燃气管道示踪线怎么举行有用测试

泉源:/ 宣布时间:日期:2022-10-18 0
为包管示踪线的导电性、强度、耐侵蚀和耐久性,要怎么对其举行有用的测试呢 ?接下来燃气示踪线厂家就来讲讲这里的相关事项。
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.
燃气示踪线是专为查找与定位地下非金属管线而设计的产品,它有用地了非金属管线不可用金属管线寻管仪探查的问题,可普遍适用于燃气、供水管线管线及排水管线等地下非金属管网的查找与定位。
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.
示踪线探测,管道敷设完成后,应使用管道探测器对已敷设之可探示踪线举行可探性测试,以确保金属丝已毗连稳当,应纪录测试效果。
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.
将示踪线的金属线与管道定位仪的发射机输入端毗连,而发射机接地端应且尽可能远离发射机,使用接地桩或者电线杆的接地,以镌汰接地电阻。用吸收器去探测接受发射信号 ?梢哉业焦艿牢灰屏亢吐裆。
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.

一样平常宜选择截面积大于2.5毫米的多股铜质电线,铺设时只管让示踪线坚持在管道的顶部位置,在三通中分支处应将导线讨论的绝缘层剥掉,把铜芯绞在一起数圈,然后用绝缘胶布裹好讨论,以坚持优异的导电性 ;
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;
示踪线应留有一定的线头余量,并阻止导线头被土壤或杂物笼罩,为镌汰无法出地的示踪线最后的接地电阻,需接纳剥掉绝缘层裸露芯线30cm的优异接境地伐,关于接纳定向钻方法铺设的PE管道,应选用强度更大的导线,以阻止在施工中被拉断,导致无法探测定位 ;
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;
当导线直径远小于埋深并忽略地介质和空气的介质转变时,示踪线可视为均勻介质中的一条无限。更多相关事项可以随时来我们网站咨询相识!
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 Ask about it!
