In high-demand industrial environments, the efficiency and reliability of your heat exchangers are vital to uninterrupted operations. At Quintel, we specialize in heat exchanger retubing—a critical maintenance process that restores performance, extends service life, and prevents costly downtime.

Why Retubing Matters

Over time, the tubes in a heat exchanger—particularly in harsh operating conditions—are subject to wear, corrosion, pitting, and fouling. These issues degrade thermal performance and increase the risk of tube leaks, which can disrupt operations and lead to safety hazards. Retubing is a cost-effective solution that revitalizes your equipment without the need for full replacement.

Our Proven Retubing Process

At Quintel, our retubing procedure is designed for precision, speed, and long-term reliability:

1. Thorough Inspection & Assessment

We begin with a comprehensive inspection to evaluate the condition of your exchanger. Using advanced diagnostic tools, we identify tube failures, assess fouling levels, and determine whether retubing is the appropriate solution.

2. Safe and Efficient Tube Removal

Damaged tubes are carefully severed from the tube sheet and extracted using specialized pulling equipment. Our technicians ensure the tube sheet and surrounding components are cleaned and protected to avoid further damage during removal.

3. Precision Tube Installation

New tubes—matched exactly to the original specifications or upgraded for improved performance—are inserted and secured. We use mechanical rolling or hydraulic expansion methods to ensure a leak-tight seal with the tube sheet. For critical applications, welding may be employed to further reinforce the tube-to-tube sheet joint.

4. Rigorous Testing

Each retubed exchanger undergoes hydrostatic testing to confirm pressure integrity and non-destructive testing (NDT) methods such as eddy current or ultrasonic testing to verify tube quality and alignment.

5. Reliable Commissioning and Documentation

After testing, the unit is reassembled, aligned, and recommissioned with detailed documentation for future reference. Our team ensures your system is brought back online smoothly with optimal performance.
