What is the difference between floor heating oxygen resistance pipe and non oxygen resistance?

Floor heating oxygen resistance pipe, that is, floor heating pipe, the difference between floor heating pipe and pert pipe is as follows:

1. The difference between floor heating pipes and pert pipes.

1. The ingredients are different.

Floor heating pipes: The composition of floor heating pipes is polypropylene.

Polybutylene, polyethylene, etc.

Pert tubes: The composition of pert tubes is polyethylene and octene.

2. The production method is different.

Underfloor heating pipes: Underfloor heating pipes are made of peroxide.

It is made by cross-linking, silane cross-linking, electron beam cross-linking, and azo cross-linking.

Pert tubes: Pert tubes are made of medium density polyethylene and octene copolymerization.

3. The role is different.

Floor heating pipes: Floor heating pipes are mainly used for pipes that are circulating flow carriers of low temperature hot water.

Pert Pipe: Pert pipe is mainly used for non-cross-linked polyethylene pipe for hot water.

2. Advantages of floor heating pipes and pert pipes.

The floor heating pipe has good low temperature impact resistance, and the pipe is not easy to be damaged by impact during winter construction, which increases the flexibility of construction arrangement; Floor heating pipes can be used without polluting the environment; The thermal conductivity of the floor heating pipe is good, which is very suitable for underfloor heating.

Pert tubes have good flexibility.

reduce construction costs; Good chemical corrosion resistance, no rust, long service life; Light weight, good flexibility, can be supplied in coils; When the pipe is bent, the stress in the bent part can be relaxed quickly, and there will be no "rebound" phenomenon, which is convenient for construction and operation.

Oxygen molecules entering the heating system through the walls of plastic pipes can cause the following hazards:

1. Corrosion of metal components in the system.

2. With free calcium, magnesium and sodium ions in water.

reaction, the production of limescale.

3. There is the possibility of the presence of organic matter and microorganisms in aerobics, and it is easy to produce algae. Algae adhere to the pipe wall, which will thicken the pipe diameter, reduce the water flow, and increase the heating time, increase the gas cost, and reduce the comfort.

The average pert tube has a service temperature of 60 °C and a limit temperature of 90°, and the structure is not particularly stable. The outlet temperature of underfloor heating water is 55 65 with radiators.

The outlet temperature is 75 85, so pert tubes are not recommended.

Oxygen barrier pipes prevent oxygen molecules from penetrating into the water of the heating system through the plastic pipe layer, thus avoiding the rapid corrosion of metal parts in the equipment.

In ordinary non-oxygen-blocking floor heating pipes, oxygen will penetrate into the pipes and form some dirt, which is what we call dirt in the floor heating pipes.

Dirt in underfloor heating pipes.

After the floor heating heating molecular movement speed accelerates, oxygen and other substances have a chemical reaction, molecular chain decomposition, resulting in aging, the permeability of the general polyethylene pipe in milligrams liters or more, so in this case, the oxygen barrier layer of the floor heating pipe is of great significance to the oxygen resistance. The oxygen-blocking floor heating pipe is formed by two structures: three-layer co-extrusion and five-layer co-extrusion, and the floor heating pipe with the oxygen-blocking layer has strong anti-friction ability, which can increase the life of the floor heating pipe to a certain extent.

<> "Why do you need to use an oxygen barrier pipe for independent heating in your home?

For independent heating systems, there are a large number of metals in the heating equipment, such as radiators, floor heating water distributors, wall-hung boilers, etc., which are susceptible to oxidative corrosion by oxygen shaking and early gas, in order to reduce this corrosion, we need to control the oxygen content in the water.

But ordinary plastic tubes can't block the passage of oxygen molecules, so we need to use oxygen barrier tubes to reduce the oxygen in the water.

If there is rust on the metal surface, oxygen will aggravate the rust, so the use of oxygen barrier pipe can effectively prolong the service life of metal equipment.

For the wall-hung boiler heating system, the oxygen barrier pipe is an indispensable part, which can help us protect the metal equipment, prolong the service life, and improve the heating effect.

Therefore, when designing the heating system in Dongmeng, it is important to choose the oxygen-blocking pipe for pipe laying, which can effectively improve the safety and reliability of the heating system.

In this article, I will talk about whether the oxygen barrier tube is necessary.

What is an oxygen barrier tube? Is it possible for plastic floor heating pipes to get air?

You should have blown the balloon, whether the balloon will be flattened after a few days, is it because the mouth is not tight, in fact, the air runs through the surface of the balloon. The same goes for the floor heating pipes, which look like they don't leak water, but they leak air.

We know that metals corrode in the presence of water and oxygen, bacteria and algae.

In the presence of oxygen and water, it will live, reproduce, die.

In fact, plastics also age when exposed to oxygen. Therefore, for floor heating, oxygen resistance can prevent the aging of floor heating pipes and prolong the service life. Oxygen blocking prevents water separators.

Corrosion of valves and bathroom radiators can also prevent scaling, bacterial algae reproduction in floor heating, and the production of biological slime.

In life, we will find that there are fewer broken floor heating pipes, but some of the water separators and valves cannot be opened after a few years, and some leaks. Why? It's because of the corrosion mentioned above.

The oxygen barrier pipe can slow down the corrosion and oxidation in these places, prolong their life, and reduce the occurrence of water leakage. No one wants to go out for a day and come home full of water.

Customers who use floor heating early will find that floor heating is not as hot as a few years ago; Use a wall-hung stove.

customers will find that they are paying more for natural gas than before. This is the fact that scale and bioslime adhere to the walls of the heat exchanger and floor heating pipes in the wall-hung furnace, and the scale and sludge will reduce the thermal conductivity of the heating pipes.

As a result, the heat cannot be dissipated, the floor heating is not as hot as before, and the wall-hung boiler is more expensive than before.

After reading the above content, it is estimated that most people will feel that it is necessary to choose oxygen barrier tubes, especially for wall-hung boiler customers.

But central heating customers are still entangled, and I understand your entanglement.

What are the problems of central heating customers?

My home is blocking oxygen, but other people's homes are not necessarily, my floor heating is oxygen blocking, but the floor heating of other homes will still have oxygen in. That's right, in fact, the heating season is only about 100 days, and the remaining 260 days are not heated, and these 260 days are the main time period for floor heating corrosion, scaling, and biological slime. When heating, the heating company was afraid of causing damage to the pipes of his equipment, so it used demineralized water.

Deoxygenation equipment is also used, which is less prone to corrosion and bacterial reproduction. But as soon as the heating season is over, the water in each house is stagnant.

Corrosion, bacterial algae bloom begins, and lasts up to 260 days. At this time, if you are using an oxygen barrier pipe and the entrance valve is closed, all these damages have nothing to do with you.

Now I understand whether to choose oxygen barrier tubes, and if it doesn't work, why do the European Union, the United States, and Japan mandate the use of oxygen barrier tubes?

Of course it's necessary. There is an oxygen barrier structure, which can greatly reduce the oxygen infiltration rate of the pipeline, on the one hand, prevent the breeding and deposition of microorganisms, reduce the heat loss of the system, and on the other hand, improve the oxidation resistance of the pipeline itself, which can prolong the life of the pipeline itself.

Summary. Dear, hello, I have inquired for you that the difference between the oxygen barrier floor heating pipe and the ordinary pipe is the oxygen barrier pipe: good function, good oxygen blocking effect, quality *** ordinary pipe:

**Not expensive, the use effect is average, the quality is average, and the protection function of the floor heating system is not the same. Oxygen barrier pipe refers to the floor heating pipe with oxygen barrier layer, hoping to use the oxygen barrier layer to isolate the air from penetrating into the heating system through the plastic pipe wall, and the air enters the heating system, which will add the inner wall of metal parts to corrode. The production process is not the same.

The original floor heating pipe is a very ordinary floor heating pipe, it is very excellent in high temperature resistance and thermoplasticity, but it does not have an oxygen barrier layer, so the process will be simpler than the oxygen barrier pipe. **Different because the oxygen barrier tube has a good protective effect, and the production process is relatively advanced, so in the market**, the oxygen barrier tube will be more expensive than the non-oxygen barrier tube.

<> "What is the difference between the floor heating oxygen resistance pipe and the general stool rough through pipe?

1. The ingredients are different.

The main components of floor heating oxygen resistance pipes are polyethylene and octene, while ordinary pipes are polypropylene, polybutylene and polyethylene.

2. The production method is different.

The floor heating oxygen resistance pipe is made of medium density polyethylene and octene copolymerization, while the ordinary pipe is made of oxide cross-linking, silane cross-linking and electron beam cross-linking.

3. The role is different.

The floor heating oxygen resistance pipe has good flexibility, mainly used in hot water non-cross-linked polyethylene pipes, which will not rust and corrode, and can also effectively reduce construction costs and have a long service life. The ordinary pipe is mainly used in the pipe of low-temperature hot water circulation, which has impact resistance, can be used first-class, and will not cause pollution to the environment.

How much is the appropriate spacing between the floor heating pipes.

Its spacing is determined according to the size of the pipe diameter, for the northern region, it is usually rough with 20 calibers, so the spacing of laying floor heating is also about 20 cm, and most of the southern regions use 16 Ming town diameter floor heating pipes, the spacing is 15 cm, the distance between the heating pipe and the inner surface of the outer wall should not be less than 10 cm, and the distance between the inner wall is 20-30 cm.

Do underfloor heating pipes need to be cleaned regularly.

It is very necessary to clean the floor heating pipes, you can use pulse wave to clean the pipes, you can save the trouble of removing the pipes, and you don't need to use chemicals, so that the whole process is more convenient. In addition, cleaning the floor heating pipe is not a simple job, it is best to ask a professional to be responsible for the cleaning work, do not clean it yourself, to prevent damage to the pipe.

1. Accelerated system aging: Usually the aging of the system is due to the combined action of light, heat, oxygen, fatigue, etc. When oxygen enters the heating system through the floor heating pipes, there is a large amount of oxygen in the hot water flowing through the heating pipes, which may corrode the metal parts such as wall-hung boiler valves and heat exchangers, accelerate the aging of the system, and shorten the service life.

If an oxygen-blocking tube is used, the service life of the metal will be increased by 10-20 years without the action of oxygen.

2. When the hot water temperature is higher than 40, the thermal and oxidative aging of the heating pipe will be accelerated due to the penetration of oxygen into the heating plastic pipe body at high temperature. In Europe, oxygen-blocking floor heating pipes are widely used in hot water systems.
