The introduction of new technologies such as 3D printing has also made the design of bellows more flexible, capable of meeting the needs of different projects.

When the bellows are bent into different shapes, the instability of the bending angle can cause the bending angle of the bellows to change constantly. This unstable bending can cause the bellows to be repeatedly stressed during operation, which can cause cracks at the edge of the bellows, ultimately leading to damage to the bellows. The appearance of cracks not only affects the sealing of the fluid, but also can cause leakage, affecting the normal operation of the equipment. Damaged bellows need to be frequently replaced, increasing maintenance costs and downtime, and cannot meet the actual needs. SUMMARY

[0023] The multi-ribbed spiral corrugated pipe disclosed in this utility model mainly addresses some significant defects in existing corrugated pipes during use. When the corrugated pipe is bent into different shapes, the instability of the bending angle causes the bending angle of the corrugated pipe to change continuously. This unstable bending will subject the corrugated pipe to repeated stress during operation, which may lead to cracks at the edge of the corrugated pipe, eventually resulting in damage to the corrugated pipe. The appearance of cracks not only affects the sealing of the fluid, but may also cause leakage, affecting the normal operation of the equipment. Damaged corrugated pipes need to be replaced frequently, increasing maintenance costs and downtime.
