HydroPro's Standard Tooling offers the abiilty to expand tubes at extremely high pressures, across a hug range of sizes. To date HydroPro has manufactured tooling for applications having a 4mm ID up to a 203mm ID.
The secret? Our proprietary dual cam/segment assembly. During expansion, the segments remain parallel to the axis of the tube, minimizing bending stress. The result is greater strength, longer life, less leakage, and reduced tube marking when compared to competitve products. The segment assemblies act to hold the mandrel in the center of the tube, and support the sealing components of the tool, allowing for sustained high pressure expansion.
- Expansion of a wider tube I.D. variation jumps traditional size gaps.
- Fast and easy band and segment replacement increases efficiency and ease of use.
- Standard sizes for tubes from 3/16" - 8" ID (non-standard sizes available upon request)
When in a relaxed (static) state, the beveled cams fit snugly against the segment assemblies. Since there is no force applied, the segments remain firmly in place.
Once hydraulic pressure is applied to the mandrel, the beveled cams are forced toward each other. As the cams move, the individual segments are forced symmetrically outward, held together by the band.
