11104 Design Aspects Summary

Avoiding or more realistically minimizing corrosion risk stems from a simple application of existing knowledge and a good deal of common sense. Following the comments made previously and adopting elementary design considerations, material lifetimes may be extended.

In summary some of the following design aspects should be considered:

• Prevent stress concentrations, changes in section and sites for solution accumulation.

• Avoid changes in pipe bore.

• Avoid galvanic coupling where less anodic material has unfavorable area ratio.

• Apply correct material selection.

• Prevent excessive operating conditions.

• CP or AP may be more economical than design changes but avoid excessive current densities.

• Avoid mechanical damage to coating systems.
