Common problems with hoses
1. Rat bite with rubber tube.
If the hose is bitten by a rat, it will cause gas leakage. If you use metal bellows, you can avoid rodent damage.
2. The hose falls off.
As the hose is not sturdy or used for a long time when installing the hose, the hose clamp will be rusted and loosened, which will easily cause the hose to fall off and leak. Users should pay attention to check whether the connections at both ends of the hose are tight to prevent the hose from falling off when the clamp is loose.
3. The hose is aging.
If the hose is used for a long time, problems such as aging and cracking may occur, which will cause the hose to leak air. The hose needs to be replaced after one and a half years of use.
4. The hose passes through the wall.
The relevant regulations for gas installation prohibit the hose from penetrating the wall.
5. The hose is too long.
The GB50028 Urban Gas Design Code clearly stipulates that the gas hose should not exceed two meters.
6. Use non-dedicated hoses for private connection.
Special remind users, must use a dedicated gas hose, can not be replaced by other hoses, and it is strictly forbidden to have joints in the middle of the hose. Remember not to connect and install multiple stoves without permission.
7. Embedded stove hose.
Generally hidden in the cabinet, it is easy to scratch, damage and fall off, and it is not easy to find, so it should be checked frequently.
The advantages of bellows over hoses
1. Anti-aging.
Rubber will become brittle, hardened, cracked, fractured and other aging phenomena under natural conditions, but stainless steel will not.
2. High temperature resistance.
The rubber hose is not resistant to high temperature, it will soften and catch fire under the flame. The stainless steel pipe body of the stainless steel corrugated hose can withstand high temperature, and the flame roasting will only affect the PVC protective layer on the outside.
3. Anti-rat bite.
The rubber hose is not resistant to rat bites, but the teeth of ordinary animals can't help the stainless steel body of the stainless steel corrugated hose.
4. Anti-falling off.
The rubber hose will not fall off naturally after the clamp is installed, but the safety cannot be guaranteed under accidental conditions such as aging shrinkage, external force pulling, etc. Stainless steel corrugated hoses are generally connected by threaded threads to prevent accidental shedding.
5. Corrosion resistance.
Rubber hoses are organic materials and are not resistant to oil, while stainless steel corrugated hoses are made of austenitic stainless steel, which can deal with common corrosive liquids, and the coated PVC protective layer also has a certain anti-corrosion effect.
6. Long life.
The service life of the rubber hose is 18 months, that is, one and a half years, while the service life of the stainless steel corrugated hose is 8 years, which is cheaper in a comprehensive calculation.
Of course, you can't be careless if you use a stainless steel hose. The back and forth disturbance may cause metal fatigue or air leakage at the threaded interface.
Gas users should update in time according to the design service life of gas burning appliances and gas hoses. It is recommended to use corrugated hoses and other anti-damage and anti-aging air hoses. Corrugated hose has the advantages of corrosion resistance, long service life, and anti-rat bite. It is recommended that residential users and catering households should try to use stainless steel corrugated hose to connect.
In addition to inviting professionals to inspect at home, citizens can also conduct self-inspection and self-inspection on gas appliances regularly in their daily lives: first smell the smell, a special odor is added to the gas, and it is easy to be noticed if it leaks; Secondly, when the gas is not used at all, check whether the number in the last red frame of the gas meter moves; then spray it with soapy water on each interface. If there is bubbling, it means that there is a leak.
