                   5.1 Factors Affecting Materials Selection

                   *  Structural, production and process components are fabricated using different

                      materials  including  carbon  steels,  corrosion-resistant  alloys,  concrete,

                      ceramics,  elastomers,  plastics  and  composites.  Proper  materials  selection

                      requires a clear definition of the following operating conditions, as well as

                      consideration  of  the  electrochemical,  mechanical  and  processing

                      compatibility amongst the different materials:

                   *  1. Operating loads and environment

                   *  2. Possible extreme and upset conditions

                   *  3. Special operating practices

                   *  4. Operating temperature

                   *  5. Corrosivity of production fluids and external environment

                   *  6. Corrosion control strategy

                   *  7. Service life

                   *  8. Maintenance flexibility

                   *  9. Environmental restrictions

                   *  10. Regulations
