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(biāo)識器應(yīng)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(shè)施點。

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

管道轉(zhuǎn)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(biāo)注的位置。

Other important positions that need to be marked.

無上述安裝點的地下燃?xì)夤艿赖闹本€段電子標(biāo)識器埋設(shè)間距應(yīng)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(biāo)識應(yīng)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(shè)施標(biāo)識應(yīng)與主體工程同時設(shè)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(shè)施及環(huán)境發(fā)生變化時，應(yīng)及時增減或變更標(biāo)識。

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

標(biāo)識權(quán)屬單位應(yīng)按管道巡檢周期同步巡查，保證標(biāo)識完好。標(biāo)識丟失、損壞時，應(yīng)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(biāo)識內(nèi)容應(yīng)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(guī)程用此說明

This regulation uses this explanation

為便于在執(zhí)行本規(guī)程條文時區(qū)別對待，對要求嚴(yán)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(yán)格，非這樣做不可的用詞： 正面詞采用“必須” 反面詞采用“嚴(yán)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(yán)格，在正常情況下均這樣做的用詞：正面詞采用“應(yīng)”反面詞采用“不應(yīng)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(yīng)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".
