Comparison of prestressed plastic corrugated pipe equipment and metal corrugated pipe equipmentComparison of prestressed plastic corrugated pipe equipment and metal corrugated pipe equipment
The types of bellows are prestressed plastic bellows and metal bellows. Among them, the pre-stressed plastic corrugated pipe is popular because of its lower cost and greater operability. The equipment used to manufacture corrugated pipes is also pre-stressed plastic corrugated pipes and metal corrugated pipes. In terms of equipment, the following honest plastic compares the two equipment to see the differences between the two and their respective advantages.
Comparison of prestressed plastic corrugated pipe equipment and metal corrugated pipe equipment:
The prestressed plastic corrugated pipe is made of high-density polyethylene, and its corrosion resistance is much better than that of metal. When used, it has great advantages because it is not afraid of acid and alkali corrosion, will not corrode itself, and so on. Therefore, it can effectively protect the prestressed tendons from corrosion, and many prestressed structures are subject to severe external influences, such as deicing salt and salt water.
Compared with metal bellows equipment, prestressed plastic bellows equipment has no corrosion resistance. If used for a long time, it will inevitably lead to water penetration and corrosion. Metal bellows equipment is not enough to withstand water. For the leakage and arrival of mud and prestressed tendons, the prestressed plastic corrugated pipe can provide the prestressed tendons with a barrier protection far superior to that of the metal corrugated pipe. Therefore, the advantages of the prestressed plastic corrugated pipe equipment are more obvious.
In addition, the pre-stressed plastic corrugated pipe has high strength and is not afraid of being stepped on, and it is not easy to be damaged by vibration and compaction. Its sealing performance and leakage resistance are better than that of metal bellows, and it is more suitable for vacuum grouting.
Therefore, the single-wall corrugated pipe production line and the metal corrugated pipe equipment have different differences and advantages, but the prestressed plastic corrugated pipe has more advantages and its market demand is more extensive.
