Developing Field Test Procedures for Chloride Stress Corrosion Cracking in the Arabian Gulf

Abstract EN

Oil and gas production and petrochemical plants in the Arabian Gulf are exposed to severe environmental conditions of high temperature and humidity.

This makes these plants susceptible to chloride-induced stress corrosion cracking (CSCC).

The laboratory testing fails to provide the exact field environmental conditions.

A cost efficient field test setup for CSCC was designed and developed for the Arabian Gulf.

The setup included designing self-sustained loading devices, samples, and sample racks.

The samples were exposed to a stress equivalent to 80% and 100% of their yield strength.

This paper describes the developed test procedures to establish testing with high level of accuracy and repeatability.

It also discusses the design aspects and the challenges that were met.
