Retubing or tube replacement is a specialized maintenance service involving the removal of damaged, corroded, or fouled tubes from heat exchangers, boilers, condensers, or chillers and the installation of new tubes. This process restores mechanical integrity, ensures efficient heat transfer, and extends the operational life of critical thermal equipment.

• Comprehensive Tube Removal & Installation:- Involves safe extraction of old tubes and precise insertion, rolling, or welding of new ones.

• Material-Specific Replacement Options:- Replacement tubes available in carbon steel, stainless steel, copper, brass, titanium, or other alloys based on process requirements.

• Restores Heat Transfer Efficiency:- Eliminates leak-prone or clogged tubes, improving thermal performance and reducing energy consumption.

• Leak-Proof Expansion & Welding:- Tubes are expanded hydraulically or pneumatically and optionally seal-welded for secure, long-lasting joints.

• Non-Destructive Testing (NDT):- Includes eddy current testing, hydrotesting, and visual inspection to ensure integrity before and after replacement.

• On-Site Execution Available:- Performed on-site with portable equipment for quick turnaround during plant outages or scheduled shutdowns.

• Applicable to All Heat Exchanger Types:- Suitable for boilers, air-cooled heat exchangers, condensers, feedwater heaters, and evaporators.
