“We are experts in Pipe Stress Analysis”
An insight into our Pipe Stress Analysis!

Flexibility Analysis or better known as Pipe Stress Analysis is the “black art” in mechanical engineering. It is NOT finite element analysis (FEA) but an advanced version of ‘Stick & Beam Theory’ using analysis tools such as, AutoPIPE Bentley or CAESAR II softwares. If you don’t allow for thermal expansion, pressure, dead weight, water/steam hammer, creep, fatigue or corrosion of steel pipes, these pipes will rupture and fail, the question is not “if”, but “when”?
At Design Stress Ltd., we have a combined team experience of over 110 years solving stress-related issues for clients across many industries including nuclear, defence (submarines), new build, oil & gas, process plant and renewable energy. It is this breadth of experience that enables us to identify potential difficulties and solve problems cost effectively.
