Bergen PEX-a pipe with O2 barrier
BERGEN PEX-a are pipes with oxygen barrier for heating systems, sanitary water and secondary parts of public heating systems. They can also be used for cooling and material transport systems.
Description
Pipes are delivered in coils. Easy and ergonomic mounting is reflected in regular bending of 5x of pipe diameter, while benders are used for bending of 3.5x of pipe diameter.
Molecular orientation provides the hardness of tubes.
Due to a high level of flexibility and hardness, the product is extremely highly resistant to breaking, bending and other physical irregularities.
Possible cracks are not spreading rapidly.
Thermal resistance is reflected in the possibility of continuous operation at 70°C with a pressure of 6 bar, while short-term operations at -100°C and +110°C are also possible.
Due to low pressure and dripping, there is no risk of creating deposits.
Reduced wear level due to low friction resistance.
