為保證示蹤線的導(dǎo)電性、強度、耐腐蝕和耐久性，要怎么對其進行有效的測試呢？接下來燃?xì)馐聚櫨€廠家就來講講這里的相關(guān)事項。

In order to ensure the conductivity, strength, corrosion resistance and durability of the trace wire, how to effectively test it? Next, the gas pipeline trace line manufacturer will talk about the relevant matters here.

燃?xì)馐聚櫨€是專為查找與定位地下非金屬管線而設(shè)計的產(chǎn)品，它有效地了非金屬管線不能用金屬管線尋管儀探查的問題，可廣泛適用于燃?xì)狻⒐┧芫€管線及排水管線等地下非金屬管網(wǎng)的查找與定位。

Gas tracing line is a product specially designed for locating and locating underground non-metallic pipelines. It effectively solves the problem that non-metallic pipelines cannot be detected with metal pipeline finder, and can be widely used for locating and locating underground non-metallic pipelines such as gas, water supply pipelines and drainage pipelines.

示蹤線探測，管道敷設(shè)完成后，應(yīng)使用管道探測器對已敷設(shè)之可探示蹤線進行可探性測試，以確保金屬絲已連接妥當(dāng)，應(yīng)記錄測試結(jié)果。

Tracer line detection: After the pipeline is laid, the pipeline detector shall be used to test the detectability of the laid tracers to ensure that the metal wires have been connected properly, and the test results shall be recorded.

將示蹤線的金屬線與管道定位儀的發(fā)射機輸入端連接，而發(fā)射機接地端應(yīng)且盡可能遠離發(fā)射機，使用接地樁或者電線桿的接地，以減少接地電阻。用接收器去探測接受發(fā)射信號。可以找到管道位移量和埋深。

Connect the metal wire of the tracer wire with the transmitter input end of the pipe locator, and the transmitter grounding end should be as far away from the transmitter as possible. Use the grounding pile or pole grounding to reduce the grounding resistance. Use the receiver to detect and receive the transmitted signal. The displacement and buried depth of the pipeline can be found.

一般宜選擇截面積大于2.5毫米的多股銅質(zhì)電線，鋪設(shè)時盡量讓示蹤線保持在管道的頂部位置，在三通等分支處應(yīng)將導(dǎo)線接頭的絕緣層剝掉，把銅芯絞在一起數(shù)圈，然后用絕緣膠布裹好接頭，以保持良好的導(dǎo)電性；

Generally, multi strand copper wires with a sectional area of more than 2.5 mm should be selected. When laying, the trace wire should be kept at the top of the pipe as much as possible. At the tee branch, the insulation layer of the wire joint should be stripped off, the copper core twisted together for several turns, and then the joint should be wrapped with insulating tape to maintain good conductivity;

示蹤線應(yīng)留有一定的線頭余量，并避免導(dǎo)線頭被泥土或雜物覆蓋，為減少無法出地的示蹤線末端的接地電阻，需采取剝掉絕緣層裸露芯線30cm的良好接地措施，對于采取定向鉆方式鋪設(shè)的PE管道，應(yīng)選用強度更大的導(dǎo)線，以避免在施工中被拉斷,導(dǎo)致無法探測定位；

A certain amount of wire head allowance shall be reserved for the trace wire, and the wire head shall not be covered by soil or sundries. In order to reduce the grounding resistance of the end of the trace wire that cannot go out of the ground, it is necessary to take good grounding measures to strip the insulation layer to expose the core wire for 30cm. For the PE pipe laid by directional drilling, the wire with greater strength shall be selected to avoid being pulled off during construction, resulting in the inability to detect and locate;

當(dāng)導(dǎo)線直徑遠小于埋深并忽略地介質(zhì)和空氣的介質(zhì)變化時，示蹤線可視為均勻介質(zhì)中的一條無限。更多相關(guān)事項可以隨時來我們網(wǎng)站http://www.xqpxqpp.cn咨詢了解！

When the diameter of the conductor is far less than the buried depth and the medium change of the ground medium and air is ignored, the trace line can be regarded as an infinite line in the uniform medium. More related matters can come to our website at any time http://www.xqpxqpp.cn Ask about it!
