Overview

The ONE PLUSTM PEXa cross-linked polyethylene pressure pipe is intended for the construction and repair of internal networks of cold, hot water supply, underfloor heating (operation classes 1, 2, 4 according to GOST 32415-2013).

It is allowed to use pipes for non-category technological pipelines transporting liquid media that are non-aggressive to the pipe material.

ONE PLUSTM PEXa pipe is made of Lutene-H XL1800 material manufactured by LG CHEM, LTD. Lutene-H XL1800 is an ideal material for extrusion of pipes for water supply, heating, underfloor heating, it has long-term cracking resistance, good mechanical characteristics.

The optimal combination of strength and flexibility, good "molecular memory", the ability to extinguish water shocks, withstand freeze-thaw cycles. The low cost of the ONE PLUSTM PEXa pipe is an excellent choice for installing a "warm floor", heating open areas and staircases, stadiums, swimming pools, heating the soil in greenhouses, hotbeds, winter gardens and greenhouses

Lutene-H XL1800 pipes have been tested by the Independent Testing Institute Bodycote Polymer.

Advantages of PEXa ONE PLUSTM pipes:

  • Not afraid of kinks and kinks. The molecular memory of the pipe material makes it easy to recover the shape when heated;
  • Absolute dielectric. The pipes do not conduct stray currents and static electricity;
  • The inner section of the pipe is not overgrown or silted up;
  • Ease of installation, low weight and ease of delivery of pipes in coils;
  • Large throughput due to low roughness of the inner layer of the pipe;
  • Versatility. Installation is carried out with press or compression fittings for metal-polymer pipes ONE PLUSTM.

The table uses the following designations:

Tslave   — operating temperature or combination of temperatures of the transported water, determined by the field of application;

Tmax   — time-limited maximum operating temperature;

Tавар — аварийная температура, возникающая в аварийных ситуациях при нарушении систем регулирования.

HOW TO USE THE TABLE

The maximum service life of the pipeline for each class of operation is determined by the total operating time of the pipeline at temperatures T slave, T max, T avar   and is 50 years. 

For example, for class 4, the calculation is as follows: 2.5 years (at 20°C) + 20 years (at 40°C) + 25 years (at 60°C) + 2.5 years (at 100°C) = 50 years
