PEX-a / EVOH pipe for heating

A cross-linked polyethylene pressure pipe with a barrier (anti-diffusion) layer of ethylene vinyl alcohol (EVOH) is intended for the construction and repair of internal networks of cold, hot water supply and radiator heating of buildings

Overview

A cross-linked polyethylene pressure pipe with a barrier (anti-diffusion) layer of ethylene vinyl alcohol (EVOH) is intended for the construction and repair of internal networks of cold, hot water supply and radiator heating of buildings, including underfloor heating (operation classes 2, 4, 5 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 PLUS PEX / EVOH pipes consist of 3 layers:

  • inner polymer PEXa layer;
  • adhesive layer;
  • a barrier layer of a copolymer of ethylene and vinyl alcohol EVOH;

ONE PLUS PEXа / EVOH pipes are specially designed for use not only in hot and cold pressure water supply systems, but also in central heating systems, as they meet the requirements of SNiP 41-01-2003, which prescribes the use of polymer pipes with an oxygen permeability index of no more than 0.1 g / m3 per day (also the requirements of GOST 32415-2013, DIN 4726). Oxygen is corrosive to heating systems. Penetrating through the pipe wall, oxygen causes corrosion of the metal elements of the heating system (boilers, heat exchangers, valves, thermostats, etc.).

Application area

Scope of ONE PLUS PEXa / EVOH pipes 2, 4, 5, ХВ operating classes according to GOST 32415-2013:

  • Hot and cold water supply in residential, industrial and office buildings;
  • Radiator and underfloor heating systems (warm floors);
  • Water wall, radiator-free heating (“warm walls”);
  • Process pipelines and water treatment systems;
  • Heating of open areas and staircases, stadiums, swimming pools, etc .;
  • Heating the soil in greenhouses, hotbeds, winter gardens and greenhouses.

Installation


The main feature of the installation of ONE PLUS TM PEXa / EVOH polymer pipes is the use of fittings with a slip sleeve. Also, this system is called axial press-fit piping system. A distinctive feature of this system are:

  • the presence of a special brass sliding ring, which ensures the sealing of the connection;
  • the absence of any O-rings in the fittings, which undoubtedly increases the reliability of the system;
  • increased internal passage of fittings, in comparison with press and compression fittings for metal-polymer pipes of equal diameters;
  • extremely strong, reliable and durable connection;
  • installation is carried out with a special tool for axial pressing.

Installation steps

  1. Cut the pipe strictly at right angles;
  2. Put the sleeve on the pipe and move it away from the edge;
  3. With a special expander, expand the edge of the pipe where the fitting of the fitting will be inserted;
    1. ! The fitting cannot be inserted into an unexpanded pipe, because the diameter of the nipple of the fitting is larger than the inner diameter of the pipe.
  4. Insert the fitting into the expanded pipe;
  5. Press in with a special tool: push the sleeve onto the fitting up to the skirt on the fitting, avoiding distortions.
