Hairpin Heat Exchanger

Hairpin heat exchangers use true counter-current flow. Unlike multi-pass shell-and-tube designs where correction factors are used to account for inefficiencies resulting from co-current passes, this process maximizes temperature differences between shellside and tubeside fluids. Owing to its fewer sections and less surface area, a hairpin heat exchanger is the most efficient design when a process requires a temperature cross (hot fluid outlet temperature is below cold fluid outlet temperature).


The ever increasing processing capacity of LNG storage and processing plants challenges for even bigger hairpin exchangers, often the preferred design to withstand the demanding process requirements of this application. IMB is a leader in the manufacturing of big hairpins (ND > 20”) and has references of this and other types equipment’s manufactured specifically for the LNG storage and processing plants.


Since years world has experienced a continually growing energy demand and this will be the trend also for the future. All major countries are looking for alternative energy sources. In this scenario, renewable energies are one of the solutions to environmental problems and Concentrated Solar Thermal Power (CSP) generation is among the most promising.
