警示帶敷設前應對敷設面壓實，然后將其平整的敷設在管道的正上方，距管頂的距離宜為0.3~0.5米，但不得埋入路基和路面里。

Before laying the warning tape, the laying surface should be compacted, and then it should be laid flat directly above the pipeline. The distance from the top of the pipeline should be 0.3-0.5 meters, but it should not be buried in the roadbed and road surface.

警示帶的內容必須包括：設備權屬單位名稱、危險標記、警示用語、聯系電話、設計壓力等級。

The content of the warning tape must include: the name of the equipment ownership unit, danger signs, warning language, contact phone number, and design pressure level.

示蹤線

Tracer line

聚乙烯燃氣管道敷設時，應在管頂同時隨管道走向敷設示蹤線。示蹤線宜采用2×2.5mm2 雙線單芯銅線，外有絕緣良好的保護層。示蹤線應有效連接，在銅線接頭處宜采用雙線纏繞錫焊工藝，保證導電性能。外絕緣處用膠帶包扎，并用熱收縮套封固，封固腸肚必須大于膠帶包扎端20mm.沿聚乙烯燃氣管道走向每隔2km應設信號源井。檢查井等設施可作為信號源井。信號源井內又信號接頭，用于接駁示蹤線的測試外接信號。 電子標識器  燃氣管道宜設置電子標識器。電子標識器內存可包括管道權屬單位名稱、管道口徑、安裝或維修日期、壓力級制、 施工單位名稱、電子標識器與管道的相對位置等。

When laying polyethylene gas pipelines, tracer lines should be laid at the top of the pipeline along with the direction of the pipeline. The tracer line should use 2 × 2.5mm2 double wire single core copper wire with a well insulated protective layer on the outside. The tracer wire should be effectively connected, and the double wire winding soldering process should be used at the copper wire joint to ensure conductivity. Wrap the external insulation with tape and seal it with a heat shrink sleeve. The sealing end must be 20mm larger than the tape wrapping end. Signal source wells should be installed every 2km along the direction of the polyethylene gas pipeline. Inspection wells and other facilities can serve as signal source wells. There is a signal connector inside the signal source well, which is used to connect external signals for testing tracer lines. Electronic markers should be installed on gas pipelines. The memory of the electronic identifier can include the name of the pipeline ownership unit, pipeline diameter, installation or maintenance date, pressure rating system, name of the construction unit, and the relative position of the electronic identifier with the pipeline.

電子標識器應安裝在以下位置：

Electronic markers should be installed in the following locations:

閥門、水井、犧牲陽極等管道附屬設施點。

Valves, water wells, sacrificial anodes, and other pipeline ancillary facilities.

管道轉彎處、管道三通、四通處。

At pipe bends, tees, and tees.

其他人為重要而需要標注的位置。

Other important positions that need to be marked.

無上述安裝點的地下燃氣管道的直線段電子標識器埋設間距應為100米。  維護管理

The buried spacing of electronic markers for straight sections of underground gas pipelines without the above installation points should be 100 meters. maintenance management

標識應分類編號并登記入檔。

The identification should be classified, numbered, and registered in the file.

新建管道及設施標識應與主體工程同時設計、施工、驗收并交付使用。

The identification of newly constructed pipelines and facilities should be designed, constructed, inspected, and delivered for use simultaneously with the main project.

已建管道、設施及環境發生變化時，應及時增減或變更標識。

When there are changes in the existing pipelines, facilities, and environment, the identification should be promptly added, removed, or changed.

標識權屬單位應按管道巡檢周期同步巡查，保證標識完好。標識丟失、損壞時，應及時處置。

The identification ownership unit should conduct synchronous inspections according to the pipeline inspection cycle to ensure that the identification is intact. When the identification is lost or damaged, it should be disposed of in a timely manner.

標識內容應清晰。宜兩年刷漆一次。

The identification content should be clear. It is recommended to paint once every two years.

本規程用此說明

This regulation uses this explanation

為便于在執行本規程條文時區別對待，對要求嚴格程度不同的用此說明如下：

In order to facilitate differential treatment when implementing the provisions of this regulation, this explanation is used for those with different levels of strictness:

⑴  表示很嚴格，非這樣做不可的用詞： 正面詞采用“必須” 反面詞采用“嚴禁”。

(1) Words that indicate strictness and must not be used: positive words use "must" and negative words use "strictly prohibited".

⑵  表示嚴格，在正常情況下均這樣做的用詞：正面詞采用“應”反面詞采用“不應或“不得”

(2) Words that indicate strictness and should be used under normal circumstances: positive words use "should", negative words use "should not" or "should not"

⑶  表示允許稍有選擇，在條件許可時應這樣做的用詞：正面詞采用“宜”或“一般”反面詞采用“不宜”。表示有選擇，在一定條件下可以這樣做的，采用“可”。

(3) Words that allow for slight choices should be used first when conditions permit: positive words should be "appropriate" or "general", while negative words should be "inappropriate". It indicates that there is a choice and can be done under certain conditions, using "may".
