With the development of the times, all walks of life have their own room for improvement, and there are more and more things available for us. I believe that everyone has seen corrugated pipes and has a simple understanding of it. I believe that the plastic corrugated hoses we have seen most should be the plastic corrugated hoses. So what is the development trend of plastic corrugated hose technology? Let us find out.

The plastic in the plastic corrugated hose is a new type of pore-forming material. Compared with the metal corrugated pipe, it has the following advantages: The raw material of the plastic corrugated pipe is HDPE. Its corrosion resistance is far better than that of metal, and it is not afraid of acid and alkali corrosion. It does not corrode itself and can effectively protect the prestressed tendons from corrosion. Many prestressed structures are subject to severe external influences, such as deicing salt or salt water. When the post-tensioned member collapses or fails due to the collapse of the waterproof layer, the leakage of micro-cracks, and the blockage or failure of the drainage facilities, the pre-stressed tendons may be corroded. It is not enough to resist water leakage and reach the slurry and prestressed tendons. The plastic corrugated pipe can provide a barrier protection for the prestressed tendons that is far superior to that of the metal corrugated pipe, and can prevent harmful substances from penetrating the pipeline from pollution, thereby ensuring that the post-tensioned prestressed structure has better durability; equal Under the conditions, the friction coefficient of the reserved pores of SBG(B) plastic wave tube is obviously smaller than that of the reserved pores of metal bellows, which reduces the friction loss of prestress during the tensioning process.

Generally, the coefficient of friction of plastic bellows is 0.14, while that of metal bellows is 0.25; plastic bellows have high strength, are not afraid of stepping on pressure, are not easy to be smashed by vibrating, and have high sealing performance and anti-leakage performance. For metal bellows, it is more suitable for vacuum grouting; plastic bellows are not conductive and can prevent stray current corrosion, while metal is a good conductor of electricity; plastic bellows have better labor resistance and can greatly improve the fatigue resistance of components .

The use of plastic corrugated hose is very extensive, and its use has brought us great convenience. As for more knowledge, I will introduce it to you in the future.
