The gas pipeline is the most important part of the kitchen. We all know that the gas pipeline cannot be easily modified. However, when we finish renovations, we often have to make some minor changes to the gas pipeline. What are the precautions for gas pipeline retrofitting? The first thing that needs to be understood is the process of reforming gas pipelines. In general, the transformation of gas pipelines is based on safety, followed by beauty. The transformation of gas pipelines also requires the gas company to apply for transformation and report preparation. Only with the approval and support from the gas company can special gas and gas pipelines be transformed by construction personnel. After the success of the transformation, the owner will pay the gas company's property a corresponding fee. Gas pipeline renovation precautions First, the principle of safety first At present, the relevant departments have mandatory regulations for the transformation and installation of gas pipelines. Various transformations and installations must not be carried out by the owners themselves, and the home improvement companies must not arbitrarily change them under various circumstances. The industry is mainly responsible for property and natural gas companies. After the professional's approval, it will be transformed and installed. First apply, the indoor pipe gas facilities move, move, change, install the need to apply to the gas company, pay survey fees, site survey and estimate conversion costs, home construction, settlement of the total cost. Gas pipelines are different from other pipelines in the home. No individual or decoration worker has the right to renovate the gas pipelines. The gas pipelines must be reconstructed by gas stations. Second, the line concise principle The transformation of gas pipelines should follow the principle of streamlined refinement as far as possible, and consider factors such as aesthetics and convenience on this basis. The gas pipelines of new houses generally do not need to be changed, and the gas pipelines of second-hand houses may be rusted and aged. This requires careful inspection before renovation, and necessary replacement and modification to reduce the risk. Third, the principle of pipeline renovation The pipeline cannot be hidden inside the wall. The gas pipeline cannot be installed in the wall like a cable. It must be installed outside the wall to facilitate the detection and repair of problems. The wall near the wall must not be a flammable material such as wood. The pipeline should be short and not long. In order to reduce the occurrence of accidents, the gas pipeline should be short and not long. Try not to cross the bedroom or the living room. If it is necessary to pass through, be sure to take protective measures, such as putting a pipe sleeve outside the pipeline. It is not advisable to use hoses at the junction of burning appliances and pipes. At present, stainless steel pipes are used at most of the connections between domestic burning appliances and pipelines, but there are still a few old houses that use hoses. Hose is easy to age, and if it is not updated in time, it can easily cause a leak. After the completion of pipeline reconstruction, safety inspection is required. To prevent damage to the gas pipelines and fittings during the renovation, safety inspections should be conducted in a timely manner after the renovation to check whether gas leaks occur in the gas pipelines. After the inspection, no problems are found. Put into use, otherwise you should find a professional to repair. If leaks are found during the inspection, notify the gas supply personnel for maintenance. Fourth, gas gas meter placement principle The gas meter must be ventilated and the gas meter in the kitchen should be placed in a ventilated location. This is not only safe, but also convenient for the relevant personnel to check when they are charged. During the renovation, the owner shall not change the gas meter himself or move his position without permission. If maintenance services are required, local gas supply units must be found. Maintenance should be carried out when the air supply is stopped. After the gas meter is reinstalled, it must be promptly inspected. After the pressure test and leak test are qualified, it can be put into use. Causes and Countermeasures of Leakage of Gas Pipeline External factors (1) Construction damage 1 Foundation exploration destroys pipelines. 2 The excavator cuts off the pipe. 3 The bulldozer infers the condensate drain pipe. 4 The pavement breaker breaks the pipeline. 5 Destruction of pipeline foundations leads to sinking of foundations and uneven settlement and fracture of pipelines. (2) Heavy-duty roller compaction The intersection of the low pressure pipeline. The traffic load at the traffic intersection acts on the gas pipeline through the soil and forces the pipeline. At the same time, the effect of the flow load also causes uneven settlement of the road's backfill soil, resulting in uneven settlement of the pipeline foundation. Under the effect of two-way force, The gas pipeline can withstand the combined stress of the loads and break off. 2 courtyard pipeline. The courtyard pipeline inside the residential area is traditionally built without considering the heavy loads. However, due to the needs of the later construction of the community and the requirement for uniform disposal of garbage, many trucks also entered the community, causing the courtyard pipeline on some pavements to be broken due to heavy loads and leaking. (3), illegal buildings occupy pipelines 1 The safety distance between pipelines is not enough. Because the vertical distance is not enough to be built on the gas pipeline, the gas pipeline will be carried and fractured under the action of long-term downward force, resulting in leakage; Or the net distance is not enough to form a lateral thrust on the gas pipeline, resulting in displacement caused by pipeline welding Tears, leaks. 2 The illegal buildings occupy pipelines. The illegally constructed buildings and fixtures on the market such as market facades occupy pipelines for a long period of time, so that the gas pipelines under the action of the load for a long time will gradually sink due to stress and cause fractures. 2, management factors (1) The construction quality is poor and the specification requirements have not been strictly enforced, resulting in congenital defects in the pipeline, corrosion and fracture during operation, and gas leakage. (2) The quality of the pipe is poor, and the pipeline leakage occurs due to insufficient strength and thickness during operation. (3) Aging or maintenance of facilities is not timely. Aging or maintenance of facilities will not cause leakage accidents in time, such as leakage of joints. (4), illegal operation. The poor management of the job site leads to the formation of a mixture of gases and causes a detonation. Editor's summary: In short, any decoration company does not have the qualification for gas reform. All gas reform projects must be operated by the relevant units and staff of the gas group. The attention of the gas pipeline reform is that everyone must strictly abide by it. If not, In the most necessary circumstances, try not to reform the gas pipeline. Gas pipelines must do regular safety inspections to eliminate potential safety hazards. Old Building Renovation Old Renovation Space Rebuilding Gas Pipeline
