It is necessary to install pipeline marker posts, gas marker posts, buried warning tapes, and warning sign blocks for the burial of general natural gas pipelines. Although the previous natural gas pipelines were buried, due to the large spacing and unclear markings, it was difficult to distinguish which natural gas pipeline was buried below, resulting in frequent incidents of natural gas pipeline excavation.

Natural gas has now become a necessity for people's lives, and its use is increasing. With the widespread use, there are more and more pipelines for transporting natural gas, many of which are complex and confusing, posing significant risks to pipeline protection and people's safety.

Natural gas started from the West–East Gas Pipeline. The West–East Gas Pipeline is one of the livelihood projects in the past decade. After the completion of the first and second line projects, only Yunnan, Fujian, Macao and Taiwan did not use natural gas. Only along the first and second line projects, 400 million people used natural gas sent from the west and abroad. Few projects can benefit so many people. In such a large project, there are many pipelines used. In order to ensure the safety of natural gas pipelines and the convenience of future construction, a sign is needed to distinguish them. This type of sign is a gas marker post, which is usually installed above the pipeline. A gas marker post needs to be buried at a distance of 50 meters, and it needs to be buried at the corner of the branch. Piles are generally marked with information such as gas pipelines, construction unit phone numbers, and pipeline routing.

Fiberglass gas marker posts not only have various advantages of traditional marker posts, but also complement the shortcomings of traditional marker posts. There are also many advantages that traditional marker posts do not have, such as high strength, lifelong protection, light weight, good tensile strength, corrosion resistance, long service life, easy installation and transportation, theft prevention, etc. Moreover, Fiberglass gas marker posts meet national environmental protection requirements and are accustomed to future development needs, And able to plan manufacturing according to customer requirements.
