color or black color with yellow strips.

 

The HDPE pipe for the other usages can be determined between buyer & supplier, but recommend in black color.

 

What’s the super advantages of HDPE pipe by comparison of the other traditional piping?

The HDPE pipe has become a primary choice of replacement of galvanized steel pipe or other plastic pipe (like PVC pipe) that are used for water, because it reputes many incomparable advantages:

※ Non-Toxic: HDPE pipe made by PE100 or PE80 material only, no heavy metal additives, pollution free, suitable for drinkable water supply.  

※ Corrosion Resistance: HDPE is a kind of insert material, which made HDPE pipe to be free affected by acid, alkali and salt. Thanks to corrosion resistance, HDPE pipe can also be serviced for the delivery of salty seawater.  

※ High flow capacity: HDPE pipe’s smooth interior walls and low abrasion resistance result low flow resistance and high flow capacity.  

※ Excellent Flexibility: Small diameter DN20-63mm HDPE pipe can be supplied in coils, from which fewer fittings be needed, and lower installation costs.  

※ Excellent UV resistance: While production of HDPE pipe, a 2%~2.5% of carbon black will be added, this makes HDPE pipe (black color) can be exposed under the sunshine for long time working.  

※ Easy & reliable installation: Due to light weight, HDPE pipe is easy to transport & handle friendly.  

The HDPE pipe uses hot-melt fusion technology by using a special welding machine. The jointing is much stronger than HDPE pipe itself.  

※ Long service time: HDPE pipe can be working for more than 50 years under proper use.  

※ Use trenchless installation: The HDPE pipe can be installed by trenchless technology, which will greatly save the installation costs & time.  

※ Various fittings available: There various HDPE pipe fittings for options: HDPE socket fusion fittings, HDPE butt fusion fittings, HDPE electrofusion fittings & PP compression fittings.  

 

How to connect HDPE pipes & HDPE pipe fittings?

Luckily, HDPE is a kind of thermal-melt material, and the HDPE pipe & HDPE pipe fittings can be welded by hot-melt technology, which is the most reliable welding method. Once the hot-melt welding is finished, as long as it passes the Hydrostatic pressure test, the whole piping systems will be 100% a leak-free.

 

Sunplast HDPE pipes & HDPE pipe fittings are mainly connected by 3 hot-melt welding methods:

※ HDPE pipe socket fusion technology

The socket fusion is used to join the HDPE pipe & HDPE pipe fitting from DN20 to DN110 mm of diameter. It is performed by heating the external surface of the hdpe pipe and the internal surface of the HDPE pipe fitting up to achieving the fusion of the material, and then it is inserted one in another while the material is still hot.

※ HDPE pipe butt fusion technology

The Butt Fusion is the most important and widely used method of connection for HDPE pipes larger than 110 mm. It is a method of jointing pipe ends by way of heating and cooling under pressure, resulting in pipe joints as strong as the pipe itself.

The HDPE butt fusion requests the HDPE pipes & fittings have the same outer diameter, and the tolerance of wall thickness of both shall be no exceed 10%, in order to assure the best welding results.

※ HDPE pipe electrofusion technology

The Electrofusion is a simple method of joining HDPE pipes & HDPE pipe fittings in circumstances where butt fusion is not practicable, such as where valves, elbows, and tees must be added.

The HDPE electrofusion fittings have small copper wires coiled around the inside surface of both ends. By using HDPE electrofusion machine, the electric current is then run through those wires in turn melting the HDPE on the inside of the HDPE electrofusion fitting and the outside of the HDPE pipe.

 

The other regular connection method for HDPE pipe is by mechanical connection: the both connected pipe (or fittings) ends be welded with HDPE flange adaptors, using steel bolts/nuts to fix both ends together. The HDPE pipes & fittings be connected by mechanical connection can be assembled or disassembled easily, which is normally for dredge work or mining works.

 

PP Compression fittings are also very regular used for small HDPE pipes with diameter dn20-110mm, which is another mechanical connection. The HDPE pipes connected by PP compression fittings are normally for irrigation systems.

How do you connect HDPE pipes to the other pipe, such as PVC pipe, steel pipe?

When HDPE pipe be connected to the PVC pipe or steel pipe, since they are not made by HDPE material, so hot-melt welding is not available for connection.

 

The only possible method to connect HDPE pipe to PVC pipe is by mechanical connection, using flanges or use transition fittings,like female or male thread adaptor fittings.
