Retubing

Problem

Tube bundles in Air Preheaters (APH) and heat exchangers can suffer from corrosion, fouling, and wear, leading to reduced efficiency, increased downtime, and higher maintenance costs. Retubing is needed to restore performance.

Solution

1. Inspection: Assess the damage to determine the extent of retubing required.
2. Tube Removal: Use specialized tools to safely remove damaged tubes.
3. Cleaning: Clean the shell and components before installation.
4. Retubing: Install new tubes with precision to ensure proper function.
5. Testing: Conduct pressure and leak tests to confirm the system is operational.
