Polyethylene is a sturdy and flexible material which must be handled with care. Pipes must not be dragged over the ground and rough surfaces. Polyethylene pipes are stored under a roof or in the open air, owing to high resistance to UV radiation and temperatures between -30 º C and +60 ºC.
The pipes are laid in the ground, inside trenches of a varying depth, depending on the type of the pipe and the ground, in accordance with the project designer’s specifications. When laid in soil, the depth of the trench ranges between 0.8 m and 1.2 m, depending on the configuration of the ground and the pipe diameter.
Connection of a pipeline is by the means of flexible or fixed connections.
- Flexible joints are connections with fittings, fasteners and flanges.
- Fixed joints are performed using butt welding or electro-fusion welding.
Our company uses modern, attested equipment and certified welders for butt welding of water pipes.
Installation of pipelines is performed in accordance with Standard SRPS EN 805.
The lowest temperature for outdoor installation is + 5°C.
Following the installation, the pipeline is tested using the procedure defined by the designer, in accordance with SRPS EN 805, point 11.
The PE fitting and PE pipes are made using the same material, which enables a highly secure and efficient jointing. The standard groups of products of pre-fabricated fittings include: fastener, elbow, straight and V joints, as well as reducing joints. Tailor-made element designed in accordance with the customers’ requirements are also supplied. Once completed, every pipeline must undergo a pressure test, in order to secure the complete tightness of the pipes, connector, fittings and other components.
