Materials Used in Shell & Tube Oil Cooler Tubes
The tubes in a shell and tube oil cooler are critical for heat transfer efficiency, corrosion resistance, and durability. The choice of material depends on factors like fluid compatibility, temperature, pressure, and cost. Below are the most common materials used:
1. Copper & Copper Alloys
- Common Types:
- Copper (Pure) – Good thermal conductivity, but soft and prone to erosion.
- Admiralty Brass (Cu-Zn-Sn) – Resists corrosion in freshwater and mild chemicals.
- Aluminum Brass (Cu-Zn-Al) – Better for seawater cooling (resists biofouling).
- Advantages:
- Excellent heat transfer (high thermal conductivity).
- Good corrosion resistance in clean water/oil systems.
- Disadvantages:
