Internal Tube Cutting
Internal tube cutting is a precise process used to remove sections of heat exchanger tubes that cannot be sealed or repaired through external methods such as puncturing or mechanical fit plugs. This technique is essential when leaks occur at the tube-to-tube sheet joint or in applications involving high-pressure differentials, where conventional plugging methods are not suitable.
Metalok Industries utilizes specially engineered internal tube cutting tools capable of cutting and removing tubes up to 2 inches in diameter with high accuracy and minimal damage to the tube sheet.
This process demands specialized equipment and skilled technicians with extensive experience to ensure safe, controlled, and efficient tube removal without compromising the integrity of the heat exchanger.
- Inspect and identify tubes requiring internal cutting or removal.
- Ensure the heat exchanger is fully depressurized, isolated, and drained.
- Obtain necessary safety permits and wear proper PPE.
- Select the correct internal tube cutting tool based on tube size and material.
- Insert the cutter into the tube and position it at the desired cutting depth.
- Operate the tool slowly and evenly to achieve a clean internal cut.
- Avoid excessive force to prevent damage to the tube sheet or adjacent tubes.
- Remove the cut tube section carefully using extraction tools.
- Inspect the tube sheet and surrounding area for burrs or damage.
- Clean the area thoroughly before proceeding with retubing or plugging.
