Why Heat Exchanger Retubing Matters in Oil & Gas
Heat exchangers are essential for safe and efficient oil and gas operations. They recover energy, regulate process temperatures, and safeguard equipment across the value chain, from upstream production through refining and petrochemicals. Over time, heat exchanger tubes degrade from thermal stress, corrosion, and fouling.
Retubing restores efficiency, extends asset life, and prevents costly unplanned shutdowns.
Dimpleflo™ Retubing Solutions for Oil & Gas
Proven Benefits in the Field
Energy Savings
Dimpleflo™ retubing restores and enhances heat transfer efficiency, allowing operators to recover more energy from existing exchangers. Improved thermal performance reduces fuel and steam consumption across critical Oil & Gas processes.
Cost Reductions
By extending the service life of existing exchangers, retubing avoids the need for costly replacements. Longer run times between cleanings and retrofit-ready solutions help lower both maintenance expenses and capital investment.
Improved Process Efficiency
Our patented dimpled tube design, applied through retubing, improves flow dynamics, reduces fouling, and ensures consistent heat transfer. The result is stable, reliable performance under the demanding conditions of Oil & Gas operations.
Environmental Impact
Retubing with Dimpleflo™ supports sustainability goals by reducing energy use and emissions. Higher efficiency and longer exchanger life directly contribute to a smaller environmental footprint for Oil & Gas facilities.
Features of Dimpleflo™ Retubing Technology
Enhanced Fluid Turbulence
Our patented dimpled tubing disrupts laminar flow and increases Reynolds numbers, delivering superior heat transfer performance for crude oils, heavy hydrocarbons, and solids-laden process streams after retubing.
High-Pressure Capability
Retubed heat exchangers with Dimpleflo™ tubes are engineered to withstand demanding Oil & Gas duties, performing reliably at operating pressures up to 25 bar.
High-Temperature Performance
Retubing restores heat exchanger reliability in steam and hot oil service, with consistent performance at temperatures up to 250 °C, ideal for pre-heating, separation, and refining applications.
Versatile Fluid Handling
Dimpleflo™ heat exchanger retubing technology can be applied to exchangers handling virtually any pumpable fluid, from produced water and light hydrocarbons to viscous slurries and refinery by-products.
Custom Dimple Configurations
Multiple dimple profiles are available through heat exchanger retubing, engineered to balance turbulence, fouling resistance, and pressure drop for the exact requirements of Oil & Gas processes.
Space-Saving Compact Design
Existing heat exchangers can be retubed with Dimpleflo™ tubing, unlocking up to 50% additional capacity within the same shell or footprint. This reduces downtime, avoids unnecessary capital expense, and maximises the return on existing assets.
Dimpleflo™ Profile Range
for Oil and Gas Heat Exchanger Retubing
Dimpleflo™ heat exchanger retubing solutions are available with a range of engineered dimple profiles designed to meet the demanding conditions of the oil and gas industry. By selecting the correct dimple profile, operators can optimise thermal performance, extend uptime, and significantly reduce operating costs while maximising the life of existing heat exchanger assets.
Shallow Dimple Profile
Optimised for retubed heat exchangers handling low-density media such as natural gas and process vapours. The shallow profile achieves efficient thermal transfer with minimal pressure drop, making it well suited to gas treatment and vapour recovery duties.
Standard Profile Range
The standard profile for retubed heat exchangers in Oil & Gas operations, balancing flow capacity with heat transfer performance. Ideal for water, crude oil, and common process fluids, it ensures reliable efficiency across upstream, midstream, refining, and petrochemical applications.
Heavy Profile Range
Engineered for retubed heat exchangers managing high-viscosity or fouling fluids such as heavy hydrocarbons, slurries, and solids-laden produced water. The heavy profile delivers strong thermal efficiency, extended run times, and easier cleaning under the most challenging Oil & Gas operating conditions.

Still have questions? Contact us to discuss your specific oil and gas heat exchanger retubing requirements and applications.
What role do heat exchangers play in Oil & Gas operations?
Heat exchangers regulate process temperatures, recover energy, and protect critical equipment across upstream production, refining, and petrochemicals. Over time, tubes wear, corrode, or foul, reducing efficiency. Heat Exchanger Retubing with Dimpleflo™ restores performance and extends the life of these critical assets without full replacement.
What types of fluids can retubed heat exchangers handle?
Dimpleflo™ heat exchanger retubing is engineered for the full range of oil and gas fluids, from crude oil and produced water to heavy hydrocarbons, refinery byproducts, and gas-processing streams. Even challenging fluids with solids or high viscosity can be handled efficiently with retubed dimpled tubes.
Why is fouling such a challenge in Oil & Gas heat exchangers?
Deposits such as waxes, salts, and solids reduce thermal performance and increase operating costs. In the oil and gas industry, fouling is especially problematic due to the nature of process fluids. Heat exchanger retubing with Dimpleflo™ reduces fouling and extends run times, lowering the frequency of cleaning and maintenance.
How does Dimpleflo™ heat exchanger retubing reduce fouling compared to conventional tubes?
Dimpleflo™ uses patented dimpled tube profiles that increase turbulence and disrupt laminar flow. This design keeps heat exchanger tube surfaces cleaner, delivering more consistent heat transfer and reducing downtime caused by fouling.
What pressure and temperature ranges can Dimpleflo™ retubed exchangers handle?
Retubed Dimpleflo heat exchangers are proven to operate reliably at pressures up to 25 bar and temperatures up to 250 °C, making them suitable for crude heating, gas conditioning, steam service, and hot oil applications common in the oil and gas industry.
Can existing shell-and-tube heat exchangers be retubed with Dimpleflo™?
Yes. Dimpleflo™ technology is retrofit-ready and can be installed into existing shells through retubing. This approach restores capacity, improves efficiency, and extends service life while avoiding the high costs of new heat exchanger equipment.
Is Dimpleflo™ heat exchanger retubing suitable for offshore Oil & Gas platforms?
Absolutely. Dimpleflo™ heat exchanger retubing is designed for harsh operating environments, including offshore platforms where space is limited and reliability is critical. The compact design and corrosion-resistant materials make it well-suited to offshore conditions.
How does Dimpleflo™ heat exchanger retubing support sustainability goals?
By improving heat recovery and reducing energy use, Dimpleflo™ heat exchanger retubing directly lowers fuel consumption, steam demand, and CO₂ emissions. Extending the life of existing heat exchangers also reduces capital waste and environmental impact.
What maintenance requirements should operators expect after retubing heat exchangers?
With Dimpleflo™’s dimpled tubes, fouling is significantly reduced, meaning heat exchangers require less frequent cleaning. When cleaning is needed, the design allows easier access, reducing downtime and maintenance costs.
Which materials are available for Dimpleflo™ heat exchanger retubing?
Dimpleflo heat exchanger retubing is available in stainless steel, duplex, and high-alloy materials, designed for the corrosive, erosive, and high-temperature conditions found in oil and gas operations.
