玻璃钢管的特点和安装方法

Characteristics and installation method of FRP

下面为您介绍下关于玻璃钢管的特点和安装方法。

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

现有地下管线探测设备主要以探测金属管线为主,而非金属管道探测仪器价格昂贵,因此玻璃钢管埋地后目前无法探测,其它后续施工单位在施工中极易挖伤、损坏管道。

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.

目前明装玻璃钢管通过在其表面制作0.5mm厚的富树脂层和紫外线吸收剂,来延缓老化时间。随着运行时间的推移,富树脂层和紫外线吸收剂会遭到破坏,从而影响其使用寿命。

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.

覆土深度要求较高。目前尚未见到有关全国大型水司大规模使用玻璃钢管的报道,而由于玻璃钢管是新型管材,故使用寿命到底如何尚不得而知。由于玻璃钢的主要原材料选用高分子成分的不饱和聚脂树脂和玻璃纤维组成,能有效抵抗酸、碱、盐等介质的腐蚀和未经处理的生活污水、腐蚀性土壤、化工废水以及众多化学液体的侵蚀,在一般情况下,能够长期保持管道的安全运行。玻璃钢管水力条件好。内壁光滑、输送能力强,不结垢、不生锈、水阻小。玻璃钢管不但重量轻、强度高、可塑性强、运输与安装方便,还容易安装各种分支管,且安装技术简单。抗老化性能和耐热性能好。长期用于露天使用的管道,其外表面添加有紫外线吸收剂,来消除紫外线对管道的辐射,延缓玻璃钢管道的老化。

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.
