Discussion on environmental safety and replacement safety technology of urban gas pipeline

the types of urban gas include liquefied petroleum gas, natural gas, coal gas, etc. At present, the urban gas industry is in a period of great development. In the past, artificial gas and liquefied petroleum gas were the main sources of urban gas. With the rapid growth of natural gas in cities, there has been a fundamental change. Natural gas has become the main source of urban gas, forming a national and even transnational gas supply network. Gaseous fuels account for 20% of the world's energy composition and play a great role in economic development and atmospheric environment improvement. It is very important to ensure the environmental safety and replacement safety of gas pipeline

1, gas pipeline environmental safety technology

1.1 prohibited behaviors within the scope of safety protection

it is prohibited for any unit or individual to engage in the following activities endangering the safety of pipeline facilities within the scope of safety protection of gas pipeline facilities:

a) under low pressure, medium pressure Within 0.7m on both sides of the center line of the secondary high-pressure pipeline facilities or within the safety protection range of 0.7-6.5m on both sides of the center line when no effective safety protection measures are taken, borrow soil, build canals, plant deep-rooted plants, discharge corrosive substances, stack bulk materials and dangerous chemicals, build buildings or structures, pile driving or jacking operations

b) plant deep-rooted plants within 6.5m on both sides of the center line of high-pressure and ultra-high pressure pipeline facilities, take soil, build canals, discharge corrosive substances, stack bulk materials and dangerous chemicals, build farms, and Build a wharf or its 10. Push the lower pressure plate into other buildings (or structures) in the experimental machine, pile driving or jacking operations, build or rebuild (expand) railways, highways, bridges, canals, overhead power lines, bury underground electric (optical) cables, and set up safety or lightning protection grounding bodies

C) blasting operation shall be carried out within 50 m on both sides of the center line of high-pressure and ultra-high pressure pipeline facilities or within 50 - 500 m on both sides of the center line when no safety protection measures are taken

d) other pipeline facilities are not laid within the specified distance on both sides of the pipeline facilities in accordance with the requirements of relevant national gas engineering design specifications and fire protection technical specifications

1.2 requirements for the safety protection of pipeline facilities involving rivers

for pipeline facilities along, across, across, across, across dikes, and near rivers, the pipeline facility ownership enterprise and the river management department shall determine the scope of safety protection and set signs according to relevant national regulations. If the waterway is involved, the opinions of the waterway administration department shall be sought

1.3 operation requirements beyond the safety protection scope

blasting, piling, building large buildings or structures outside the safety protection scope of pipeline facilities, which may damage or endanger the safety of pipeline facilities, shall be carried out after the construction unit and relevant pipeline facilities ownership enterprises reach an agreement and take corresponding safety protection measures

1.4 lifting of prohibition

for the operation within the scope of pipeline safety protection, if it is really necessary to carry out the operation, it needs the consent of the planning, fire protection and other administrative departments, and it can only be carried out after the construction unit and the relevant pipeline facility ownership enterprises reach an agreement through consultation, and take corresponding safety protection measures for the pipeline facilities

removal of illegal occupied structures of such 3D printed conduits 1.5

for illegal buildings or structures occupying pipeline facilities, the district or county people's governments may organize relevant departments to remove them, and the expenses incurred shall be borne by the illegal construction units or individuals

1.6 construction avoidance

for the protection of pipeline facilities caused by the encounter between the new, reconstructed and expanded construction projects and the existing pipeline design, the construction unit and the management facility ownership enterprise shall negotiate and conclude an agreement to clarify the responsibilities and economy of both parties on the protection of pipeline facilities. If the newly-built, reconstructed or expanded construction project really needs the transformation, relocation or addition of safety protection facilities of pipeline facilities, the construction unit shall conclude an agreement with the enterprise that owns the pipeline facilities and take corresponding remedial measures, and report the agreement to the MFGMO for the record

1.7 construction consultation

before commencement, the construction unit shall consult with the pipeline facility ownership enterprise about the underground pipeline facilities and construction protection requirements, and organize disclosure to the construction unit. The enterprise that owns the pipeline facilities shall give a written reply within three days
