Main Objective

To establish the effectiveness of cathodic protection in mitigating stress corrosion cracking (without causing hydrogen damage) for a range of high-strength pipeline steels from X-70 to X-120, and to assess the effects of overprotection and underprotection.

Public Abstract

This project will be carried out to assess the effect of cathodic protection to produce hydrogen that can cause cracking and in-service failures of high-strength pipeline steels, from X-70 to X-120, and to establish the effectiveness of cathodic protection (CP) in mitigating stress corrosion cracking (SCC) in these steels.
