Laying overhead heating pipes sometimes must be laid over main roads, and natural topography, like valleys, rivers, lakse or subsidence aresa. When more than 100m, the installation method generally used is the suspension pipe rack system combined with rotary compensation technology. This is the only way to solve this engineering problem .
