Pipes, line pipes and pressure vessels
At Investmech, we offer the following:
- Strain, acceleration and temperature measurements on high temperature pressure vessels, ladles, refractory, furnaces, steam pipes, etc.
- Strain and acceleration measurements and control on pipes.
- Remaining life prediction of underground pipes subjected to various environmental conditions.
- Modal analysis and operational mode extraction on pressure vessels
Previous Work
Pressure vessel fatigue
Design and fatigue assessment on pressure vessels using ASME and PD codes.
Fit-for-purpose calculations on flawed water line pipe
- Determine flaw size dependent design pressure
- Fracture Mechanics to predict crack growth and failure mode
Corrosion of pipelines
- Monte Carlo and Fracture Mechanics calculations to calculate remaining life of cyclically pressurised underground and surface line pipe life subject to environment dependent pit corrosion depth and density distribution.
