Cost-Effective Tube Repairs – Delivered On Time

Tube failures in critical process heat exchangers can be costly, disruptive, and dangerous. Unplanned outages drive up turnaround costs, delay production, and negatively impact profitability. Curran International provides cost-effective repair solutions to restore and extend the life of your tubular heat exchangers—without full unit replacement.

Tackling Tube Failure Challenges

Curran offers a wide array of alloy-based tube repair options, allowing clients to upgrade existing metallurgy in-situ. Instead of simply plugging tubes, Curran installs ferrules or full-length liners, preserving tube integrity during short maintenance outages.

This approach addresses the root causes of tube failure:

  • Localized corrosion
  • Accelerated erosion
  • Tube-to-tube-sheet joint failures
  • Stress cracking from velocity and turbulence

By restoring the tube wall, repair liners prevent further damage to the parent tube while maintaining proper sealing within the tube sheet.

Curran’s Hydraulic Expansion Process

Curran uses a hydraulic expansion method for tube-end ferrules, sleeves, and full-length alloy liners. This ensures:

  • Uniform 360° contact with the parent tube down the full length of the liner
  • Enhanced wear resistance and corrosion protection
  • Restoration of tube wall thickness
  • Reliable sealing integrity within the tube sheet

Liners and ferrules serve as a durable barrier, combating corrosion and process-induced wear while extending service life beyond routine turnarounds.

Hydraulic Expansion Specs: 6,500–7,500 PSI to guarantee full engagement and long-term performance.
