With the development of the times, people's acceptance of information is more and more extensive. However, in such a large amount of information today, the knowledge of the gas pipeline is increasingly ignored. We should re-recognize security and family responsibilities. Gas pipe, let's answer the questions that people have asked recently.Stainless steel bellowsThere are two types of gas pipes, one is stainless steel bellows and the other is gas pipe hose (metal coated hose); each has advantages and disadvantages. It is recommended to choose according to your own situation. The advantages and disadvantages of the two hoses are as follows:

1、Stainless steel bellows(also known as stainless steel bellows) material for 304 or 316 stainless steel, can be selected according to different requirements. 316 used in demanding industries. The industry has no special requirements for gas pipelines. 304 specifications can already be met. The stainless steel bellows has the characteristics of anti-aging, high temperature resistance, anti-rat bite, anti-fall, corrosion resistance, and long life. Advantages. But the price is more expensive than the gas pipe hose (metal coated hose). When using stainless steel bellows, you need to be careful not to stir back and forth, which may cause metal fatigue or air leakage at the threaded interface. On the other hand, the stainless steel bellows should not be too long. If it exceeds 1.5m, it needs to be fixed; when the external force causes mechanical damage, the naked eye cannot determine whether there is a crack or stress concentration, it must be replaced.

2. Gas pipe hose (metal coated hose), generally divided into three layers, the innermost layer is PVC rubber layer inner tube, the middle is the metal protective layer, the outer layer is the flame retardant layer. The metal protective layer plays the role of holding the PVC inner tube, and the protective layer plays the role of flame retardant and anti-rat bite and scratch. PVC pipe at both ends of the price is cheaper. Suitable for household use where liquefied gas is connected to liquefied gas tanks and requires regular ventilation. Compared with the first stainless steel bellows, it is more convenient to replace.

From the above two kinds of non-material hose, stainless steel bellows and gas pipe hose, each has its own advantages, depending on where you use it. The conclusion is obvious, there is no difference between stainless steel bellows and gas pipe. However, home gas safety is not only a problem of gas pipelines, but also depends on the good habits of individuals using gas pipelines. In addition to inviting professionals to inspect, we also need to conduct self-inspection and self-inspection of gas appliances in daily life: first smell the smell, and add a special smell to the gas, which is easy to be discovered. Pay attention when a leak occurs; secondly, when the gas is completely unused, check whether the number in the last red box of the gas meter moves; then spray soapy water on each interface. If bubbles are found, it means there is a leak. Gas into thousands of households, safety is a matter of everyone!
