Materials: Services: Corrosion Management
_ Services: Corrosion Management

The corrosion management expertise offered by INTEC is listed below:

  • Cause and effects of corrosion.
  • Causes of failure to pipelines, risers and subsea equipment.
  • Forms of corrosion - galvanic, crevice, pitting, preferential weldment corrosion, corrosion fatigue, inter/intragranular, SCC, SSC and HIC, SOHIC, MIC
  • Internal and external corrosion mechanisms on pipelines, subsea structures/components, topsides components, piping.
  • Corrosion theory, anodic / cathodic reactions, polarization diagrams, Evans diagram, principles of cathodic protection, over potentials, galvanic series/couples.
  • Cathodic protection systems for subsea components, offshore pipelines, offshore structures and onshore pipelines and tanks and terminals.
  • Chemical inhibition recommendations.
  • Ensuring that compatible coatings are used.
  • Specifying and checking coatings before, during and after application.
  • Coatings selections for pipelines, risers and subsea structures and topsides, eg coal tar, FBE, polyolefinics, 3 layer systems, PU, insulation.
  • Coating testing (laboratory and field) – cathodic disbondment, impact, high temperature, high pressure, collapse, sour service.
  • Selecting, specifying and checking cathodic protection monitoring systems and site surveys.
  • Field joint coating materials selection, design and application methodologies.
  • Corrosion monitoring by coupons, ER, LPR probes.
  • Hydrate prevention (methanol).
  • Dehydration systems (MEG/TEG).
  • Dew point control.
