Gas marker posts play a very important role in people's lives and the safe gas supply of cities. If the natural gas pipeline is cut off, the consequences will be unimaginable.

It is buried along the natural gas high-pressure pipeline, painted with yellow marks, with a cross-section of 15 cm in size and a total length of more than 1 meter, and about 60 cm above the ground. The marker post is equipped with "gas pipeline, gas telephone, pipeline pile number, pipeline direction, electronic Patrol information button". Setting the marker post can play a role of prompt and warning.

The line patrol and emergency repair personnel can compare the "electronic Patrol information button, pipeline direction and pipeline pile number" on the marker post. Quickly identify the location of the pipeline, clarify the direction and take measures in time, so as to win the opportunity of emergency repair and rapid emergency disposal.

If the construction of high-pressure pipeline area is involved, the operation unit can get prompt and contact information in time. Avoid high-pressure pipelines, and avoid pipeline damage caused by blind excavation, crossing and bumping of high-pressure pipelines, and geophysical damage, so as to achieve the purpose of maintaining gas supply safety.

There are two situations when setting the gas marker post. One is that it can be installed above the pipeline, which is installed directly above the pipeline. When there is no installation condition directly above the pipeline, but it must be installed, it can be set in the roadside green belt that is relatively close. However, a pipeline route diagram shall be set on the marker post to indicate the specific location of the pipeline.

The installation spacing of marker posts shall be based on the principle of easy observation. Considering the economy and practicality, due to the good field vision and combined with the current actual application of enterprises, it is appropriate to take 50 ~ 80m as the height of marker posts. Considering the convenience of observation, it can be appropriately higher. In practical application, the marker posts at the neighborhood management can be appropriately lower without specific regulations, and each company will decide on its own according to the specific situation.

There are many contents on the marker post, which can be roughly divided into internal and external information. External information is the fundamental purpose of the marker post setting, so it must include the name of the pipeline ownership unit, warning words and contact number. Informing the name and contact number of the pipeline ownership unit can facilitate other construction enterprises to contact during construction or citizens to notify the pipeline ownership unit in time in case of accidents. Warning words can include "no excavation under gas pipelines", "everyone is responsible for protecting pipelines", etc., which plays a role of warning and publicity. The information, including marker posts, pipeline area names, enterprise logos, etc., is controlled by the enterprise itself and is not strictly required.

The color selection of gas marker post is based on the following considerations. First, it should be clear and easy to observe. Secondly, in the selection of color, it should highlight the marker post of gas industry, which is different from that of other industries. The content of the sign should be clear and should be painted once every two years.
