• High Tensile Strength: Engineered to withstand pressures up to 20,000 psi, reducing the risk of deformation during expansion.
• Precision Engineering: CNC‑machined tolerances guarantee consistent expansion results and seamless fit with pipe and tube specifications.
• Long Service Life: Low maintenance design minimizes downtime and replacement costs.
• Versatile Compatibility: Compatible with a broad spectrum of large‑diameter pipelines, including oil & gas, petrochemical, and aerospace applications.

Technical Specifications

Typical Applications

This mandrel series is the ideal solution for:

• Pipeline expansion and repair in offshore and onshore oil & gas fields
• Aerospace tubing and structural component expansion
• Industrial heat‑exchanger tube enlargement
• Marine and desalination plant pipework
• Custom fabrication projects requiring precise, high‑pressure expansion

Installation & Usage Tips

1. Verify the pipe or tube diameter and wall thickness before selecting the appropriate mandrel size.
2. Ensure the expansion equipment is calibrated to the required pressure setting.
3. Apply a compatible, high‑temperature lubricant to reduce friction and extend mandrel life.
4. Monitor expansion pressure continuously to avoid over‑expansion and material fatigue.
5. After the expansion cycle, inspect the mandrel for any signs of wear before reuse.
