Shell-and-Tube Heat Exchanger

Technical Specifications of Shell-and-Tube Heat Exchanger

The Shell-and-Tube Heat Exchanger is one of the most widely used heat exchange devices in industrial applications, suitable for high-pressure, high-temperature, and complex fluid conditions. Its core parameters are as follows:

1. Key Technical Parameters

Parameter	Typical Value/Range	Remarks
Design Standard	ASME VIII Div.1 / TEMA / GB 151	International standards
Heat Transfer Area	1~2000 m²	Custom sizes available
Design Pressure (Shell/Tube Side)	0.6~15 Mpa (6~150 bar)	Ultra-high-pressure models up to 30 Mpa
Design Temperature	-196°C to +600°C	Cryogenic to high-temperature range
Shell Material	Carbon Steel (Q345R) / SS304 / SS316L / Hastelloy	Corrosion-resistant options
Tube Bundle Material	SS304 / SS316L / Copper-Nickel Alloy / Titanium	Anti-fouling design
Tube Diameter/Length	Φ10~Φ50 mm / 1~12 m	U-tube/straight tube options
Tube Sheet Connection	Welded / Expanded / Welded + Expanded	Leak-proof design
Number of Tube Passes	1~8 passes	Multi-pass optimization
Baffle Type	Single/Double Segmental / Disk-and-Doughnut	Controls shell-side flow
Connection Standard	ANSI / DIN / GB / JIS Flanges	DN25~DN1000

2. Structural Features

o Multi-Pass Design – Increases temperature difference (ΔT) by adding tube passes.
o Anti-Vibration & Erosion Resistance – Baffles optimize shell-side flow and reduce tube vibration.
o Modular Maintenance – Removable tube bundle (floating head/AES type) for easy cleaning.
o Enhanced Heat Transfer – Optional corrugated/spiral tubes for higher efficiency.

3. Typical Applications

o Petrochemicals: Crude oil preheating, reactor cooling, solvent condensation
o Power & Energy: Boiler feedwater heating, condensers
o Pharma/Food: Fermentation tank temperature control, pasteurization
o Marine Engineering: Central cooling systems

4. Data Required for Selection

o 1.Fluid Properties (composition, phase, corrosiveness, fouling tendency)
o 2.Process Parameters (flow rate, inlet/outlet temperatures, pressure)
o 3.Pressure Drop Limits (allowable shell/tube side pressure drop)
o 4.Cleaning Requirements (need for removable design)

5. Advantages

o High Pressure/Temperature Resistance – Withstands extreme conditions up to 30 Mpa/600°C.
o Long Service Life – Corrosion-resistant materials + anti-fatigue structure.
o Flexible Configuration – Supports multi-pass and multi-material combinations.

6. Comparison with Other Heat Exchangers

Feature	Shell-and-Tube	Plate Heat Exchanger	Plate-Fin Heat Exchanger
Pressure Rating	High (≤30 Mpa)	Medium (≤2.5 Mpa)	Medium (≤8 Mpa)
Temperature Range	-196°C to +600°C	-50°C to +200°C	-269°C to +200°C
Compactness	Low (large volume)	High	Very High
Maintenance Cost	Medium (higher for removable types)	Low (easy plate cleaning)	High (fully welded, hard to repair)

Note: Shell-and-tube heat exchangers can be customized as fixed tube sheet (BEM), floating head (AES), or U-tube (BEU) types based on process needs.
