燃?xì)馐聚櫨€(xiàn)廠(chǎng)家為您進(jìn)行講解。
The metal trace line laid along the gas buried PE pipe is intended to find the gas pipeline more conveniently in the future (it is an auxiliary means to find the pipeline more conveniently in the future). The manufacturer of gas trace line will explain it to you below.
1、金屬示蹤線(xiàn)安裝后隨管道埋地后,在驗(yàn)收時(shí)應(yīng)用地下管道探測(cè)儀(該儀器有點(diǎn)貴,但應(yīng)是燃?xì)庑袠I(yè)的應(yīng)配設(shè)施,特別是生產(chǎn)運(yùn)營(yíng)部門(mén))來(lái)檢驗(yàn)示蹤線(xiàn)的完整性,原理及實(shí)用方法十分簡(jiǎn)單。
1. After the metal trace line is installed and buried along with the pipeline, the underground pipeline detector (which is a little expensive, but should be a necessary facility in the gas industry, especially in the production and operation department) should be used to check the integrity of the trace line during acceptance. The principle and practical method are very simple.
2、在非開(kāi)挖工程中(定向鉆作業(yè)),為了保證示蹤線(xiàn)的完整性,示蹤線(xiàn)的規(guī)格通常采用40平方的單芯銅錢(qián),且要用雙線(xiàn),綁在將要拖入的燃?xì)釶E管上,在拖管時(shí)隨管一同拖入。
2. In the trenchless project (directional drilling operation), in order to ensure the integrity of the trace line, the specification of the trace line is usually 40 square single core copper coin, which is tied to the gas PE pipe to be pulled in with two lines, and is pulled in with the pipe.
3、因在查找管線(xiàn)用到示蹤線(xiàn)時(shí)是依靠閉合電路中的電流來(lái)進(jìn)行操作的,由于電阻問(wèn)題,電流強(qiáng)度用隨著檢測(cè)點(diǎn)與信號(hào)發(fā)射機(jī)的距離增加而減弱。
3. As the tracing line is used to find the pipeline, the operation depends on the current in the closed circuit. Due to the resistance problem, the current intensity decreases as the distance between the detection point and the signal transmitter increases.
一般來(lái)說(shuō),25平方的單芯銅線(xiàn)作示蹤線(xiàn),其發(fā)射機(jī)的信號(hào)有效范圍半徑為300米(示蹤線(xiàn)越好有效半徑越大)。示蹤線(xiàn)連續(xù)敷設(shè)檢測(cè)位置可直接設(shè)置在閥門(mén)井、凝水井內(nèi),如300米內(nèi)沒(méi)有閥門(mén)井或其他可以檢測(cè)示蹤線(xiàn)的位置,應(yīng)單獨(dú)設(shè)立示蹤線(xiàn)檢測(cè)井;檢測(cè)井應(yīng)在竣工圖上標(biāo)出,以方便以后使用。
Generally speaking, the 25 square square single core copper wire is used as the tracer wire, and the effective radius of the transmitter signal is 300 meters (the better the tracer wire is, the greater the effective radius is). The continuous laying detection position of the trace line can be directly set in the valve well and condensate well. If there is no valve well or other position where the trace line can be detected within 300 meters, the trace line detection well shall be set separately; The inspection well shall be marked on the as built drawing for future use.
示蹤線(xiàn)安裝不是技術(shù)含量太高的工作,要綁在燃?xì)夤艿郎?原則上是綁在正上方,因?yàn)樗€肩負(fù)著測(cè)管道埋深的任務(wù)),在接頭處要處理好,如使用專(zhuān)用接線(xiàn)套管。更多相關(guān)內(nèi)容就來(lái)我們網(wǎng)站進(jìn)行

The installation of the trace line is not a work with too high technical content. It should be tied to the gas pipeline (in principle, it should be tied directly above, because it is also responsible for measuring the buried depth of the pipeline). It should be handled well at the joints, such as using special wiring sleeves. More relevant content will come to our website http:// consulting service
