决议供水警示带质量的要害因素是什么?

泉源:/ 宣布时间:日期:2022-07-01 0
作为埋地石油、自然气管道不可缺氨赡警示产品,警示胶带在应用中多年未曾替换。正是由于其优良的产品特征,警示胶带接纳PE(聚乙烯)颗粒制成,以是其防腐性能好,能包管埋地30-50年不腐败,将继续起到警示作用。那么决议警示胶带质量的要害因素有哪些?下面来简朴诠释一下吧。
As an indispensable safety warning product for buried oil and gas pipelines, warning tapes have not been replaced for many years. Because of its excellent product characteristics, the warning tape is made of PE (polyethylene) particles, so its anti-corrosion performance is good, which can ensure that it will not rot for 30-50 years, and will continue to play a warning role. So what are the key factors that determine the quality of warning tape? Let's explain briefly.
现在地下管道越来越多,交纵越来也越多,一些老旧的管道依然在运行并没有被放弃,但若是没有一款好的警示带用来看成 ;,而是选用了低档的质料产品,那么在管道没有老化之前它自己就先被剖析了,那就没有任何 ;ち,以是现在的警示带基本都接纳不降解的PE质料。
Now there are more and more underground pipelines, and there are more and more vertical pipelines. Some old pipelines are still running and have not been abandoned. But if there is no good warning tape for protection, but low-grade material products are selected, then the pipeline itself will be decomposed before it is aged, so there will be no protection. So now the warning tape basically uses non degradable PE materials.
供水警示带的原质料具有优异的PE(聚乙烯)颗粒性能。无味、、手感如蜡、耐低温性优良(很低事情温度可达-100~-70℃),在-60℃仍能坚持优异的机械性能,事情温度为80~110°C ;裙绦院,耐大大都酸碱侵蚀(不耐酸具有氧化性)。常温下不溶于一样平常溶剂,吸水率低,电绝缘性优良。经由测试,埋在地下30年,不会腐败。
The raw material of water supply warning tape has good PE (polyethylene) particle performance. It is tasteless, non-toxic, feels like wax, and has excellent low temperature resistance (the working temperature can reach -100~-70 ℃ at a very low temperature). It can still maintain good mechanical properties at -60 ℃, and the working temperature is 80~110 ° C. Good chemical stability, resistant to most acid and alkali erosion (acid intolerance and oxidation). It is insoluble in general solvents at room temperature, with low water absorption and excellent electrical insulation. After testing, it will not rot after being buried underground for 30 years.

另一个是历程。大部分吹膜装备是很新的三层共挤装备,可以包管警示带半制品的横向和纵向撕裂强度,可以有用控制产品的厚度和宽度凭证手艺文件,超标会增添本钱。然后是印刷历程,若是再都的警示带没有抓好,管道埋在地下3-5年就会褪色,就不可起到警示作用。
The other is the process. Most of the film blowing equipment are very new three-layer coextrusion equipment, which can ensure the transverse and longitudinal tear strength of the semi-finished warning tape, and can effectively control the thickness and width of the product. According to the technical documents, exceeding the standard will increase the cost. Then there is the printing process. If the warning tape of zaidu is not grasped well, the pipeline will fade after being buried underground for 3-5 years, so it cannot serve as a warning.
别的在管道埋地施工历程中,施工职员将警示带与管道同向铺设在上方30-50cm处,具有很好的警示提醒作用,这就很洪流平阻止了其它在周围施工时无意损坏管道,选成管道防腐层破损,更严重的还会造成管道泄露。为避免管道运行泛起危害,现在施工设计部分都将此产品列入了施工手艺规范。
In addition, during the buried construction of the pipeline, the construction personnel will lay the warning tape in the same direction with the pipeline at the upper 30-50cm, which has a good warning effect, which largely avoids other unintentional damage to the pipeline during nearby construction, such as the damage of the pipeline anti-corrosion coating, and even more serious, the leakage of the pipeline. In order to prevent the risk of pipeline operation safety, the construction design department has now included this product in the construction technical specifications.
