What is Oxygen-barrier pipes?

In today’s home decoration, many customers will choose to equip Oxygen-barrier floor heating pipes in their new house.

Floor heating system is much advanced in uniform heat dissipation and home design field.

But many friends haven’t heard of the Oxygen-barrier floor heating pipes till now. So here, we’d like to share some basic application and advantages of this EVOH(Oxygen-barrier) pipe.

Why we need Oxygen-barrier pipes?

We should talk from the harmful of floor heating system by oxygen.

1. It’s well known that the aging of the plastic and metal is the result of various effect such as light, tothermal, oxygen, fatigued etc.

As far as concerning the light, the life of plastics will be extened 10-20 years; without oxygen, the life of plastics and metals will be extended by 10-20 years.

If there’s a large amount of oxygen in the hot water flowing in the heating al product such as boiler, valve, heat exchangers will gradually be oxidized. Server corrission will occur and the heat transfer effiency will be gradually decreased.

2. When oxygen enters into water system, it breeds microorganisms. And the microorganism’s life is week and dying fast. More and more microbial corpses will turn into biological slime. The formation of this substance will form a thermal insulation layer in the tube, so that heat cannot be emitted, so that the indoor heat load is reduced and the temperature is not increased. Second: more and more biological slime is formed. Finally the pipe is blocked and no heating result. When the hot water temperature up than 40 °c, it will also accelerate the thermal oxygen aging of the pipe due to the penetration of oxygen into the plastic pipe body because of the high temperature.

How is oxygen-barrier(EVOH) pipe so popular in the global market?

Due to the several advantages of EVOH-PERT/PEX pipes.

In Europe, a large of oxygen-barrier pipes are used in hot-water systems(heating, air-conditioning, floor-heating etc). In floor-heating field, America, Europe and Australia are mandtory required to use oxygen-impermeable heating plastic pipes. It can block the penetration of oxygen into the piping system. Thereby preventing the metal parts from corroding and rusting. Greatly extending the service life of metal parts, such as metal valves, switches, boilers and manifolds in the heating system. At the same time, bacteria which lying on oxygen can not breed. While protecting the pipes, it increases the life of wall-hung boiler heating system.

Which kind of Oxygen-barrier pipes are better?

Floor heating pipes have 3 layers or 5 layers structure. Normally, 5 layers oxygen-barrier effects are better than 3 layers, and more reliable. The 5 layers co-extruded oxygen-barrier pipes are connected with the fittings with only the outest plastic layer., which ensuring the safety of connection.

KAIDE machiney are expertise in this Oxygen-barrier pipe making machine for over 10 years.

Main features of the pipe machine

Production speed is 35m/min, based on the pipe diameter: 20*2.0mm

This production sed to produce PE-Xb-Glue-EVOH-Glue-PE-Xb 5 layers pipes. The middle EVOH layer can effectively prevent the oxygen from entering pipe system, protecting pipes for rapid corrosion, reducing the possibility of microbial growth and ensuring the pipe inner side is cleanly and freshly.

It's combined with 3 extruders, composite pipe die head, vacuum tank, water flume, hauler, automatic coiler etc.

1. 5 layers extruder for each layer

This Oxygen-barrier PE-Xb tubing machine adopts advanced extrusion technology with several extruders and co-extrusion die head mould, ensuring the pipes each layer is boned firmly with precise pipe size. Special designed screw and barrel for EVOH resin, can suit the high melt pressure of oxygen -barrier resign.

2.Co-extrusion Die head mould

Special self-developed and long period improved die head has been vertified to have many advantages. For example, easy operating, each layer thickness can adjust freely and even, high precision for pipe size and thickness.

The popular pipe size:16-32mm

3.Calibrating and cooling system

​

4. Haul-off machine for EVOH floor heating pipes

5. Automatic EVOH/PE-Xb pipes

Remark:This also be used to produce 3 or 5 layes PE-RT/EVOH pipes. Some more details haven't been listed out, if you have interest, pls with us directly
