The main raw material for the production of warning tapes is PE raw particles. During the selection process, corresponding materials should be selected according to the technical requirements of the oil and natural gas industry for warning tapes. The raw materials should be pure and free of other impurities, otherwise it will affect the tensile and tear strength of the warning tape. Before production, in order to increase the horizontal and vertical stretching requirements of the warning tape, a certain proportion of linear materials are generally added, which cannot be too much or too little. If there is more cost, it will be added, but if there is less, the strength will be insufficient.

在地埋燃气管道的管顶上方0.30.5米处设置警示带，其作用为：当开挖施工时，如挖到警示带，则表示在下方0.30.5米处有燃气管道，起到了警示和保护作用。示踪作用。寻找地埋燃气管道时，找到警示带即找到了管道。起到了示踪作用。现在的警示带有示踪线， 利用测试仪器在不开挖的情况下，准确为管道定位。

A warning tape is set up 0.3 to 0.5 meters above the top of the buried gas pipeline. Its function is to indicate that there is a gas pipeline 0.3 to 0.5 meters below it during excavation construction, providing warning and protection. Tracing effect. When searching for buried gas pipelines, find the warning tape and you will find the pipeline. It has played a tracer role. The current warning comes with a tracer line, which uses testing instruments to accurately locate the pipeline without excavation.

1、产品介绍：警示带就是具有警示作用的带子。材质是锦纶的,具有良好的绝缘、耐燃、耐寒、耐电压、耐酸碱、耐溶剂等特性。它耐磨、耐腐蚀、耐油性佳，用于地面警告区域标示，颜色有红、黄、蓝、绿、白、黑、黄与黑、绿与白、红与白供参考，适应不同的需求。

1. Product introduction: Safety warning tape is a belt with a warning effect. The material is made of nylon, which has good insulation, flame resistance, cold resistance, voltage resistance, acid and alkali resistance, solvent resistance, and other characteristics. It has excellent wear resistance, corrosion resistance, and oil resistance, and is used for marking ground warning areas. The colors include red, yellow, blue, green, white, black, yellow and black, green and white, and red and white for reference, adapting to different needs.

2、警示带也还可以分为一次性警示带和重复使用警示带，以涤纶布为原材料的警示带，有效克服了一次性警示带使用周期短的局限性，不易拉断、易清洗的简包装方式，集中聚合了盒装警示带的优势，同时，又将盒装的局限性予以改良。简包装的方式，同时也使得警示带的长度更容易施展，连接更为容易和方便，使用的地域因此可无限扩大。

2. Safety warning tapes can also be divided into disposable warning tapes and reusable safety warning tapes. Safety warning tapes made of polyester fabric effectively overcome the limitations of a short service life of disposable safety warning tapes, as well as the simple packaging method that is not easy to break and clean. They concentrate on the advantages of boxed warning tapes, while also improving the limitations of boxed ones. The simple packaging method also makes the length of the warning tape easier to extend, the connection easier and more convenient, and the area of use can be infinitely expanded.
