How much damage does a gas pipeline really have?

There's no harm in standing still. If it leaks, or even triggers **, the damage will be too great. Walls and houses will collapse.

1. The gas pipeline is wrapped or buried in the wall or under the tile;

2. After changing the use of the kitchen, the gas facilities are modified in the bedroom or bathroom;

3. Change the direction of the gas pipeline and the location of the gas meter without permission;

4. The gas water heater is not effectively installed with a flue or the flue pipe is connected to the public flue.

In particular, some household users install water heaters with private tees, which seriously threatens the safe gas supply.

The hazards of gas leakage can be summarized into two points:

1. Suffocation. With the leakage of gas, accumulation will occur in the leakage area, especially in a closed or relatively closed space, the proportion of gas in the air will gradually increase, and then the proportion of oxygen in the air will gradually decrease, and people or animals in this environment will have difficulty breathing, or even suffocate to death.

Second, deflagration or **.

With the leakage of gas, accumulation will occur in the leakage area, and as the proportion of gas in the air gradually increases, it will reach the limit of the gas, and at this time, open flames or sparks will occur.

Yes, common causes of corrosion in indoor gas pipelines:

1. The choice of paint or coating is unreasonable.

Usually maintenance and maintenance, gas companies or personal maintenance, are in the hardware store or building materials market to buy ordinary anti-rust paint, ** in the tens of yuan to dozens of yuan, the choice of paint is not professional, the quality of the product is uneven, can not play the role of anti-corrosion, sunscreen, use a few months will fall off, invalid.

2. The substrate is damp and the rust removal is not in place.

Condensate is often found on the surface of natural gas pipelines and water supply pipelines.

After the coating is dry, the moisture is still on the surface of the pipe, forming the lower part of the coating to corrode, and after a long time, the paint film bulges and cracks, forming rust water and rust layer.

3. Destruction by external forces.

Outdoor pipelines are susceptible to external damage, resulting in scratches, and corrosive media infiltrates to form rust, corrosion, and coating damage.

4. Weather resistance of paint or coating.

Difference. After half a year of outdoor use, ordinary paint will fade, lose color and chalify, which cannot play a long-term anti-corrosion role.

Precautions: The corrosion of indoor gas pipelines, because it is indoors, has more direct harm and threat to the life and property of users, and is a major source of danger.

The gas company only transfers the commercial and economic interests of gas supply for itself, regardless of making residents bear the risk of life and property accidents such as flammable, explosive, and diffuse.

Natural gas accidents occur from time to time, education and publicity should be strengthened, the safety inspection system should be implemented, the inspection and maintenance should be done well, the timely detection and disposal at any time, the inspection and maintenance should avoid luck, prevent the slightest, and avoid carelessness.

Summary. Hello dear, happy to answer for you. The construction of natural gas pipelines is safe, environmentally friendly and convenient, and other advantages are beneficial to the country and the people, especially the construction of oil pipelines and natural gas pipelines, which is of great significance to our country, one is to diffuse China's energy construction channels and ensure national energy security, the second is to alleviate China's energy shortage and promote China's economic development, and the third is that the pipeline transportation cost is low, the consumption is high, safe and orderly.

Hidden in the "teething stick" of a mouse

The rubber hose has a unique rubber smell, and the gas hose is close to the stove, and the stove has more oil residues, and the rat likes smelly items, so it is easy to gnaw on the hose and cause gas leakage.

Hidden two hoses are overdue.

The service life of household gas hoses is generally 18 months, and it is easy to age, crack, blister or damage when used beyond the expiration date. Otherwise, it will become a "timed bomb" in the kitchen, and it is recommended to replace it at the end of the period.

Hidden Danger 3: The hose length is too long.

According to the regulations of the national government, the length of the hose should not exceed 2 meters, as the hose is a weak link in the indoor gas facility, the longer the hose means the greater the risk, easy to bend, aging, affecting the normal use of gas.

Hidden danger four hoses are too close to the fire source.

Do not put the gas hose close to the stove surface, so as not to be burned by the flame and deteriorate; Do not press the gas hose to avoid blockage and affect the continuous gas supply.

Hidden 5. Wrap paper and other items around the hose.

Many people wrap the hose with newspaper, plastic wrap, etc., in order to prevent the hose from getting oily, which is extremely dangerous, and once a spark appears, it is easy to ignite the hose.

Hidden six hoses whether to penetrate the wall.

According to the regulations for the construction and quality acceptance of urban gas indoor engineering, the gas hose shall not pass through the walls, floors, ceilings, doors and windows under any circumstances, mainly considering that the hose will be damaged in the wall, resulting in gas leakage and is not easy to find.

Hidden danger 7: Privately connected gas hoses.

In order to ensure gas safety, standard gas pipes should be used, and other non-gas hoses should not be used instead, and professional gas company staff must be found to replace the hoses to ensure safety and reliability.

You want to avoid the hidden dangers of gas hoses.

The best way to do this is to replace the metal hose.

Compared with the round and early smoothness of ordinary hoses, the safety of metal soft orange wax pipes is significantly higher!

Pipeline gas is toxic. The gas itself contains carbon monoxide, and leaks can directly cause carbon monoxide poisoning. In addition, if the leakage is very large, the gas will cover the air in the room, which may lead to a lack of oxygen.

The gas itself has no smell, but because there is a fear of leakage in life, the gas will be odorized (ethyl mercaptan) treatment before the civil gas supply, so that the gas has a smell similar to rotten eggs, so that the leakage is easy to find. <

Pipeline gas is a form of gas supply that uses pipelines to deliver gas to customers.

The advantages of piped gas are:

Safety, stability, environmental protection and cleanliness, easy to use, is one of the hallmarks of modern life. There are many types of pipeline gas sources, such as oil-to-gas, natural gas, coal-to-gas, liquefied petroleum gas, etc. Different gas sources, gas components, Huabai index, and calorific value are different.

The type of pipeline gas source is: oil-to-gas, that is, heavy oil pyrolysis gas. After the gas is produced by the oil-to-gas plant in Jishan, Huangpu, the gas is gradually depressurized through underground pipelines and transported to customers.

Piped gas refers to a system that transports gas through pipelines to a user's home or commercial single-only touch** fuel use. Generally, the pipeline gas system consists of a gas ** station, a gas transmission pipeline, a gas metering equipment and a user terminal.

Gas can be either natural gas or liquefied petroleum gas (LPG). Natural gas is a natural resource stored underground, mainly composed of methane, which can be piped to the user's home. Liquefied petroleum gas (LPG) hail is a liquid petroleum gas, including propane and butane, commonly in the form of bottled gas, which can also be piped to the user's home.

Pipeline gas has the advantages of convenience, safety and economy, and users do not need to buy and replace gas cylinders, but directly obtain the gas they need from the pipeline.

Thank you! As someone who has experienced the use of piped gas, I would love to share my perspective and experience with you.

For me, piped gas is a very convenient and efficient form of energy. It pipes to our homes**, eliminating the hassle of needing to change fuel tanks frequently when using LPG or other alternative fuels. In addition, the use of piped gas can also avoid the floor space and storage safety problems of gas tanks.

I remember how happy my family and I were when we first installed piped gas. We no longer need to buy gas canisters on a regular basis, and ** are continuous and uninterrupted. After using piped gas, our family's life has become more convenient.

In addition, piped gas is also very efficient to burn because it provides a stable gas flow and pressure. This allows our stoves and water heaters to heat up and deliver the required temperature quickly. In contrast, I used traditional fuels such as coal and wood, which burn less efficiently, are not only time-consuming, but also produce more exhaust gases and pollutants.

However, the use of piped gas also needs to pay attention to the safety of oak picking. During installation and use, we must follow the relevant safety guidelines to ensure that the sealing and leak-proof functions of the piping system are working properly. Regular inspection and maintenance of the piped gas system is also necessary to ensure its safety and reliability.

Overall, piped gas is a very convenient, efficient and safe energy option for me. It brings convenience to our lives and allows us to enjoy family life more comfortably.

Summary. Influential. The gas flow rate is equal to the product of the cross-sectional area and the gas flow velocity, and the larger the diameter of the pipe mouth, the larger the cross-sectional area, and the greater the gas flow.

Flow rate is the amount of fluid passing through a certain cross-sectional area per unit time. This amount is expressed in terms of the volume of the fluid and is called the instantaneous volume flow rate (QV), or volume flow rate for short; The quality of the flow is called instantaneous mass flow (QM), or mass flow for short. The measurement of the flow rate of a fluid flowing in a certain channel is collectively referred to as flow metering.

The gas flow rate adopts a gas flow meter. The gas flow measurement unit adopts standard cubic meters, which we often call imitation mass units, because it seems to be a volume unit, in fact, it is a mass unit, it has nothing to do with the pressure and temperature of the place of use, if the gas is natural gas, the mass of 1 standard cubic meter is also related to the composition of natural gas, and it is more reasonable to use energy units when measuring natural gas ** because of the same natural gas quality, if its components are different, its calorific value is also different.

Does the size of the natural gas pipeline have an impact on the amount of gas used?
