Product Description

Pre - stressed plastic corrugated pipe is made of HDPE as the raw material. It is mainly used for the hole - forming of tie - bars in post - tensioned prestressed cement structures. It has the advantages of good sealing performance, no water or grout seepage, high ring stiffness, small friction coefficient, aging resistance, anti - electrical erosion, good flexibility and elasticity, and is not easy to be chiseled by vibrating rods. Besides, the new connection method makes the construction connection more convenient.
Corrugated metal ducts for prestressed concrete are usually made of galvanized or non - galvanized low - carbon steel strips by spiral folding and locking. The surface is corrugated, which is used as the reserved duct in post - tensioned prestressed concrete structures or components. It has the advantages of being resistant to acid and alkali corrosion, good sealing, no seepage, high strength, and good flexibility.

Both prestressed plastic and metal bellows are widely used in prestressed concrete structures of bridges. They can form prestressed tendons to apply prestress to the concrete, improving the overall load - bearing capacity and durability of the bridge. Meanwhile, they can also be used in the bridge drainage system to prevent the bridge from being damaged by water accumulation.
In tunnel construction, Prestressed Bellows can be used for the drainage system and reinforcement structure. The plastic ones, with excellent impermeability, can be used as the waterproof layer of the tunnel lining to prevent groundwater seepage. Both types can resist the internal pressure changes of the tunnel, prevent the tunnel from being damaged due to deformation, and improve the safety and stability of the tunnel.
Prestressed bellows can be used for the reinforcement and support of building components, improving the load - bearing capacity and seismic performance of buildings. They can also be applied to the building drainage system to avoid damage caused by water accumulation.
In water conservancy projects, such as reservoirs and dikes, prestressed bellows can be used as impermeable walls to prevent reservoir seepage and dike breaches. They can also be used in canal linings and water - delivery pipelines to improve the overall performance and service life of water conservancy structures.
Prestressed plastic corrugated pipes can also be used in marine engineering for the construction of submarine pipelines and tunnels, in environmental protection projects for the impermeable treatment of landfills and sewage treatment plants, and in mine engineering for the reinforcement of mine roadways and mining areas. Prestressed metal bellows are also widely used in automatic control and measuring instruments, vacuum technology, mechanical industry, power industry, and other fields.
