Hairpin Heat Exchanger | Double Pipe Section / Multitube Hairpin | Single Pass U-Bundle Materials: CS/304/316L/Ti | Design Temp -40°C to +500°C | Applications: High ΔT Services / Vaporizing / Gas Heating | Manufactured per TEMA or ASME VIII-1 Technical Advantage Overview The hairpin heat exchanger (also known as a double-pipe or multitube hairpin) is engineered for services where thermal expansion differential between the tube and shell fluids exceeds the practical limit of a
Desalted Crude Oil Side Draw Heat Exchanger (TEMA AES) for Petrochemical Industry YUHONG unit is a TEMA Class R shell-and-tube heat exchanger engineered for the atmospheric crude distillation train, positioned immediately downstream of the desalter. It handles desalted crude oil tapped from the side-draw of the atmospheric column (or the pre-fractionator circuit) and exchanges heat against a secondary process stream — typically a pump-around reflux loop, preheater train
