警示带作为埋地石油、天然气管道不可或缺的警示产品，在应用数年来一直没有被替代正是因为它非常好的产品特性，警示带以PE（聚乙烯）颗粒为原料，所以它的防腐性能好，可保障埋地30-50年不被分解持续起到警示作用，那决定燃气警示带质量的关键因素到底有哪些，下面就为大家讲解一下。

As an indispensable safety warning product for buried oil and gas pipelines, the warning tape has not been replaced for several years because of its very good 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 be decomposed for 30-50 years. What are the key factors that determine the quality of the gas warning tape.

先要讲的是警示带的原料PE（聚乙烯）颗粒的性能好，它无臭，，手感似蜡，具有优良的耐低温性能（低使用温度可达-100~-70°C），在-60℃下仍可保持良好的力学性能，使用温度在80~110℃。化学稳定性好，能耐大多数酸碱的侵蚀（不耐具有氧化性质的酸）。常温下不溶于一般溶剂，吸水性小，电绝缘性优良，经测试埋入地下30年不会腐烂。

The first thing to say is that the raw material PE (polyethylene) particle of the warning tape has good performance. It is odorless, non-toxic, feels like wax, and has excellent low temperature resistance (low service temperature can reach - 100~- 70 ° C). It can still maintain good mechanical properties at - 60 ℃, and the service temperature is 80~110 ℃. It has good chemical stability and can resist the corrosion of most acids and alkalis (not resistant to acids with oxidizing properties). It is insoluble in general solvents at room temperature, has low water absorption, excellent electrical insulation, and will not rot after being buried underground for 30 years.

再者就是工艺，我厂的吹膜设备均为三层共挤新设备，能保障警示带半成品的横向和纵向的抗撕裂强度，同时可根据技术文件有效的控制产品的厚度和宽度，不会因为超标而造成成本提高。

Moreover, the process. All the film blowing equipment in our factory are new three-layer coextrusion equipment, which can ensure the horizontal and vertical tear resistance of the warning tape semi-finished products. At the same time, the thickness and width of the products can be effectively controlled according to the technical documents, and the cost will not be increased because of exceeding the standard.

然后就是印刷工艺，再都的警示带如果警示语印刷工艺把握不好，随管道埋入地下3-5年便褪色了，那就起不到警示作用了。

Then there is the printing process. If the printing process of the warning tape in Zaidau is not well understood, it will fade after being buried in the ground for 3-5 years, which will not serve as a warning.

看完上述三条关键因素，大家在采购警示带时也有了技术考核标准了，感谢大家的阅读，本公司成立多年以来为我国多条众点管线提供了警示带，得到了客户的高度认可。您有相关的需要就来我们网站http://www.binzhouhengtong.com进行咨询了解吧！
