Polyethylene is a polymer obtained from the polymerization of ethane in the presence of catalysts under specific conditions of pressure and temperature. Depending on the properties of the polymerization process different types of polyethylene are obtained which are used for the extrusion of pipes.

Thanks to technical developments, the materials obtained from this process have improved their characteristics; such as PE80 and PE100 which are named as 2nd and 3rd generation PE.

Main applications

  • Water distribution (transport of drinkable water)

  • Sewer systems, drains, industrial fluid discharge and buried drainpipes

  • Pipelines and underwater pipelines

  • Irrigation and drainage

  • Gas distribution

  • Relining (new piping, restoration of damaged pipelines)

  • Transportation of suspended solids

  • Protection of cables, electrical and phone wires, and optical fibers.


Nets and water distribution 
(Transportation of drinkable water and food)

The system fully complies with the European Community requirements (July 1980) and recommendations of WHO, Geneva 1984. UNIT 217, ISO 4427 (1996), UNIT-ISO 4427 (1998) & ISO 8795 (1990).

Gas Distribution

Polyethylene pipes are used in Gas distribution networks for low and medium pressures up to 4 bars. PEMD yellow pipes or black pipes with yellow stripes are used in order to fulfill the signposting requirements for gas pipelines. (ISO 4437, 1997)

Pipeslines and underwater pipelines

One of the great advantages of our pipes is that they are suitable for connections across rivers, channels and lagoons, what can not be done with other products. Sub aquatic connections, buried or over the bed are used to carry drinkable water with pressure, to carry sewage, or for other applications such as protecting Electrical and Phone wires.

Sewer systems, drains, industrial fluid discharge, and buried drainpipes

They are fit for underground applications for sewer systems or draining with no internal service pressure, because they can resist the external load of ground weight and heavy traffic.
To determinate the pipe’s size the following conditions and parameters must be taken into account: ditch’s depth, ground’s density, installation method (compressed), ground’s rigidity (deformation) Plastic deformation ( 50 years, long lifespan), and resistance to heavy traffic whenever it is required.
We highly recommend the use of SDR 33 (or less) pipes , because deformation will always be less than the specified value 6% (recommended for these uses) for a long lasting durability (50 years).

Irrigation and drainage

They can be used for spraying watering, dripping watering and micro spraying watering. An appropriate system of regulation and control can measure out the water and fertilizers.

(New piping, restoration of damaged pipelines)  

Polyethylene pipes are suitable for relining, a technique which consists in introducing another pipe in a damaged pipeline section to restore it or to reinforce its mechanical strength.
This method is used for sewage and drinkable water pipelines, gas conducts, and buried aqueducts.

Transportation of suspended solids
(Mining and dredging)

The pipes resist corrosive and abrasive erosion. They are highly used in hydraulic transportation of solids from sand and crushed stone deposits, in hydraulic and mechanical mining of carbon and minerals

These pipes have the advantage of being manufactured in coils of any lenght. This is one of the reasons why their use becomes popular for the protection of phone and electrical connections underground, or under water.


Additional advantages

PE pipes compared with PVC pipes

  • Lightweight, they are easy to transport and manipulate.

  • More flexibility: they adapt better to ground’s conditions.

  • High resistance to impact.

  • Improved resistance to Ultraviolet rays, they can be installed on the ground, exposed to direct sunlight.

  • Does not get corroded chemically nor biologically. They are highly resistant to chemical industrial fluids.

  • Does not allow the formation of crust, thanks to their smooth internal surfaces .

  • Excellent Hydraulic characteristics, due to an absolute smoothness of 0.02 mm (smooth internal surfaces). They have a “C” factor (Hazen-Williams coefficient) of 150 .

  • Does not pollute drinkable water, does not transmit smell, colour, or flavor. Ideal for carrying drinkable water.

  • Does not pollute the environment, their welded joints do not admit escapes or introduction of toxic.

  • Can be used with other types of pipelines already installed due to the wide range of adaptor fittings in existence.c

  • Can be joined by thermofusion or electrofusion

  • The service can be interrupted by the squeeze off technique, allowing a safe repairing.

  • Can be installed by trench systems

  • Can be used under water, adapting to the bed of seas and rivers.

  • It is the only material that allows relining for reinforcement or repairing.

  • It is not an electricity conductor, and a bad heat conductor.

  • Supply and packing: Up to 110 mm diameter they are packed in coils of different lengths.

  • More economic and safer installations are obtained with less possibilities of leakage due to the few number of joints needed.

  • Long Lifespan (minimum 50 years) guaranteed by the security coefficients used in the design of the pipes


New Polyethylene Classification

Different types of Polyethylene are classified by their properties, which are determined by their density, molecular weight and molecular weight distribution. Nowadays Polyethylenes are classified regarding their mechanical resistance and, specially, resistance to long time internal pressure (minimum 50 years).a) Density allows Polyethylene to be classified as Low (ldpe), Medium (MDPE), and High Density (HDPE). When polyethylene has high density it is more rigid and less flexible.b) Molecular weight determines fluency rate, so the higher the molecular weight is, the lower the fluency rate, and consequently the higher the mechanical resistance it has.c) Molecular weight distribution is divided in wide or narrow due to the fact that the polymer’s macro molecules are not all the same length, and are statistically distributed as per a Gaussian curve. The Gaussian’s curve width influences the mechanical characteristics, and the polymer’s capacity to be processed.

Pipe’s Marks







Plastiducto’s polyethylene pipes are easily installed due to compression fittings (Ref 1), Electrofusion (Ref 2) or Thermofusion (Ref 3). There are also transition fittings that join these pipes with others of different materials using weldable plates or elastomerics joints (Ref 4), enlarging the usage of these pipes.


There is a complete range of these accesories, from 16 mm to 160 mm. of diamete

Reference 1)
Quick joints or Compression fittings 
It is a simple system, safe and quickly to assemble. The water tightness is obtained by the compression of a rubber ring against the fitting and the adjustment of an external nut. This does not allow the pipe to be removed..


There is a complete range of electrical fusion fittings up to 400 mm of diameter.

Reference 2)
Electrical fusion
It consists of welding the pipe with a fitting that has a resistance inside through which a low voltage current circulates when connected to the welding machine, originating the amount of heat (Joule effect)  required to obtain the welding.


This technique is used from 110 mm to 1200 mm of diameter

Reference 3)
Butt Welding
It consists of heating both ends of the pipes or fittings to be joined by using a heating plate and applying a welding pressure during a specified time (Installation DVS 2207-German)
Our Technical Department can perform the welding or provide technical advice indicating the parameters to use in this kind of welding.
