Full-length alloy tubes hydraulically expanded inside existing parent tubes to provide corrosion and erosion protection. Available in stainless steel, duplex, Inconel, CuNi, C276, and other specialized metallurgies for upgrade applications.
Heat exchanger tubes experience corrosion, erosion, and tube-end wear from aggressive process media and debris. Traditional responses include plugging tubes or replacing entire units.
Typical impact from extensive plugging
Full-length hydraulically expanded liners provide metal-to-metal contact barrier protection while maintaining heat transfer efficiency. Onsite installation minimizes downtime.
Restored tube functionality
Hydraulically expanded liners provide immediate corrosion protection while maintaining operational efficiency through proven metallurgy upgrades and expert installation.
Restore compromised tubes to full service capacity, avoiding volume losses from plugging strategies.
Protect parent tubes from further degradation through specialized alloy barriers designed for specific process conditions.
Avoid premature unit replacement through targeted tube rehabilitation that addresses root cause failures.
Maintain optimal performance through metal-to-metal contact installation that prevents insulating air gaps.
Complete installations within typical turnaround windows through efficient onsite processes and small crew requirements.
Access specialized alloys including 316SS, 825, C276, and duplex materials for enhanced corrosion resistance.
Select appropriate alloy based on process conditions and order properly sized annealed liners
