Fiberglass Reinforced Plastic

Engineering for Piping Systems

About the course

Fiberglass Reinforced Plastic (FRP) piping, or Glass Reinforced Plastic (GRP) piping, offers a cost-effective alternative to corrosion-prone metallic and non-reinforced thermoplastic pipes. However, designing FRP systems requires specialized knowledge due to fundamental differences from steel piping design.

This course provides comprehensive training in the fundamentals of designing and working with FRP piping systems. It equips you with a solid understanding of material properties and behaviors alongside their impact on designs, covers the engineering process, including pipe stress analysis, and offers numerous real-life field examples to illustrate critical aspects of FRP systems.

The course is comprised of 8 online video modules, with 1-year unlimited access to the course materials and discussion forum for ongoing knowledge refreshment in support of your projects.
