Beside the standard pipes and fittings, customers usually need a non standard pipes (flanged pipes) to satisfy some special requirements, this short pieces could be manufactured according to the special designs that may be requested by the customer.

Four types of flanges are provided, corresponding to the nominal pressure PN 10, PN 16, PN 25 and PN 40, and these can be connected to pipes in a fixed or removable way. The later arrangement has the advantage of making casting mounting and PN change easier.

- For short lengths flanged pipes, it could be manufactured with integral flanges or welded flanges.

- For long lengths flanged pipes, it should be manufactured with screwed flanges or with welded flanges (welding neck flanges or slip on flanges for welding.

The wall thickness e has been calculated as a function of the nominal size DN using the linear formula e = K (0.5 + 0.001 DN)

Where:
K = 12 and 14 for pipes with integral flanges;
K = 10 and 12 for pipes with screwed flanges;
K = 9 for pipes with welded flanges (welding neck
flanges or slip-on flanges or welding).

As for spigot and socket pipes, the wall thickness for small diameter pipes is calculated using a complementary formula;

e = 5.8 + 0.003 DN (with a minimum value of 6 mm)

Which is applicable to DN 40 to DN 200 for pipes of class K = 9 and DN 40 to DN 125 for pipes of class K = 10.

Polyethylene is recognized internationally product for gas and water distribution. Polyetylene is flexible, leaktight and highly resistant to chemical attack. PE 80 and PE 100 pipes fittings are suitable for use where ground
movement is expected, where corrosive soils are present and where long ducts and flexibility in bending are required.

Scope and Field of Application

Although principally developed for conveying water
and gas, polyethylene pipes have many other applications.
HDPE pipes become widely adopted in a variety
of piping systems which are successfully used for many

applications some of which are:
1- Potable water supply and distribution pipelines
2- Drainage and sewerage
3- Irrigation systems
4- Fire fighting networks
5- Chilled water
6- Electrical conduits
7- Gas distribution
8- Industrial and chemical applications

General Properties

The properties of PE have been described as
- Light and easy to handle
- Impact resistant and long lasting
- Corrosion resistance
- Strong
- Conveniently Flexible
- Tough
- Resists cracking
- Low frictional resistance
- Resistance to chemical attack

Strength
The strength of a pipeline may beconsidered as the ability to withstand stress in the pipe material under internal pressure over a period of time. The design stress considered within the water industry is taken to be a life expectancy in excess of 50 years.

Toughness
In practice it is recognized that PE is a tough material. The many years of successful installation of PE pipe in the water and gas applications added confidence of this recognition.

Flexibility
The inherent flexibility and recovery of PE enables the pipeline to absorb impact loads, vibration and stress caused by soil or ground movement which implies that PE have useful fatigue characteristics where loading are present,
( pumping and heavy traffic loading conditions).

The property of flexibility enables PE pipelines to be countered to difficult road layouts or rapid changes of direction.
