This edition of Damage Control will offer practical steps to mitigate different forms of wet H2S damage and help to minimize long-term inspection and maintenance costs related to wet H2S damage.

November/December 2021 Inspectioneering Journal

This issue of Damage Control offers a perspective on how to assess the different forms of wet H2S damage using modern FFS and computational analysis techniques with the safe operation of damaged pressure vessels, piping, and associated components.

September/October 2021 Inspectioneering Journal

This article summarizes the fundamentals of wet H2S-related damage mechanisms, offers some practical inspection guidance, and reviews a notable industry failure caused by different forms of wet H2S damage.

July/August 2021 Inspectioneering Journal

Practical steps to mitigate corrosion under insulation (CUI) damage on fixed pressure equipment and commentary on common mitigation techniques and good engineering practices for external insulation or fireproofing system design and application.

May/June 2021 Inspectioneering Journal

In this article, FFS assessment methods are summarized and practical guidance is offered for qualifying CUI damage on carbon and low-alloy steels.

March/April 2021 Inspectioneering Journal

Corrosion under insulation is a form of external corrosion that is caused by trapped water on insulated surfaces. It is an industry problem affecting equipment in the oil and gas, petrochemical, specialty chemical, fertilizer, and related industries.

January/February 2021 Inspectioneering Journal

Thermal fatigue, a specific form of fatigue driven by varying metal temperature gradients and ensuing differential thermal expansion, is generally most effectively mitigated by reducing the severity of metal temperature gradients.

November/December 2020 Inspectioneering Journal

Conventionally, three primary fatigue analysis methods have been used to estimate fatigue life; these are the stress-life (S-N) approach, the strain-life (ε-N) approach, and the fracture mechanics (crack growth) approach.

September/October 2020 Inspectioneering Journal

This article reflects the first in a series on damage mechanisms that will appear in this recurring Inspectioneering column entitled “Damage Control.” The inaugural topic discussed in this column is thermal fatigue.

May/June 2020 Inspectioneering Journal

This article provides an overview of brittle fracture, details on several industry failures, and a summary of deficiencies and concerns with current published methods for screening susceptibility of equipment to potential brittle fracture failures.

January/February 2018 Inspectioneering Journal

Given the concern throughout industry regarding the potential for brittle fracture failures, PWHT guidance to address potential issues arising from the recent changes in PWHT code requirements for carbon steel is examined in this article, and commentary on the potential reduction in fracture toughness due to PWHT is provided based on a review of published literature.

July/August 2016 Inspectioneering Journal

This article summarizes a recent finite element analysis (FEA)-based study that employs creep simulation techniques to investigate the elevated temperature response of piping with peaked longitudinal weld seams.
