Why do prestressed corrugated pipes have corrugations?

Whether it's a metal prestressed corrugated pipe or a non-metal prestressed corrugated pipe, they share a common feature: they provide compensation for equipment piping. To put it more intuitively, equipment piping will experience displacement under conditions such as operation vibration, high temperature, and movement. After installing a metal prestressed corrugated pipe on the equipment piping, the displacement of the pipe is absorbed by the corrugations of the prestressed corrugated pipe, effectively preventing the normal operation of the equipment piping from being affected by movement.

Metal prestressed corrugated pipes are a common compensating element in the pipelines of modern industrial equipment. Without a doubt, their role is to compensate, but many are unclear about what this "compensation" entails. In fact, it's quite straightforward. When pipelines undergo displacement, the main body of the corrugated prestressed pipe has the ability to stretch and deform, compensating for the pipeline's displacement and ensuring its healthy operation. Of course, in many modern industrial applications, these pipes are also used for noise reduction and vibration damping.

Pre-stressed corrugated pipes are essential materials used in post-tensioned prestressed concrete structures, and they are products developed by our company based on domestic and international data, in collaboration with various universities. Their features include innovative construction techniques, rapid speed, short cycles, and high quality. They offer advantages such as pressure resistance, anti-permeability, and good flexibility, making them widely used in various large and medium-sized bridges, high-rise long-span buildings, and functional architectural projects with curved or arched designs.

The processing technology for metal prestressed corrugated pipes involves the machining of corrugated pipe machines, creating wave-shaped ends that interlock, forming a spiral pattern to achieve the corrugated shape. In fact, as a branch of the prestressed corrugated pipe family, there are many types of corrugated prestressed pipes, generally categorized by their displacement method into angular prestressed corrugated pipes, axial prestressed corrugated pipes, and lateral prestressed corrugated pipes.
