What material is good for gas hose pipe?

Gas hose pipe is one of the essential materials used to connect gas pipes and gas appliances. Its quality directly affects the safety of gas usage. The material of the gas hose pipe also affects its use. The commonly used gas hose pipes are as follows:

PVC gas hose

PVC gas hose consists of three layers- an outer protective layer, a middle layer of steel wire explosion-proof net, and an inner PVC black rubber layer tube. These three layers are nested inside and outside of each other, providing the hose with functions such as explosion-proof, flame retardant, and scratch resistance. The service life of the hose is only two years because of problems such as aging of the rubber material and rat bites, and it is generally recommended to replace it after 18 months of use.

Stainless steel corrugated hose

The material of the stainless steel corrugated hose is 304 stainless steel, which is made into a spiral shape by using a hydraulic process, and then coated with a PVC protective layer. Therefore, its price is slightly higher than that of PVC gas hose. The stainless steel corrugated hose has the advantages of anti-aging, high-temperature resistance, anti-rat bite, non-falling off, corrosion resistance, and long service life. But it should be noted that the stainless steel hose should not be shaken back and forth, as this may cause metal fatigue or gas leakage at the threaded joints.

It is easy to find through the comparison of the two types of gas hose pipe that for our daily use of gas hose pipes in the home, stainless steel hoses are the preferred gas hose pipe for kitchens and other spaces due to their safety, daily use, corrosion resistance, and long service life.

Which type of connection for gas hose pipe's "head" is safer?

When we look at the connection of gas stoves, we can see that the stove connection can be divided into direct insertion and thread connection. During our daily use, the clamp in the direct insertion connection may be accidentally touched or other situations may occur, which may cause the rubber hose to fall off. The thread connection is screwed together by the spiral, so even if it is accidentally touched, no gas hose pipe falling off will occur, making it safer and more reliable than direct insertion connection.

Can gas hose pipes have "room for adjustment"?

According to regulations: When the hose is connected to the appliance, its length should not exceed 2 meters, and there should be no interface. Simply put, when using a hose, if the hose is too long, it may drag on the ground, causing deformation and rupture due to stepping or squeezing, or hooking or touching the connection part of the hose during use, which can easily cause gas leakage accidents. If the gas hose pipe is too long, it will increase the resistance of the intake pipe, reduce the heat flow rate of the stove, and it is easy to cause the connection to become loose. If the hose is too short, it is easy to cause the hose to come loose due to pulling.

Therefore, when we use gas hose pipes, the hose should have no "room for adjustment," and the length of the hose should not exceed 2 meters when connected to the stove.
