Polyethylene is a typical type of thermoplastic plastic. Polyethylene pipes /PE/ are widely used for domestic sewage systems. However, it is not recommended to lay them in soils with a risk of contamination with chemical substances. Polyethylene has low reactivity, which makes it possible for poisons to penetrate into the water. Polyethylene pipes are characterized by very good physicochemical properties, which explains their increasingly widespread use in the construction of water supply and sewage networks, fire protection installations, treatment plants, irrigation systems, drainage systems, etc.
POLYETHYLENE PIPES /PE/ - ADVANTAGES, CHARACTERISTICS AND MAINTENANCE
The main advantages of polyethylene pipes are usually the low relative weight compared to steel or cast iron pipes, easy and quick installation, as well as the possibility of quick and easy repairs in case of accidents. They are resistant to the aggressive effects of a wide range of chemical compounds, bacteria, fungi and others. Among their advantages are the low resistance of the pipe walls due to the high degree of smoothness, which does not allow the accumulation of deposits, the fact that they are not susceptible to corrosion, elasticity and long service life. They are characterized by high resistance to impact, low temperatures, bursting, etc.
Polyethylene pipes, due to their physical, chemical and hydraulic properties, are considered very suitable for the construction of sewage systems for domestic and industrial wastewater. Due to the elasticity of the material, polyethylene pipes are also used for sewage systems passing through unstable terrain, where the use of pipes made of harder materials is not suitable due to the risk of breakage as a result of landslides. The facilitated installation of polyethylene pipes due to their flexibility, durability and lightness also leads to economic benefits.
Depending on the density, polyethylene is divided into low, medium and high density polyethylene . For sewage systems, it is recommended to use mainly high density polyethylene pipes, whose life is the longest - up to 50 years. They are distinguished by high strength even at low temperatures. In case of damage due to external factors, such as excavation work, construction machinery, etc., under the influence of internal pressure, polyethylene pipes do not split into long cracks, and breakage remains limited. They are characterized by a long service life and easy maintenance.
POLYETHYLENE PIPES AND FITTINGS - APPLICATION, INSTALLATION AND LAYING METHOD
Polyethylene pipes are widely used for water supply and sewage. However, it is worth considering that when transporting drinking water, they should not be laid in soils contaminated with chemicals related to polyethylene. In such a case, there is a risk that these contaminants will pass through the walls of the pipe and contaminate the water.
Polyethylene pipes are suitable for underground and above-ground laying, as well as for the construction of underwater networks.
The flexibility of polyethylene pipes allows for variations in direction without the need for special connectors. It is important to note that air vents should be provided at the highest points of the pipeline.
When laying pipes underground, it is recommended that they be laid at a depth of at least 100 cm from the surface. Regarding the laying bed, experts recommend paying special attention to the trench in which the pipes will be laid. The pipes are not allowed to come into contact with hard objects such as stones and others. It is recommended that the pipes are not laid directly on the bottom of the trench, but on a bed of sand or other fine material. Among the requirements is that the bed for laying the pipe should have a completely flat support surface and ensure uniform distribution of loads along the entire length of the pipeline. It is important that the bed is not too hard and provides the pipe with good and evenly distributed support.
The pipes are filled with fine material on top, preferably sand. It is best to compact them by hand.
Mechanical fittings are used to mechanically connect pipes, and they can be plastic or metal. The fittings themselves can be reusable or permanently installed.
In the product group you can find a wide variety of PE pipes with different parameters. We also have all the necessary fittings from the same material, as well as taps and even small details such as clamps and plugs.
