Engnineering Capabilities
REPL engineers uses the latest design software to provide the quickest proposal turnaround and the most efficient use of space and materials. The Expansion Joint design is achieved by a combination of practical experience and technical knowledge backed up severval software programs (ETMA & ASME).
Finite Element Analysis and Pipe Stress Analysis software are used to simulate the load and resulting stresses that may occur in a design system.
These computer programs help pre-determine engineering design specifications to meet load/stress requirements.
REPL can provide units, design, fabricated and tested in accordance to standard codes.
