What are the gas steel wire braided rubber hoses, which is safe, and how to choose时间：2021-09-13浏览次数：378
The safety of gas cannot be ignored, especially in the choice of gas steel wire braided hose at home.
However, some friends have a lack of understanding of gas steel wire braided hose, so that they mistakenly use the water pipe as a gas pipe. They do not realize that there is a great potential safety hazard in this way. Once a gas leak occurs, the result is unimaginable. Some friends said that steel wire hose should be used for safety, some said it was unnecessary, and some said that metal hose should be used. Everyone's views are different. In the final analysis, they don't understand gas steel wire braided hose. Which kind of gas steel wire braided hose is more safe and applicable?
In this issue, I'll talk to you about domestic gas steel wire braided hose and see what kind of domestic gas steel wire braided hose there are after all? Analyze the advantages and disadvantages of various hoses, whether it is necessary to use steel hose and which hose is good after all.
Common gas steel wire braided hose
The so-called gas steel wire braided hose is a section of flexible pipe in front of the gas equipment. Its main function is to give a certain amount of compensation to facilitate the connection, and also to avoid the interface tightening caused by the movement and vibration of the gas equipment under the condition of hard connection.
Common gas steel wire braided rubber hoses are mainly as follows:
1. Rubber plastic gas steel wire braided hose
Rubber plastic gas steel wire braided hose is the first hose used for gas. During the earliest use of gas, rubber hose was mainly used. The main component is rubber. There are usually three layers. The inner and outer layers are made of corrosion-resistant rubber, and the middle layer is made of fiber braided layer, so as to increase the pressure.
At present, many gas steel wire braided rubber pipes are made of PVC, with different layers, and at least three layers. They are internal and external corrosion-resistant PVC materials, with fiber braided layers in the middle, and some use steel wire braided layers to increase pressure bearing ability. There are also up to 5 floors.
Advantages: low cost, good flexibility, simple connection and easy operation.
Defects: because its main material is either rubber or PVC, it will age, harden and crack during long-term use, which is easy to form gas leakage. Because of its soft material, it is not resistant to wear and tear, and may also cause rat bites. And the hoses made of these two materials are not resistant to high temperature, which is also a defect.
2. Armored gas steel wire braided hose
The so-called armored gas steel wire braided hose belongs to a kind of metal hose, which also has three layers. The innermost layer is usually plastic hose, the middle layer is metal winding pipe, and the outer layer is flame-retardant and corrosion-resistant PVC protective sleeve.
Advantages: not easy to wear, anti mouse bite, not easy to bend, good flexibility.
Defects: this kind of gas steel wire braided hose can bear ordinary pressure. In addition, most of the joints are plastic joints, which are easy to age.
3. Aluminum plastic gas steel wire braided hose
The aluminum plastic gas steel wire braided hose is generally three-layer in structure, with polyethylene inside and outside and metal aluminum in the middle.
Advantages: the pressure bearing capacity is strong, and the whole pipe can be used for underground laying, which is resistant to rat bite, aging and corrosion.
Defect: poor flexibility, bending type requires bender, otherwise it is easy to bend.
4. Stainless steel bellows
Stainless steel bellows is a gas steel wire braided rubber hose that has been developed in recent years. Its main structure is two layers, stainless steel bellows and PVC surface protective layer.
Advantages: strong pressure bearing capacity, the whole root can be used for underground laying, anti rat bite, not easy to aging, corrosion resistance, good plasticity.
Defects: high cost and poor flexibility.
Can steel wire hoses be used for domestic gas?
As for the gas steel wire braided hose, the steel wire hose refers to the hose with steel wire braided inside, that is, the rubber plastic hose we mentioned above, which replaces the fiber braided layer used inside to increase the pressure bearing ability with the steel wire braided layer.
This kind of gas steel wire braided hose, if it conforms to its consumption specifications, is a normal product. Of course, it can be used and is relatively safe. However, as for domestic gas, there is no need to deliberately purchase this kind of steel wire hose. As for rubber hose, the steel wire in it can't prevent rat bites. Moreover, the pressure of domestic gas is enough for ordinary fiber braided hose. In addition, this kind of steel wire hose can't effectively avoid the normal aging of rubber hose. Therefore, there is no need to deliberately pursue this kind of steel hose.
In addition, it should be clarified that there is a kind of steel wire braided hose at present, and its surface has no protective layer. This kind of hose is generally used as water pipe, not as gas. We should never use this kind of hose as a gas steel wire braided hose.
After all, which kind of hose is safe and applicable?
For the four kinds of gas steel wire braided hose we introduced above, stainless steel corrugated hose is the most safe and applicable, and it is also a kind of gas steel wire braided hose that is compared and recommended at present.
Among them, rubber and plastic hoses are easy to age, not wear-resistant, and easy to be bitten by rats, which is not safe; Due to its poor flexibility, aluminum plastic pipes are generally not used for the connection of gas equipment; Although armored metal hoses can avoid rat bites, their joints are still prone to aging, which is not safe. Therefore, at present, stainless steel corrugated hose is safe and applicable.
Gas steel wire braided hose is a very important part of home gas safety. Choosing a good gas steel wire braided hose will greatly increase the safety index of home gas use. This article tells you about four common types of gas steel wire braided hose, and also gives you an explanation on whether it is necessary to use steel wire hose. At present, the most safe and applicable gas steel wire braided hose is stainless steel corrugated hose. Here, I hope you should pay attention to safety when looking at gas.
