Tube Hydroforming

At Intran, we’re excited to have added tube hydroforming with bellows/corrugates to our extensive list of services. If you’re wondering what that is, you came to the right place. We hope to add other hydroforming options in the near future but at the present can only offer tube hydroforming with bellows/corrugates.

What is Tube Hydroforming?

Tube hydroforming is a technique used to create bellows that are frequently used by certain industries, like oil and gas, automotive, and aerospace. The end-product bellow/corrugated tubes are flexible, thin walled yet strong, and generally transport fluid or gas. Metal bellows are shaped through more than 400 KPA of fluid pressure and precision tooling. Using this high pressure fluid inside the tube, the process cycles until it reaches the correct bellow.

Just how thin or thick a bellow/corrugated wall is depends on how it will be used. Hydroforming is one of the best methods for ensuring consistent wall thickness and dimensional tolerances, which are imperative in mechanical applications. For instance, some bellows must fit in tight corners within an engine and withstand fluctuations in pressure, vibration and temperature while the vital fluid moves through them.
