Fiberglass Engineering Services
FRP (Fiber Reinforced Plastics) piping systems, unlike traditional systems, require specialized design, manufacturing, and installation due to their anisotropic properties. Dynaflow Research Group, has been involved in the development of FRP for pressurized applications since its founding in 1989.
As a founding member of the ISO14692 and DNV certification committees, DRG has contributed to many technical papers and industry codes. Our engineering services cover the entire project life-cycle, from feasibility studies to installation support.Â
Renowned companies such as Shell, BP, BASF, and many more rely on our expertise for FRP systems. Our deep involvement in international standards ensures up-to-date, globally recognized solutions.

FRP DESIGN & QA SUPPORT
Advanced Design Support for Reliable Fiberglass Piping Systems
An optimized design in the early project stages is key to preventing future operational issues. Our fiberglass piping design support ensures durability and efficiency by selecting the right materials, optimizing pipe wall thickness, and ensuring proper support layouts.
By using advanced tools like Finite Element Analysis (FEA), we ensure your fiberglass components—vessels, tanks, and more—are designed to withstand operational demands. This attention to detail minimizes costly delays, equipment failures, and unplanned downtime, ultimately reducing time and costs throughout the project’s lifecycle.
