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.
  • Root cause assessment for collapse of pipes in mine shaft.

Flow and pressure distribution

Investmech did several projects where flow & pressure distribution in water and slurry pipelines were calculated, including heat exchangers.
