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.

在地埋燃氣管道的管頂上方0.30.5米處設置警示帶，其作用為：當開挖施工時，如挖到警示帶，則表示在下方0.30.5米處有燃氣管道，起到了警示和保護作用。示蹤作用。尋找地埋燃氣管道時，找到警示帶即找到了管道。起到了示蹤作用。現在的警示帶有示蹤線， 利用測試儀器在不開挖的情況下，準確為管道定位。

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、產品介紹：警示帶就是具有警示作用的帶子。材質是錦綸的,具有良好的絕緣、耐燃、耐寒、耐電壓、耐酸堿、耐溶劑等特性。它耐磨、耐腐蝕、耐油性佳，用于地面警告區域標示，顏色有紅、黃、藍、綠、白、黑、黃與黑、綠與白、紅與白供參考，適應不同的需求。

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、警示帶也還可以分為一次性警示帶和重復使用警示帶，以滌綸布為原材料的警示帶，有效克服了一次性警示帶使用周期短的局限性，不易拉斷、易清洗的簡包裝方式，集中聚合了盒裝警示帶的優勢，同時，又將盒裝的局限性予以改良。簡包裝的方式，同時也使得警示帶的長度更容易施展，連接更為容易和方便，使用的地域因此可無限擴大。

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.
