玻璃鋼管的特點和安裝方法

Characteristics and installation method of FRP

下面為您介紹下關于玻璃鋼管的特點和安裝方法。

The following is about the characteristics and installation method of FRP.

現有地下管線探測設備主要以探測金屬管線為主,而非金屬管道探測儀器價格昂貴,因此玻璃鋼管埋地后目前無法探測,其它后續施工單位在施工中極易挖傷、損壞管道。

The existing underground pipeline detection equipment is mainly used to detect the metal pipeline, but the non-metal pipeline detection instrument is expensive, so it is impossible to detect the buried GRP at present, and other subsequent construction units are very easy to dig and damage the pipeline in the construction.

目前明裝玻璃鋼管通過在其表面制作0.5mm厚的富樹脂層和紫外線吸收劑,來延緩老化時間。隨著運行時間的推移,富樹脂層和紫外線吸收劑會遭到破壞,從而影響其使用壽命。

At present, 0.5mm thick resin rich layer and ultraviolet absorber are made on the surface of surface mounted FRP pipe to delay the aging time. As the running time goes on, the resin rich layer and ultraviolet absorber will be damaged, which will affect its service life.

覆土深度要求較高。目前尚未見到有關全國大型水司大規模使用玻璃鋼管的報道,而由于玻璃鋼管是新型管材,故使用壽命到底如何尚不得而知。由于玻璃鋼的主要原材料選用高分子成分的不飽和聚脂樹脂和玻璃纖維組成,能有效抵抗酸、堿、鹽等介質的腐蝕和未經處理的生活污水、腐蝕性土壤、化工廢水以及眾多化學液體的侵蝕,在一般情況下,能夠長期保持管道的安全運行。玻璃鋼管水力條件好。內壁光滑、輸送能力強,不結垢、不生銹、水阻小。玻璃鋼管不但重量輕、強度高、可塑性強、運輸與安裝方便,還容易安裝各種分支管,且安裝技術簡單。抗老化性能和耐熱性能好。長期用于露天使用的管道,其外表面添加有紫外線吸收劑,來消除紫外線對管道的輻射,延緩玻璃鋼管道的老化。

The depth of covering soil is required to be higher. At present, there is no report about the large-scale use of glass fiber reinforced plastic pipes by large-scale water companies in China. As glass fiber reinforced plastic pipe is a new type of pipe, its service life is still unknown. As the main raw material of FRP is composed of unsaturated polyester resin and glass fiber, it can effectively resist the corrosion of acid, alkali, salt and other media, and the erosion of untreated domestic sewage, corrosive soil, chemical wastewater and many chemical liquids. In general, it can maintain the safe operation of the pipeline for a long time. The hydraulic condition of FRP is good. Smooth inner wall, strong conveying capacity, no scaling, no rust, small water resistance. FRP is not only light weight, high strength, strong plasticity, convenient transportation and installation, but also easy to install various branch pipes, and the installation technology is simple. It has good anti-aging and heat resistance. The outer surface of the pipeline which has been used in the open air for a long time is added with ultraviolet absorbent to eliminate the radiation of ultraviolet rays on the pipeline and delay the aging of FRP pipeline.
