Heat Exchangers

High Pressure Shell and Tube Heat Exchangers

Struthers Wells has supplied several thousand heat exchangers for essentially every type of application and in virtually every commercially available alloy. Heat exchangers have been designed for design pressures up to 7,900 psig, design temperatures up to 1600 F, and in sizes up to the maximum shipping limitations.
As one of the original founders of Tubular Exchanger Manufacturers Association (TEMA), and a charter member of Heat Exchange Institute (HEI), Struthers Wells has contributed in developing numerous standard mechanical, thermal, fluid, and vibration algorithms and calculation methods that have been the basis for many current modern computer programs used by many industry leaders.

Multi-wall Shell Construction
To overcome thick shell rolling limitations in the late 1950s, Struthers Wells developed a proprietary laminated shell called Multi-wall construction. Multi-wall vessels are utilized for Ammonia Converters and Urea Reactors. Due to the process fluids, the inner layer of the vessel is alloy material, such as Stainless Steel, Titanium, or Zirconium. The Multi-wall vessel solves many material and fabrication problems and presents a competitive design when compared to mono-wall vessels.
