- Abstract:
- For a long time, steel pipe has been widely used in the construction of large-diameter river crossing and submerged pipes in China, but the high anti-corrosive construction requirements and the difficult control of weld anti-corrosion limits the service life of the pipeline, increases operation, maintenance costs and leakage risk. By analyzing and comparing the mechanical performance, corrosion resistance and electric corrosion resistance, comprehensive cost, and interface form, SIA Wb ductile iron pipe with internal self-anchor interface is selected as the pipe material for DN800 water supply sinking project in Yandai River in Wuxi. Three key points affecting the successful implementation of the project are summarized: the spacing of lifting points, the safety of interface structure, the effectiveness of rubber rings, and the reinforcement treatment of pipe elbows, which can provide reference for the implementation of similar projects in the future.
