The prestressed corrugated pipe is made of HDPE, its corrosion resistance is far superior to that of metal, it is not afraid of acid and alkali corrosion, and it can protect the prestressed tendons from corrosion. Many prestressed structures are subjected to severe external influences, such as deicing salt or salt water. Prestressed tendons may be subject to corrosion when the post-tensioned member is subject to corrosion due to the collapse of the waterproof layer, the leakage of micro-cracks and the blockage or failure of the drainage facilities. The prestressed plastic bellows can provide a barrier protection far superior to the metal bellows for the prestressed tendons, and can prevent the pollution of harmful substances from penetrating the pipeline, thereby ensuring the good durability of the post-tensioned prestressed structure.

Application fields of prestressed plastic bellows:
1. Municipal engineering. Can be used for drainage and sewage pipes.
2. Construction engineering. Used for building rainwater pipes, underground drainage pipes, sewage pipes, ventilation pipes, etc.
3. Electrical and telecommunication engineering. Can be used as a protective tube for various power cables.
4. Railway and highway communications. It is used as a protective tube for communication cables and optical cables.
5. Industry. Widely used in sewage pipes in chemical, pharmaceutical and other industries.
6. Agriculture and garden engineering. It is used for irrigation and drainage of farmland, orchard, tea garden and forest belt.
7. Road works. Used as seepage and drainage pipes for railways and highways.
8. Mine. PVC double-wall corrugated pipes can be used as mine ventilation, water supply and drainage pipes.
