The Haenke Closed Pitch Flexible Metal Tube is manufactured with more links (corrugation) per inch, which allows it to achieve greater flexibility compared to normal pitch pipes. This corrugation, known as closed pitch, has a smaller minimum bending radius and longer service life in bending cycles, making it ideal for more severe applications where flexibility and resistance to bending cycles are important requirements.
Features and Benefits
Greater Flexibility: Designed with more links per inch to provide greater flexibility compared to standard pitch tubes.
Resistance to Bending Cycles: Features a longer service life to bending cycles, ensuring durability in severe industrial applications.
Low Minimum Radius of Curvature: The closed step allows you to achieve a smaller minimum radius of curvature, expanding its application possibilities.
Versatility: Suitable for applications where flexibility and resistance to bending cycles are essential,such as exhaust systems, industrial equipment and much more.
