Overview

HOLIDAY TESTING (also known as Spark Testing or Continuity Testing) is a non-destructive testing (NDT) method used to detect pinholes, voids, and discontinuities in protective coatings applied to pipelines, storage tanks, pressure vessels, and concrete surfaces. It ensures coating integrity, preventing corrosion and premature failure in industries such as oil & gas, petrochemical, marine, and construction.

• Benefits of PMI:

  • Ensuring coating integrity: Holidays can lead to corrosion and premature coating failure. 
  • Quality control: Holiday testing is a crucial part of a quality control program for coating systems. 
  • Preventing costly repairs: Identifying and repairing holidays early can prevent costly repairs or replacements later.
