DEVELOPMENT OF A COST EFFECTIVE POWDER COATED MULTI-COMPONENT COATING FOR PIPELINES

摘要

Pipelines are used globally to transport a variety of rnaterials including gas, crude, petroleum products as well as water.To a great degree, they fulfill a range of demands to provide safe and low cost conduits. Currently, more and more pipelines arebeing called upon to perform for durations beyond their planned life. In addition, the pipelines are being used for different mediabeing transported under new conditions, not anticipated in the original design. Pipeline coatings are selected on the basis ofproduct cost with less emphasis given for the impact of coating types on overall project costs or on asset integrity beyond theplanned life. In view of this, there has to be some rethinking of the design and selection philosophy regarding pipeline coating.This will lead to an increasing demand for innovative and better perfomaing external corrosion coating systems to ensure pipelineassets are well protected and retain their value even after their planned assignments have been completed. This paper comparesconventional Fusion Bonded Epoxy (FBE) coating against an innovative powder coated multi-component coating. Economicbenefits of this coating system, particularly in the significant phases of new pipeline installations such as transportation, fieldstorage, construction, and operational service are discussed.
