Flexible metal hoses

Contact

Corrugated hoses are thin-walled, cylindrical components with a corrugated structure in their lateral area. The type of corrugation differentiates annularly corrugated hoses and coil corrugated hoses.

Stripwound hoses are produced in a continuous process by profiling and helical coiling of a cold-rolled metal strip on a mandrel.
