#ndt TWI Ltd has recently launched a new Joint Industry Project to explore and validate detection methods for high temperature hydrogen attack (HTHA). Inspections will be carried out on a carbon steel pressure vessel – operated in a regime calculated to induce accelerated HTHA – and designed to simulate the real world operations and challenges associated with detecting this phenomenon.

Carbon steels are used extensively in oil and gas refinery equipment, and have fallen victim to HTHA, as is evident from the
