Briefly describe the advantages of prestressed plastic corrugated pipe equipment
Briefly describe the advantages of prestressed plastic corrugated pipe equipmentCompared with metal bellows equipment, prestressed plastic bellows equipment has the following advantages:
1. The raw material of the prestressed plastic corrugated pipe equipment is high-density polyethylene. Its corrosion resistance is far better than that of metal. Not afraid of acid and alkali corrosion. It does not corrode itself and can effectively protect the prestressed tendons from corrosion. Many prestressed structures have serious external effects, such as deicing salt or brine. When the post-tensioned member is blocked or fails due to the collapse of the waterproof layer, the leakage of micro-cracks, the drainage facilities, etc., the pre-stressed tendons may be corroded. The "prestressed tendon grouting" in the "FIP Construction Guide" points out that metal pipes have no permanent anti-corrosion ability, which is insufficient to resist water leakage and meet the requirements of paste and prestressed tendons. The prestressed plastic corrugated pipe equipment can provide better barrier protection to the prestressed tendons than the metal corrugated pipe equipment, and prevent harmful substances from penetrating into the pipeline, thereby ensuring the durability of the post-tensioned prestressed structure.

2. Under the same conditions, the friction coefficient of the prestressed plastic corrugated pipe equipment is significantly lower than that of the metal corrugated pipe equipment, thereby reducing the friction loss of the prestressing force during the stretching process. The coefficient of friction of prestressed plastic bellows equipment is generally 0.14, and that of metal bellows equipment is generally 0.25. The pre-stressed plastic corrugated pipe equipment has high strength, is not afraid of being stepped on, is not easy to be tampered with and destroyed, its sealing and anti-leakage are higher than that of the metal corrugated pipe equipment, and it is more suitable for vacuum grouting.
3. The prestressed plastic corrugated pipe equipment is non-conductive and can prevent stray current corrosion. Metal is a good conductor of electricity.
4. Prestressed prestressed plastic bellows equipment has good fatigue resistance, which can greatly improve the fatigue resistance of components.
