COATINGS FAILURE ANALYSIS

Exploring Epoxy Coating Failures with ExcelPlas Labs
While epoxy coatings are generally durable and effective at preventing corrosion, there are a few common types of epoxy coating failures that can occur:

  • Adhesion failure: This occurs when the epoxy coating fails to properly adhere to the surface of the pipe, which can be caused by factors such as improper surface preparation or a poorly formulated coating. Adhesion failure can result in the coating peeling or flaking off, exposing the underlying steel surface to corrosion.
  • Blistering: This occurs when small bubbles or blisters form on the surface of the epoxy coating, which can be caused by improper surface preparation, moisture contamination, or excessive heat during curing.
  • Cracking: This occurs when the epoxy coating develops small cracks, which can be caused by factors such as thermal expansion and contraction, improper coating thickness, or exposure to chemicals.
  • Delamination: This occurs due to intercoat or interfacial adhesion failure due to the presence of a weak boundary layer such as silicone or hydrocarbon oil contamination.

Critical Questions for Protective Coatings for Asset Protection in Oil & Gas, LNG:

  • Why is the coating not stopping corrosion?
  • Why is the coating delaminating or blistering?
  • Has the coating been correctly specified / applied?
  • Does the coating meet the manufacturing standard, including properties such as correct hardness/cure, adhesion and thickness?
  • What surface preparation and atmospheric conditions must be achieved to successfully apply the coating?
  • Does the coating have any defects in it? How will these affect performance?
  • Why did the coating fail? Root cause assessment.
  • How can the coating be successfully repaired/remediated so that it doesn’t fail again?

ExcelPlas Labs can answer these questions and more…

This newsletter is brought to you by ExcelPlas Coating Labs (http://www.excelplas.com/)

ExcelPlas Labs provides independent testing, analysis, and investigation on protective coatings to prevent corrosion.

ExcelPlas has extensive analytical capabilities for testing of Protective Coatings and Insulation Consulting for major oil and gas companies.

We conduct corrosion surveys, coating sampling, coating analysis, and testing to ensure coating specifications for a wide range of onshore and offshore clients in Australia and the Asia-Pacific Region.

ExcelPlas Labs offer a full range of coating testing and analytical services to Australia’s mining, oil, gas, and infrastructure sectors.

Forensic analysis for undertaking various coating-based failure investigations and problem-solving.

ExcelPlas Undertakes Analysis & Testing of Polymer Coating Systems including:

  • Epoxy Protective Coatings
  • Epoxy-Phenolic Protective Coatings
  • Fusion bonded epoxy (FBE) 
  • Dual-Layer Fusion bonded epoxy (DLFBE)
  • Liquid applied epoxy (LAE)
  • Abrasion-resistant overcoat (ARO)
  • Three-layer PE (3LPE)
  • Multi-component liquid spray  (MCL)
