Summary

Design configuration with respect to corrosion has a critical role to play in the service life of components. The following points should be noted while designing components for an optimum life:

• Design methods: Proper design methods are as important in controlling corrosion as proper selection of materials. Materials and design are complimentary to each other and neither of the two can be ignored.

• Specifications: Follow strictly the specifications regarding material selection, temperature sensitivity, coating, insulation, flow velocity, accessibility, fabrication, storage and so on in order to avoid unforeseen failures and costly subsequent repairs.

• Replacements: Design replaceable parts for the systems which are most likely to corrode.

• Accessibility: Good designs allow uniform coating to be applied on the surface whenever required. Areas of uneven coating are potential sites for corrosion initiation. Sufficient space should be allowed for proper coating maintenance.

Remember, a good design can go a long way in providing a save environment and a maximum return on capital.
