How to reform the gas pipeline?

Many times, the location of the gas pipeline does not conform to the decoration design scheme, which is neither practical nor beautiful. At this time, it is necessary to transform the gas pipeline, but the gas transformation is also one of the biggest security risks in the renovation. A little impropriety may cause safety problems in the future, so owners and friends need to know about it. So how to transform the gas pipeline? How much is the gas pipeline reconstruction? Next, I will bring you the process, cost and precautions of gas pipeline reconstruction. I hope you can help after reading it.

How to reform the gas pipeline?

Principle of gas pipeline reconstruction: In gas pipeline reconstruction, we should follow the principle of safety first and simple lines as far as possible, and then consider factors such as beauty and convenience. Generally speaking, the gas pipeline of new house does not need to be replaced, while the gas pipeline of second-hand house may be corroded and aged, so it needs to be carefully inspected before decoration, and necessary replacement and transformation are carried out to reduce the danger.

The owner shall not rebuild the gas pipeline without permission. At present, the relevant departments have mandatory regulations on the renovation and installation of gas pipelines. All kinds of decoration and installation shall not be carried out by the owner privately, and the home improvement company shall not change it at will under any circumstances. The owner shall carry out decoration and installation after the approval of the professionals of the property and natural gas company.

The gas pipeline is different from other pipelines in the home. No individual or decoration worker has the right to transform the gas pipeline. The transformation of gas pipeline must be operated by the gas company's filling station. Generally, the community will belong to a gas station, and the consulting property can contact them for gas transformation.

What material is good for gas pipeline?

1, the steel pipe can bear large stress, has good plasticity and is convenient for welding. Compared with other metals, under the same laying conditions, the pipe wall is thinner, so the metal consumption can be saved.

2. Cast iron pipe has excellent corrosion resistance, so it is widely used in urban low-pressure gas pipeline network. Cast iron pipes include gray cast iron and ductile iron pipes. It is not easy to weld, and the material is brittle, so it can't bear large stress, so steel pipes are still needed in areas with large dynamic load and important sections.

3. Plastic pipes Rigid PVC and polyethylene plastic pipes have a series of advantages, such as light weight, corrosion resistance, small friction resistance, tight joints, high tensile strength, simple construction and so on, which are widely used in medium and low pressure gas pipeline networks, but their aging problems need to be further studied and solved.

4. The steel skeleton polyethylene plastic composite pipe has the characteristics of high steel strength and good corrosion resistance of plastic, and can be used for medium and low pressure gas pipelines.

5. Other pipelines, foreign countries sometimes use non-ferrous metal pipelines, such as copper pipes and aluminum pipes. , and aluminum pipe is widely used, mostly used in indoor gas meters behind the pipeline. There are also glass steel pipes used as gas pipelines.

Gas pipeline reconstruction process:

1. installation application: the owner shall apply to the market development department for any project that needs to install pipeline gas. The gas company shall organize personnel to conduct on-site investigation, reply to the applicant, and be responsible for coordinating the design, installation, ignition and other aspects.

2. Opening an account: bring the notice of opening an account, ID card, real estate license or real estate lease contract within 5 working days, sign a civil gas supply contract, pay the account opening fee, and light the fire according to the arrangement table.

3. Transfer: With ID card, real estate license or house lease contract, the new tenant can consult the customer service department about the original tenant's gas payment and gas meter measurement, settle the gas fee, handle the transfer formalities and pay related fees.

4. Reconstruction and construction: the relocation, relocation, reconstruction and installation of indoor pipeline gas facilities need to apply to the gas company, pay the survey fee, conduct on-site survey and calculate the reconstruction fee, conduct on-site construction and settle the total cost.

Matters needing attention in gas pipeline reconstruction;

1. When the gas pipeline meets other pipelines, it shall meet the following requirements: when laid horizontally and in parallel, the clear distance shall not be less than150 mm; ; When laying vertically and parallel, the clear distance should not be less than 100mm, and it should be located outside other pipelines; Cross laying, the clear distance should not be less than 50mm；; Pipes cannot be hidden in walls; The gas pipeline cannot be installed in the wall like a cable, but must be installed outside the wall to facilitate problem detection and maintenance. And the adjacent wall surface cannot be a wall surface made of flammable materials such as wood. The pipeline should be short but not long; In order to reduce accidents, the gas pipeline should be short and not long, and try not to cross the bedroom and living room. If necessary, protective measures must be taken, such as putting a casing on the outside of the pipeline.

2. The gas meter must be ventilated: the gas meter in the kitchen should be placed in a ventilated place, which is safe and convenient for relevant personnel to check when charging at home. During the renovation, the owner shall not change the gas meter or move its position without authorization. If you need maintenance service, you should find the local gas supply unit, and the maintenance should be carried out when the gas is stopped. After the gas meter is reinstalled, it should be checked in time, and it can be put into use only after passing the pressure test and leakage test.

3. Hoses should not be used at the joint between gas appliance and pipelines: At present, stainless steel pipes are used at the joint between gas appliance and pipelines in most families, but there are still a few old houses connected by hoses. Hoses are prone to aging, and if they are not updated in time, they will easily lead to air leakage accidents.

4. Safety inspection should be carried out after the pipeline transformation: in order to prevent the damage of gas pipelines and fittings during the transformation, safety inspection should be carried out in time after the transformation to see if there is gas leakage. If there is no problem after inspection, it can be put into use, otherwise it should be repaired by professionals in time. If air leakage is found during the inspection, it shall promptly notify the professionals in the gas supply department for maintenance.

How much is the gas pipeline reconstruction?

The charging standard for gas pipeline renovation is: the embedded fee is charged for multi-storey houses according to the construction area of 29 yuan/square meter, and the height of each household does not exceed 3,500 yuan. The embedded fee is charged for townhouses according to the construction area of 29 yuan /m2, and the height of each house does not exceed 9000 yuan.

For high-rise residential buildings with a building height equal to or greater than 20m above the ground, the embedding fee shall be charged according to the construction area of 30 yuan /m2, and the height of each household shall not exceed 3,500 yuan. Affordable housing, low-rent housing and other affordable new complete sets of housing, according to the construction area of 26 yuan/square meter, the height of each household does not exceed 2800 yuan.

For residential buildings that have been put into use but are not ventilated, pipeline gas business enterprises can charge residents a renovation fee of 2,200 yuan each.
