Pipeline operating temperature directly impacts material properties, corrosion rates, thermal stress, and fluid behavior — making it a critical parameter for pipeline integrity management.

Pipeline operating temperature directly impacts material properties, corrosion rates, thermal stress, and fluid behavior — making it a critical parameter for pipeline integrity management. Temperature fluctuations cause thermal expansion and contraction, generating axial stresses that contribute to bending strain, buckling, and fatigue.

Key temperature-related pipeline concerns include:
• Thermal stress and pipeline movement from temperature cycling.
• Accelerated corrosion rates at elevated temperatures.
• Corrosion Under Insulation (CUI) risk in specific temperature ranges (-4°C to 175°C).
• Brittle fracture risk at low temperatures.
• Flow assurance issues (wax deposition, hydrate formation).

EMPIT’s CMI technology addresses temperature-related integrity threats by detecting bending strain, pipeline movement, and corrosion from the surface — providing operators with data to assess thermal effects on pipeline condition without excavation.
