Heat Exchanger Tube – The Heart of Shell & Tube Heat Exchangers

Understanding Heat Exchanger Tubes and Their Selection

Heat exchanger tubes are the primary components of shell and tube heat exchangers – the most common type of heat transfer equipment used in power plants, chemical plants, refineries, and HVAC systems.

What Makes a Good Heat Exchanger Tube?

Good thermal conductivity

– Efficient heat transfer between fluids

Smooth surface

– Minimizes fouling and pressure drop

Ductility

– Allows tube expansion into tubesheets

Corrosion resistance

– Withstands the process fluid

Dimensional accuracy

– Consistent tube-to-baffle fit

Material Selection

Material	Best For	Limitations
Low carbon steel (A179)	General purpose, fresh water	Not for seawater
Stainless steel (TP304, TP316)	Corrosive fluids, seawater	Higher cost
Copper alloys	Marine, seawater	Limited temperature

Tube Expansion

Heat exchanger tubes are typically expanded (rolled) into tubesheets to create a leak-tight joint. The low hardness of ASTM A179 (≤72 HRB) makes it ideal for this purpose.
