Nonmetallic composites increasingly find applications in almost all process industries. The tremendous
technological advancements in the polymer industry remarkably improved corrosion resistance
characteristics. Other encouraging aspects such as light weight, longer life cycle than conventional
materials, lower operating and maintenance costs can be of great significance to justify the higher capital
cost in specifying composites for new projects. In line with the nonmetallic composites enrichment
program, one of the largest gas processing plants in Saudi Arabia deployed nonmetallic materials in
structural, corrosion resistance, rehabilitation, life extension of concrete structures, safety and reliability
enhancement applications.
This paper is an update on the performance review of these applications at ‘Uthmaniyah Gas Plant in
critical streams, such as the cooling water system and hydrocarbon pipelines, ongoing efforts to promote
and maximize similar applications in other operating units.
