Do you know how long the rubber hose that connects the gas appliance should be changed? When I heard this question, many people will be a bit ignorant".

"Will the pipe have to be replaced regularly?" Isn't that all right? My family has been using it for 7 years, and it doesn't look like a problem!"

"Never changed", "do not know to change", "should not matter.""......

Do you, like most people, never notice the "last 2 meters" hose in the kitchen?

If you are using piped gas or decorating your house, you are about to become a piped gas user, so this information may be useful to you:

Data show that 99.9% of household gas accidents are due to negligence, and 7 out of 10 gas accidents are caused by aging or rupture of the hose. Relative to the gas access pipe and gas appliances received attention, at the end of the gas transmission, residents of the kitchen in the "last 2 meters" hose, but it is easy to ignore the public. Once the hose is aged and cracked, a gas leak will occur. If you don't care, the hose will become a "stealth mine" at home". The general use of hose length is 18 months; easily bitten by rats and high temperature resistant, easy to leak. While the stainless steel corrugated hose and gas hose compared with corrosion resistance, good flexibility, under normal conditions, the use of over 10 years; high temperature, strong material, not easy to be damaged, can reduce indoor deflagration caused by non-human * *.

Advantages of stainless steel corrugated hose

Anti-aging. Under natural conditions, rubber will become brittle, hardened, cracked, broken, etc., while stainless steel will not.

High temperature resistance. The rubber hose is not resistant to high temperature, fire, fire will soften. Stainless steel corrugated hose stainless steel tube which is resistant to high temperature, fire will affect only the protective layer is covered outside the PVC.

Rat bite. Rubber hose does not prevent rat bite, but the teeth of ordinary animals can not be stainless steel bellows hose stainless steel tube.

Anti dropping. The rubber hose will not come off naturally after installing the clips, but it can not guarantee the safety in the case of aging, shrinkage, external force pulling and so on. Stainless steel corrugated hose generally adopts screw thread connection, can withstand an adult pull, can prevent accidental shedding.

Corrosion resistance. The rubber hose belongs to organic materials, not oil, and stainless steel corrugated hose using austenitic stainless steel, general corrosive liquids can deal with common PVC, and protective layer coated with a corrosion resistance.

Long service life. The service life of rubber hose is 18 months, that is, one and a half years, while the life of stainless steel corrugated hose is 8 years, and the comprehensive calculation is cheaper.

How can I change it? These details need attention

Because the stainless steel metal corrugated pipe diameter than the rubber hose slightly thick, if the reserved hole cabinet is not big enough, so it need to expand; if the rubber hose connecting the gas water heater is a wall embedded, embedded pipe is rough enough, then it can only be stainless steel metal bellows on the outside. As long as the people do not mind drilling, do not mind the impact of beauty, you can install and replace.
