如今錯綜復雜的地下管線維護，就成了不小的難題。今天，我們就來一起了解地埋警示帶選購的3個關鍵要點！

Nowadays, the maintenance of complicated underground pipelines has become a big problem. Today, we are going to learn about the three key points for the purchase of buried warning tape!

1、看材質

1. Look at the material

深埋地下的壓力管道，大多采用PE管道，這些管道普遍被應用于燃氣、水利等基礎設施建設之中。為了保護這些地下管道，減少在施工挖掘時被不慎挖斷的幾率，避免造成燃氣泄露、通訊中斷，乃人員受傷等嚴重后果，地埋警示帶應運而生。

Most of the buried pressure pipes are PE pipes, which are widely used in gas, water and other infrastructure construction. In order to protect these underground pipelines, reduce the chance of being accidentally cut during construction and excavation, and avoid serious consequences such as gas leakage, communication interruption, and even personal injury, buried warning tapes came into being.

我國目前實施的《城鎮燃氣標志標準》就要求，在中低壓天然氣管道安裝的工程中須緊貼管道位置，埋設可以探測的示蹤帶，從而方便施工方對管道進行探測和定位，在管道上方200-300mm處需要鋪設PE材質的保護板，避免挖掘設備開挖時管道受損。

The Standard for Urban Gas Signs currently implemented in China requires that the installation of medium and low pressure natural gas pipelines must be close to the pipeline location, and the tracers that can be detected must be buried, so as to facilitate the construction party to detect and locate the pipeline. The protective plate made of PE should be laid at 200-300mm above the pipeline to avoid damage to the pipeline during excavation of excavation equipment.

所以，選購地埋警示帶的時候，材質就是不容忽視的關鍵要點之一。地埋警示帶，就采用了PE管材級材質，這種材質常常被用于生產和制作管材，質地堅硬，耐酸堿腐蝕，使用壽命長，即便是長期埋在潮濕的土壤中也不會腐壞變質。

Therefore, when purchasing the buried warning tape, the material is one of the key points that cannot be ignored. The buried warning tape is made of PE pipe material, which is often used to produce and make pipes. It is hard, acid and alkali resistant, and has a long service life. It will not deteriorate even if it is buried in wet soil for a long time.

2、看厚度

2. See thickness

影響一塊地埋警示帶耐沖擊性能的，不僅僅取決于材質，還取決于板材的厚度。一些小廠家為了壓縮生產成本，就在板材的厚度上大做文章，生產出的地埋警示帶厚度不達標，這大大影響了地埋警示帶的使用。

The impact resistance of a buried warning tape depends not only on the material, but also on the thickness of the plate. In order to reduce the production cost, some small manufacturers made a big deal in the thickness of the plates, and the thickness of the buried warning tapes produced was not up to the standard, which greatly affected the safety of the buried warning tapes.

在地埋警示帶的厚度、規格上都精益求精，力求保障產品的性，比如材料密度達到0.9/cm3,尺寸穩定性在35%以下，整體厚度控制在3-5mm左右，這足以保證地埋警示帶抗沖擊性能更加優異，能夠對下方的管道形成足夠的防護作用。

The thickness and specification of the buried warning tape shall be improved to ensure the safety of the product. For example, the material density shall reach 0.9/cm3, the dimensional stability shall be less than 35%, and the overall thickness shall be controlled at about 3-5 mm, which is enough to ensure that the buried warning tape has better impact resistance and can form sufficient protection for the pipeline below.

3、看印刷質量

3. Look at the printing quality

地埋警示帶不僅需要安裝金屬示蹤線，還應當在表面印刷醒目的圖案和文字，提醒施工單位小心施工，盡量避免施工風險。由于地埋警示帶長期埋在潮濕悶熱的地下，一旦印刷質量不過關，就會給施工帶來不可預估的隱患。

The buried warning tape not only needs to be installed with metal trace lines, but also should be printed with striking patterns and words on the surface to remind the construction unit to be careful and avoid construction risks as much as possible. As the buried warning tape is buried in the damp and hot ground for a long time, once the printing quality is not up to standard, it will bring unpredictable potential safety hazards to the construction.

地埋警示帶的性上下足功夫，增添了一些輔助材料來提升整體的韌性和耐老化性能，表面印刷內容采用高溫覆膜技術，這能夠保證印刷的圖案和文字可以長久保持鮮艷、醒目，不容易脫落、掉色，影響警示性。

The safety of buried warning tape has been greatly improved. Some auxiliary materials have been added to improve the overall toughness and aging resistance. High temperature film covering technology is used for the surface printing content, which can ensure that the printed patterns and characters can remain bright and eye-catching for a long time, and are not easy to fall off and fade, affecting the warning.

地埋警示帶看似普通，但對地下管網來說，卻是一道關重要的防線。倘若您需要選購靠譜的地埋警示帶，可以按照以上3個關鍵要點來選擇。當然，如果想要節省選購時間、更加省心省事地搞定采購，那不妨來我們這里http://m.scnu-graduate.com看看！
