[Shuangbei Natural Gas Decoration Regulations] Can gas pipes be moved without permission when changing the layout of the kitchen? Greater Taipei gas and Xinxin gas piping specifications, microcomputer gas meter application and hidden pipe leakage taboos

The defense line of Shuangbei kitchen reform pattern: regulations and safety of natural gas pipelines

When renovating or renovating antique houses in the greater Taipei area, open kitchens and island bars are the layout designs that many homeowners dream of. However, in order to adjust the location of the gas boiler, many people often ask plumbers or interior designers during the design stage: "Can the gas pipe be cut off and re-pulled, or can it be more beautiful by burying the gas pipe under the cement wall and floor?" The answer is:This is a serious illegal act, and it hides a huge safety hazard of gas deflagration! Taiwan has extremely strict regulations on household natural gas (NG) piping. Unauthorized modifications to natural gas pipelines will not only result in the gas company shutting off the gas, but may also lead to criminal liability in the event of an accident.

Fact check: Three hard red lines in Taiwan’s natural gas regulations

According to the "Natural Gas Business Law" of the Republic of China, the "Construction Technical Rules" of the Ministry of the Interior and the "Iron Pipe Piping Specifications for User Gas Equipment", the construction of natural gas pipelines has the following red lines that cannot be violated:

• Red Line 1: It is strictly prohibited to bury natural gas pipelines inside walls and floors (concealed pipe construction is strictly prohibited): Regulations clearly stipulate that indoor natural gas pipelines must adopt an "exposed pipe configuration" and must be kept in a conspicuous location with good ventilation. If an iron pipe or hose is wrapped under a cement wall or cement floor (concealed pipe), once the pipeline is slightly ruptured due to earthquake pull, the leaked natural gas (methane CH₄) will accumulate in the closed cement gap, and a violent gas explosion will occur when encountering a tiny electric spark!
• Red Line 2: The main pipe in front of the gas meter and the displacement of the gas meter must be carried out by the public gas company: Shuangbei area is served by "Greater Taipei District Gas", "Xinxin Gas", "Xintai Gas", "Xinzhi Gas" and other operators according to the jurisdiction. The pipeline connecting the common riser of the building outside to the indoor "gas meter" is a public utility property. Any unauthorized dismantling or moving of the gas meter location is illegal, and a "management modification application" must be submitted to the gas company to which the gas company belongs, and the gas company will send personnel to install the meter and carry out the work.
• Red Line 3: Length and material restrictions of the hose behind the meter: If a rubber hose is used for the pipeline connected from behind the gas meter to the gas furnace or water heater, its length must not exceed 1.8 meters, and it must use a qualified "stainless steel corrugated hose" with a wire rod-proof layer or a galvanized iron pipe.

Strongly recommended to upgrade: security mechanism of microcomputer gas meter (Smart Gas Meter)

In conjunction with the Ministry of Economic Affairs’ promotion of natural gas user safety upgrades, the Shuangbei region has vigorously promoted the replacement of "microcomputer gas meters". Compared with traditional mechanical gas meters, microcomputer gas meters have built-in highly sensitive micro-sensors and solenoid valves, and have three automatic interruption (automatic gas cutoff) functions:

1. Automatic interruption of strong earthquakes with a magnitude of 5 or above: The greater Taipei area is located in a seismic zone. When an earthquake with a magnitude of 5 or above is sensed, the microcomputer meter will automatically lock the air valve within a few seconds to prevent the earthquake from breaking the pipeline and causing a secondary fire.
2. Small air leakage and abnormally large air leakage interruption: When a long-term trace leakage in the pipeline is sensed, or a sudden rupture of the pipeline causes an abnormal surge in flow, the air source will be immediately cut off.
3. Automatic cut-off for overtime operation: When the gas stove continues to cook for longer than the normal time (for example, when you forget to turn off the fire when cooking soup), the gas meter will determine it is abnormal and automatically shut down the gas source, effectively preventing dry fires.

Shuangbei Natural Gas Pipeline Renovation Application and Budget CapEx Abacus

For owner-occupiers or real estate flip investors who want to remodel their kitchen layout, the standard process and fees for compliant natural gas pipe modifications are as follows:

Conclusion: Comply with the air pipe configuration, taking into account both aesthetics and ultimate safety

While kitchen decoration pursues modernity and broad vision, it must not be at the expense of natural gas safety. The only way to prevent gas explosion accidents is to maintain the open-pipe configuration of natural gas pipelines, use inspected stainless steel bellows, and handle gas meter relocation and microcomputer upgrades through formal channels such as Greater Taipei Gas or Xinxin Gas. During real estate transactions and renovations, a compliant natural gas inspection certificate is a golden sign that ensures peace of mind for the whole family and maintains the resale value of the asset.
